阅读理解。     Are you preparing for a big test? If so, you may want to play some basketball in between hitting
the books. Doctors are starting to find more and more information that suggests a connection between
exercise and brain development. Judy Cameron, a scientist at Oregon Health and Oregon Health and
Science University, studies brain development. According to her research, it seems that exercise can
make blood vessels(管), including those in the brain, stronger and more fully developed. Dr. Cameron
claims this allows people who exercise to concentrate better. As she says, "While we already know
that exercise is good for the heart, exercise can really cause physical changes in the brain."
     The effects of exercise on brain development can even be seen in babies. Babies who do activities
that require a lot of movement and physical activity show greater brain development than babies who
are less physically active. With babies, even a little movement can show big results. Margaret Barnes,
a pediatrician(儿科医生), believes in the importance of exercise. She thinks that many learning disabilities
that children have in elementary school or high school can be traced back to a lack of movement as
babies. "Babies need movement that stimulates their five senses. They need to establish a connection
between motion and memory. In this way, as they get older, children will begin to associate physical
activity with higher learning," says Margaret.
     Older people can beef up their brains as well. Scientists from 11 universities studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase
of up to 40 percent after exercising just three hours a week. The exercise does not have to be very
difficult, but it does have to increase the heart rate. Also, just like the motion for infants (婴儿), exercise
for older people should involve some complexity. Learning some new skills or motions, such as with
yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long
time.
     For most people, any type of physical activity that increases the heart rate is helpful. The main goal
is to increase the brain"s flow of blood. And your brain can benefit from as little as three hours of exercise
a week.1. What is the best title of this passage?A. How to exercise
B. How exercise helps the brain
C. How to get good scores on a test
D. How the brain can change2. According to the reading, what is the connection between exercise and brain development?A. Exercise makes us stupid.
B. The brain needs special mental exercise.
C. The more exercise, the bigger the brain.
D. Physical exercise helps us think better.3. Why does the author think that yoga is fit for seniors?A. It is easy to learn.
B. It can be done in groups.
C. It does not increase the heart rate.
D. It includes learning new motions.

     Many people catch a cold in the springtime or fall. It makes us wonder… if scientists can send a man to
the moon, why can"t they find a cure for the common cold? The answer is easy. There are actually
hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn"t a cure
for each one.
     When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and
cause a block in it. You feel terrible because you can"t breathe well, but your body is actually eating the
virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel miserable, but actually your
wonderful body is doing every- thing it can to kill the cold.
     Different people have different cures for Colds. In the United States and some other countries, for
example, people might eat chicken soup to make themselves" feel better. Some people take hot baths and
drink warm liquids (流汁). Other people take medicine to stop Various symptoms (症状) of colds.
     There is one interesting thing to note" some scientists say taking medicines when you have a cold is
actually bad for you. The virus stays in you longer because your body doesn"t have a way to fight it and kill
it.
Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:
     It takes about one week to get over a cold if you don"t take medicine, but it takes only seven days
to ~et over a cold if you take medicine.

     Driving a car is not just handling controls and judging speed and distance. It requires you to predict
what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制药),damaging eyesight, judgement and
coordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below
the drink driving limit, driving will be affected.
      Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain.
Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with
fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up
with any measures like taking a shower or having a cup of tea or coffee.
     The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
     ● 50 milligrams of alcohol per 100ml of blood; or
     ● 22 micrograms of alcohol per 100ml of breath; or
     ● 67 milligrams of alcohol per 100ml of urine(尿液).
     Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of
drink driving will be tested.
     Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a
maximum of HK $25,000 and be sentenced to up to 3 years in prison and punished for 10 drivingoffence points; or temporarily banned from driving.
     The same punishment applies to failing to provide specimens(样本) for breath, blood or urine tests
without good excuse.
      Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of
yourself and other road users, never drive after consuming alcohol.

1. The first paragraph is mainly about ________.
A. the introduction of driving skills
B. the damage of drinking to your body
C. the effect of drinking on driving
D. the process of alcohol being absorbed

2. The underlined word "it" in the second paragraph refers to "________".
A. alcohol   
B. absorption
C. blood  
D. process

3. Which of the following is TRUE according to the passage?
A. Drinking below the drink driving limit has no effect on driving.
B. Alcohol is taken in more quickly when drunk with fruit juice.
C. Having a cup of tea helps to get rid of alcohol from the body.
D. 50 milligrams of alcohol per 100ml of breath is below the drink driving limit.

