Question

Her baby is only ( ).He can't speak .A、three-month-old B、three months old.选哪个

Her baby is only ( ).He can't speak .A、three-month-old B、three months old.选哪个我觉得是A，可答案是B，为什么？

（ ）The girls don't go to school _____ the heavy rain.
A、because B、because of.

Answer 1

我觉得是a three-month-old baby 所以选b下一个选 because of 因为后面是名词，不是句子 because和because of

because是连词，其后接原因状语从句或回答以why开头的问句；

而because of是复合介词，其后接名词、代词或动名词，或者what引导的名词性从句。

如

(1)___he is ill,he is absent today.

(2)He is not at school___his illness.

(3)He can”t come___the heavy rain.

(4)We like physics___we can learn a lot
of ideas.

答案：1.Because 2-3.because of 4.because

Answer 2

1.选B.
A是复合形容词后面需要跟名词，例如：I am a sixteen-year-old boy.
B.位于be后做表语

2.选B
A.because后跟的是从句.B.because of跟的是短语或名词.而the heavy rain是一个短语

Answer 3

1、选A的话，把old前面的连字符去掉。
2、B。because of +名词。

Answer 4

B
