题目内容

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 go through a machine. The machine cooled the blood. Then the machine sent the 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

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 operation?

Eating a diet high in processed（加工） food increases the risk of depression（抑郁）, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food，which includes lots of fruit, vegetables and fish，and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat，refined（精制的） grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood（全天然食物） had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.（解释原因） He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.
Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy. The UK population is consuming （消费）less nutritious, fresh produce and more saturated（饱和） fats and sugars.

In 2030, 42 percent of American adults will be obese, and about one-quarter of that group will be severely obese, a condition that shortens life and wastes large medical expenses, a new study predicts.
Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.
小题1:The word “ailments” in the second paragraph is equal to _______.

You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place. “They” did things to you which caused all of your pain and suffering. “They” are wrong and bad, and life is terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing(内化)your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.
Those who choose to be creators look at life quite differently. They know there are individuals who might like to control their lives, but they don’t let this get in the way. They know they have their weaknesses, yet they don’t blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred(神圣的)moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺)in anger, guilt, and other emotions that cause others---and even themselves---to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of their lives.
In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.
小题1:What does the word “they” in Paragraph 1 probably refer to?

A．People and things around you.	B．Opportunities and problems.
C．Creators and their choices.	D．Victims and their sufferings.

小题2:According to Paragraph 2, creators __________.

A．seem willing to experience failures in life

B．possess the ability to predict future life

C．handle ups and downs of life wisely

D．have potential to create something new

小题3:What can we learn from Paragraph 3?

A．Creators and victims face quite different things in life.

B．Creators and victims are masters of their lives.

C．Victims can influence more people than creators.

D．Compared with victims, creators are more emotional.

小题4:The examples mentioned in Paragraph 4 show that _______________.

A．strong attachment to sufferings in life pulls people into victims.

B．people need family support to deal with challengers in life.

C．it takes creators quite a long time to get rid of their pains.

D．one’s experiences determine his attitude toward life.

小题5:What is the author’s purpose in writing this passage?

A．To define victims and creators.

B．To evaluate victims against creators.

Forget chip fat, sugar cane or rapeseed oil — the latest source of biofuel could be watermelons. Scientists have discovered that the fruit is a great source of sugar that can be readily distilled (蒸馏) into alcohol to power cars and farm machinery.
And sellers reject 360,000 tons of “substandard” fruit every year in America alone which could be used as an economical way to make fuel. The waste from US growers could produce nearly two million gallons (nine million litres) of biofuel per year.
In the study, researchers at the United States Department of Agriculture set out to determine the biofuel potential of juice from rejected watermelons —those not sold due to cosmetic imperfections, and currently ploughed back into the field. About a fifth of each yearly watermelon crop is left in the field because of surface blemishes (瑕疵) or because they are misshapen.
Dr. Wayne Fish, who led the team, found that 50 percent of the fruit was fermentable (可发酵的) into alcohol which could provide valuable fuel.
“We’ve shown that the juice of these watermelons is a source of readily fermentable sugars, representing an unexploited raw material for alcohol biofuel production,” he said.
The study, published in the journal Biotechnology for Biofuels, discovered that watermelons could produce around 20 gallons of fuel per acre from fruit that otherwise would go to waste.
Production of biofuels has been targeted by Western governments as a way to support renewable energy targets.
The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met.
The British government’s Renewable Transport Fuel Obligation requires five percent of the fuel sold at the pump by 2010 to be biofuel.
小题1:The passage mainly tells us ______.

A．watermelon juice will be the largest source of renewable energy

B．the advantages of fuel made from watermelons

C．Western countries aim at producing biofuels

D．watermelons could be used to make fuel

小题2: It can be learned from the text that ______.

A．about two gallons of fuel could be made from rejected fruit per acre

C．half of the watermelons were fermentable into alcohol to provide energy

D．five percent of fuel is required to be biofuel from watermelons by 2010 in Britain

小题3:The underlined word “cosmetic” in Paragraph 3 probably means ______.

小题4:We can infer from the passage that ______.

A．it will cost a lot to make biofuel from watermelons

B．Western countries are engaged in biofuel study but still have a long way to go

C．watermelon juice has been used as a source of sugars to produce alcohol biofuel

D．the European Union is likely to meet its target of transport fuels from biological sources

Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment（营养）. The old saying “An apple a day keeps the doctor away. ” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form(丸剂), believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins, so why waste money on them?
In the modern western world, many people are too busy to bother about eating properly. They throw away the good habits and throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening.
小题1:From the first sentence we know that ________

A．all kinds of food you eat can be made into nourishment

B．your body is make up of the food you eat

C．what you eat has great effect on your health

D．the more you eat, the better you will feel

B．Doctors are no longer necessary if we eat an apple every day.

C．The apple is the best among all kinds of fruits.

D．An apple is a good way to cure illnesses.

小题3: What can we conclude from the second paragraph?

A．Our bodies need food, or we can’t live.

B．Often eating apples is a good habit.

C．Taking extra vitamin pills is completely useless.

D．A good diet is of great importance for our health.

小题4:In modern western countries, ________.

A．people don’t want to pay more attention to their eating

D．throw everything into our stomachs slowly and carefully

Coffee is one of the world's most widely-enjoyed drinks. Now, a new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.
Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn't really have any expectation of which direction it could go into."
To sort out the confusion, Hashibe and her assistants used statistical (统计学 ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained, "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. '
Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day."
Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention.
Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants （抗氧化物）in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers."
小题1:This passage is probably taken from __

A．a literature book	B．a travel journal
C．an old directory	D．a medical magazine

小题2:Dr. Hashibe expected nothing of her research because __

A．it was impossible to get the desired result	B．the research was much surprising in fact
C．no conclusions had been reached before	D．the research team lacked faith in success

小题3:Which of the following might have something to do with the protection against mouth cancer?

A．Coffee without chemicals.	B．Coffee without caffeine.
C．Four cups of tea a day.	D．Antioxidants in coffee.

小题4:What do we know about Dr. Mia Hashibe and her research?

A．She knew for sure how coffee may affect drinkers.

B．She included 4,000 people without cancer in study.

C．She found an effect for three cups of coffee a day.

D．She based her research on several earlier studies.

小题5:What would be the best title for the text?

A．Drinking Coffee May Protect Some Cancers	B．Drinking Coffee May Prevent Some Cancers
C．Drinking Coffee May Cure Some Caneers	D．Drinking Coffee May Cause Some Cancers
