2道英语填空题
1.If Mary does not clean her teeth every day,she will have toothache.
____ Mary______her teeth every day,
she will have toothache
2.If you are strict in your study,
you will catch up with your classmates
_____strict in your study,
_____you will catch up with your classmates
有适当难度,尽力而为吧!请讲清理由,
注意第一题没给明动词clean!你们会不?
第一句是原句,第2句是改句,这都不懂?
而且是 she will have toothache
所以不可能是unless
1.Unless (如果不=if not) does
if unless 引导的是调价状语从句 主将从现 主语是Mary 单数名词 谓语动词用单数
2.Be and
strict是形容词前面用be 在开头要大写
句式就是:祈使句+and或or+一般将来时的句子
