  【词语辨析】

  1. maybe / may be

  maybe 是副词,意为“大概, 可能,或许”,一般用于句首。May be是情态动词,意为“可能是...,也许是...,大概是...”.

  The baby is crying. Maybe she is hungry.

  The woman may be a teacher.

  2. a few / few / a little / little

  People can live to 100, but few people can live to 150.

  There is little time left. I won’t catch the first bus.

  Could you give me a little milk?

  3. hard / hardly

  hard作形容词,意为“困难的,艰苦的,硬的”;作副词,意为“努力地,猛烈地”。hardly为副词,意为“几乎不”。

  The ground is too hard to dig.

  I can hardly understand them.

  It’s raining hard. The people can hardly go outside.

  4. As for homework , most students do homework every day .

  as for...意思是“至于;关于”,+名词、代词或动词的-ing形式(即动名词)。

  如: As for him,I never want to see him here.

  至于他,我永远不希望在这里见到。

  As for the story,you'd better not believe it.

  关于那故事,你最好不要相信。

  5. That sounds interesting.

  这是“主语+系动词+表语”结构的简单句。sound(听起来),look(看起来),smell(闻起来),taste(尝起来),feel(觉得),seem(好象),grow(变得),get(变得)等词在英语中可用作系动词,后跟形容词作表语。如:

  It tastes good. 这味道好。

  The music sounds very sweet. 这音乐听起来很入耳。

  The smoke grew heavier and heavier. 烟雾变得越来越浓了。

  6. percent 名词,意为“百分之……”

  百分数的表示方法:基数+ percent (不用复数形式),percent做主语时,谓语动词的数要根据其后面的名词来确定。

  50%:fifty percent 百分之五十

  Fifty percent of the apples are bad. 50%的苹果都坏了。

  Twenty percent of the meat is in the fridge. 20%的肉都在冰箱

  7. not… at all 意为“一点也不”,not应放在be动词、情态动词或助动词之后。

  The story isn’t interesting at all. 那个故事一点也没有趣。

  8. It is + adj. to do sth. 做某事是……的。

  It is interesting to play computer games. 玩电脑很有趣。

  9. take, spend, pay

  It takes sb. some time to do sth. 意为“花费某人……时间来做某事”。

  人(sb.) spend 时间/钱 on sth. “买某物花了……钱”。

  人(sb.) spend 时间/钱 (in) doing“花费多少时间来做某事”。

  pay 的主语必须是人,而“花钱买某物”为pay...for...

  10. however 副词,意为“然而,可是”,表示转折关系,可放在句首、句中、句末。
