It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
小题1:.The biggest difficulty in operating on the damaged brain is that ____.
A．the time is too short for doctors
B．the patients are often too nervous
C．the damage is extremely hard to fix
D．the blood-cooling machine might break down
小题2:.The brain operation was made possible mainly by ____.
A．taking the blood out of the brain
B．trying the operation on monkeys first
C．having the blood go through a machine
D．lowering the brain’s temperature
小题3:.With Dr. White’s new idea, the operation on the damaged brain ____.
A．can last as long as 30 minutes
B．can keep the brain’s blood warm
C．can keep the patient’s brain healthy
D．can help monkeys do different jobs
小题4:. What is the right order of the steps in the operations?
a. send the cooled back to the brain      b. stop the blood to the brain
c. have the blood cooled down          d. operate on the brain

In many societies, there is often greater acceptance of light skin than dark skin. Light skin may be seen as a mark of beauty, intelligence and success. These beliefs can lead to social pressures even within the same racial or ethnic group, if some members are darker skinned than others.
The result is that skin lightening has become a common activity across Africa, Asia and other areas of the world. More and more people with dark skin are using skin-lightening products, even if it means they may face health risks.
They believe that having whiter skin will improve their lives. Many people think they will have a better chance of getting a job or marrying into a better family. Or they want to look like what their society generally considers beautiful.
Some beauty care products and soaps contain chemicals that make skin lighter. This is also called bleaching. But some of the chemicals are extremely dangerous. One of the most dangerous is hydroquinone(对苯二酚).
Hydroquinone has been banned in several countries. This chemical has been connected to kidney damage and some kinds of cancer. It also causes low birth weight in babies when mothers –to-be use it during pregnancy.
At first, bleaching products make the skin color lighter. But after long-term use they can cause problems. They could even make some skin darker.
The chemicals in the products block and break down the natural process that gives color to skin. The skin loses its natural barrier（障碍）to protect against sunlight. Then the skin can become thick and discolored. Usually the person will use more of the product in an effort to correct the problem, but this only makes it worse.
Fatimata Ly treats skin conditions in the Senegalese capital, Dakar. Doctor Ly says skin bleaching has become a problem throughout Senegal. She says the chemicals are now more dangerous because they are stronger. Some cases have resulted in blackened fingernails, infections and permanent（永久的）skin damage.
And these are not the only risks. Experts say some people who change their skin color suffer emotional damage. They feel regret and sadness. They feel that instead of risking their health, they should have learned to love and accept their skin color as it was.
小题1:What is the text mainly about?
A．The advantages of light skinB．Introducing skin lightening products
C．The harmfulness of HydroquinoneD．The health risks of bleaching
小题2:What does the underlined word “bleaching” refer to?
A．The process of removing the color
B．The process of making the skin whiter
C．The chemicals that make things white
D．The chemicals that protect skin against sunlight
小题3:Why do people want to make their skin lighter?
A．Because they all want to look more beautiful.
B．Because they all want to marry into better families.
C．Because they want to find better jobs.
D．Because they want to improve their lives.
小题4:Skin bleaching may cause the problem of ______.
A．emotional problems B．kidney cancerC．lighter skin D．low birth rate
小题5:The author holds a/ an ______ attitude towards skin lightening.

A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （补充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿病）. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.
小题1:The underlined word “obese” in the first paragraph may mean       .
A．quite protective B．very sad
C．very fatD．quite young
小题2:According to Chinese researchers, if a person who lacks sleep can get more sleep during weekends,       .
A．he won’t get hungry easilyB．he will feel tired all the time
C．there will be little chance of him becoming fat
D．it will be very hard for him to fall asleep at night
小题3:From the passage we know       .
A．too little sleep will result in illness besides obesity
B．in the past people didn’t connect sleep with weight
C．fat children must have slept less than 10 hours five years ago
D．most children are unhealthy because of little sleep

Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom. Although many people have passed away for having smoked a lot and we call on people to give up smoking, yet many more that are following will turn down what we say every day, above all, the young people smoke a lot more.

