Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp（安培） current to store this electricity, and a lamp whose bulb is a light-emitting diode（二极管）. The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.
The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card—for as little as a dollar—on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 months—the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell.
In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.
According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.

I'm really nervous opening Chatroulette （a website）．I don't know if I'm more scared of the possibility of coming face-to-face with a naked （裸体的） guy doing improper things, or the possibility of having to speak to someone normal．But it's that uncertainty that's caused the "game" to explode into an Internet phenomenon．
So, I hesitantly click "play"．My face appears in a small box to the left of the screen．I'm a 22-year-old guy, wearing jeans and a T-shirt, and sitting in my warmly lit bedroom —not too threatening, I think．Believing I look welcoming and friendly, I open all features: visual, audio and text．The user can disable these at any time if they feel uncomfortable．
Quickly I find myself face-to-face with my first "partner"．A guy with glasses is staring back at me．He looks like he spends too much time in front of the computer．"Hey", I say, "how are you going?" "Good," says the guy．Sensing that he was not going to be very talkative, I hit the "next" button．
Just like that, I'm thrown across the world into someone else's bedroom．This time it looks like a middle-aged woman．I must have hit gold because 85 percent of Chatroulette users are male, according to the Wall Street Journal．She's wearing sunglasses and smiles back．Before I can even say a word, she "nexts" me．"WHAT?!"
Then, I fly through the Internet and arrive at my next partner．My nightmare, a man is sitting in his computer chair half-naked taking off his pants．Argghh! "Next, next, next!" For the next 30 minutes I keep my cursor （光标） over the "next" button．My experiences continue to be short, shocking, and largely uninteresting．I discouragingly hit "next" after seeing another naked man, and decide to end my session and close the window．This wasn't "the new social media experience" I was hoping for．Maybe it was just a little bit too random （随机的）．
64．It is the author's __________ that leads him into Chatroulette．
A．curiosity          B．unwillingness    C．enthusiasm          D．ignorance
65．The underlined word "disable" in Paragraph 2 means __________．
A．store                  B．close                C．misuse                D．copy
66．Among all the partners, __________ seemed to be the least interested in talking with the author.
A．the guy with glasses                      B．the middle-aged woman
C．the man in his computer chair            D．the last man mentioned
67．What is the author's attitude toward Charoulette?
A．Positive．           B．Supportive．       C．Objective．         D．Negative．

Wugging, or web use giving, describes the act of giving to charity at no cost to the user. By using Everyclick.com, which is being added to a number of university computers across the UK, students can raise money every time they search, but it won’t cost them a penny.

Research shows that students are extremely passionate(热情的)about supporting charity（慈善）--- 88％of full time students have used the Internet to give to charity. This figure is high because this age group is often the least likely to have their own income. 19％ of 22 to 24 year olds have short-term debts of more than￡5，000. With rising personal debt levels in this age group, due to university tuition fees or personal loans and a lack of long-term savings, traditional methods of donating to charity are often not possible.

Beth Truman, a 21year old recent university graduate has used Everyclick.com to donate to her chosen charity, the RSPCA, for two years and has seen the “wugging” movement grow in popularity with students. “When you’re at university you become more socially aware, but it's sometimes hard to give to others when you have little money yourself,” says Beth. “Wugging is great for people in this age group as it allows them to use the technology on a daily basis to give to charity, without costing them a single penny.”

Wugging is perfect for people who want to be more socially aware and supportive but don’t feel they have the means to do so. Students using the web can raise money for causes they care about without costing them anything in terms of time or money, and charities get a valuable source of funding.

Everyclick.com works like any other search engine, allowing users to search for information, news and images but users can decide which of the UK’s 170,000 charities they would like to support through their clicks. Everyclick.com then makes monthly payments to every registered charity. Launched in June 2005, Everyclick.com is now the eighth largest search engine and one of the busiest charity websites in the UK.

3.From the passage, we can conclude that _______.

A. most full time students contribute to charity on the Internet every day

B. Everyclick.com helps students pay for the college education

C. “Wugging” is a win-win idea for both students and charities

D. Everyclick.com is the most successful search engine in the UK

4.What would be the best title for this passage?

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

1.What can we learn from the first paragraph?

A．Bikes should be made more comfortable to ride.

B．You can improve your bicycle for science research.

C．Many inventions are connected with the bicycle.

D．Bicycles are the best way to go about

2.Which of the following is true according to the passage?

A．ISEF is an exhibiton displaying bicycle experiments designed by students.

B．Looking closely at things you are concerned about can lead to scientific research.

C．Renato’s improvement of the bicycle has solved the country’s great problem.

D．Renato’s special bicycle will soon be put into use in remote areas.’

3.The underlined word “address” in the third paragraph probably has the same meaning as _______.

A．make address written

B．give up

C．work at

D．speak at

4.Renato’s special Multibike has all the following EXCEPT ________.

A．making knives sharp	B．mixing any kind of drinks
C．producing electricity	D．operating a machine with its own electricity

5.It can be inferred that Renato’s special bicycle is mainly designed for ________.

A．distant areas in the rainforest without electricity.

B．the use of his own family to make life easier.

C．the competition of ISEF to win money to support remote rainforests

D．enough exercise by pedaling it

The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.

The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying(净化)factory. There it can be filtered(过滤) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

47. The way to stop wasting water is to ________ .

A. do experiments with water

B. purify the used water and reuse it

C. use fresh water once again

a. to have the used water filtered b. to put chemical in it

c. to pipe it to the user

d. to pipe the used water to be purified in a factory.

A. dabc B. bcda C. bdca D. dcba

49. There wouldn't be enough water for us if we didn't ________ .

A. turn to the ocean for more water

B. reuse used water and make use of seawater

C. make fresh water from the seawater

D. take steps to reuse all water on earth

50. The word "it" underlined in the last paragraph refers to ________ .
