问题内容:
老师:帮我指导如下练习题(课本第217页)
2:Of the two courses I am taking ， I find "An Introduction to Home Economics" ___
A the easiest B the easier C easy D easiest
常老师，对于比较级我想如果是"最~~"是否都以最高级est来结尾呢?比如上题目.(两者之间选择其中任何一个都应为最高级)
所以我想此题目应为A
3 We have a growing population and we are ____in need of more and more food .
A so B hence Chowever D therefore
帮助解析吧~~
6 Did you go to Plymouth or Brighton for you holiday?
We went to ____.A week in Plymouth and a week in Brighton.
A allB both
对于此题我不太明白为什么会选择B.
8 Have you been to Hangzhou yet?
Yes. I ____there twice last year.
A went B had gone C had been D have been
常老师:对于此题应为现在完成时吧以yet来判定.对于意思自然应为" 你去过杭州吗?是的 .我去年已经去了两次了"
个人认为应为 D have been.表示去年已经去过了.
对于have been与have gone的区分意思?had gone 与had been 的区分意思?
以上非常感谢常老师~~~
老师回复:
您好！2，两者之间比较只能用比较级，三者或三者以上才能用最高级。3，在句中一般用therefore. 6, 两者表示都的时候用both。8，从明确时间词“last year"来推断，应该选择答案A表过去时，另外have been表示去了又回来了，have gone表示去了还没回来。祝学习愉快！
