阅读理解。     Since the gene, called DAF: 16 in worms, was found in many animals and in humans, the finding could
open up new ways to affect aging, immunity (免疫) and resistance in humans, the scientists said.
     "We wanted to find out how normal aging is being governed by genes and what effect these genes have
on other traits, such as immunity," said Robin May of the University of Birmingham, who led the study.
     Populations across the-world are aging at a surprising pace, bringing potentially big challenges for health
and social care systems. A study by Danish scientists last year found that half of babies born in the rich
world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try
to develop drugs to help them stay healthier as their lives extend.
     "What we have found is that things like resistance and aging tend to go hand in hand," May said in an
interview.
     May"s team compared longevity, stress resistance and immunity in four related species of worm. They
also looked for differences in the activity of DAF-16 in each of the four species, and found that they were
all quite distinct.
     May said DAF-16 was active in most cells in the body and was very similar to a group of human genes
called FOXO genes, which scientists believe play a role in the aging process.
    "The fact that subtle (微妙的) differences in DAF-16 between species seem to have such an impact on
aging and health is very interesting and may explain how differences in lifespan and related traits have arisen
during evolution," May said. 1. In which section may the text appear in a newspaper? [     ]
A. Education.
B. Science.
C. Entertainment.
D. Culture. 2. According to May, _____. [     ]
A. resistance has a lot to do with aging
B. FOXO genes can be found in worms
C. genes play the same role in different species
D. new drugs will change the genes in older people 3. What can we know from the third paragraph? [     ]
A. New ways have been found to affect aging.
B. Babies in the rich world will all live longer.
C. Present social care systems are poorly managed.
D. Aging populations are causing more challenges. 4. From the text we know that DAF-16 _____. [     ]
A. is a gene that is only found in worms
B. can make people live longer
C. has an effect on aging and immunity
D. has been quite familiar to scientists 5. What can be the best tide of the passage? [     ]

阅读表达。阅读下面短文，请根据短文后的要求进行答题（请注意问题后的字数要求）。      [l]The harmful effects on children were summed up last year in a report by the National Research Council
and Institute of Medicine. Problems begin early, as the infants of depressed mothers cry more than other babies.
They have greater fear of strangers and less tolerance for frustration. Starting in preschool and across all stages
of childhood, they have more behavior problems at school and higher rates of depression and anxiety disorders.
     [2]By adolescence, children with depressed parents have poorer social relations than the teens of parents
____, and they"re more likely to be dependent on alcohol and drugs. Depression in parents also is linked to more
behavior problems at school and higher rates of depression and anxiety disorders, according to studies in the
report.
     [3]And some harmful effects of growing up with a depressed parent appear to remain into adulthood. A
20-year study on kids of depressed parents found that those with depressed parents suffered about three times
the rate of anxiety disorders and depression by their 30s, and they were in poorer health than peers and much
more likely to be dependent on drugs and alcohol. The study, believed to be the longest ever done, was
published in the American Journal of Psychiatry in 2006. These effects may not only be long-lasting but also
far-reaching. Serious depression affects about one in five American parents, and 15.6 million children live with
an adult who has had major depression in the last year.
     [4]As knowledge about the effects of parental depression has grown, so too has research into how to fight
those effects. Studies suggest, for example, that changing destructive parenting practices and teaching children
good coping strategies can make a big, positive difference in kids. 1. What is mainly talked about in the text? (no more than lo words)
    _____________________________________________________________________________________
2. Which sentence in the text is closest in meaning to the following one? With a better understanding of the
    effects of depressed parents, research is also being conducted on how to prevent those effects.

