题目内容

Researchers at the University of Bedforshire have developed a new technique for powering electronic device（装置）. The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio waves as power.

Believed to be a world first, the team claims it could eventually get rid of the need for conventional batteries. The university has now applied for a patent(专利) application to secure the only rights to the technique.

Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.

The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy---like light waves, sound waves or wind waves---in theory, these waves could be used to create power.

“The new area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”

The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working pattern and maybe partner up with the right people and take this to a full product in due course,” he said.

“Power harvesting has a really important part in our future, because, just in this country, we leave somewhere between 20,000 and 30,000 tons of batteries in landfill（垃圾填埋）sites every single year－that is poisonous chemicals going into the ground.”

He added that development of the product could also be “commercially（商业） beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.

Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple said, “This type of work is a reflection of the university’s growing reputation and experience in carrying out creating research.”

A. reading B. to read C. read D. reads

The wedding（婚礼） took place in a Birmingham hotel. The bride and her father arrived in a new black American sports car. Her father looked nervous and uncomfortable in front of the cameras. The bride wore a silk wedding dress. She smiled nervously at the waiting photographers and went to a room on the first floor where she met her future husband for the very first time.

Carla Germaine and Greg Cordell were the winners of a radio station’s competition. The aim of the competition was to find two strangers prepared to marry without having met each other. Miss Germaine, 23, is a model. Mr. Cordell, 27, is a TV salesman. They were among the two hundred people who entered for a particular “experiment” organized by BMRB radio in Birmingham, England. Greg and Carla were among eight finalists who were interviewed live on radio. They took a lie detector （测谎仪）test and the station also spoke to their friends and family about their personalities. The competition judges included an astrologer（占卜家）who declared that they were suited.

The couple celebrated their wedding with a wedding breakfast and a party for 100 guests in the evening, but not everyone shared their joy. Miss Germaine’s mother looked anxious through-out the wedding and Mr. Cordell’s parents are reported to be less than delighted.

Organizations, including the marriage guidance service Relate, have criticized the marriage. As one expert put it, “we have enough problems getting young people to take marriage seriously. Marriage should always be about love.”

The couples are now on a Caribbean honeymoon followed by journalists. Their other prizes include a year’s free use of a wonderful apartment in the centre of Birmingham, and a car. But will it last?

A. Two Strangers and a Wedding. B. A Wedding Based on love.

C. A Short--lived Marriage. D. A Well--Matched Couple.

When a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is danger. The rabbit has told them something without making a sound. It has given them a signal（信号）.

Many other animals use this kind of language. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.

Some animals say things by making sounds. A dog barks, for instance, when a stranger comes near. A cat purrs （咕噜咕噜） when pleased. Some birds make several different sounds, each with its own meaning.

But human beings have something that no animal has ---a large number of words which have the meanings of things, actions, feelings or ideas. We are able to give each other information, to tell or inform other people what is in our mind or how we feel. By writing words down we can remind （提醒）ourselves of the things that have happened, or send messages to people far away. No animals can do this. No animals have the wonderful power of language.

No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.

People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example, contains four or five hundred thousand words. But we don not know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we meet a new word, look it up in the dictionary. A dictionary is the most useful book.

It was a winter morning, just a couple of weeks before Christmas. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.

The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries, saving us from having to walk a long distance from where we live.

I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.

People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had an amazing effect in our lives because it strengthened our faith in humanity(人性)as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

1.Why was the bike so important to the couple?

A. The man’s job was bike racing.

B. It was their only possession(财产).

C. It was a nice Kona 18 speed.

D. They used it for work and daily life.

2.We can infer from the text that___________.

A. the couple worked 60 hours a week

B. people were busy before Christmas

C. life was hard for the young family

D. the stranger brought over the bike

3.How did people get to know the couple’s problem?

A. From radio broadcasts B. From a newspaper.

C. From TV news. D. From a stranger.

4.What do the couple learn from their experience?

A. Strangers are usually of little help.

B. One should take care of his bike.

C. News reports make people famous.

D. An act of kindness can mean a lot.

In the summer holiday, we travelled to Qingdao and paid visit to my uncle there. It’s a long and bored journey. But the moment I arrived, I fall in love with the city. It’s such beautiful a city that I can hardly find any word to describe it. The streets are cleaning and the sky is blue. If you walk along the coast, you can feel the wind to blowing on your face. The sea is vast and sometimes you can find a boat or a ship. You may also do some fishing as far as it is permitted. Moreover, I think the driver there drive too fast in the street. You can never be too careless when crossing the street.
