——____ do you visit your

——Once every two weeks.

A. How long B. How soon C. How much D. How often

解析:D 根據(jù)答語Once every two weeks“每兩周一次”，可知問句問的是動作發(fā)生的頻率，應(yīng)用how often，故選D。

思維拓展

①how often通常用來詢問動作發(fā)生的頻率，答語一般用once“一次”，twice, three times a day“一天(兩、三)次”，sometimes“有時(shí)”，never“從不”，very often“經(jīng)?！钡?。

③how far“多遠(yuǎn)”，對距離提問。

④how much用來提問不可數(shù)名詞數(shù)量的多少或?qū)r(jià)格提問。

知識探究

how many意為“多少”，其后要加可數(shù)名詞復(fù)數(shù)形式；how much也意為“多少”，其后要加不可數(shù)名詞。how many與how much的共同點(diǎn)是它們都是對數(shù)量進(jìn)行提問的常用語。例如：

——How many books do you have?

——Three.

——How much milk do you want?

——A kilo.

考點(diǎn)2 some time, sometime, sometimes, some times的區(qū)別

①sometimes的意思是“有時(shí)候”，是表示動作發(fā)生頻率的副詞。

②some times的意思是“幾次”，表示動作發(fā)生的次數(shù)。

③sometime的意思是“某時(shí)；曾經(jīng)”。

④some time的意思是“一段時(shí)間”。

考點(diǎn)3 情態(tài)動詞can，may與must的區(qū)別

The light in the office is off. The teacher ____ be there now.

A. may B. cant

C. musnt D. must

解析:B 本題考查情態(tài)動詞的用法及句意的理解。句意為：辦公室的燈關(guān)了，老師現(xiàn)在不可能在那兒。may是情態(tài)動詞，表可能性；must意為“一定”，must be表肯定推測；mustnt意為“不許可，不應(yīng)該”；cant是can的否定式，意為“不會，不可能”。A、C、D放入句中都不符合題意。

單項(xiàng)選擇

A. Maybe B. May be

C. May D. Can

考點(diǎn)5 ill與sick的區(qū)別

Im going to visit the ____ teacher who has been ____ for

several days.

A. ill; sick B. sick; ill

C. well; ill D. ill; ill

解析:B sick與ill二者意思雖相同，都可意為“生病的”，但sick常作定語，而ill常作表語。ill還可意為“壞的”。well表示“好的”，與題意不符，故C是錯(cuò)誤選項(xiàng)。teacher是名詞，前面要用定語來修飾，因此第一個(gè)空填sick。第二個(gè)空前是系動詞be，因此要用形容詞作表語，故填ill。句意為：我打算去看病了幾天的老師。

考點(diǎn)7 固定短語have a sore throat和情態(tài)動詞should

——I have ____.

——You should ____ down and rest.

A. a sore throat; lie

B. a throat sore; lie

C. sore throat; to lie

D. a sore throat; lying

解析:A 表示“哪兒不舒服或有什么病”動詞用have,其結(jié)構(gòu)為“have+a+病名”?！吧ぷ油础币霉潭ㄔ~組have a sore throat，因此可排除B、C。should是情態(tài)動詞，后面要加動詞原形，因此選A，排除D。

思維拓展

在“have+a+病名”結(jié)構(gòu)中，注意a在此不表示數(shù)量“一”，而屬于不定冠詞加名詞表示一類事物。

should是情態(tài)動詞，是在提出建議時(shí)的常用詞，后面接動詞原形，其否定形式為shouldnt。
