Q1对错判断
判断下面句子里 cover 的用法是否正确:
The health insurance plan is covering all types of medical treatment.
✓ 正确版本
The health insurance plan covers all types of medical treatment.
这份健康保险承保所有类型的医疗。
cover 作「承保/涵盖」义是状态动词,描述固定的保障范围,通常用一般现在时,不用现在进行时。
Q2义项辨析
下面哪个句子里 cover 的用法和其他三个最不同?
A
The documentary covers events from the 1960s to the present day.
B
Can you cover for me on Tuesday? I have a doctor's appointment.
C

D

A/C/D 中 cover 均表示「涵盖/包括/承保」;B 中 cover for sb.(代某人值班/打掩护)是独立的固定短语义项。
Q3翻译应用
用 cover 翻译下面句子(可参考 writing_upgrade 字段):
本报告将涵盖数字技术对劳动力市场的影响、相关政策挑战以及可能的解决方案。
This report will cover the impact of digital technology on the labour market, the associated policy challenges, and potential solutions.
关键搭配:will cover the impact
will cover 是引言段宣告文章框架的书面标准表达,比 will discuss/talk about 更简洁正式,清晰列出文章涵盖内容。
