IS THERE LIFE ON EARTH
There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility(可行性) of a manned flying saucer(飞碟) landing on Earth.A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion,based on last week"s satellite landing,” Pro. Zog said,“that there is no life on the Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth"s surface in the area of Manhattan is composed of solid concrete(混凝土)and nothing can grow there. For another, the atmosphere is filled with carbon monoxide(一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. ”
“Are there any other hazards that you discovered in your studies?”
“Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don"t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”
“If what you say is true, won"t this set back the flying saucer program several years?”
“Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”
“Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?”
“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”
小题1:During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can_______.| A．land a satellite with Venus astronauts on Earth | | B．make a firstrate flying saucer | | C．get a Earth Being to Venus | | D．direct a flying saucer into Manhattan |

答案
小题1:A
小题2:B
小题3:A
小题4:A |
解析
小题1:细节题。由第二段中“get valuable information as to the feasibility of a manned flying saucer landing on Earth.”一句可知。金星的科学家已经得到了一些有价值的信息,他们能否发射载有他们的航天员的飞碟到地球上来。
小题2:细节题。短文中Prof.Zog 在回答the Venus Evening Star 记者的提问时说:“the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive”,由此可知是他们必须自带氧气的原因。
小题3:推测题。作者在短文中故弄玄虚,引用“金星人”的话“We don"t know what it is made of”,其目的是讽刺地球人对环境的破坏,不言而喻此处指的是空气污染。
小题4:意图推断题。作者借用金星上的一次记者招待会所表现出来的事实来唤醒人们的环保意识,如果这样发展下去,地球上的人类将被毁灭。 |

A peer is a person who is about the same age as you. Peers affect your life, whether you know it or not, just by spending time with you.
Peers can have a good effect on each other. Maybe another student in your science class taught you an easy way to remember the planets in solar system. Maybe you got others excited about your new favorite book, and now everyone"s reading it.
However, sometimes peers affect each other in another way. For example, one kid in school might try to get another to cut class with him, your soccer friend might try to persuade you to be mean to another player and never pass him the ball, or a kid in the neighborhood might want you to shoplift with him.
Some kids give in to peer pressure because they want to be liked, to fit in, or because they worry that other kids may make fun of them if they don"t go along with the group.Others may go along because they are curious to try something new that others are doing. The idea that “everyone"s doing it ” may influence some kids to leave their better judgments, or their common senses behind.
Peer pressure can be extremely strong and hard to get rid of. Experiments have shown how peer pressure can influence someone to change mind from what she knows for sure is a correct answer to the incorrect answer—just because everyone else gives the incorrect answer!That holds true for people of any age in peer pressure situations.
It can be hard to walk away from peer pressure, but it can be done. Pay attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do. Inner strength and self-confidence can help you stand firm, walk away, and resist doing something when you know better.
小题1:What is the main idea of the passage?| A．Peers have a good effect. | | B．Children give in to peer pressure. | | C．Peer pressure is hard to stop. | | D．Peer pressure. |
小题2:The underlined word “shoplift” probably means to_______.| A．do shopping | B．carry goods for shops | | C．steal in the shop | D．take the lift upstairs in the shop |
小题3:The writer will NOT agree that_______.| A．only children change their correct answers to incorrect ones because of peer pressure | | B．peers have an effect on each other | | C．peer pressure can be got rid of | | D．peers will believe in themselves if there are other peers who agree with them |
小题4:The writer intends to _______ by writing the passage.| A．warn peers to separate from each other | | B．tell peers to follow others | | C．show it is hard to walk away from peer pressure | | D．persuade peers to do what they think is the right thing |

