八年级上册units 1-3 知识归纳
一、词语辨析：
1、little, a little, few, a few
中考题：
（1）“what are you going to buy?”“i’m going to buy ______ bananas.”
a. a little b. a few c. little d. few 1997年福建省中考题
【评】答案是b。此题考查a little / little与a few / few的用法区别。a little / little修饰不可数名词：a little意为“一点儿”；little意为“几乎没有”，有否定含义。a few / few修饰可数名词：其中a few意为“几个”，有肯定含义；few意为“少数几个”，有否定含义。此句是肯定句，且banana是可数名词，故选b。
（2）—“can you speak chinese, peter?” —“yes, but only .”
a. little b. few c. a little d. a few
（3）—“can you speak chinese, peter?” —“yes, but only .”
a. little b. few c. a little d. a few
（4）the text is very easy for you . there are _______ new words in it .
a. a few b. a little c. few d. little
（5）the english novel is quite easy for you. there are new words in it.
a. a little b. little c. a few d. few
2、maybe, may be
maybe是副词，在句子中不能作谓语，意为“也许”，它通常放在句首；may be是情态动词 may + be 构成谓语，意为“可能是”。如：
maybe they will win the football game this time.(= they may win the football game this time.) 也许这次他们会赢得这场足球赛。
he may be there alone, but i'm not sure.(= maybe he is there alone, but i'm not sure.) 他也许一个人在那儿，但我不能肯定。
(1) the pretty girl ______ our new classmate.
(2) ______ my father is at home.
解析：maybe是副词，意思是“也许、可能”，在句中作状语，常居于句首。而may be结构中，may是情态动词，be是动词原形，两者构成完整的谓语形式，意为“也许是，可能是”，故答案是： (1)may be (2)maybe
3、how long, how far, how often, how many, how much,
how long多久，用于提问一段时间。
-how long do you sleep every night?

how far多远，用于提问一段距离
