题目内容

It’s lucky for young athletes all over the world to get their chance at Olympic gold since the International Olympic Committee(IOC) voted unanimously (一致地) to host the Young Olympics.

The first-ever Summer Youth Olympics made their debut(首次亮相) in August of 2010. The 12-day competition featured 3,200 kids between the ages of 14 and 18. The first Winter Youth Olympics will be held in 2012 and are expected to attract 1,000 athletes. Both Games will take place every four years on a regular basis.

Childhood obesity was listed as one of the reasons for launching the Young Olympics, IOC president Jacques Rogge said he hoped the global competitions would inspire young people to get off the couch and get into shape.

Rogge also admitted that the IOC wished to attract a younger television audience to the formal Olympics. In the past years, interest in the Games among young people has decreased, with the average age of Olympic viewers on the rise.

Rogge agreed that kids today are more interested in such competitions as the X Games, which features such sports as BMX freestyle, surfing on the sea and Moto X Racing.

The Olympics have tried to keep up with the competition by adding BMX-crossing cycling(自行车越野赛), ski cross and snowboarding to the Olympic program. And the IOC is hoping to strengthen its reputation among teens by including skateboarding in the 2012 London Olympics.

56. The International Olympic Committee decided to start the Youth Olympics in order to____.

A. encourage young people to exercise more

B. stress the importance of the Olympics

C. develop student’s sense of competition

D. pull in an older audience to the Olympics

A. How long the Winter Youth Olympics will last.

B. When the Winter Youth Olympics will be held.

　　Rapidly warming climate is likely to seriously change crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world's population facing serious food shortages, according to a study to be published on Friday in Science Magazine．

　　The population of this equatorial(赤道的)belt is among the poorest on Earth and is growing faster than anywhere else, the study said．

　　''The stresses on global food production from temperature alone are going to be huge, and that doesn't take into account water supplies stressed by the higher temperatures,” David Battisti, lead author of the study, said．

　　Battisti, a professor at the University of Washington, cooperated with Rosamond Naylor, director of Stanford University's Program on Food Security and the Environment, to examine the influence of climate change on the world's food security．

　　By combining direct observations with data from 23 global climate models that contributed to a Nobel Prize－winning research in 2007, Battisti and Naylor determined that there is greater than a 90 percent probability that by 2100 the lowest growing-season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date．

　　In the tropics, the higher temperatures can be expected to cut yields of the primary food crops, maize(玉米)and rice by 20 to 40 percent, the researchers said．

　　The serious climate issues will not be limited to the tropics, the scientists conclude．As an example, they cite record temperatures that struck Western Europe in June, July and August of 2003．The summer-long heat wave in France and Italy cut wheat yields and fodder(饲料)production by one-third．

(1)

The direct result of the rapidly warming climate will be ________．
[　　]
A．	food shortages
B．	the change of weather
C．	a drop of crop yields
D．	fast rising of sea water

(2)

According to David Battisti, ________．
[　　]
A．	the temperature change is the only stress on global food production
B．	both the temperature change and the lack of water supplies are big problems
C．	water supplies stressed by the higher temperatures are even more serious
D．	it's lucky that water supplies haven't been stressed yet at present

(3)

Paragraph 5 tells us the following information EXCEPT that ________．
[　　]
A．	Battisti and Naylor were the Nobel Prize winners in 2007
B．	the result comes from the direct observations and data from 23 global climate models
C．	data from 23 global climate models was a great help to Battisti and Naylor's research
D．	the temperature in the tropics and subtropics will last till 2100

(4)

The underlined phrase “to date” probably means“________”．
[　　]
A．	so far
B．	in history
C．	up to then
D．	at any time

(5)

We can infer from the text that ________．
[　　]
A．	the serious climate issues will influence any place of the world
B．	Western Europe will suffer the most in crop yields
C．	half of the population of the world will starve to death by 2100
D．	warming climate will not affect other places except the tropics and Europe

If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?

As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.

That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.

We can hardly find black flowers because _____.

A. they are so weak that it’s difficult for them to grow up

B. there are no black flowers in the world.

C. the petals of black flowers are very delicate

D. they can take in the light of all wave lengths, which make the flowers dry up

Sunlight is formed by _____.

A. many different kinds of coloured light

B. three different kinds of coloured light—red, orange and yellow

C. seven different kinds of coloured light

D. four thousand kinds of coloured light

The red, orange or yellow light contains _____.

A. less heat than the other lights B. more heat than the other lights

C. a great deal of heat D. a little heat

“It is a chance in a million” means_____________

A. it is common B. it is extremely rare C. it’s lucky D. it’s impossible

9 Lansdowne Road

Chichester PO236PX

Saturday

Dear John,

　 I got your letter yesterday. Yes, of course you can come and stay next week. I didn’t realize your company was in this area. Actually, it’s lucky that I shall be here, because I have to go away on business myself on Monday — but I shall be back by the time you come. What time will you be arriving? Anyway, I’ll leave a key with my next-door neighbour (at Number 21) just in case you get here before I do.

I’d better give you some directions as to how to get here. When you get to the town, follow the main road as far as the first set of traffic lights and then turn right. Turn left at the next crossing. At the end of this road there’s a roundabout. Go straight across, and Lansdowne Road is the second on the right.

By the way, I hope you won’t mind sleeping on the camp-bed. I’m afraid there isn’t a spare (空闲的) bed, but it’s quite solid, so you should be comfortable enough! I nearly forgot to mention the most important thing — could you bring a sleeping bag?

Well, I must go now — I’ve got to go and collect the car from the garage. I was out in the middle of nowhere yesterday, when it broke down for no clear reason. I had to walk miles before I found a phone-box and finally asked a garage to send someone out to give me a tow（拖走）.

Looking forward to seeing you on Thursday.

　　　　　　　　　　　 Yours,

　　　　　　　　　　　　　　　 Mike

B. he can wait for Mike

C. he can ask Mike’s next-door neighbor for the key

D. he can ask the landlady for the key
