参考答案
(1) 询问某人的职业
1. 答案:What does he do?He is a baker. He makes bread.
解析:主语 he 是第三人称单数,特殊疑问句用助动词 does;be 动词用 is;实义动词 make 变第三人称单数形式 makes。
2.答案:-What do they do? -They are nurses. They help sick people.
解析:主语 they 是复数,特殊疑问句用助动词 do;be 动词用 are;实义动词 help 用原形。
3.答案:-What does Amy do? -She is a vet. She saves cats and dogs.
解析:主语 Amy 是第三人称单数,特殊疑问句用助动词 does;be 动词用 is;实义动词 save 变第三人称单数形式 saves。
(2) 情态动词 should 的用法
一、
1.答案:-What should he do?-He should have some water.
解析:情态动词 should 后面跟动词原形,所以 do 和 have 都用原形。
2.答案:The boy shouldn't eat or drink after meals. He is too fat.
解析:根据 “他太胖了” 的语境,这里表达 “不应该”,所以用 should 的否定形式 shouldn't。
3. 答案:Should her sister brush her teeth?
解析:情态动词 should 引导一般疑问句时,直接提前到句首,后面跟动词原形 brush。
4. 答案:They shouldn't shout in class.
解析:课堂上不能大喊大叫,所以用 should 的否定形式 shouldn't。
二、
1.答案:B
解析:根据 “Bobby 十岁” 和 “在繁忙的马路上骑车” 的语境,这里表达 “不应该”,选 shouldn't。
2. 答案:A