阅读理解。     As they migrate (迁移), butterflies and moths choose the winds they want to fly with, and they change
their body positions if they start floating in the wrong direction. This new finding suggests that insects may
employ some of the same methods that birds use for traveling long distances. Scientists have long thought
that insects were simply at the mercy of the wind.
     Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because
many long distant trips happen thousands of feet above ground. Only recently have scientists developed
technologies that can detect such little creatures at such great heights.
    To their surprise, though, the insects weren"t passive travelers on the winds. In autumn, for example,
most light winds blew from the east, but the insects somehow sought out ones that carried them south and
they positioned themselves to navigate directly to their wintering homes.
     Even in the spring, when most winds flowed northward, the insects didn"t always go with the flow. If
breezes weren"t blowing in the exact direction they wanted to go, the insects changed their body positions
to compensate. Many migrating birds do the same thing.
    The study also found, butterflies and moths actively flew within the air streams that pushed them along.
By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast
as 100 kilometers an hour. The findings may have real-world applications. With climate warming,migrating
insects are growing in number. Knowing how and when these pests move could help when farmers decide
when to spray their crops. 1. What"s the main idea of the text? [     ]
A. Insects migrate with the seasons.
B. Wind helps insects greatly in migrating.
C. Windsurfing insects have real direction.
D. Scientists have trouble in observing insects. 2. Scientists originally thought that _____. [     ]
A. insects always waited for their favourable winds
B. insects chose the winds they wanted to ride
C. insects were just blown about by the wind
D. insects positioned themselves in the winds 3. It is not easy to study the migrating behavior of the insects because _____. [     ]
A. the little creatures can fly very fast
B. they have no regular migrating courses
C. the wind"s direction is hard to foresee
D. their flight is long and high above ground 4. We can learn from the text that _____. [     ]
A insects fly in the way birds do
B. insects travel more easily in autumn
C. insects never position themselves when flying low
D. insects rest a lot when the wind pushes them along 5. According to the passage, the findings can _____. [     ]
A. increase insects in number
B. instruct farmers when to spray
C. prevent climate warming
D. help protect insects

阅读理解。                                                           Shaping the Future of TV
     Nobody can predict the future of TV with any certainty but some major figures in the industry have
recently put forward their thoughts on what will shape TV of the future.
     The shaping of a personalized television future is starting to take place, says Intel. The chip giant,
who makes the processors found in most personal computers, states that by 2015 there will be just over
12 million devices using IPTV services that will be capable of connecting to over 500 billion hours of TV
& video.
     This supports the idea to make television a more social, personalized and readily accessible device
available anywhere through IPTV services. As more and more people consume TV & video through various
mediums, there is now a greater need to distribute and manage this content.
     As such, companies like TV Genius are accepting this announcement made at Intel"s Developer Forum
(IDF) in the USA by their chief technology officer, Justin Rattner.
     With such a variety of content likely to become available, technology firms will need to assist in making
personalized TV recommendations more readily accessible.
     Mr. Rattner, speaking to the BBC said, "TV will remain at the centre of our lives and you will be able to
watch what you want and where you want. We are talking about more than one TV-capable device for every
man and woman on the planet. People are going to feel connected to the screen in ways they haven"t in the
past."
     One way in which this will happen will also be assisted by a more united service of material combining
including video content, internet content, broadcast content, and personal content.
     This content will become much more accessible through remote devices like mobile phones using IPTV
technology. This means that users will be able to watch their favorite programs away from the traditional
media hub, the home. 1. The author uses the passage mainly to _____. [     ]
A. recommend a new type of TV
B. introduce a possible shape of future TV
C. describe the function of future TV
D. support the new type of TV 2. We know from the passage that the future TV might have major features like _____.
    a. being capable of connecting to many more hours
    b. changing the shape very easily c. receiving programs at any place
    d. displaying the advanced materials e. using services accessing the Internet, video, radio, etc [     ]
A. a, b, c
B. c, d, e
C. a, c, e
D. b, c, e 3. The underlined word"this" in the third paragraph refers to _____. [     ]
A. Intel, the chip giant
B. TV and video
C. readily accessible device
D. widely used IPTV services 4. We can infer from the passage that _____. [     ]
A. the present TV will disappear in the near future
B. the future TV will have a beautiful look
C. people are developing the technology of TV very quickly
D. people will spend more time watching TV at home

