Scientists do not know why this animal became extinct. But some theories
postulate
that changes in geography, climate and sea levels were held responsible.
选项
A、promise
B、predict
C、pretend
D、presume
答案
D
解析
(1)句子结构。
本题是由两个独立的句子构成。第一个句子的结构为主动宾(SVO),主语为Scientists,谓语动词为do not know,宾语为why引导的宾语从句。第二个句子的结构同样为主动宾(SVO),主语为some theories,谓语动词为postulate,that引导的从句为宾语从句。
(2)选项词义。
A.promise vt.允诺,许诺;给人以……的指望或希望
B.predict vt.预言,预测;预示,预告
C.pretend vt.假装,伪装;假称;装扮
D.presume vt.认为;假设;推测
句子大意为“科学家们尚不清楚这种动物灭绝的原因,但一些理论认为其灭绝是因地理、气候和海平面变化所致”。postulate意思是“认为”,与选项中的presume词义最为接近,因此选项D正确。
【知识拓展】词汇拓展:postulate与presume。
①postulate v.to suggest or accept that sth.is true so that it can be used as the basis for a theory, etc.
e.g.They postulated a 500-year lifespan for a plastic container.
他们认为塑料容器的寿命为500年。
②presume v. to accept that sth.is true until it is shown not to be true,especially in court
e.g.In English law, a person is presumed innocent until proved guilty.
英国法律规定,在证明一个人有罪之前,会先假定他是无辜的。
