不是定语从句么 怎么会选A?后面修饰scenes啊
8.We're just trying to teach a point___ both sades will sit down together and talk .
A,where B,that
选A.
2.句不能还原成He's got himself into a dangerous situation.He is likely to lose control over the plane.所以就可以用that 或者which引导定语从句啦?
3.This is the reason (that) he explained at the meeting for his carelessness in his work.怎么翻译?总觉得用+why也可以.如果非要用why怎么改?
4.one作代词,指代a moment,在句中作an unforgettable moment的同位语.what不能引导定语从句,只可引导名词性从句 (好矛盾= = 到底是同位语还是定语从句?明明是宾语从句啊)
7.同位语从句 that充当scenes的同位语 不可省 (答案选in which错了?)

1.你的答案错了吧.我在网上查了大概十个网页,都是选择has been.
2.7.8.三题放在一起看,先行词分别为situation,scenes,point,还有一个词case,这些词作为定语从句的先行词的时候,引导词通常用where,相当于in which. 引导定语从句的词不仅仅是that,which,who,whom这些关系代词,还有关系副词where, when,why.关系代词在从句中通常充当主语或者宾语的成分,用看来最复杂的第七题举例吧,从句中主语为people,用了被动结构,不缺主语宾语,A选项有介词in,介词后要接宾语的,宾语的成分就由which这个关系代词担当了,which指代先行词scenes,所以从句实为people were eaten by the tiger in the scenes.这里也可以用where,相当于in which,另外两题就选择了where.这句话意为：很多看了那电影的人都不敢去森林,他们会想到人们被老虎吃了的场景.
3.先变成陈述句：this is the reason he explained at the meeting for his carelessness in his work.
这里he explained 是省略了关系代词的定语从句,因为关系代词在从句中做explained的宾语.意为他说明的这个原因,就是他说出来的这个原因,可以把explain理解为give.整句话意为：这就是他在会议上说明的工作失误的原因?
如果选择why he explained意为他为什么会解释的原因,这个意思就比较牵强了.
the reason why he explained was that he didn't want to be misunderstood.
再看我这个句子对比一下：他为什么解释的原因是他不想被误会.
4.one这里用作同位语,指代moment.这句话应为：one that i will always treasure 省略了关系代词,因为它在从句中充当treasure的宾语.
至于what,首先前边有个逗号,那就不能用what了,what引导名词性从句前边一般不加逗号.其次这不是名词性从句,因为既然是名词性从句就要担当名词的成分,比如主宾表的成分,可是主句主语表语都有了.
5.I'll tell you more about later,这根本不是完整的一句话,不可能是时间状语从句,这个句子介词about后边缺宾语,只能选择which充当宾语的成分,引导非限制性定语从句.
6.我查到的答案应为A.which指代先行词nine months,所以of which the sailing time was 226 days应为：the sailing time was 226 days of the nine months. of表示从属关系,指上文nine months之中的海上行程是226天.