4. A driver suspected of drink driving________.
A. should provide specimens for testing
B. will be forbidden to drive for 3 years
C. will be punished for 10 drivingoffence points
D. should pay a maximum fine of HK$25,000

     In their book Time to Eat the Dog:The Real Guide to Sustainable Living,Robert and Brenda
 Vale say keeping a mediumsized dog has the same ecological impact as driving 10,000 km a year
in a 4.6 liter Land Cruiser.
     "We"re not actually saying it is time to eat the dog.We"re just saying that we need to think about
and know the ecological impact of some of the things we do and that we take for granted."
     Constructing and driving the jeep for a year requires 0.41 hectares of land,while growing and
manufacturing a dog"s food takes about 0.84 hectares-or 1.1 hectares in the case of a large dog
such as a German shepherd.
     Convincing flesheating cats and dogs to go vegetarian for the sake of the planet is a nonstarter,
the Vales say.Instead they recommend keeping "greener",smaller,and more sustainable pets,such as
goldfish,chickens or rabbits.
     The book"s playful title,and serious suggestion that pet animals may be usefully"recycled",by
being eaten by their owners or turned into pet food when they die,may not appeal to animal fans.
     Annoying as the idea may be,the question is valid given the planet"s growing population and limited
resources,Robert Vale said.
     "Issues about sustainability are increasingly becoming things that are going to require us to make
choices which are as difficult as eating your dog.It"s not just about changing your light bulbs or taking
a cloth bag to the supermarket,"he said.
     "It"s about much more challenging and difficult issues," he added.

1.The authors gave their book the playful title to________.
A.make it amusing  
B.create a vivid image
C.show writing skills  
D.arouse people"s concern
2.In Paragraph 3 the writer mainly wants to tell us________.
A.the amount of consumed land
B.the neglected ecological impact
C.some familiar examples
D.some actual figures
3.Who may not like the idea of "recycling" pet animals?
A.Manufacturers.  
B.Drivers.
C.Animal fans.  
D.The authorities.
4.What do the authors think of living a sustainable life?
A.Challenging.  
B.Inspiring.
C.Inviting.  
D.Touching.

     The hippopotamus is, without doubt, one of the strangestlooking animals in the world.The ancient
Greeks named this large animal "hippopotamus, " which means "river horse." But hippos are not related
to horses.
     Found only in Africa, hippos come in two varieties.The small pygmy hippo lives in rain forests.And the
large common hippo lives mostly in grassland around rivers and lakes.
     The common hippo is the third largest land mammal in the world.It is lighter than the largest of the
white rhinos and the elephant, the heaviest land animal.The elephant is almost twice as heavy as the
common hippo.
      In the past, the hippo has been killed for meat, for sport, and for its tough skin.But today, in
preserves only, the common hippo has increased in number.The hippo has few predators(天敌) other
than lions and leopards that sometimes catch young hippos.There were many hippos killed by man during
the last half of the 19th century, when Africa was being explored and settled.And a great many hippos
and other animals were killed by poachers(偷猎者) during the fighting in Uganda in the 1970s.The hippo
is strong, though.It resists disease and has a long lifetime, living 20 to 40 years in the wild.
      Hippos spend most of their time in the water, only moving onto land at night to eat.By feeding at night, their skin is protected from the sun and the dry air that can cause a serious loss of moisture(水分).
      Because of its large body, the common hippo may appear awkward on land, but it can move very
fast and is considered by many to be the most dangerous animal in Africa.By spending their days in the
water and their nights on land, hippos make it difficult for scientists to study them, so there is still much to
be learned about hippos.The huge hippos, with their big mouths and tiny ears, have always fascinated
humans.As scientists learn more about them, they become even more fascinating.

1. We can learn from the passage that hippos ________.
A. have no connection with horses
B. can be found all over the world
C. are goodlooking animals
D. live mostly in rain forests

2. Which of the following may threaten the lives of hippos?
A. Rhinos.  
B. Water.
C. Lions.  
D. Elephants.

3. Why do hippos feed themselves at night?
A. It is cooler at night.
B. The air at night is fresher.
C. They try to avoid their predators.
D. The poachers don"t come out at night.

4. Why is it difficult for scientists to study the hippo?
A. It can move fast.
B. Its number is decreasing.
C. It is the most dangerous animal.
D. It doesn"t appear on land during the day.
