I think ( ) very important to learn
I think ( ) very important to learn ... I think ( ) very important to learn a foreign language. 括号中是用 it 还是用 it's？
两者均可. 无论用it 还是it's都可以,意思也没有什么区别,但语法结构却完全不同: I think (it ) very important to learn a foreign language. 代词it是动词think的宾语(代替的是to learn a foreign language),very important 是对宾语的补充说明,是宾补.整句是个简单句. I think (it's ) very important to learn a foreign language. "it's very important to learn a foreign language"整句做宾语,是宾语从句.整句是符合句.
应该是 it's 因为在有 i think , i suppose 等引导的句子中，i think , i suppose 可视为插入语，后面的句子可按正常语法规则进行
答案应该是 it's
要在这句话中把它翻译成“它是”。"it"在这里用作代词，代指后面的"a foreign language" 加上"'s"后，这句话中才有动词。"to"后的"learn"也是动词，但在这里它与后面的"a foreign language"连成了短语，因而不能算作是这句话中的动词。所以答案应该是it's.
understand?
答：选B， 非限定性定语从句，引导词指物时用which，指人时用who，不能用that,而i think 是插入语，紧跟主语后面．详情>>
