学位英语，历年必考“义同形异词”汇总，学位英语考试中有很多义同形异的单词，为方便考生复习，小编汇总了学位英语考试主要考查的义同形异词，供大家参考~
1.over / above
"over"和"above"这两个介词的意思是在…….上面。
我们可以说(1)The sky is above our heads,也可以说(2)The sky is over our heads.
我们也可以说(3)He spread his handkerchief over his face.但不能说(4)He spread his handkerchief above his face.
同样的，可以说(5)John has travelled all over the world以及 (6)The King reigns over a great empire，但是(5)和(6)里的 "over"却不可以"above"取代。
2.bring / take
"Bring"和"take"的意思相同，但用法并不一样。
"Bring"指东西向说话的人的方向去，如：Bring me the book, please.
"Take"指东西向说话的人离去，如：
Take the dictionary away from me .
由此可见，"bring"和"take"都表示东西要移动，只是方向不同："bring"向说话者而来;"take"向说话者而去。
3.certain / sure
"certain"和"sure"都含“确定”之意，只是在句中的用法有些不同。
下列第九到十一的句子都对，但第十二的句子就不行了：
(9) We are certain to come to the party. / Tom is sure to come today.
(10) I am not certain whether I will be able to do it. / Are you sure that you will do it?
(11) It is certain that Jason will leave me.
(12) It is sure that Jason will leave me.
4. rob / Steal
虽然这两个字都是及物动词，但用法不同，不可互相取代。
"Steal"的宾语通常是被偷的东西，如“钱，手表”之类。"Rob" 的宾语必须是“人”或“地方”。如：
(13) A thief entered her house and stole her valuables.
(14) A stranger robbed a passer-by.
(15) Who robbed the bank last night?

5.chase / follow
这两个动词，一个是“追逐”，另一个是“跟随”，都是人家在前，他在后，但用起来不一样;"chase"不但是动词，也是名词，如：
(16)The cat chased the mouse and caught it soon after.
(17)The pupils followed the teacher to the classroom.
(18)There was a thrilling car chase in the film.
(19) Social unrest follows widespread unemployment.
(20) I could not follow what he was saying.
