A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.

Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

The device was built for the United Nations’ child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.

The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

“It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”

The device has been put on show at the Gothia Cup-the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, said the machine had helped raise awareness for UNICEF, but in reality had its limitations.

“People haven’t produced as much sweat as we hoped – right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

1.Which of the following is the disadvantage of the sweat machine?

A. It takes too long for the machine to produce water.

B. The amount of water the machine produces is rather limited.

C. It costs a large amount of money to build the machine.

D. The water processed by the machine is not clean enough.

2.UNICEF is mentioned in the text to ________.

A. show how the sweat machine works

B. explain why the sweat machine was invented

C. show the importance of the United Nations

D. tell us who invented the sweat machine

3.What did Mattias Ronge think of the sweat machine?

A. It could only be used in summer.

B. It did not work at all.

C. It was not worth popularizing.

D. The water it produced tasted sweet.

4.The text is written mainly to tell us that ______________.

A. a machine which turns sweat into drinking water is invented

B. 780 million people in the world lack access to clean water

C. a better solution to purifying dirty water is discovered

D. the pill which turns dirty water into clean water is produced

Obama, Lady Gaga and Steve Jobs—what do they have in common? They are, of course, all Americans. And according to a survey by social networking site baidu. com, they all best illustrate(举例说明) the word “cool”.

But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.

Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy. “Cool” relates to ideas of grace under pressure.

“In Africa, ” he writes, “coolness is a positive quality which combines calmness, silence, and life.”

The modern idea of “cool” developed largely in the US in the period after World War II. “Post-war ‘cool’ was in part an expression of war-weariness (厌战情绪), ... it went against the strict social rules of the time,” write sociologists Dick Pountain and David Robins in Cool Rules: Anatomy of an Attitude.

But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl, smokes cigarettes, wears a leather jacket and beats up bullies. In the movie, Dean showed what “cool” would mean to American young people for the next 60 years.

Today the focus of “cool” has changed to athletics (体育运动) stars. Often in movies about schools, students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.

But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.

“Call it the Harry Potterization of America—a time when being smart is the new cool,” writes journalist Joe Sunnen.

1.If you were considered “cool” in Africa in the 15th century, you ________.

A. thought and acted differently from the majority

B. had a calm and quiet attitude towards life

C. didn’t observe rules and authorities

D. had all kinds of “bad” manners

2.The heroes in Varsity Blues and John Tucker Must Die are likely to be those who ________.

A. do very well in their studies

B. are very skilled at sports

C. are good at chess and other thinking games

D. have supernatural powers like Harry Potter

3.Which of the following is NOT true according to the article?

A. It is generally considered “cool” to be independent-minded and not to follow the crowd.

B. “Cool” was used as early as the 15th century.

C. Disobeying one’s parents and the authorities is considered “cool” among American young people nowadays.

D. Getting the first place in an exam can also be considered “cool”.

4.What does the article mainly talk about?

A. The origin of the word “cool”.

B. The kinds of people who are “cool”.

C. The changing meaning of the word “cool”.

D. How to be a “ cool” person.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

For people with thousands of pages to read, speed reading seems like manna (甘露) from heaven. In addition, speed reading helps lighten the load of information you have to absorb since it provides a filter that you can use in screening all bits of information before you approach it.

1. Examining how much information you need will help you identify how you should read a certain document to maximize your learning and comprehension. Thorough reading may no longer be necessary in some cases, such as when you only need an outline of a certain document.

Another skill that can ease the burden of a reader is the ability to read words in blocks. Make sure you do not spend too long on a certain block. 2. This will also make reading less tiresome and boring.

To master this important skill, you have to practice reading more and more words in a certain block at a time. A suggestion shared by some experts regarding this step is to increase the distance between you and the document you are reading. If you can read more and more words in one block, you can cut down on the time it usually takes you to read a certain text and you will be able to read more in a shorter period.

Readers should also practice reducing the number of times they go back to previous sections or blocks. Using a pointer such as the tip of a pencil or pen can also help to make the flow of your reading smoother and faster. 3. Thus, your speed in reading will largely depend on the speed of the movement of your pointer.

If you still find yourself confused about the topic even after you have finished reading the document, do not re-read right away. Re-reading immediately will just lead to slower speed in reading. 4. Getting your own reading corner will also help.

5. Continue practicing and practicing the techniques aforementioned and soon, you'll achieve the reading speed that will work best for you.

A.In this technique, your eyes will follow the tip of the pointer.

B.This saves time and reduces the effort that you have to make.

C.Taking a short break first is recommended before reading the material again.

D.As a final note, the most important point is consistent and deliberate practice.

E.Your invaluable time can be saved if you can have your reading speed doubled.

F.The first step to increase your reading speed is to identify the specific information you need.

G.Reducing the time you spend on a specific number of words in a block will make no big difference.

If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.

“The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components,” Siegel explains on his website. “It is low-cost, durable and easy to use.”

The Bikealarm was designed as part of Siegel’s Bachelor’s degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thieves the moment they begin to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram / car and a serious theft.

Siegel created a working model of an alarm that would sound when it sensed movement, but wasn’t initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit,” he says.

Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size.

The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.

1.When it senses movement, the RFID Bikealarm will _____.

A. make a warning sound

B. fasten the bicycle tightly

C. shake the bicycle quickly

D. call the police automatically

2.Which of the following shows the right position of the RFID Bikealarm on a bicycle?

A. B.

C. D.

3. What do we know about the RFID Bikealarm?

A. It can’t tell between specific events.

B. It is very difficult to use.

C. It uses a kind of battery for power.

D. It depends on Bluetooth technology.

4. It can be inferred from the last two paragraphs that ______.

A. the electronic circuit is a little larger

B. it’s very easy to make a Bikealarm

C. it costs too much at present

D. not many Bikealarms are produced
