Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中風(fēng))within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
1.The text mainly discusses the relationship between ______ .
A. heart problems and air quality
B. heart problems and exercising
C. heart problems and smoking
D. heart problems and fatty food
2.The underlined word “modest” in Paragraph 3 most probably means ______ .
A. relatively high B. extremely low
C. relatively low D. extremely high
3.The author’s purpose of writing the text is most likely to _______.
A.describe B. persuade C. inform D. entertain

Not everyone is good at remembering names. 1. What’s worse is that someone else is with you and you know you’ll have to introduce the two of them to each other. Here are some strategies that may help you remember names easily.
Listen attentively.2.Listen attentively to the name and concentrate on the face. Don’t look at the person’s clothes or her jewelry (首飾). If you did not hear the name clearly, ask the name to be repeated.
Find connections. The person you are introduced to may be a doctor, a mother of five or a cancer survivor. 3.The details may come out during your conversation or another person may provide them at a later time.
Repeat the name. 4. If the conversation is short, once should be enough. For a longer conversation, you can repeat her name two or three times, but never use her name in every sentence.
Refer the name to another person. You can tell a friend or a family member that you met, for example, Anna Smith at a party. Describe a little about Anna. 5. However, this is an exercise for you to remember the person’s name.
A. Write down the name when necessary.
B. You’d better connect the details about the person to her name.
C. Of course your friend may not care so much for this information.
D. Pronounce and spell the name so that you can remember it.
E. Whenever you are introduced to someone, keep your mind on it.
F. During the course of your conversation with anyone new to you, use her name once in a while.
G. You may have been in situations where you see a familiar face but you just can’t remember her name.

Let us suppose it is now about A.D. 2060. Let's make believe it is about 47 years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old.
What are people eating now? People are still eating food. They haven't yet started to take on heir(繼承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet's surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
We are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.
Such would be our life in 2060.
1.When was the passage written?
A. In about A.D. 2060 B. In about 1960
C. In about 2013 D. In about 2014

There are many wetlands in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve(麋鹿自然保護(hù)區(qū)) is in them. More than 700 Milu deer live freely there. There are not many red-crowned cranes(丹頂鶴)in the world, but every winter you can see some in the Red-crown Cranes Nature Reserve in the Yellow Sea Wetlands.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for the wildlife.
Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.
1.The Yellow Sea Wetlands are in the ________ part of China.
A. Northeast B. northwest
C. southeast D. southwest
2.What is the weather usually like in the wetlands?
A. Hot B. Dry C. Cold D. Mild

A. On June 25th. B. On April 22nd.

Still seeking a destination for your weekend break? There are some places which are probably a mere wall away from your college.
King’s Art Centre
A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.
You could attend a class teaching you how to ‘learn from the masters’ or get more creative with paint – free of charge.
The Centre also runs two life drawing classes for which there is a small fee.
The Botanic Garden
The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.
The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.
Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.
The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid’ is regularly seen lying in the heat of the warm sun.
Byron’s Pool
Many stories surround Lord Byron’s time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of “mess and drunkenness”. However, it seems as though Byron did manage to pass the time pleasantly enough. I’m not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village.
It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron’s Pool. A couple of miles past Grant Chester in the south Cambridge shire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don’t trust me, then perhaps you’ll take it from Virginia Woolf – over a century after Byron, she reportedly took a trip to swim in the same pool.
1.As mentioned in the passage, there is a small charge for ____.
A. attending the masters’ class
B. working with local artists
C. learning life drawing
D. seeing an exhibition
2.“Torch Aloe” and “Venus Flytrap” are ____.
A. common insects
B. impressive plants
C. rarely-seen snakes
D. wildlife-enthusiasts
3.We can infer from the passage that Byron seemed ____.
A. to fear pet bears
B. to like walking
C. to be a heavy drinker
D. to finish university in 1805
4. In the passage Byron’s Pool is described as a lake ____.
A. surrounded by fields
B. owned by Lord Byron
C. located in Grant Chester
D. discovered by Virginia Woolf

It was raining hardly outside, that made it difficult for me to go home for lunch. Just as I was wondering what I should eat at noon, I saw a familiar figure passed by our classroom. I rushed out and it was my mother, who is already in the fifties, that brought me lunch, in spite the heavy rain. In China, many parents make great sacrifices for our children. But what had the children done in return?All too often, most children just take it for granted that their parents should serve for them unconditionally. My dear mum or dad, thank you very much for bringing me up. How shall I do for you?

As we know, when senior students finish their school, most of their reference books are thrown away, which are still in good condition. How a great waste it is!
I suggest that students must recycle all these books. On the one hand, recycling them can save a lot of natural resource, which are used to make textbooks. On the other hand, the notes in the books are helpful to whoever need them.
In fact, recycling textbooks has been increasing popular in such countries like America and Australia. We should learn from them, but make every effort to build energy-saving society. In my opinion, it is of much benefit from our present and our future.
