Question

【題目】

The growth in skyscrapers (摩天大樓) worldwide, most of which have large glass panes, has led to a great need for window washers. Though the job, which earns workers as much as $35 an hour, can be lucrative, accidents are not uncommon. However, the dangerous chore may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (監(jiān)督) from the safety of the ground.

Much like humans, Ozmo, hanging off the sides of the building, uses its arms and brushes to clean the dirt and grime on the glass panes. A 3-D map of the building programmed into its system allows the robot to skillfully move up and down. Computer vision and touch sensors (傳感器) enable it to move out of the way in case of unexpected events, such as the sudden opening of a window. And the robot will self-correct and move around it so as not to break a window.

Unlike other window washers, the robot cleaner does not require soap or Windex to clean the glass. Instead, it uses purified water (純凈水) and a process called reverse osmosis (反滲透) to do the job. It is environmentally friendly.

While it takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers, only making their jobs safer. Human workers will control the robot from below.

Whether Ozmo, which is still undergoing testing, docs as good a job as humans remains to be seen. * Past efforts to use a robot to do this dangerous job have not been successful, because the machines do not have the same eye as humans and often miss the soot (煙垢) collected on window corners.

【1】The underlined word “l(fā)ucrative” in the passant’ probably means “________”

A.安全的B.危險的C.賺錢的

【2】The second paragraph mainly tells us

A.why Ozmo is much more intelligent than human workers

B.how Ozmo works to clean the glass smartly

C.what makes Ozmo an intelligent window cleaning robot

【3】What does Ozmo use to clean the glass?

A.Purified water.B.Soap.C.Grime or soot.

【4】To finish the task of cleaning the windows of a 40-story glass building, Ozmo spends ________ hours less than a cleaner.

A.560B.400C.1,360

【5】Which of the following is TRUE about Ozmo?

A.As an intelligent window cleaning robot. Ozmo is successful.

B.Ozmo does harm to the environment while cleaning the window.

C.Ozmo can make human window washers do their jobs safely.

Answer 1

【答案】

【1】C

【2】B

【3】A

【4】C

【5】C

【解析】

這篇短文主要介紹了擦窗機器人——Ozmo。在摩天樓擦玻璃是件危險的事情，現(xiàn)在機器人Ozmo可以幫助人們完成這項危險的工作。但是Ozmo也有自己的缺點，還不能完全代替人類。

【1】

詞句猜測。根據(jù)上文“Though the job, which earns workers as much as $35 an hour”擦窗工人每小時能賺35美元。由此可知lucrative的意思是“獲利的，賺錢的”。故選C。

【2】

段落大意。A. why Ozmo is much more intelligent than human workers為什么奧茲莫比人類更聰明；how Ozmo works to clean the glass smartly奧茲莫如何巧妙地清潔玻璃；what makes Ozmo an intelligent window cleaning robot是什么讓Ozmo成為智能擦窗機器人。通讀整個第二段可知，本段主要介紹了Ozmo是如何巧妙地擦玻璃的。故選B。

【3】

細節(jié)理解。根據(jù)文中“Unlike other window washers, the robot cleaner does not require soap or Windex to clean the glass. Instead, it uses purified water (純凈水) and a process called reverse osmosis (反滲透) to do the job.” 與其他窗戶清洗機不同，機器人清洗機不需要肥皂或Windex來清洗玻璃。相反，它使用純凈水和一種叫做反滲透的工藝來完成這項工作。它是環(huán)保的。故選A。

【4】

數(shù)字計算。根據(jù)文中“While it takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours.” 雖然一座40層的玻璃建筑的窗戶需要3名清潔工每人480個小時來清潔，但機器人將在短短80小時內(nèi)單槍匹馬地完成這項任務(wù)。也就是一個擦窗工人需要1440小時。而Ozmo只用80小時。1440-80=1360。故選C。

【5】

推理判斷。根據(jù)文中“Past efforts to use a robot to do this dangerous job have not been successful,” 過去用機器人做這項危險工作的努力并沒有成功�？芍�選項A“As an intelligent window cleaning robot. Ozmo is successful.”說法錯誤；根據(jù)文中“Instead, it uses purified water (純凈水) and a process called reverse osmosis (反滲透) to do the job. It is environmentally friendly.” 相反，它使用純凈水和一種叫做反滲透的工藝來完成這項工作。它是環(huán)保的�？芍�選項B“Ozmo does harm to the environment while cleaning the window”說法錯誤的。根據(jù)文中“However, unlike other robots, Ozmo will not replace human workers, only making their jobs safer.” 然而，與其他機器人不同，Ozmo不會取代人類工人，只會使他們的工作更安全。可知，選項C“Ozmo can make human window washers do their jobs safely.”是正確的。故選C。
