老样子
三道英语语法题(有加分)
1)你只要把结构分析清楚就行,我先把中间那段宾语从句省略掉,也就是You will see (宾语从句) every time we use them.然后我单独分析宾语从句,还原成中文的语序,你应该就好看懂了:the computers you own can be ( )what great benefit 你的电脑有哪些功能.后面benefit名词要做动词解释,也就是of+名词=形容词,这里选B
2)几倍于xx的顺序应该是 几倍+as+xx,比如三倍于我的钱three times as the money i have
3)现在完成时用于以下两种情况:一是过去发生发生的动作,持续到现在,然而,从后面的but now he turns businessman investing in the stock market.,他现在已经不是work as a mechanic,所以不对.第二种情况,过去发生的动作,对现在有影响,显然在这句话的逻辑中不成立.所以这里不用现在完成时,work as a mechanic仅仅是个过去发生的动作,所以用一般过去时.
希望我的回答你有帮助
