consider的基本用法及与regard,think of/about和look(up)on as的区别
consider一词在历年高考中是一个常考的要点，其用法应分为两部分来讲。

第一、作“考虑、思考”时的搭配如下：
1．consider+n./pron.，例如：
Have you considered the suggestion?
That’s what we have to consider now.
2．consider+v-ing，但不能接不定式的一般式，例如：
We considered going to see the doctor the next day.
Have you considered moving to shanghai recently?
You must consider to tell him something about it.(错误) 3．consider+疑问词+不定式，例如：
He is considering how to improve his English.
We must consider what to do next.
4．consider+从句，例如：
We didn’t consider whether he should go or not.
Have you considered when we should go there?
第二、作“认为、把……当作/看作”等意思时的搭配如下：1．consider+sb/sth+(to be/as)+n./adj.，例如：
I consider him to(be/as)my best friend.
Everyone considers him(to be)clever.
He considered it much improved.
2．consider+sb./sth.+不定式短语（作宾语补足语），不能接不定式的一般式，例如：
We consider them to be working very hard.
We consider them to have finished the work.
We consider him to be the clever in our class.
We must consider him to go there at once.(错误)
3．consider+it+adj./n.+不定式短语，其中it为形式宾语，不定式短语为真正的宾语，例如：
Jiao Yulu considered it his duty to serve the people heart and soul. They consider it necessary to set the slaves free.
4．Consider+sb/sth介词短语作宾语补足语，例如：
She always considered herself in the right
We considered his suggestion of great importance.
5．consider+宾语从句，例如：
We considered that the film was worth seeing for another time.

另外，（1）consider的名词形式为consideration，常用于下列的结构：1．He showed much consideration for his wife.
2．He didn’t take part in the meeting in consideration of his job. 3．You can’t answer my question without consideration. 4．Your plan is under consideration.
（2）considerable意思为“可观的、相当的（接不可数名词）、值得思考的、重要的”等，例如：
1．The increase was considerable.
2．Your plan is considerable.
第三、consider与regard的区别：
consider指经过深思熟虑或由亲身
经历而“认为”，搭配见前面。

regard指用眼睛看这种判断通常基于表面的观察，后面接复合结构，一般由名词来充当，不接形容词或动词不定式，一般as连用，例如：
1．We regarded him as one of the best teachers in our school. 2．I regard picking pocket as a crime.（我认为扒窃是一种罪行）
第四、think about和think of也都有表示“考虑、认为、想一想”的意思，常接表示事物的名词或动名词，例如：
1．She is thinking about/of changing his job.
2．What do you think about/of our plan?
3．Have you thought about/of my suggestion?
第五、look on/upon as意思为“把……看作、视为”，后面一般接名词，例如：
1．Do you look on him as an authority（权威）on the subject. 2．He usually looks upon my idea as a joke.（他常把我的意见视
为儿戏）。
