用所给的单词的适当形式填空 she can__(swim) now.what __your brother __(do)at home now?
答
swim, is, doing
答
she can swim now. what is your brother doing at home now?
can 是情态动词,后面要跟动词原形,所以直接 用swim;
根据句子(what __your brother __(do)at home now?)结尾处的副词now 以及提示词do 我们可以判断词句该是现在进行时态,所以该句应该是是what is your brother doing at home now?
因为 your brother 是第三人称单数,所以前面用 is
答
swim 原因:can 是情态动词,虽然是现在时,但是情态动词后是用动词原型,所以直接填swim
is; doing
