要中考了,《中考指导书》上的几道初三英语题,
1.Having too many sweet snacks b_____ meals is not a good habit.
答案是between,但是可不可以填before呢?between一定要和and连用么?
2.Aunt Wang is over 80 years old and she needs _____ housework.
help with,我想这里不是应该是被动么?need to 不就成主动了么?
3.-Could you speak English at that time?-Yes I _____.
答案是can,这是过去难道不应该用could吗?
还有两题不是指导书上的也想问一问……
1.You ___ to the meeting tomorrow if you have something important to do.
这里应该用 needn't to come 还是 needn't come?为什么?
2.-Why does Miss Wang look so worried?- Because she wonders ____.
这里应该用what has happened to the boy 还是 whether the boy had been hurt?为什么?
问题有点多,我们老师要么不讲要么讲的不清楚,实在想不明白这几题,

答案

第一题到底用before还是between要看你如何理解句意,between不一定要和and连用,只是大多数时要和and连用
第二题是她需要帮忙,用中文就可以想想,难道她需要被帮忙么?翻译不过来的
第三题不是过去式,问句中的Could是表示礼貌的、宛转的问法,而且正在对话,怎么能用could?就算问的是过去式,但会讲英语是一种能力,不讲时间地点是否改变,总不能说那时我会讲英语,现在不会了吧?
1.用needn’t come (need的否定式就是needn’t,从来就没有needn‘t to 的用法）
2.用whether the boy had been hurt（从句要用陈述语序,不能用疑问句式）
