分析 本文是一篇記敘文,記敘了作者家鄉(xiāng)Poland的飲食習(xí)俗和文化,提到家鄉(xiāng)糧食匱乏和歌頌家鄉(xiāng)全家一起吃飯的場景,并肯定這一風(fēng)俗對個人成長的積極意義.
解答 13.B 細(xì)節(jié)理解題.根據(jù)文中第一段"I believe that my country,Poland,is a perfect example for a place where food is particularly important.When we were little children,we began to understand how much a loaf of bread meant to our parents"可知從作者是個小孩的時候就開始明白食物的重要性.所以選B.
14.C 細(xì)節(jié)理解題.根據(jù)文中第一段"But though we no longer make our food from scratch,some customs have been kept-that's why I feel so sorry every time I have to throw any food away"可以推斷出我仍然保留著(珍惜食物)的習(xí)慣,所以會為了不得不扔掉食物而感到難受.所以選C.
15.D 推理判斷題.根據(jù)文中第二段"You can share other members'troubles and successes,give your children some attention,or just sit down for a moment instead of rushing through life aimlessly"可知目前在波蘭很多家庭還是一起吃飯,吃飯時互相分析成功和麻煩,互相了解更多.所以選D.
點(diǎn)評 閱讀理解題測試考生在閱讀基礎(chǔ)上的邏輯推理能力,要求考生根據(jù)文章所述事件的邏輯關(guān)系,對未說明的趨勢或結(jié)局作出合理的推斷;或根據(jù)作者所闡述的觀點(diǎn)理論,對文章未涉及的現(xiàn)象、事例給以解釋.考生首先要仔細(xì)閱讀短文,完整了解信息,準(zhǔn)確把握作者觀點(diǎn).

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's 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 thoughts.
"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(頭皮) 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. Milan, 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.BCI is a technology that can _________________.
A. help to update computer systems
B. link the human brain with computers
C. help the disabled to recover
D. control a person's thoughts
2.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.
3.The team will test with real patients to .
A. make profits from them
B. prove the technology useful to them
C. make them live longer
D. learn about their physical condition
4.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
