题目内容
13.Many adults enjoy a cup of coffee to have extra energy on a sleepy morning,and astronauts are no exception.But having a drink in space isn't as easy as it is on the earth.You have to come up with a whole new way to drink,and that's what scientists are trying to do."The coffee would be very hard to control in a normal cup,"said physics professor Mark Weislogel."You'd have to shake the cup toward your face and hope that some of the hot liquid floats toward your mouth.When it comes to guessing what liquids will do in new systems,we are often in the dark."
Weislogel believes that creating a big zero-gravity cup would help improve the lives of astronauts in space,so he and other researchers per formed a series of experiments with liquids on the International Space Station (ISS) to see how they move upwards on surfaces in zero gravity.
In one of the tests,they placed two surfaces very close together to create a very narrow tunnel.They wanted to see if liquid would easily flow up the tunnel.In another test,the researchers tried to figure out the best angle to place the narrow tunnel at so that the liquids would travel along the corners.
The end result is a cup that doesn't look like a normal coffee cup at all.One side of the cup has a very sharp angle and,in zero gravity,the liquid naturally"flows"up that angled side of the cup,right up to the drinker's lips.
The zero-gravity coffee cup is currently being tested on the ISS by astronaut Don Pettit,who worked with the researchers and helped them invent it."As you sip (啜饮),more liquid keeps coming,and you can enjoy your coffee in a weightless environment-clear down to the last drop,"said Pettit,who thinks that future humans on Mars will be using this kind of cup to drink during celebrations!

分析 本文主要介绍了科学家们为了让宇航员在没有重力的太空中喝咖啡而发明的一种新型杯子
解答 ACDAB
61.答案 A推理判断题 根据第一段第二、三句可知,宇航员们在太空喝咖啡有困难,从而引出下面的内容,故选A.
62.答案 C 句意猜测题 根据第一段的You have to come up with a whole new way to drink,and that's what scientists are trying to do和第二段的When it comes to guessing what liquids will do in new systems等可知,在太空中喝咖啡的时候,关于咖啡是怎样流进一个人的口中,这一点还是未知的,故选C.
63.答案 D 细节理解题 结合第五段的One side of the cup has a very sharp angle and,in zero gravity,the liquid naturally"flows"up that angled side of the cup,right up to the drinker's lips可知,科学家们发明的这种杯子可以使咖啡自己流向喝咖啡的人的口中,故选D.
64.答案 A 推理判断题 从倒数第二段的As you sip (啜饮),more liquid keeps coming,and you can enjoy your coffee in a weightless environment-clear down to the last drop可知,他认为这种杯子是非常实用的.
65.答案B 主旨归纳题 本文主要介绍了科学家们为了让宇航员在没有重力的太空中喝咖啡而发明的一种新型杯子,因此选B.
点评 1、要想做好科普英语阅读理解题,同学们就要注意平时多读科普知识类文章,学习科普知识,积累常见的科普词汇,从根本上提高科普英语的阅读能力.
2、要熟悉科普类文章的结构特点.科普类文章一般由标题(Head line),导语(Introduction),背景(Back ground),主体(Main body)和结尾(End)五部分构成.标题是文章中心思想高度而又精辟的概括,但根据历年的高考情况来看,这类阅读理解材料一般不给标题,而要同学们选择标题.导语一般位于整篇文章的首段.背景交待一个事实的起因.主体则对导语概括的事实进行详细叙述,这一部分命题往往最多,因此,阅读时,同学们要把这部分作为重点.结尾往往也是中心思想的概括,并与导语相呼应,命题者常在此要设计一道推理判断题.
3、在进行推理判断时,同学们一定要以阅读材料所提供的科学事实为依据,同时所得出的结论还应符合基本的科普常识.
