Scientists have shown that eggs produce proteins with a function similar to that of powerful blood
pressurelowering drugs.
The researchers, from the University of Alberta in Canada, showed that when eggs come in contact
with stomach enzymes (酶) they produce a protein that acts in the same way as ACE inhibitors, drugs
taken by millions around the world to lower blood pressure.Fried eggs proved particularly effective, but
more work is needed to show the effects outside a lab and in the human body.
Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to
work on an egg.They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on
increasing heart disease risks.
Researcher Professor Bruce Griffin, from the University of Surrey, said, "The wrong beliefs linking
egg eating to high blood cholesterol and heart disease must be corrected.The amount of fat in our diet
has an effect on blood cholesterol that is several times greater than the relatively small amount of
cholesterol found in eggs.The UK public do not need to limit the number of eggs they eat.They can be
encouraged to include them in a healthy diet as they are one of nature"s most nutritious foods."
The British Heart Foundation dropped its threeeggaweek limit in 2005.However, almost half of
Britons believe the limit still applies.
1. From the text we know that ACE inhibitors are________.
A. a kind of medicine
B. a kind of protein
C. a kind of illness
D. a kind of food
2. According to what Professor Bruce said, eggs________.
A. are the most nutritious food
B. have no effect on blood cholesterol
C. can be included in a healthy diet
D. are forbidden to be eaten in the UK
3. We can infer from the text that________.
A. drugs to lower blood pressure will be replaced by eating eggs
B. stomach enzymes mixed with eggs can cure heart diseases
C. most Britons agree the threeeggaweek limit should be dropped
D. about 50% of Britons think eating an egg a day is bad for their health
4. The text is meant________.
A. to introduce scientific findings about eggs
B. to introduce a medicine made from eggs
C. to tell people how to lower their blood pressure
D. to advise people to eat as many eggs as possible

call your teacher or your classmate and ask about homework. It is your responsibility(责任)to find out
what homework you have missed. It is not the teacher"s job to remind you of the missed assignments.
You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will
not be there for the test. If your teacher allows a make-up test(补考),you should take the test within one
or two days after you return to class. Serious illness is the only reason for missing a test.
Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure
to do it quietly. Have your books and papers out of your bag before you come into the room. Then go
to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the
classroom. Most teachers will give you a low grade if you are often late.
In America, you should call your teacher by his or her last name instead of " teacher". Also you
should use Mr, Miss, Ms or Mrs before the last name ( such as Mrs Smith or Mr Jones). This is polite.
The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum
during class. Don"t do these until the break. Also, removing your shoes in the classroom is not polite.
1. What should you do if you miss a class?
A. Give an excuse for missing the assignments.
B. Tell the teacher you can"t come to school or do the assignments.
C. Ask your teacher to remind you of the missed assignments.
D. Call your teacher or your classmate to find out what assignments were given.
2. When can a student miss a test according to the passage?
A. When he / she is late for the test.
B. When he/ she is really sick.
C. When he / she failed another test.
D. When he / she doesn"t want to have the test.
3. In America, if your teacher"s name is Susan Black, what should you call her politely?
A. Ms Black
B. Ms Susan
C. Susan Black
D. Teacher Black
4. Which of the following is NOT true according to the passage?
A. A student is thought to be impolite when he / she takes off his / her shoes in the classroom.
B. A student is thought to be impolite when he / she eats and drinks in class.
C. When a student is late for class, he / she must knock before he / she enters the classroom.
D. A student is thought to be impolite when he/she doesn"t come for class on time.
through the body. For the past seven years, Simon Thorrold, a university professor, has been examining
fish ears, small round ear bones called otoliths.
As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate (碳酸钙).
By looking through a microscope (显微镜) and counting (数) these rings, Thorrold can determine the
exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly
rings, which can also be counted, giving information about the fish"s age, just like the growth rings of a
tree.
Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They"re
examining the chemical elements (元素) of each otolith ring.
The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on
any given day. These elements tell us about the chemistry of the water that the fish was in. It also says
something about water temperature, which determines how much of these elements will gather within
each otolith ring.
Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water
of coastal areas. He can basically tell where fish are spending their time at any given stage of history.
In the case of the Atlantic croaker, a popular saltwater food
fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many
hundreds of miles.
This is important to managers in the fish industry, who know nearly nothing about the whereabouts (行踪) of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists
are now lending Thorrold their ears.
1. What can we learn about fish ears from the text?
A. They are small soft rings.
B. They are not seen from the outside.
C. They are openings only on food fish.
D. They are not used to receive sound.
2. Why does the writer compare the fish to trees?
A. Trees gain a growth ring each day.
B. Trees also have otoliths.
C. Their growth rings are very small.
D. They both have growth rings.
3. Why is it important to study the chemistry of otolith rings?
A. The elements of the otoliths can tell the history of the sea.
B. Chemical contents (含量) of otoliths can tell how fast fish can swim.
C. We can know more about fish and their living environment.
D. Scientists can know exactly how old a fish is.
4. How would you understand
"fish scientists are now lending their ears"? A. They are very interested in Thorrold"s research findings.
