改错题两道

it 要放在up之前，look up 是个词组，it作为代词只能放在介词up之前，如果是名词的话就可以放在up后面或look up之间。
第二句consider后面接动词ing做考虑的意思，因为consider是个及物动词，他的用法为consider sb/sth (for/as sth)或者consider doing sth

3.If you don't know the meaning of the word, you (may) look up it in your dictionary.
up it--->it up / look sth up查找某物
下面是翻译软件的例句
If you don't know a word, you can look it up in a dictionary.
如果你有不识的字,可以查字典。

4.I am considering (to visit) Paris next month
to visit--->visiting
consider +doing

第一个是 look it up
用法是look up sth. 或 look+代词+up

第二个是considered，一般不用ing形式，改成thinking也可以

1. you may look it up in your dictionary.动词和副词构成的短语接名词宾语时，宾语可以在两次中间也可以放短语后。例如 look up the word / look the word up 均可。但是，如果宾语是代词时就只能放两次中间。
2.i am considering visiting Paris next month
考虑做某事应为：consider doing sth

1.look it up
2.I am considering to visitING Paris next month.

1.look up it改为look it up，代词要放中间
2.to visit改为visi