阅读理解。                                                     Two Earthquakes in Two Months:
                                    Comparing the Quakes in Haiti (海地) and Chile (智利)
     Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery
walk to learn more about the earthquakes from a specific point, and then do a specific research and
presentation project or response activity. Finally, they seek answers to their unanswered questions.
     Materials Print copies of photographs, charts, documents and other visuals to display, as described
below; computer(s) with Internet access (optional), research materials, handouts.
     Warm-up Choose and prepare a "gallery" of photographs, graphics, news reports and other materials to
display around the room to enable students to consider the 2010 earthquake in Chile.
     Depending on course program, choose materials for the gallery that provide a window on the two quakes,
through one of the following specific points, or the focus of your choice:
     Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to
other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
     Rescue and Aid Considering domestic and international response to the disasters by militaries, governments
and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and
shelter to those affected.
     Related The article Underwater Plate Cuts "400 Mile Gash compares several earthquakes:
     Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
     But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震动) might not be as bad.
For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact
that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (断裂) occurred
only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from
the nearest town, Chillan, and 70 miles from the country"s second-largest city, Concepcion.
    Read the article using the following questions.
     Questions For discussion with others and reading comprehension:
     How does the 2010 Chilean earthquake compare to the 1960 Chilean earthquake?
     Why do scientists believe that the 2010 Chilean earthquake will not cause the same level of damage as
January"s Haitian earthquake did?
     How does the 2010 Chilean earthquake compare to the 2004 Indonesian earthquake?
     What reasons do scientists give to explain why the Indonesian quake caused so much more damage than
the recent Chilean earthquake? 1. Which of the following shows one of the reasons for slighter losses in Chile than in Haiti? [     ]

A. Position

B. Power

C. Building

D. Rescue

2. We can infer that the article Underwater Plate Cuts 400 Mile Gash includes _____.[ ]
A. the causes of the 2010 Chilean earthquake and the 1960 Chilean earthquake
B. the comparison between the 2010 Haitian and the 2004 Indonesian earthquakes
C. the reason for the 2010 Chilean quake being more powerful than January"s Haitian earthquake
D. the reason for less damage in the 2010 Chilean quake than in the 2004 Indonesian earthquake 3. What is the passage most likely to be? [ ]
A. A program for research.
B. A guide to earthquake study.
C. An advertisement for students.
D. An introduction to quakes.

阅读理解。     Quickly, the picture comes alive with hyperlinks (超链接), offering the names of the buildings, towers
and street features that appear in the photo. The hyperlinks lead to information about the history, services
and context of all the features in the photo. You have just hyperlinked your reality.
     That might be a little unbelievable, but the technology exists and is no fevered imagination. This is not
a cool small machine invented for the next James Bond movie; this is a working technology just developed
by European researchers. It could be coming to a phone near you, and soon.
    This, as the marketing types say, is a game changer. It develops a completely new interface (界面) that
combines web-technology with the real world. It is big and fresh, but it goes much further and has much
greater influence.
     The development of the system is most outstanding because image recognition technology has long been
pregnant with promise, but seemed to suffer from an unending labour.
     Now MOBVIS has not only developed image recognition; it has also developed more applications for the
technology; and it has adapted it to the world"s most popular technology: the mobile phone.
     The MOBVIS system completely rewrites the rules for exploration and interaction with your physical
environment. The system begins with panoramas (一连串景象). These panoramas form the basis of a city
database. It can match buildings, towers, banners and even logos that appear in the panoramas.
     A user simply takes a picture of the street feature, MOBVIS compares the user"s photograph to the
panoramas and then identifies the buildings from the picture you take and the relevant links are returned.
     Then you simply click on the Imks, using a touch-screen phone, and the MOBVIS system will provide
information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question. 1. Which is introduced in the passage? [     ]
A. A new game software.
B A popular mobile phone.
C. A cool small machine.
D. An image recognition system. 2. What can we learn about the new technology? [     ]
A. It can only be put into use on mobile phones.
B. It is a little unbelievable and just a fevered imagination.
C. It has taken an unending labor to bring the technology into our lives.
D. It will encourage the users to take more pictures of the street features. 3. What is the right order of the operation of MOBVIS?
    a. A city database forms in the system
    b. MOBVIS recognizes the picture and links are returned
    c. A user touches the links on the phone screen
    d. A user takes a picture of the street feature.
    e. MOBVIS provides information in question[     ]
A. a; e; c; d; b;
B. a; d; b; c; e
C. d; c; e; a; b
D. c; a; e; b; d 4. From the passage, we can infer that _____. [     ]
A. MOBVIS has already been widely used all over the world
B. the writer is trying to promote the sales of the MOBVIS system
C. this new technology will soon be very popular in our lives
D. the sales of mobile phones will decrease as MOBVIS comes on market
