区别两个句子的He's中的S是HAS 还是IS
he's up to date with the European market
He's with the product development department
UP TO DATE 是个固定词组啊 也可以做BE UP TO用?还有就是这两个句子你给翻译下中文意思 句子有没有错误 完整句子 1.He was promoted to chief of the overseas sales department last year,so he's up to date with the European market 2.He's with the product development department.He knows more about this product than anyone else 两个句子的S都是 IS?
is ==>be up to
is 根据句义判断,is apartment,
with……短语作伴随
区别:可以根据句子意思判断出是“is”,"has"(动词或助动词)
has+done or has+n.
