1.c return=come/give back ,不能再使用back.
2.d.over改为above above sea level 海平面以上
3.c.宾语从句的从句要求使用陈述句语序.
4.a.I/we think..的否定式要求否定前移,即否定从句的否定词移到主句.

in the days

C。删掉
D。above
C。he will
A。don't think he is

楼上 2.山没有特指，为什么要a变the ，实为考介词问题
4.你的改法改变句意，实际错误要考否定前移

第一个是 c ，有return就不需要back
第二个是 d ，应用 above
第三个是 c，特殊疑问句应该是疑问词加陈述句，应该是 he will
第四个是，don't think he is

1.c back去掉
2.b a变成the
3.c 变成 he will
4.c very去掉
