参考答案:3、could you tell me__________?
A.who are they B.who they are C.how old are they D.how are they
选 B, 这里考察的是宾语从句的语序，应该用陈述句语系，就是主谓宾语序，主语 主语 they 谓语 are 表语 who
4._________they were poor, they sent their children to school.
A.if B.because C.now that D.although
选 C， 从意思判断， 尽管他们很穷，但还是送他们的孩子去上学。
5.could you tell me__________?
A.how much the boy weighs B.how many the boy weighs
C.how much does the boy weigh D.how many does the boy weigh
选 B， 这里有两个考点，首先是how many和how much的区别，how many是修饰可数名词的，how much是修饰不可数的，这里的重量是可数的，所以用how many， 第二个考点是宾语从句的语序问题，所有名词性从句都是用陈述句语序。 以下的题目考点都一样。 主要分清楚句子结构，主谓宾，定状补就可以拉。
6.the boby can be________in the hospital.
A.taking good care of B.taken good care of
C.take good care of D.takes good care of
选 B， 这里考察被动语态， 跟在be动词后面，要么是现在分词，要么是过去分词， 由于孩子是被照顾，所以要过去分词表被动。
9.no one knows___________.
A.when are they going to leave B.when they are going to leave
选 B。 宾语从句的陈述句语序，同上解释。
问题补充：9.no one knows___________.
A.when are they going to leave B.when they are going to leave
C.when do they leave D.when did they leave
选B， 其余三个选项都是疑问句语序，可以排除拉。
