帮忙解答初二英语问题

1、改错 He is sure being back soon.
2、turn...up side down 如何翻译
3、Is that a good idea? I am not sure.合并成一句话 I am not sure _ _ a good idea.
多谢大家了

Answer 1

（来自一个中学英语教师的见解）
首先，be sure+(1.that从句 2.to do sth )
即：1.这句可以说“ He is sure （that也可略）he will be back soon.”
2.或者：“He is sure to be back soon.”
第二问题： turn...up side down
译为：把...翻过来（颠覆）如：turn history up side down 颠覆历史
第三问题：Is that a good idea? I am not sure.
合并成一句话：I am not sure if（是否） that is a good idea.
Is that a good idea？在合并成复合句后，作为从句——这句话必须用陈述语序，即： 变化为：that is a good idea 而且要加上引导宾语从句的连接词if或weather。
希望以上见解对你有所帮助。供参考。

Answer 2

1、He is sure to be back soon
be sure to表示确信
2、翻过来
3、I'm not sure that is a good idea.

Answer 3

3楼的回答很好，不愧是老师。不过，weather是天气的意思哦。应该是whether才对。另外，第三题两个空格，写成if/whether that's就好。

Answer 4

1.being改成to be2.倒立
3.if it's

Answer 5

1.be sure to do sth. 表示要求，意为“务必做某事；请一定做某事”
2.be sure of / about (doing) sth. 表示人对某事（物）的看法，意为“对……有把握 改成 He is sure to be back home. 或 He is sure of being back home. 意思不一样.

第二题: 把...翻过来或颠覆 如：turn history up side down 颠覆历史

第三题:I am not sure if that is a good idea.
