题目分析:本文讲述了电脑的发展历程,从大到小,从昂贵到便宜;另外,还介绍了机器人的情况。

小题1:根据题干,本句的意思是“但是人们必须给它们一些信息。”“信息”是information。

小题2:本句的意思是“人们能在几秒内找到自己想要的信息。”“秒”是second。所以本题填seconds。

小题3:根据文章,本句的意思是“起初的电脑很贵,而且占很大的空间。”“占据(空间)”是take up。所以本题填up。

小题4:根据上句可知,本句的意思是“它们变得更便宜更小”,故填cheaper。

小题5:根据上下文可知,本句的意思是“人们可以将它们放在桌子上”。“放置”是put或place。

小题6:根据form place to place.可知,应该是“拿着四处走动”“拿”应用carry。

小题7:根据题干,本句的意思是“机器人就是被电脑控制的能动的机器。”“被控制”是controlled。

小题8:本句的意思是“它们能工作很长时间而不抱怨”“无,没有”是without。所以本题填without。

小题9:根据上题和本空的首字母可知,本处应该是变累,故应用tired。

小题10:本句的意思是“一些人担心有一天许多人会因为机器人而失去工作。”“失去”是lose。所以本题填lose。

点评:完成本题有一定的难度,首先应该熟读文章,弄清文章的意思,熟悉电脑的发展历程;其次,应结合文意和句意选择合适的词,注意推断;再次应注意词的时态和固定用法。

填空题

Part 1


·Read the following passages, eight sentences have been removed from the article.
·Choose from the sentences A-H the one which fits each gap.
·For each gap (1-8) mark one letter (A-H) on the Answer Sheet.
Buzz Aldrin, the second man to walk on the Moon, is a long-time fan of space tourism. Aldrin climbed out of Apollo11 hot on the heels of Neil Armp in 1969. (1)
Together with scientists from Purdue University, the Massachusetts Institute of Technology, and the University of Texas, Aldrin is designing spacecrafts that would perpetually cruise between Earth and Mars. (2) "Some day, people will go to Mars on a regular basis," says team member James Longuski, a professor at Purdue. (3)
The average distance between Mars and Earth is 48 million miles. (4)
It sounds like a trip that would require a lot of fuel. According to the engineers, the cyclers may have a natural, renewable "fuel" supply: from the gravitational forces of the Sun, the planets, and their moons.
As a spacecraft travels close to a planet, its flight path is bent, causing it to whip around the planet and significantly increasing its speed (it’s as if the planet’s gravity gives the passing spacecraft a kick into space). (5) It’s not just science fiction: it might help us get Mars with very little fuel on board, in a journey that would take as little as six to eight months.
"The cycler is essentially in orbit around the Sun and makes regular flybys of Earth and Mars," says James Longuski. "Once you put your vehicle into a cycler orbit, it continues on its own momentum, going back and forth between Earth and Mars. (6)
When the cycler flies by Earth, it will be traveling at a speed of about 13,000 miles per hour.
(7) This is sort of like a bus that doesn’t stop," Longuski says. "When it comes by, you have to run alongside of it and grab on."
AIdrin and his group think that the first cycler could be on its way by as soon as 2018. (8) (It seems a long way off now, but it’s closer than you think!)
Fasten your seatbelts and make sure your seatback is in its upright position. Your flight to space may be departing soon.
  • A. These crafts, known as "cyclers", would ferry people and supplies between the two planets, enabling humans to colonize Mars — something that has long been dreamed about in science fiction.
  • B. Most people are convinced that we are going to do this; the only question is when.
  • C. So, if you’re in middle school now, you could be taking a trip to Mars by the time you’re in your thirties.
  • D. To get a sense of just how far this is, try doing this calculation: Given that there are 2,500 miles between New York and Los Angeles, how many times would you have to travel from NY to LA and back to cover the same distance’
  • E. Now, at the age of 72, Aldrin is working on a new project that could put more of his fellow humans in space — namely, on journeys to one of our most fascinating neighbors, Mars.
  • F. This is the "slingshot" trajectory that you may have seen in movies.
  • G. Space taxis will be needed to bring people from the surface of the planet to intercept the cycler.
  • H. You may need to carry some propellant for an occasional boost, but it’s pretty much a free trip after that.
