(
) 2.Turn
the lights.
A. off
B. close
C. of

答案

A

解析

本题考查固定短语搭配。“turn off”是固定短语,意为“关掉(电器类物品)”,符合“关灯”的表达;“close”通常用于关闭门窗等实体物品;“of”是介词,不能与“turn”搭配构成该语义。

) 3.We can
the floor.
A. sweep
B. cook
C. do

答案

A

解析

这道题考查固定短语搭配。“sweep the floor”是固定表达,意为“扫地”,符合题意;“cook”意为“烹饪”,不能和“floor”搭配;“do”通常和“housework”等词搭配构成短语,不与“floor”直接搭配,所以选A。
(
) 4.
eat in class.
A. Not
B. Don't
C. No

答案

B

解析

本题考查祈使句的否定形式。祈使句的否定结构为“Don't + 动词原形”,用于表达禁止做某事。句中eat为动词原形,需用Don't引导否定祈使句。A选项Not不能直接接动词原形构成否定祈使句;C选项No后常接名词或动名词,不符合本题用法。
(
) 5.I am
duty today.
A. at
B. in
C. on

答案

C

解析

本题考查固定短语搭配。“on duty”是固定表达,意为“值日、值班”,符合句子语境,at和in无法与duty构成该固定搭配。
