3.选B。可以吗。“没问题” 4.选C可以吗。 这个句子的结构我还不是不太明白。请再深入讲讲。
7. A和B有什么区别 10.而’‘waste of money’‘意为’‘浪费金钱’‘， 为什么呀，中间这个of的意思不再是“的”了吗 11.能写him 吗。。我一直想着好多词后面都要用宾格，所以我写了him 12.这句话什么意思。前面否定了，为什么还说很满。
第3题：虽然选B也符合逻辑，但在做题的时候，如果碰到这种模棱两可的情况，我们就要选最符合条件和情境的选项。
第4题：把C答案代进去，后面的从句就变成了did he bought the computer(他买了电脑吗），而前面的特殊疑问词是where,是对地点的提问，再者宾语从句要用陈述语序，而did he bought the computer是疑问语序，所以不能选C。宾语从句是重难点，一定要耐心学。
关于宾语从句：
定义：置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。有些形容词（afraid,sure,glad等）之后也可以带宾语从句。例如第4题‘’Where do you think he bought the computer‘’中think是动词，后面的从句起到宾语的作用，而这个从句就是think想说明的对象。
引导词有：
连词：that (that 常可省略),whether, if
代词：who, whose, what ,which
副词：when ,where, how, why 等。
宾语从句的语序是陈述句语序即：连接代词/副词+主语+谓语+其他成分。例句如下：
I don’t know what they are looking for.
Could you tell me when the train will leave?
Can you imagine what kind of man he is?
最重要的是要记住宾语从句的语序必须是陈述语序。
请继续追问，因为我的字数已经超过了限定范围，在你追问之后我会把后面的解释补充进来。
7. A和B有什么区别 10.而’‘waste of money’‘意为’‘浪费金钱’‘， 为什么呀，中间这个of的意思不再是“的”了吗 11.能写him 吗。。我一直想着好多词后面都要用宾格，所以我写了him 12.这句话什么意思。前面否定了，为什么还说很满。 大侠，，有Q吗。。以后想问你一些问题。
追答第7题：检查一下你有没有把A选项打错，A选项是‘’what the have learned''这是一个病句，应改为‘’what we have learn'',''what''和''have learned''之间至少有一个表示人物的名称。
第10题：of作介词时有‘’关于；属于…的；由…制成‘’的意思，在这里意为‘’有关‘’，即‘’关于金钱的浪费‘’。学英语不能过于咬文嚼字，你只需记住，这是一个词组。
第11题：him是宾格，放在动词后面，例如：I love him. his是是形容词性物主代词，放在名词前面。意思是他的，例如：his book.在“He came up with an idea at last,the idea of his''这句话中，his修饰的是‘’idea‘’，''the idea of his''=''his idea'',只是换了一种以of作介词的写法而已。
你只要记住：him修饰动词，his修饰名词。
第12题：这句话的意思是‘’这个篮子里面几乎没有任何东西，它已经空了”，你错在把‘’empty‘’的意思理解为‘’满的‘’，实际上它的意思是‘’空的‘’。''full''才是表示‘’满‘’的意思。
你还有什么疑问吗？
