Both men and women are living longer these days in industrialized countries.1.In general, they can expect to live six or seven years more than men. One reason for this is biological.

One important biological factor that helps women live longer is the difference in hormones（荷爾蒙）between men and women.  2.Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

3.They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

4.Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman’s body cells have a tendency(傾向)to age more slowly then a man’s. Others think that a man’s body cells have a tendency to age more quickly. 5.

A. However, women, on average, live longer.

B .The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. Therefore, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control carious body functions.

The pupils of Grangetown High have been busy getting to know their newest and tallest classmate — a 7-meter-tall giraffe outside their school.

The giraffe is a huge sculpture (雕像) made by a local artist. The school's headmaster noticed the sculpture in the artist's garden as he drove past one day, and thought it would be perfect for his school. “I knew everyone would love it,” he said, “because our basketball team is known as the Grangetown Giraffes, and they wear giraffes on their shirts. So I asked them to write a letter to the artist, asking how much it would cost to buy the giraffe. He was very kind and got it ready to deliver (遞送) in six weeks — all for nothing! It was expected to arrive one Sunday morning, so that the pupils would see it when they got to school on Monday — at that time they had no idea that we were getting it.”

The artist, Tom Bennett, was a university professor (教授) of chemistry before he left that job in 2006 and only took up metalwork a couple of years ago. “I've always drawn pictures,” he said. “I can even remember doing it on my first day at school — I drew a horse. I wanted it to be the best horse picture ever, but I don't think I succeeded.” Tom's first metalwork was a bicycle for two that he and his wife could go cycling on together. “It was the most uncomfortable bike ever created,” he said, “so I gave up making bicycles and went into sculpture instead.”

Meanwhile the pupils at Grangetown High are very happy with their new classmate. “We're going to hold a competition to give it a proper name,” said one girl. “Everyone likes the expression on its face, so perhaps that will give us some ideas.”

1.According to the text, the giraffe _____.

A. was as tall as a basketball player

B. was given to Grangetown High for free

C. was sent to Grangetown High on Monday

D. was specially made for a basketball team

2.When the pupils got to school on Monday, they probably felt _____.

A. shy B. sad

C. excited D. confident

3.What can we learn about Tom Bennett?

A. He showed interest in art at an early age.

B. He was good at drawing, especially horses.

C. He visited Grangetown High as a professor.

D. He learned a lot about sculpture at university.

4.What's the main idea of the text?

A. It was a difficult job to name a giraffe.

B. Tom Bennett is well-known as a sculptor.

C. The Grangetown Giraffes is a strong team.

D. A metal giraffe arrived at Grangetown High.

I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn’t one of them. I can happily spend a whole day with a book, but my dad can’t read a book for longer than about 5 minutes. He reads emails, websites and documents for work, but not books. I think that siting down to read for just 15minutes a day is a good way to relax,So I introduce him to reading.Giving yourself a goal or challenge is a good way to change a habit or achieve something,so why not try to create a new habit of reading?

My dad is by no means the only person who avoids books. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests, but I think there are lots of benefits to reading, which screen-based activities don’t offer.

Firstly, it’s better for your eyes. Looking at screens can be very stressful for you eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night’s sleep.

One thing I personally love about reading, is being transported to another world—I often forget the time or things that are going on around me! Reading is a great way to switch off before you go to bed, because you think more about the world of the book, rather than the real world and the problems you have during the day, and you can truly relax. While watching a film,I often talk to my flatmates,send texts,or cut my nails,A book,on the other hand,commands your full attention.

So give it a go! Take 15 minutes to read every day,If you read a lot ,why not try 15 minutes at an English book, or pass the challenge on to someone else?

1.What is the real challenge for the author?

A. To read a book for 15minutes every day.

B. To read others how to read every day.

C. To read on what the best book is.

D. To get rid of his poor habit in a short time.

2.What can be concluded from the first paragraph about the author’s father?

A. He is often occupied with in his work.

B. He is a man with less education.

C. He is just for the sake of a comfort life.

D. He is too cowardly to face a challenge.

3.What can we know about the author from Paragraph4?

A. He usually treated his flatmates badly.

B. He had a special love for with books.

C. He wished to travel around the world.

D. He almost know nothing except books.

4.When it comes to reading books,_______.

A. only a few really knows the pleasure from books.

B. many devote their time to other things but books.

C. many people don’t think it is a thing worth doing.

D. some people read books far more than 15minutes.

At least once each winter I manage to get a good flight in the middle of a snowstorm. Last Sunday was that flight. My gliding(滑翔的) partners had looked at the weather reports of showers and decided to stay at home. People say that you shouldn’t fly by yourself, but on that day I felt the urge to go flying and so headed for my favorite gliding site.

I had the mountain ridge to myself. After a smooth lift-off, I floated stably in the breeze, feeling at peace with myself and the world. I looked across the valley to Bedford and a moment later saw the town disappear in a band of snow that was moving towards me.

The breeze remained strong enough for flying and I knew that as long as the visibility was good, it was OK for me to stay in the air. The snow moved in and swirled around me. It was a light dry snow. The day was already very quiet but, somehow, the light snow made it even more silent. I felt like a snowflake.

Two bald eagles joined me. They didn’t pay me any attention and spent a few minutes flying around the ridge before disappearing. I flew through another band of snow. I had been flying for about 45 minutes when I next looked across the valley. I could see there were more bands of snow to come and the breeze was dying too.

It was time to go home, get in a hot bath and warm up. I couldn’t wait to tell my gliding partners that they had missed out on a perfect flight.

1.Why did the author’s gliding partners refuse to fly on that day?

A. They preferred to fly alone

B. The weather did not permit

C. They did not like winter flights

D. The equipment was not adequate

2.Which is closest in meaning to the underlined word “” in Paragraph 3?

A. Weather

B. Skill

C. Possibility

D. View

3.What can be inferred from the passage?

A. The bald eagle can cause damage to the author’s flight

B. The author will land and go home after the snow stops

C. Brand of snow will be a great threat to the author’s flight

D. The author will hesitate to share his experience with his partners

4.What could be the best title for the article?

A. The First Flight Alone

B. A Narrow-Escape Flight

C. One Never-Again Flight

D. An Impressive Winter Flight
