陈述部分含宾语从句时,疑问部分通常与主句一致.但当主句的谓语动词是think,believe,suppose等且主语是I ,we时,即:I / We think (believe)(suppose) + 宾从,则附加问句应与从句一致.而本句,翻译为“我认为他本不可能在上个星期的期中考试中发挥得好”是表猜测的句子,意思是“他做到了”.表推测的情态动词的附加疑问句,其附加疑问句与情态动词后的动词一致.而本句是明显的过去猜测的句子,由last week也可推知是过去的动作,所以用did

既然选NO你理解了,那么就讲前面那个空BOY的意思是:我想TOM在上星期的期中测验没有做的很好吧,有吗?那么在附属疑问的时候,应该加上did he 而非 could he表示他是否做了。。。而非他能否做。。。
could have done,must have done出现在句子中时,如果有明确的过去时间,它的反义疑问句用要did,如果没有,那么反义疑问句就用have这题里有个 last week的过去时间,所以用did
楼上是错的could have done sth.是一个特定搭配看例句:1.I didn't go to the cinema yesterday. I could have gone there but my sister was ill.I had to stay at home and take care of her. 表示"本来可以做某事...
I don`t suppose我不认为后面应该和从句保持一致Jim could have若是She\He doesn`t suppose则与主句保持一致

2010江苏高考化学理综第十四题D选项。下有详细疑问。我看其他解析都解释说a1+a2=1,为什么?同一化学正逆反应方向的转化率有什么关系?请解释一下。
你把题目补充一下把 就是具体的那道题
记住,同一化学正逆反应方向的转化率相加为1,这是因为在正反应,假如反应了A(我随便给个数字)那么相应的逆反应就只能达到1—A,也可以从逆反应方向看,都是一样的。明白么?
在相同条件下,同一化学正逆反应到达的最后状态相同,因此以下如meteorboy2009 所说,故a1+a2=1

  When you read a story in English, do you read it for the story or  
for the English? This is a 1 that is not so foolish 2 it may seem. For  
I 3 that many students of English 4 far more attention to the story  
than to the English. They read and 5 and for a long time 6 remember  
the story, but do not care to study the 7 of words and 8 in it. For  
instance, they care for the memory of 9 the mystery (神秘) in the  
story is solved, but do not remember a 10 sentence in the story and  
cannot 11 what preposition is used before or after a certain 12 in  
the speech of a 13 character.  
   Of course, it is all right to read and enjoy and 14 a story, and  
so 15 as one wants to 16 the story only, one need not bother (费心)  
about the language. But the case is quite different with a 17 of  
English. I mean a student of English is different from a student of  
stories or 18 is called the general reader.

negatively (负面) it will help you to avoid many errors and faults in  
expression. Incidentally I have found from 24 that intelligent  
copying is a help to 25 by heart.

第一道题选D第二道B&&& 有疑问的是第二道 为什么A不能选呢!南方都是低山丘陵怎么会地势起伏大呢
第二道选B丘陵为世界五大陆地基本地形之一,是指地球表面形态起伏和缓,绝对高度在500米以内 ,相对高度不超过200米.南方低山丘陵地势有起伏,地势起伏较大(比起平原来说较大),所以易造成水土流失.不能选A

第二题,题干中问的是,“不包括的是”,南方虽以低山丘陵为主,但对于形成水土流失来说,这种地势起伏足够大。
