题目内容

【题目】The sad boy sat on the ground, shouting she was crying.
A.when
B.while
C.as
D.as soon as

【答案】C
【解析】as soon as意为“一……就……”,when,while和as 都有“当……的时候”之意,但是用法有区别,when可以和延续性动词连用,也可以和短暂性动词连用;而while和as只能和延续性动词连用;从句动作在主句动作前发生,只用 when;从句动作和主句动作同时发生,且从句动作为延续性动作时,when,while,as都可使用;当主句、从句动作同时进行,从句动作的时间概念淡化,而主要表示主句动作发生的背景或条件时,只能用 as。这时,as常表示“随着……”;“一边……,一边……”之意。本句意思是:这个伤心的男孩坐在地上,一边大喊一边大哭。根据句意只能选C。

【题目】Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮丧) , physical activity, and life satisfaction.

In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.

“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”

The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

“At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”

A. understand human-animal relationship

【题目】根据短文理解选择正确答案。
D
Recently, a solar-powered (太阳能动力的) plane took to the sky for the first time. It passed an important test on the way to travel around the world.
The plane took off from an airport(飞机场)in Switzerland. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly—never an airplane so big, so light, using so little energy.” said Bertrand Piccard, a leader of the project.
During the 90-minute flight (飞行), the plane did several turns. It climbed nearly 1. 6 km above the countryside.
Engineers(工程师) plan to test a night flight(飞行)before July. Then they will use the results(结果)of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
“We want to fly it day and night with no fuel(燃料),” Piccard said. Piccard and pilot (飞行员)Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the air--and to show off their airplane.
The plane will fly at 70 km per hour on average(平均). That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time.
(1)The passage is probably taken from .
A.a postcard(明信片)
B.a newspaper
C.a comic book
D.an advertisement
(2)The solar-powered plane .
A.is big and heavy
B.uses much energy
C.passed the first flight test
D.will have a night flight after July
(3)How long will it take the solar-powered plane to travel 140 km?
A.About a day and a night.
B.About 5 days.
C.About 2 hours.
D.About 90 minutes.
(4)Which of the following is NOT mentioned(提到) in the passage?
A.During the 90 -minute flight, the solar-powered plane reached a height of 1. 6 km.
B.The solar-powered plane is slower than a car and faster than a bike.
C.Maybe the solar-powered plane will fly with no fuel.
D.It took a long time to build the solar-powered plane.
