_______________________________________一、单项选择
1.答案：B
-解析：根据答语“Yes, you can.”可知，问句是用Can引导的一般疑问句，表示请求许可，意为“我可以再吃些面包吗？” ，Must（必须）、Need（需要）、Should（应该）均不符合语境。
2.答案：A
-解析：本句是there be句型，表示“有” ，排除C、D选项；meat是不可数名词，所以be动词用is ，are用于复数名词前。
3.答案：B
-解析：vegetables是可数名词复数，sweet food是不可数名词。many修饰可数名词复数；a few修饰可数名词复数；much修饰不可数名词；a little修饰不可数名词；a lot of既可以修饰可数名词复数，也可以修饰不可数名词。为了保持健康，应该多吃蔬菜、少吃甜食，所以选B ，表示“许多蔬菜和一点甜食”。
4.答案：B
-解析：根据“It's dangerous.”可知，在马路上踢足球是危险的，所以是禁止的行为。mustn't表示“禁止” ；must意为“必须” ；can意为“能，可以” ；needn't意为“不必” 。
5.答案：B
-解析：usually表明句子时态是一般现在时，主语Mike是第三人称单数，谓语动词finish要用第三人称单数形式finishes 。A选项是动词原形；C选项是现在分词；D选项是动词不定式，均不符合要求。
6.答案：C
-解析：like doing sth.表示“喜欢做某事” ，是固定搭配，所以两个空都用动词的 -ing形式eating 。
7.答案：B
-解析：need作实义动词时，常用结构为need to do sth. ，表示“需要做某事” ，所以选B 。A选项是动词原形；C选项是现在分词；D选项是第三人称单数形式，均不正确。
8.答案：C
-解析：句中cross是动词，需要用副词来修饰，表示“安全地过马路” 。safe是形容词，意为“安全的” ；safety是名词，意为“安全” ；safely是副词，意为“安全地” ；save是动词，意为“拯救，节约” 。
9.答案：D
-解析：students是可数名词复数，a lot不能直接修饰名词；much修饰不可数名词；a little修饰不可数名词；lots of既可以修饰可数名词复数，也可以修饰不可数名词，相当于a lot of ，所以选D 。
10.答案：C
-解析：bread是不可数名词，“两片面包”的表达是two pieces of bread ，piece是可数名词，前面有two修饰时要用复数形式pieces ，bread没有复数形式。
11.答案：B
-解析：rice是不可数名词，a few修饰可数名词复数；a little修饰不可数名词；many修饰可数名词复数；lot of表达错误，应为lots of或a lot of 。根据“she wants to lose weight”可知她吃的米饭少，所以用a little 。
12.答案：B
-解析：红灯亮时，不可以过马路。can't表示“不能，不可以” ；can表示“能，可以” ；must表示“必须” ；need表示“需要” 。
13.答案：B
-解析：在一般疑问句和否定句中，通常用any表示“一些” ，some常用于肯定句。所以问句用any ，答句也用any 。
14.答案：B
-解析：walks是动词，需要用副词修饰。slow是形容词，意为“慢的” ；slowly是副词，意为“慢地” ；quick是形容词，意为“快的” ；quickly是副词，意为“快地” 。根据“We should wait for him.”可知老人走得慢，所以选B 。
15.答案：B
-解析：always表明句子时态是一般现在时，主语My mother是第三人称单数，谓语动词put要用第三人称单数形式puts 。A选项是动词原形；C选项是现在分词；D选项是动词不定式，均不符合。
二、用所给词的适当形式填空
1.答案：has
-解析：句子时态是一般现在时，主语Mike是第三人称单数，have要用第三人称单数形式has 。
2.答案：follow
-解析：must是情态动词，后面接动词原形，所以用follow 。
3.答案：fast
-解析：fast既可以作形容词，也可以作副词，这里修饰动词running ，用副词fast ，表示“跑得快” 。
4.答案：is
-解析：cola是不可数名词，在there be句型中，be动词用is 。
5.答案：to go
-解析：need to do sth.表示“需要做某事” ，所以用to go 。
6.答案：cola
-解析：cola是不可数名词，没有复数形式，所以直接用cola 。
7.答案：watches
-解析：often表明句子时态是一般现在时，主语My father是第三人称单数，watch要用第三人称单数形式watches 。
8.答案：twice
-解析：twice a day表示“一天两次” ，这里用twice表示次数。
9.答案：is
-解析：Eating too much meat是动名词短语作主语，看作一个整体，谓语动词用单数形式，所以be动词用is 。
10.答案：loudly
-解析：talk是动词，用副词loudly修饰，表示“大声地谈论” 。
11.答案：sweet
-解析：sweet在这里作形容词，修饰名词food ，表示“甜的食物” 。
12.答案：to wash
-解析：need to do sth.表示“需要做某事” ，所以用to wash 。
13.答案：puts
-解析：always表明句子时态是一般现在时，主语Yang Ling是第三人称单数，put要用第三人称单数形式puts 。
14.答案：play
-解析：mustn't是情态动词，后面接动词原形，所以用play 。
15.答案：any
-解析：在否定句中，用any表示“一些” ，some常用于肯定句，所以把some改为any 。
16.答案：to drink
-解析：need to do sth.表示“需要做某事” ，所以用to drink 。
17.答案：eating
-解析：like doing sth.表示“喜欢做某事” ，所以用eating 。

21.答案：health
-解析：your是形容词性物主代词，后面接名词，healthy是形容词，其名词形式是health ，be bad for your health表示“对你的健康有害” 。
三、按要求改写句子

-解析：对“a lot of bread”提问，即询问“你早餐吃什么？” ，用疑问词What 。
2.答案：Does; like
-解析：句子时态是一般现在时，主语She是第三人称单数，变一般疑问句要借助助动词Does ，动词likes变回原形like 。
3.答案：isn't any
-解析：There be句型的否定句是在be动词后加not ，is not缩写为isn't ；some用于肯定句，否定句中要把some改为any 。
4.答案：mustn't
-解析：must的否定形式是mustn't ，表示“禁止” ，原句改为否定句为“你禁止过马路” 。

-解析：句子时态是一般现在时，主语Mike是第三人称单数，变一般疑问句要借助助动词Does ，动词eats变回原形eat ；肯定回答用“Yes, 主语+助动词.” ，所以是Yes, he does.
8.答案：are many
