答案略

2. 选词填空。
with little must for by mustn't up few in
(1) Nancy is crossing the road her classmates.
(2) The little boy walked and woke his mother .
(3) You litter in the park and the zoo.
(4) We put our books and pens order.
(5) She was not hungry. She only ate a bread.

(1) with
(2) up; up
(3) mustn't
(4) must; in
(5) little

(1) “Nancy is crossing the road... her classmates.” 表示南希和她的同学一起过马路，“with” 有 “和……一起” 的意思，所以此处填 “with”。
(2) “The little boy walked... and woke his mother...” ，walk up 有 “走近，走向” 的意思，wake sb. up 是 “叫醒某人” 的固定搭配，所以依次填 “up”，“up”。
(3) “You... litter in the park and the zoo.” 在公园和动物园乱扔垃圾是不被允许的，“mustn't” 表示 “禁止，不允许”，所以填 “mustn't”。
(4) “We... put our books and pens... order.” put... in order 是 “把……整理整齐” 的固定搭配，“must” 表示 “必须”，所以依次填 “must”，“in”。
(5) “She was not hungry. She only ate a... bread.” 因为不饿，所以只吃了一点面包，“a little” 表示 “一点”，修饰不可数名词 bread，“few” 和 “little” 单独使用表示否定，“a few” 修饰可数名词，所以填 “little”。

1. 选择填空。
()(1) —What they mean? —They mean you run or play here.

A.does; must
B.does; mustn't
C.do; must
D.do; mustn't

D

问句中主语为they，是复数，一般现在时的特殊疑问句中助动词应用do；根据句意“它们的意思是你不能在这里跑或玩耍”，可知第二个空应为mustn't，表示禁止。

()(2) —Why the bus stop? —There was the red light.

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

C

根据答语“There was the red light.”可知问句时态为一般过去时，问句中主语you后缺少助动词，一般过去时中助动词用did。所以选C。

()(3) He didn't the traffic lights. He the road quickly.

A.find; cross
B.found; cross
C.find; crossed
D.found; crossed

C

第一空，助动词didn't后接动词原形，用find；第二空，句子时态为一般过去时，谓语动词用过去式crossed。

()(4) — you go to school early every morning? —Yes, I do.

A.Do
B.Does
C.Are
D.Did

A

根据答句“Yes, I do.”可知，问句是由助动词do引导的一般疑问句。主语是you，第二人称，所以助动词用do。A选项Do符合；B选项Does用于第三人称单数；C选项Are是be动词，答句需用be动词回答，不符合；D选项Did是过去式，答句也应用过去式，不符合。

()(5) —Does Yang Ling often vegetables?
—Yes, she likes tomatoes very much.

A.eat; eats
B.eat; eating
C.eats; eating
D.eats; eats

B

问句中一般现在时的一般疑问句，借助助动词does后，主语后面的动词用原形，所以第一个空填eat；答句中“like doing sth.”表示喜欢做某事，是固定搭配，所以第二个空填eating。
