13.-Have you cleaned your room_____?
-Yes,I've_____cleaned it.( 。
A.already,alreadyB.yet,yetC.already,yetD.yet,already

分析 ---你打掃你的房間了嗎?
--是的,我已經(jīng)打掃了.

解答 答案:D.
根據(jù)-Have you cleaned your room_____?-Yes,I've_____cleaned it.可知---你打掃你的房間了嗎?--是的,我已經(jīng)打掃了.這里考查already,yet的區(qū)別.a(chǎn)lready用在肯定句中,yet用在否定句或疑問句中.故選D.

點評 比較和分析already,yet的不用含義及其用法是解答該題的關(guān)鍵;還要根據(jù)句中信息正確推測該句句意,進(jìn)而作出解答.

1.Nowadays,many children spend hours a day looking at computer screens or other digital (數(shù)碼的) products.Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (視力綜合癥).
Nathan Warford is an optometrist(驗光師) in the US.He says he has seen more children having eye problems."More children come into my office because their parents have noticed that they have headaches (頭疼)or red eyes,or because their degree of short-sightedness appears to be increasing (增加)very fast and they're worried,"he said.
Dr.Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache,some children don't tell their r parents,because they don't want their games or the computer to be taken away.Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life.If eyes can't stay wet or are too tired,they will not be protected like normal.

38.People blink aboutAas they normally do when they use computers.
A.a(chǎn) third as much 
B.two thirds as much 
C.half as much   
D.a(chǎn)s much
39.From the passage,we can learn thatC    
A.children should blink as much as possible
