【題目】We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer.

Recently, researchers studied more than 55,000 adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average, three years longer than the non-runners.

Running may be good exercise, but it can be difficult on the body. Here are commonly shared ideas among fitness experts(健身專家) to lower the risk of injury(受傷) for people who are new to running.

Take it easy.

Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance(里程) or speed.

Get good running shoes.

There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometers.

Take good notes.

Take time after each run to write down notes about what you did and how you felt. Look for things that happen again and again. For example, you may find that your knees hurt when you run sometimes. But perhaps you feel great when you have a rest between running days. These notes will help you make the best plan for running.

【1】The writer wants to tell us in the first paragraph ____________.

A. good health comes from running

B. running is the best exercise

C. health problem can be solved by good exercise

D. not all exercise is equally good

A. a good habit of running may help you live longer

B. the number of non-runners was getting smaller

C. three quarters of 55,000 adults were new to running

D. the hope to live three years longer drives people to exercise

【3】Increases in distance or speed depend on ____________.

A. what the fitness experts say

B. whether you have the best shoes

C. how your body feels

D. why you start running

【4】The purpose of taking notes is to ____________.

A. remind you of where to have new shoes

B. help you find the way of running that fits you

C. take a rest between running days

D. help you do some research on exercise

【題目】閱讀表達(dá)。 To me, music is food and water. I can't live without it. I know this is not true for everybody. Usually lots of people go to concerts or listen to music records. Maybe some of you don't do these and you get along quite well, but music is everywhere in our life. For example, when you see movies or watch TV plays, will you find them interesting if there is no music? I'm sure you will find them boring. And when you are waiting for the train or the plane, you would like some music because it makes the time seem shorter.
Some people like to sit by the sea and listen to the sound of the sea. Some enjoy listening to the singing of birds. Those sounds are some kind of music. So music has a meaning for everyone to some extent. （程度） Of course, it has special meaning for people like me. We spend our lives playing or writing music.
Someone said," Through music a child goes into a world of beauty, learn to take care of others and makes his mind and body healthy." Music is really an important part of our life.
（1）根據(jù)課文內(nèi)容判斷正誤。People may think the movies or TV plays boring without music.
（2）What is music to the writer?
（3）How do lots of people enjoy music?
（4）將文章中劃線句子翻譯成漢語。
（5）for example 的漢語意思

【題目】根據(jù)短文內(nèi)容理解，選擇正確答案。 Why do plants grow in some places but not in others? Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all?
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why there are almost no trees or grass in dry deserts.
Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built(被建立) on hard land. The plants there have only the soil between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach? A few plants, such as grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.
（1）According to the passage, plants need _______ things to grow well.
A.two
B.three
C.four
D.five
（2）The underlined word "cracks" means "________".
A.long narrow opening
B.the surface of something
C.small plants on something
D.the bottom of something

With such a large rise on mobile phone users around the world over the last 10 years,many people are worried about__【1】__ possible problems.For some time,scientists have been thinking that mobile phones could lead to cancer.But so far,there is no strong evidence （證據(jù)）for this.

The Norway Institute of Public Health and the UK 's Health Protection Agency both released some studies last year.They said that there was no link found between mobile phone radiation(輻射) and cancer.

However,many mobile phone users often __【2】__headaches, dizziness （頭暈）and even feeling sick.Last October,a court case （訴訟案件）in Italy said that heavy mobile phone usage had caused brain cancer in one man.He had used a mobile phone up to six hours a day for 12 years. But the biggest problem with research now is that it is too early to reach conclusions.Mobile phones have only been__【3】__ used since the 1990s,and cancers can take many years to develop. There is also still a strong argument that mobile phones are a major risk for children."Inner child,small central brain structures are going to be exposed（暴露）,"said Dr.Annie,"Besides,kids have a skell（頭蓋骨） which is_【4】__.There is much more water in their brain,so there are many reasons that they take in more of the same radiation."

Although we still don't know whether using mobile phones can cause cancer,we should try to use our phones__【5】__.Here are some tips:*Use a headset（耳機(jī)） or speaker.

Headsets give out much less radiation than phones.Some wireless headsets give out low-level radiation.However,you should _【6】__your headset when you're not talking to anyone.Using a phone with a speaker will also make it safer. *Listen more, talk less.Your phone gives out radiation when you talk or text,but not when you're listening or getting messages.

*Hold the phone away from your body when you are talking,not _【7】__your ear.

Also,don't keep it in your pocket.

*Choosing texting over talking.Phones give out less radiation when sending texts than when making calls.Texting also keeps radiation away from your head.

*Poor signal?Stay off the phone.Fewer signal bars（信號格數(shù)） on your phone _【8】__that the phone needs to give out more radiation to work.Make and take calls when your phone has a strong signal.
