2026年苏学精品六年级英语下册第20页答案
一、选择题。
(
) 1. — Can I go fishing with you, Dad?
— No, you
. You
stay at home and do your homework first.
A. won’t, may
B. can’t, must
C. shouldn’t, ought
D. needn’t, should

答案

B

解析

第一空,问句用Can提问,否定回答用can't;第二空,根据语境“必须先待在家做作业”,must表示“必须”,符合六年级can的章节内容。
(
) 2. — Do you know whose dictionary it is? — It
be Li Wei’s. His name is on it.

A.can
B.must
C.should
D.need

答案

B

解析

根据题意“His name is on it.”可知这是确定情况的依据,在情态动词中“must”表示肯定推测,意为“一定,肯定”,符合题目语境。而“can”表示推测时多用于否定句或疑问句;“should”表示应该;“need”表示需要,均不符合题意。
(
) 3. — I can’t stop smoking, doctor. — For your health, I’m afraid you
.

A.can
B.can’t
C.must
D.mustn’t

答案

C

解析

根据对话情境,医生为了患者健康,语气应是建议必须戒烟。can表示“能”,can't表示“不能”,must表示“必须”,mustn't表示“禁止”。此处用must符合语境。
(
) 4. — Is Mr Brown driving here? — I’m not sure. He
come by train.

A.may
B.shall
C.need
D.must

答案

A

解析

根据题意,“— 布朗先生开车来这里吗? — 我不确定。他_______ 乘火车来。” 需要选择一个表示推测的情态动词。may 表示可能性,可以用于不确定的情况;shall 常用于提出建议或表示将来,一般不用于表示推测;need 表示需要,不符合题意;must 表示必须或肯定推测,语气较强,但题中是不确定的情况,因此选择 may。
二、用 can 或 could 的相关形式填空。
1. He
swim and I
sing.
2. She
read and draw now, but she
write five years ago.
3. Liu Tao
play basketball when he was a child.
4. I
use the mobile phone until I was fifteen years old.
5. — What could you do three years ago? — We
ride a bike to school.

答案

1. can, can 2. can, couldn't 3. could 4. couldn't 5. could

解析

1. 句子描述一般能力,用can。2. 前半句now表现在,用can;后半句five years ago表过去,否定用couldn't。3. when he was a child表过去,用could。4. until I was fifteen表过去不能,用couldn't。5. 问句用could,答句也用could。
