About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?

 Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!

 Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.

 The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.

   Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!

三、阅读理解 (共20小题;每小题2分,满分40分)

    阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡

Let us begin by saying what causes our dreams. Our dreams do not come from another world. They are not messages from some outside source .They are not a look into the future, either.

All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry, or tired, or cold , his dreams may include a feeling of this kind. If the covers on your body, such as a quilt or a blanket, have slipped off your bed, you may dream that you are sleeping on ice or in snow. The material for the dream you will have tonight is likely to come from the experience you have today.

So the subject of your dream usually comes from something that has effect on you while you are sleeping(feeling of cold, a noise, a discomfort, etc.)and it may also use your past experiences and the wishes and the interests you have now. This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom.

To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream, here is the story of the experiment. A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton. He would dream he was in hospital and his charming girlfriend was visiting him, sitting on the bed and feeling gently his hands!

There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean. Their explanation of dreams, though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem. They believe that dreams are mostly expressions of wishes that did not come true. In other words dreaming is a way of having your wishes carried out.

36. From the passage we know that our dreams       .

A. are imagination of our daily life               B. are man’s curious look into the future

C. have nothing to do with our feelings              D. are to some degree connected with our feelings

37. In your dream when you feel like eating something it indicates(暗示)that       .

A. you are in a state of being cold    B. you are in a state of being tired

C. you are in a state of hunger       D. you should have had your dinner that day

38. Older children often dream of examinations probably because        .

A. they are interested in exams        B. they are often worried about their studies

C. they hope for better life          D. they show much interest in their studies

39. Some scientists’ explanation of dreams         .

A. is not widely accepted though a bit reasonable        B. gives an exact description of our life

C. provides us with information of dreams                 D. is of no use for us

A small group of people around the world have started implanting(移植) microchips to link the body and the computer.

Mr. Donelson and three friends, who had driven 100 miles from their homes in Loekport, New York, to have the implants put in by Dr Jesse Willemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports.

At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. “I’m set,” he said with a deep breath. He watched as the needle pierced(刺穿) the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined; strengthen his body’s powers through technology.

By putting the chip inside—a radio frequency identification device (RFID)—Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car.

Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks(数据输入插空) inside his body. They might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words “Technology”.

Some doctors have done the piercing in people’s homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling(肿) and redness should last a week.

69. With a RFID implanted, which of the following will Mr. Donelson be able to do?

Make a safety gate open with a knock of a card.

Make bridge and tunnel traffic flow smoothly with an E-Zpass.

Open doors and unlock his car with a wave of his hand.

Turn his body and brain directly into computers.

70. The underlined word “they” in paragraph 5 refer to “___________”.

       A. glass containers                             B. implanted computer chips

       C. data input jacks                                    D. computer and net working students

71. Which of the following would be the best title for the passage?

       A. High Tech, Under the Skin                     B. A Needle, So Magic

       C. Donelson, a Powerful Man                     D. Data-input Jacks, Inside the Body

72. We can conclude from the passage that __________________.

Mr. Donelson has made a large sum of money by the piercing.

the Piercers are people working in the computer field

the piercing has no side effect and it will make people intelligent

the long term effects of these implants are not yet known
