一、单项选择。
1. The museum is open from 9 a. m. 10 p. m. at weekends. （）

A.and
B.to
C.with
D.along

B

本题考查固定搭配from...to...，该搭配意为“从……到……”，用于表述时间范围，符合句子表达博物馆周末开放时段的语义，其余选项均不符合该用法。

2. For students, doing housework is part of their school tasks to learn life .
()

A.skills
B.cultures
C.problems
D.changes

A

先明确各选项含义：A. skills 技能；B. cultures 文化；C. problems 问题；D. changes 改变。结合句子语境“对学生来说，做家务是他们学校任务的一部分，用来学习生活______”，life skills（生活技能）是符合逻辑的常用表达，其余选项语义不符合句意。

3. —I think washing hands before eating is good for our health. ()
—Yes, I with you!

A.understand
B.fill
C.agree
D.promise

C

根据对话语境，答句的Yes表明认同对方的观点，固定搭配agree with sb. 意为“同意某人的看法”，A选项understand（理解）、B选项fill（填充）、D选项promise（承诺）均不符合句意和搭配要求，只有C项符合。

4. We planned to go to Japan, but we went to Thailand instead. （）

A.still
B.finally
C.heavily
D.certainly

B

辨析各选项词义：A. still 意为仍然；B. finally 意为最终、最后；C. heavily 意为猛烈地、大量地；D. certainly 意为当然。结合句子“我们原本计划去日本，但最后我们反而去了泰国”的语境，只有finally符合语义逻辑。

5. —Do you know the saying “A thousand-mile journey（行程）begins with the first ______ ”?
（）
—Yes. It's a famous Chinese saying by Laozi.

A.experience

D

该句对应老子的名言“千里之行，始于足下”，对应的标准英文表达为"A thousand-mile journey begins with the first step"。选项A意为经验，B意为赛跑，C意为错误，只有D项step（脚步）符合该谚语的含义。
