2.【2018·北京】5. She and her family bicycle to work, _________ helps them keep fit.
A. which
B. who
C. as
D. that
【答案】A
【解析】考查非限制性定语从句。句意：她和家人骑自行车去上班，这有助于她们保持健康。“____ helps them keep fit”是非限制性定语从句，该从句修饰整个主句，引导词在从句中做主语，故该从句应用关系代词which引导。A选项正确。
点睛：非限制性定语从句即可修饰主句的一部分，也可以修饰整个主句。其引导词的选择和限制性定语从句的判断规则一致，即：第一、找准先行词；第二、看先行词在定语从句中所作的成分。需要注意的是，that不能引导非限制性定语从句。
3.【2018·北京】8. In any unsafe situation, simply _________ the button and a highly-trained agent will get you the help you need.

B. to press
C. pressing
D. pressed
【答案】A
【解析】考查祈使句。句意：在任何不安全的情况下，仅仅摁一下这个按钮，一个训练有素的特工就会使你得到你需要的帮助。and是连词，连接并列结构，and后面是一个句子，那么，前面也应是句子，选项中只有动词原形可以构成祈使句，其余的都是非谓语动词，无法构成句子。故A选项正确。
点睛：祈使句+and/or+陈述句是一种常见结构。当前后两部分间为承接关系时，用and；前后意思为相反关系时，用or。该句式中的陈述句部分常用一般将来时态。
4.【2018·北京】11. Without his support, we wouldn’t be _________ we are now.
A. how
B. when
C. where
D. why
【答案】C

点睛：表语从句是指一个句子充当表语，通俗的说就是系动词be后面接一个句子。连接表语从句的连接词有that，what，who，when，where，which，why，whether，how等。
5.【2018·北京】15. This is _________ my father has taught me—to always face difficulties and hope for the best.

6.【2018·天津】14. It was only when the car pulled up in front of our house ___________we saw Lily in the passenger seat.
A. which
B. that
C. when
D. where
【答案】B
【解析】考查强调句。句意：只有当汽车在我们房子前停下来我们才看到在乘客位置的莉莉。这里考查强调句，强调句型结构为：It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。本题强调时间状语only when the car pulled up in front of our house。故选B。
点睛：本题考查强调句，要求有学生掌握好强调句的常用句型以及相关知识的能力。分析句子时首先要看清楚结构，It is / was…开头而后面跟句子时就要看它是不是强调句了。强调句有一个特点：拿掉It was/is…that…后不影响整个句子的完整性，则是强调句。判断完是不是强调句后再根据强调的部分是人还是物来选择连接词that或者是who。
7.【2018·天津】9. The gold medal will be awarded ___________to wins the first place in the bicycle race.
