A.at B.of C.for D.on

答案是twice as likely 请教我这种频率+as、倍数+as的题目该怎麼判断顺序等等

3.He ____ as a mechanic for 10 years but now he turns businessman investing in the stock market.
为什麽不是had worked 而是 worked？

老样子 每道题都仔细分析一下 答得好加分 谢谢

Answer 1

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
