老師:幫我指導如下練習題(課本第217頁)
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
常老師，對于比較級我想如果是"最~~"是否都以最高級est來結尾呢?比如上題目.(兩者之間選擇其中任何一個都應為最高級)
所以我想此題目應為A
3 We have a growing population and we are ____in need of more and more food .
A so B hence Chowever D therefore
幫助解析吧~~
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
對于此題我不太明白為什么會選擇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
常老師:對于此題應為現(xiàn)在完成時吧以yet來判定.對于意思自然應為" 你去過杭州嗎?是的 .我去年已經(jīng)去了兩次了"
個人認為應為 D have been.表示去年已經(jīng)去過了.
對于have been與have gone的區(qū)分意思?had gone 與had been 的區(qū)分意思?
以上非常感謝常老師~~~

老師回復:

您好！2，兩者之間比較只能用比較級，三者或三者以上才能用最高級。3，在句中一般用therefore. 6, 兩者表示都的時候用both。8，從明確時間詞“l(fā)ast year"來推斷，應該選擇答案A表過去時，另外have been表示去了又回來了，have gone表示去了還沒回來。祝學習愉快！
