【题目】Since the 1970s,scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.

Recently,two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne,Switzerland,demonstrated (展示) a small robotic wheelchair directed by a persons thoughts.

In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thougts.

Our brain has billions of nerve cells.These send signals through the spinal cord(脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles, Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

Prof.Millan,the team leader,says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. The practical possibilities that BCI technology offers to disabled people can be grouped in two categories:communication,and controlling devices. One example is this wheelchair.

He says his team has set two goals. One is testing with real patients,so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

【1】How did Tavella operate the wheelchair in the laboratory?

A.By controlling his muscles.

B.By talking to the machine.

C.By moving his hand.

D.By using his mind.

【2】Which of the following shows the path of the signals described in Paragraph 5?

A.scalpcomputercapwheelchair

B.computercapscalpwheelchair

C.scalpcapcomputerwheelchair

D.capcomputerscalpwheelchair

【3】Which of the following would be the best title for the text?

A.Switzerland,the BCI Research Center

B.New Findings about How the Human Brain Works

C.BCI Could Mean More Freedom for the Disabled

D.Robotic Vehicles Could Help to Cure Brain Injuries

【题目】For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but______It was only when I turned to meditation(沉思)for a solution that the answer came to me: turn to nature!

The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain(限制) our own spirits, which only leads to depression and stress.

Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre.

If you feel a little low in spirit and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.

1The author walked in a nature reserve in the rain in order to__________.

A. take photos

B. cheer herself up

C. hop along the path

D. find a solution to the project

2The underlined part "to no avail" in Paragraph 1 probably means " __________".

A. uninteresting B. unrelated

C. unsuccessful D. unexpected

3In the author's opinion, __________.

A. a bath can make people relaxed

B. adults should express their inner feelings freely

C. walking in a busy city centre harms people's health

D. depression is usually caused by hard work

4The last paragraph mainly serves as a(n) __________.

A. suggestion B. explanation

C. introduction D. reminder

【题目】The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.

An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill(钻孔) deep in the side of a sandstone mountain. Temperatures in the area never rise above 0C. The seeds will be protected behind walls a meter thick and high-security door.

The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0C. The cold weather would protect the seeds even if the air could not be replaced.

Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.

【1】The project is meant to ______.

A.increase the world’s food output in the future

B.carry out some scientific experiments on plant genes

C.build an exhibition centre of the world’s plant seeds

D.protect crop seeds from dying out in case of possible disasters

【2】Which of the following statements is TRUE according to the above passage?

A.The government of Norway will perform the project alone.

B.Seeds to be collected there were produced ten thousand years ago.

C.Spitsbergen is chosen because it is free of the nuclear war forever.

D.Temperature is a major consideration when choosing the storage place.

【3】We can infer from the text that _______.

A.Norway had meant to build the storage centre about 20 years before.

B.The storage center will greatly promote world agriculture

C.People will get newly-developed seeds from the center every year.

D.There haven’t been any seed storage centers in the world before.

【4】What is probably the best title of the passage?

A.The Best Place to Store Seeds

B.Noah’s Ark(诺亚方舟)of Plant Seeds in Plan

C.Concerns of World Food Supply

D.A New Way to Feed the World
