我不会了。
考查祈使句。
doesn’t现在时三单形式的助动词；don’t 现在时动词原形助动词；isn’t不是；won’t将不会。
根据句意及句子结构可知，这里是一个祈使句，应该以动词原形开头，而且表达否定的意思，应在句首加don’t，故选B。
【点睛】英语中祈使句是以动词原形开头的句子，而否定形式则是以don’t开头的句子，记住结构，做题就很容易。
解析：D【解析】【分析】【详解】句意：当你一个人的时候照顾好你自己，否则你的父母会为你担心的。
Taking动名词；To take动词不定式；Taken过去分词；Take动词原形。
这句话使用的句型是祈使句+or+简单句，故用动词原形开头，选D。
3．A解析：A【解析】【详解】句意：请不要忘记把你的作业带去学校。
根据句意“不要忘记把你的作业带去学校”可知使用否定祈使句，结构为don't+动词原形。
please用在祈使句中可以表示一种客气的语气，故答案选A。
4．B解析：B【解析】【详解】句意：麦克，不要吵闹，你父亲正在睡觉。
考查祈使句。
A. not 不，没有；B. don’t 不，没有；C. won’t 将不会；D. can’t 不能，不会。
A 选项为否定词；B选项为助动词，后面要接动词；C选项为助动词，将来时表将来；D选项为情态动词，表否定推测。
根据否定祈使句用法，应用助动词don’t + 动词原形结构。
A、C、D均不符合，故应选B。
5．B解析：B【解析】【详解】句意：不要害怕犯错误。
我们可以从错误中学习。
考查祈使句。
本句是否定祈使句，用“Don’t +祈使句”结构；祈使句的动词用原形，根据句意结构，可知选B。
6．C解析：C【解析】【详解】句意：每天多锻炼，你就会比之前更强壮。
考查连词。
A. but“但是”，表转折；B. for“为了”；C. and“并且；然后”，表顺承；D. or“或者”，表选择。
根据固定句式“祈使句+and+表顺承的句子”，表示“做……，然后就……”，故选7．C解析：C【解析】【详解】句意：——我们需要更多的办公用品。
——好的。
我们列个单子吧。
根据句意理解及句中的let's可知，英语中让某人做某事是let sb do sth，let后面接动词原形，所以选择C。
8．A解析：A【解析】【详解】句意：只是直走，然后向左拐。
本题考查祈使句。
go是动词原形；to go是动词不定式；going是现在分词。
此处是祈使句，谓语用动词原形，故选A。
9．C解析：C【解析】【详解】句意：-请拼一下。
-G-R-E-E-N，绿色。
