.A: How often ______ she exercise?　　B: Twice a week.

A. do B. does C. doing D. did

B 【解析】本題考查對動作發(fā)生的頻率提問，主語是第三人稱單數(shù)，助動詞用does，故選B。

My brother has ______ friends.

A. a lots of B. a lot C. lots of D. lot of

C 【解析】句意：我的哥哥有很多朋友。a lots of形式錯誤；a lot很多，大量，修飾動詞；lots of很多；lot of形式錯誤。lots of = a lot of 意為“許多”，修飾可數(shù)名詞復(fù)數(shù)。故應(yīng)選C。

______ I have the healthy habit, ______ I’m not very healthy

A. Although, but B. Although, / C. Although, so D. But, /

B 【解析】試題分析：句意：雖然我有健康的習(xí)慣，但是我不健康。根據(jù)句意第一空應(yīng)是although（雖然）；英語中although和but不能同時出現(xiàn)，所以此題選B。

My father eats enough vegetables, and now he is ________ good health.

A. at B. for C. in D. with

C 【解析】句意：我的父親吃足夠的蔬菜，現(xiàn)在他很健康。at在具體時刻或地點；for為了，因為；in在…里面；with和…一起。in good health是固定短語，意為“身體健康”。故選C。

Miss Yang likes movies, but she ________ goes to the movies. She doesn’t have enough time.

A. always B. often C. usually D. hardly ever

D 【解析】句意：楊老師喜歡電影，但是她幾乎沒有去看過電影，她沒有足夠的時間。always總是；often經(jīng)常；usually通常；hardly ever幾乎不。后面的“她沒有足夠的時間”說明她不常去看電影。故應(yīng)選D。

－How ______ milk would you like?

－One kilo.

A. many B. much C. heavy D. often

B 【解析】句意：-你想要多少牛奶？-一公斤。many許多，修飾可數(shù)名詞復(fù)數(shù)；much許多，修飾不可數(shù)名詞；heavy重的，how heavy多重；how often多久一次，提問頻率。句中牛奶為不可數(shù)名詞，對不可數(shù)名詞的量提問應(yīng)該用how much。故應(yīng)選B。

－Do you think eating too much food is ________ us?

－I don’t think so. We should do some exercise, I think.

A. good for B. good to C. bad for D. bad to

A 【解析】句意：-你認(rèn)為吃太多東西對我們有好處嗎？-我不這樣認(rèn)為，我想我們應(yīng)該做一些鍛煉。短語be good for表示“對……有好處”。be good to對某人友好；be bad for對…有害；be bad to對某人不好。根據(jù)句意可知，這里表示對…有好處，故選A。

－Why did you sleep so late yesterday?

－Because I wanted ________ today’s math test.

A. study B. study for C. to study D. to study for

D 【解析】句意：-你昨天為什么睡這么晚？-因為我想為今天的數(shù)學(xué)考試復(fù)習(xí)。study學(xué)習(xí)；study for為…而學(xué)習(xí)；to study動詞不定式；to study for動詞不定式。動詞want后接不定式，所以選項A和B是錯誤的；study for表示“為……學(xué)習(xí)”。故應(yīng)選D。

Eating lots of vegetables and enough meat can___________you healthy all the time.

A. have B. get C. keep D. stay

C 【解析】試題分析：句意：吃很多蔬菜和足夠的肉能讓你一直保持健康。保持用keep。故選C。

－ _______ do you go shopping?

－Every day.

A. How often B. How many C. When D. How long

A 【解析】句意：-你多久購物一次？-每天。How often多久一次，提問頻率；How many多少，提問數(shù)量，修飾可數(shù)名詞復(fù)數(shù)；When什么時候；How long多長時間。從答語every day 中可知是對頻率提問，故選A。
