Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer.

This is not a fantasy. A British company, called electro­texiles, has created a wide range of clothes—clothes tha have minds of their own ! Scientists, working for the company, have invented a kind of fabric that can be mixed with flexible electronic materials to create intelligent clothing. The results are electronic garments.

If you think the weather has to be wired to different devices, think again. These designer clothes are wirefree, soft to touch and washable! Like any electronic device, these high­tech clothes have to be powered. Currently, a tiny nine­volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100% shockproof, they say.

The electrotexiles team has also created the world's first cloth keyboard. These keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These “l(fā)ap­tap” devices are all set to take over laptop computers!

Another useful garment is the shirt­cum­mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wears include the denim (牛仔布) jacket with flexible earphones sewn into the hoop and the electronic ski jacket with a built­in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?

60.The electronic garments are similar to other electronic devices in that ________.

A. they feel smooth and soft  

B. they use electricity as power

C. they can be washed in water 

D. they are made from flexible materials

61.How will researchers improve these high­tech clothes?

A. Body heat will be used as power.

B. The wearer will not get shocked.

C. A tiny nine­volt battery will work. 

D. They will get charged automatically.

62.The main purpose of the text is________.

A. to advertise for an English company

B. to predict the future trend of the products in the company

C. to show how rapidly science develops

     You might think tha t"global warming" means nothing more than a rise in the world's temperature But rising
sea levels caused by it have resulted in the first evacuation (撤離) of an island nation-the citizens of Tuvalu will
have to leave their homeland.
     During the 20th century,sea level rose 8-12 inches. As a result.Tuvalu has experienced lowland flooding of
salt water which has polluted the country's drinking water.
     Paani Laupepa, a Tuvaluan government official,reported to the Earth Policy Institute that the nation suffered
an unusaually high number of fierce storms in the past ten years.Many scientists connect higher surface water
temperatures resulting from global warming to greater and more damagingtorms.
     Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an
international agreement calling for industrialized nations to reduce their greenhouse gas emissions (導(dǎo)致溫室效
應(yīng)的氣體排放), which are a main cause of global warming. "By refusing to sign the agreement, the US has
effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived
for thousands of years," Laupepa told the BBC.
     Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
      Tuvalu is not the only country that is vulnerable (易受影響的) to rising sea levels.Maumoon Gayoon,
president of the Maldives, told the United Nations that global warming has made his country of 311,000 an
"endangered nation".
