新概念英语2 里面一些问题。有追加悬赏⋯⋯
p105 exercise b 第2题.我凌乱了- -should have to have 也不懂?我觉得不能又不知道为什么。p30 a exercise5!改为what 引导的感叹句怎么改4。and which side of the dish ——you(live)&#8943。this is the hotel at —— we are staying。1.请问had he got&#8943。p136 exercise 2;&#8943。p38 exercise 10;请讲的详细一点好吗⋯8。p135 composition 里面的 she has driven a car for many years but she says that women drivers (do not deserve)(are not worth)their bad reputation.had not been for 是什么意思⋯我虚拟语气还不是很懂&#8943。要求填带way的短语是填 in this way 么?要求用括号中动词的正确形式填空。as soon ⋯⋯是什么用法呐&#8943、介词的位置能不能换、12题;⋯⋯&#8943,还是什么⋯7;那么我会给追加悬赏30~50分&#8943。he is causing a lot of trouble.(同义句)__No__ __sooner__ __had__ he got on the bus
__than__ it began to move,这个句子是什么时态都不懂了⋯⋯9、4题
he is the only student ——understands english well。the ship would have sunk if it __had not been__ (not be) for the captain。可是我这个句子意思都不懂&#8943。3,I would __come__(come)2。If I __should have to have__(have) time tomorrow。p128 exercise b 的倒数第二行。应该选哪个。children get —— during the holidays,it began to move。还有练习册的&#8943。要求在需要的地方填上who which that 或whose我木有练习解答什么的请见谅;5。请讲明为什么顺便说一下涉及哪个知识点好么。send her away or she will cause problemmake up your mind
这两个句子的宾语?这两个词组什么意思呐6
this is the hotel (at which)或者(where)we are staying1:你以那种食品为食。我也还是个学生,living on 是以. 3,缺少主语填who.我不清楚2.我不清楚6。我先有点事.4‘are living’意思是.,所以可以改为make your mind up,at which =where ,希望上面的对你有帮助哈.为食的意思5;因为make up your mind
是祈使句,所以句子可以改为send away her or she will cause problem,明天再继续回答看看.是宾语从句,也可看成stay at 固定词组.What a lot of trouble he is causing.,词组make up可以延伸为make something up 或make up something. 因为send away是固定词组,谢谢

1.in the way或者in their way ,意思就是假期不太顺,受阻的意思
2。send her 应该因为her 是人称代词,在使用的时候只能放在动词之后,给个列子talk about it,put it down.但若是具体的事物放在介词后或者动词后都可以,但第二个词组make up one's mind 是固定搭配,不能调换位置。
3,What a lot of trouble he is causing!
7.倒装句型。as soon as 等于 no sooner than 都表示一........就....... 举个例子As soon as he got home, his phone rang.他一到家,他的电话就想起来了。也可以变成No sooner had he got home than his phone rang.No sooner 之后用完成时时态助动词还必须提前,例子No sooner had he turned on the computer than he played the games, 动词turn 变成had turned 然后had提到主语...
