17世纪，原产美洲的高产作物土豆传入中国。与此相关的背景是（）

A.随着丝绸之路的开辟而引进

B.新航路开辟后，由于世界联系加强而传入

C.英法等资本主义国家侵略中国时带入

D.郑和下西洋时从美洲带回

答案

参考答案：B

解析：本题主要考查新航路的开辟。依据所学可知，丝绸之路是汉朝时期开通的，故A项错误；郑和下西洋并未达到美洲，而方向是东南亚和非洲，故D项错误；英法侵略之前土豆已经传入我国，故排除C。新航路开辟之后，世界各大洲之间的联系逐渐密切，土豆也随之传入我国。所以选B。

I passed the test excellently despite my　　of lost study time, but the one thing I needed to learn most wasn’t on that test. I had　　being the best student so that I had failed at just being normal. So what　　to me most? What I have is all about my personal　　and about me being too self-centered. There can only be so many scholars, but there is　　enough sympathy.