B. They want to know where they can find fish.
C. They lend their fish for chemical studies.
D. They wonder if Thorrold can find growth rings from their ears.
Falling leaves, whithering flowers, sold winds, faint sunshine. 1 Spirits can be low.
People who suffer from " the autumn blues" often are extremely exhausted , lack energy, need more
sleep, feel increased appetite and gain weight.
" The exact cause of this condition, often called seasonal depression or seasonal affective disorder
(SAD), is not known yet," says Chen Jue, associate professor at Shanghai Mental Health Center. " But
recent studies indicate that weather change is influential and strongly suggest that this condition is caused
by changes in the availability of sunlight."
One theory is that with decreased exposure to sunlight, the biological clock that regulates mood,
sleep, and hormones is delayed, running more slowly in winter. 2 Another theory is that brain chemicals
that transmit information between nerves may be altered(改变) in individuals with SAD. It is believed
that exposure to light can correct these imbalances.
" 3 Remember, spring always lives in your heart," Chen says.
Here are some tips to deal with autumn depression.
1.Go outdoors and get some sunlight. More around. Fresh air and exercise improve the respiratory( 呼
吸) system and blood circulation and regulate the nerves system. Thus , exercise is calming and relieves
one"s mood.
2.Relax at work. Stretch, breathe deeply. Take a tea break. Think of your next vacation.
3. 4 Chocolate and sugar raise the spirits.
4. Look at bright colors, such as red and orange.
5. 5 Blooming plants are cheering
6.Call friends or family when you feel lonely or depressed. Recall some happy memories.
A. Exposure
to light may reset the biological clock.B. Decorate your room and work space with flowers
C. It is a sad season, but you can try to make it happy.
D.That is the way you can use to lighten yourself.
E. Keep a chocolate bar in your pocket.
F. For many people ,late autumn can be a season of gloom and depression. Autumn always gives
us a beautiful scene.
something for your local environment? As early as next year it may well be possible. When you have
finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to
flower.
A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped
that the new type of phone will encourage consumers to recycle (再利用). Scientists have come up with
a new material over the last five years. It looks like any other plastic, but overtime it can break down into
the soil without giving out any poisonous chemicals. British researchers used the new material to develop
a phone cover that contains a sunflower seed. When this cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow. "We"ve only put sunflower seeds into the cover so far.
But we are working with plant experts to find out which flowers will perform best. Maybe we could put
roses in next time." said one scientist.
As phone technology is developing so quickly people are constantly throwing their mobiles away. This
means producers are under pressure to find ways of recycling them. Some 650 million mobile phones
have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal
and chemical waste to the environment. A biodegradable cover can offer some relief for nature,
according to the scientists. "The seed is released and the flower grows in the pot so you don"t have to
concern yourself with the phone when you have finished using it," said Kerry Kirwan, the leader of the
research team.
1. After you have finished using the new type of mobile phone, _______.
A. the sunflower seed will come out and flower in the pot
B. the phone cover will break down very soon in the soil
C. it will be recycled by the producers
D. it can charge itself with electricity in a green way
2. This type of research is done because ________.
A. the technology of making phones is changing rapidly
B. too many waste mobile phones may lead to environmental problems
C. nobody has ever thought of recycling mobile phones
D. producing mobile phones uses a lot of energy
3. We can infer from the story ________.
A. the new type of mobile phones is already on the market
B. the new type of mobile phones will sell extremely well
C. the material of the new type of phones is
harmfulD. other flowers may be used in the new type of mobile phones
have never practiced ever since. A man who has not had a chance to go swimming for years can still
swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still
ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the
words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember
the story of Cinderella or Goldilocks and the Three Bears.
One explanation is the law of overlearning, which can be stated as follows: Once we have learned
something, additional learning trials increase the length of time we will Remember it
In childhood we usually continue to practice such skills as swimming, bicycle riding, and
playing baseball long after we have learned them. We continue to listen to and remind
ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as
Cinderella and Goldilocks. We not only learn but overlearn.
The multiplication tables(乘法口诀表)are an exception to the general rule. that we
forget rather quickly the things that we learn in school, because they are another of the things
we overlearn in childhood.
The law of overleatning explains why crammingJ(突击学习)for an examination, though
it may result in a passing grade, is not a satisfactory way to learn a college course. By
cramming, a student may learn the subject well enough to get by on the examination, but he is
likely soon to forget almost everything he learned. A little overlearning, on the other hand, is
really necessary for one"s future development.
B. Children have a better memory than grown-ups.
C. Poem reading is a good way to learn words."
D. Stories for children are easy to remember.
B. setting down general rules
C. making a comparison
D. using examples
B. a special case of cramming
C. a skill to deal with math problems
D. a basic step towards advanced studies
B. It"s helpful only in a limited way.
C. It"s possible to result in poor memory.
D. It increases students" learning interest.
