Lei Feng always thought ------- others first.

是改错题吗?
thought是think的过去式和过去分词,
根据always-- 经常
这里应该用thinks
再问： 是填空题
再答： 填of 雷锋总是第一个想着/关心别人。 1)think of与think about这两个短语表示下列意义时,可以互换. ①考虑 eg:Don't think of/about me any more.不要再考虑我. ②对……有某种看法 eg:What do you think of/ about the film 你认为那部影片怎么样 (2)think of表示下列意义时,一般不和think about换用. ①想要;打算 eg:For a moment I thought of playing truant.我一时起了逃学的念头. ②想出;想到 eg:Who thought of the idea 谁想出的那个主意 ③关心;想看 eg:Lei Feng always thought of how he could do more for the people.雷锋总是想着怎样多为人民做些事情. ④想起;说得 eg:I can't think of his name.我想不起他的名字. (3)think about表示下列意义时一般不和think of换用. ①"回想"过去的事情. eg:We mustn't think about this matter any more.我们不许再想此事. ②"考虑"某事,某计划是否切实可行. eg:I'll think about your suggestion and give you an answer tomorrow think of 是个短语,后面接名词,而think about 后面可以接完整的句子
