In a small mounitain,have a shack on the slope,you can see a man slash the timber,and a cub squirrel

1.climb the birch是祈使句，还是别的什么？我觉得应该把climb改成climbing
2.spaut... careful错了，动词后面用副词修饰，应该是carefully
3.it wiggle the body make me laugh改成wiggling the body to make me laugh.前面都用过去式了，逗号后面应该时态保持一致，在这里你想表现你看到的场景，介意用伴随时态。
4.Than it jump off the tree,stumble to go my side.同样的时态错误，jump改成jumped，stumble to go my side改成and is stumble to go my side.

按顺序1.in---on
2.have--there is
3.you之前加 where
4.slash---slashing
5.carefull--carefully
6.wiggle--wiggled
7make--making
8.
Than--Then

9jump--jumped
10.stumble--stumbling
受不了，现在还有这种题目？