Boiler rooms are often dirty and steamy, but this one is clean and cool. Fox Point is a very new 47-unit living building in South Bronx, one of the city’s poorest areas. Two-thirds of the people living there are formerly (以前) homeless people, whose rent is paid by the government. The rest are low-income families. The boiler room has special equipment, which produces energy for electricity and heat. It reuses heat that would otherwise be lost to the air, reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladia, a group that specializes in providing housing and services to needy people. Palladia received support from Enterprise Community Partners (ECP), which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (环境方面) clever and affordable homes which are called, the Green Communities Standards. These standards include water keeping, energy saving and the use of environmentally friendly building materials. Meeting the standards increases housing construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a window to get most daylight can help save energy.
Michael. Bloomberg, New York's mayor plans to create 165,000 affordable housing units for 500,000 New Yorkers. Almost 80% of New York City’s greenhouse-gas emissions come from buildings, and 40% of those are caused by housing. So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD) , whose duty is to develop and keep the city’s supply of affordable housing, will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York’s DHPD is the largest city developer of affordable housing in the country.

A． New York City is seriously polluted
B． people’s daily life causes many carbon emissions in New York City
C． a great number of people in New York City don't have houses to live in

Recently the World Health Organization announced that the disease of
smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward
Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox began to disappear.
71．Vaccination against smallpox has been so successful that _________ .
A．the discoverer made a large amount of money
B．Dr Jenner was given a prize by the World Health Organization

A．most people were vaccinated against the disease at least once
B．people going abroad should promise not to spread the disease
C．people travelling from one country to another must prove they are vaccinated
D．people must be vaccinated shortly before going to foreign countries
73 ．What led Dr Jenner to experiment with vaccination was that ________ .　
A．he wanted to make a great discovery and publish it
B．vaccination could make people's arms safe
C．he tried to cure the farmers of some disease caught from the cattle
D．those who worked with cattle seemed free from getting smallpox
74．The doctor's new discovery was called ‘vaccination’ for the reason that ________ .
A．he discovered smallpox near a farm
B．he experimented with a disease from the cattle
C．he was working with cattle in the countryside
D．people got the disease of smallpox from the cattle
75．The news of the discovery ________.
A．caught people's attention from all corners of the world
B．spread far and near in the western countries
C．made people rush to Dr Jenner for vaccination
D．helped to get rid of the terrible disease of smallpox
There's a lot of discussion these days about healthy kids. People who care (parents, doctors, teachers, and others) want to know how to help kids be more healthy.
Being healthy is a way of saying a person eats well, gets a lot of physical activity (exercise), and has a healthy weight. If you're healthy, your body works well, feels good, and can do all the things you want to do. Here are five rules to live by, if you're a kid who wants to be healthy.
Eat a Variety of Foods, Especially Fruits and Vegetables. You may have a favorite food, but the best choice is to eat a variety. If you eat different foods, you're more likely to get the nutrients(营养) your body needs. Taste new foods and old ones you haven't tried for a while. Get at least five servings of fruits and vegetables a day — two fruits and three vegetables.
Drink Water and Milk Most Often. When you're really thirsty, cold water is the No. 1 for you. Kids need calcium（钙）to build strong bones, and milk is a great source of this mineral. How much do kids need? Aim for 3 cups of milk per day. You can mix it up by having milk and some other calcium-rich dairy foods .
Be Active.One job you have as a kid — and it's a fun one — is that you get to figure out which activities you like best. Not everyone loves baseball or soccer. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day. You might even write down a list of fun stuff to do, so you can refer to it when your mom or dad says it's time to stop watching TV or playing computer games!
小题1: What’s the best title for this passage?
A．Do Your Favorite Activities RegularlyB．Eat More Fruits and Vegetables Every Day
C．Drink Water and Milk When You Are ThirstyD．Tips on How to Keep Healthy
