现在完成时与一般过去时的区别
现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。
一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。
I saw this film yesterday. （强调看的动作发生过了）
I have seen this film. （强调对现在的影响，电影的内容已经知道了）
Have you read Little Women yet Yes, I have./No, I haven't.
Has Tina read Treasure Island yet Yes, she has. She thinks it's fantastic.
Have you decided which book to write about yet Yes, I have. I've already finished reading it. It was really good.

What do you think of them
What do you think of ... = How do you like ...
表示“你认为……怎么样 ”,用来询问对方对某人或某事的看法和观点。
例如:
—What do you think of the film = How do you like the film
—It’s great.很棒。
易错辨析:think about, think of与think over
think about 考虑,思考 后接名词、代词、动词-ing形式 —What do you think about your Chinese teacher
—I like her very much.
think of 思考,考虑,对……有某种看法 可以与think about 互换 What do you think of the movie =What do you think about the movie
想出,想着,想起 不可用think about 代替 I always think of my childhood.
think over 仔细考虑,认真考虑 其中over是副词,宾语若是名词,则可位于over之前或之后;当宾语是代词时,则必须放在over之前 Think it over before you do it.
It’s very important for you.You must think it over.