Some kids can"t sit still for long. They have a hard time paying attention to just one thing. They"re easily distracted(分神).They can get very impatient. They hate standing in line or waiting for their turn in a game or activity. They get bored pretty fast. They may also be impulsive—saying the first thing that comes to mind or interrupting someone else who"s talking.
For certain kids, this problem is so severe(严重) that doctors have a name for it: attention deficit hyperactivity disorder, or ADHD. Perhaps as many as 1 out of every 20 kids under the age of 18 have characteristics of ADHD. Often, these kids have trouble getting through school and face other difficulties later in life.
Rizzo started developing the Virtual Classroom in 1999.He wanted to see if he could use it as a tool for testing and treating kids who have attention disorders.
To diagnose(诊断) ADHD, doctors typically test patients by giving them tasks that require attention. As part of one classic test, you watch letters flashed on a computer screen. Every time you see the letter “A” followed by the letter “X”,you have to press the space bar. If you"re paying close attention, you"ll register all the times this combination occurs. If not, you"ll miss some.
The Virtual Classroom makes these tests more efficient, Rizzo says. In one experiment, he gave a group of kids the classic “A-X” test. Instead of looking at a computer screen in a doctor"s office, though, the kids wore headsets that made it look like they were taking the test in a classroom.
“Basically what we found,”Rizzo says,“is that, in 20 minutes of testing with virtual reality,we replicated(复制) a finding that usually requires a couple hours of standard testing with computer screens in the psychologist"s office.”
小题1:The first paragraph mainly tells us _______.| A．how to find a patient with ADHD | | B．the behavior of some kids with ADHD | | C．kids with ADHD cannot sit still for a long time | | D．kids with ADHD are easily distracted |
小题2: Perhaps as many as _______ kids have characteristics of ADHD.
A. one out of every twenty kids
B. five percent kids less than 18 years old
C. one out of twenty kids at the age of 18
D. five percent kids more than age of 18
小题3: In the experiment, patients need to press the space bar, when _______.| A．see letters A following X | B．first see A then see B | | C．see letter X and A | D．see letters A followed by X |
小题4:The main idea of the last paragraph is _______.| A．in virtual classroom, we finish the test in 20 minutes | | B．the standard test with computer screen usually costs several hours | | C．the experiment is easy to do | | D．the result of the experiment |

Every year landslides {滑坡} cause 25 to 50 deaths and $1.5 billion in damage in the United States．They account for 15 percent of the deaths from natural disasters in Europe．And in December, a single event killed more than 200 people in the Philippines．Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties．Shaking drills produce harmful dust and loosen heavy, dangerous debris (米屑)．"It"s quite a risky job," says Giorgio Pezzuto of D"Appolonia, an engineering company in Italy.
D"Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber．"The idea is to operate a machine far away that can drill without a human being on board,"" says Pezzuto, manager for the project, which is supported by the European Commission．Engineers claim that the machine will be faster and cheaper than manual labor．The robot, a large radio-controlled four-legged mechanical spider (蜘蛛), has cost at least $2 million so far．The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope" s stability．Testing should begin in May.
小题1:The underlined word "event" (in Paragraph l) refers to ___.| A．landslide | B．machine | C．earthquake | D．flood |
小题2:The purpose in writing this text is ___..| A．to tell people how serious the damage caused by landslides is | | B．to tell people that sending workers to stabilize mountainsides is a risky job | | C．to introduce a product that can be used to stabilize mountainsides | | D．to show people how to use a new product |
小题3:What does the robot look like? | A．A human being． | B．A spider． | C．A truck． | D．A drill． |
小题4:The biggest advantage of this product is that_________.| A．it will be faster and cheaper than manual labor | | B．it can climb mountainsides, drill holes, insert bars and cement | | C．it can collect data on the slope’s stability | | D．it can drill without a human being on board |

One common mistake is choosing an occupation for its real or imagined prestige (声望) Too many high—school students—or their parents for them— choose the professional field, not 49 the relatively small proportion of workers in the professions or the extremely high educational and personal 50 . The imagined or real prestige of a profession or a "White-collar" job is 51 good reason for choosing it as life"s work. 52 , these occupations are not always well paid. 53 a large proportion of jobs are in mechanical and manual work, the 54_ of young people should give serious __ 55_ to these fields.

A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal an synoptic picture(气象图) of conditions in the atmosphere at a given time.
All students of geography should to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts and all climate conditions in general. Twice a month it issues a 30-day “outlook” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These outlooks are based on an analysis of the upper air levels.
With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(气象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.
小题1: Which is not mentioned in this passage in the following about one characteristic of weather?| A．Fronts. | B．Temperature change. | C．Wind speed. | D．Frost. |
小题2:The observation of weather conditions by satellites is advantageous because
_______.| A．it is modern and sophisticated | | B．it used electronic instruments | | C．it enables man to alter the weather | | D．it gives the scientists information not obtained readily otherwise |
小题3:The word “interpret” in Paragraph 2 most probably means _______| A．explain | B．present | C．modify | D．illustrate |
