【例1】用所给词的适当形式填空
They’ve invited us ___(go) to their place and stay for the weekend.
【答案】to go
They’ve invited us ___(go) to their place and stay for the weekend.
【答案】to go
答案
to go
解析
本题考查固定搭配“invite sb. to do sth.”，意为“邀请某人做某事”，因此此处应填动词不定式to go。
【例2】根据汉语提示完成句子
我们班很多同学都报名参加了学校的英语演讲比赛。
Many students in our class have ___ ___ ___ the school English speech contest.
【答案】signed up for
我们班很多同学都报名参加了学校的英语演讲比赛。
Many students in our class have ___ ___ ___ the school English speech contest.
【答案】signed up for
答案
signed up for
解析
本题考查固定短语“sign up for”，意为“报名参加”。句子使用现在完成时，结构为“have/has + 动词过去分词”，sign的过去分词是signed，故填signed up for。
【例3】用所给词的适当形式填空
We ___(know) each other ever since we ___(meet) in high school.
【答案】have known; met
We ___(know) each other ever since we ___(meet) in high school.
【答案】have known; met
答案
have known; met
解析
本题考查现在完成时与一般过去时的用法。"ever since"（自从……以来）是现在完成时的标志性短语，主句需用现在完成时，结构为“have/has + 动词过去分词”，主语we为复数，故填have known；ever since引导的时间状语从句要用一般过去时，meet的过去式为met。
【例4】选词填空
after all most of all at all
She enjoys travelling, trying new foods, and ___, meeting
people from different cultures.
【答案】most of all
after all most of all at all
She enjoys travelling, trying new foods, and ___, meeting
people from different cultures.
【答案】most of all
答案
most of all
解析
首先辨析三个短语的含义：after all意为“毕竟，终究”；most of all意为“最重要的是，尤其是”，用于强调列举内容中最突出的部分；at all常用于否定句中，意为“根本”。结合句子语境，此处是强调在旅行、尝试新食物这些喜好中，最突出的是认识不同文化的人，所以应选most of all。
