【2】该“喷嚏”还可能产生的明显影响不包括( )

A．短波通讯中断 B．产生极光 C．指南针失灵 D．地球公转速度的变化

【答案】

【1】A

【2】D

【解析】

试题分析：

【1】材料中提到了五彩斑斓的极光、电网会突然变得闪烁不定，而这场灾难仅仅源于太阳打了一个强烈的“喷嚏”，造成以上现象的原因是太阳活动对地球的影响。

【2】太阳活动对地球的影响：扰动电离层，干扰无线电短波通讯；扰动地球磁场，产生“磁暴”现象；使两极地区产生“极光”现象；许多自然灾害的发生也与太阳活动有关。

Science classes are difficult for many students. Fortunately, there are ways to get good grades.

Write it down.

Taking note what is being taught helps a lot more than you would imagine. 1 . You’ll have something ready to refer to if you need a quick refresher(进修). You’ll also be able to catch things your professor might say that won’t be in your textbooks.

2 .

Your professor will do or say things that aren’t in the reading materials. Usually, these provide the professor’s personal understanding on the matter. These enrich your learning and help you apply the theories to everyday life.

Practice.

Science is a matter of practice. 2 . How? It may sound like your mother’s nagging(唠叨) from your elementary school days, but do your homework! Professors give homework for many reasons, and giving you the opportunity to practice is one of them.

Read.

Of course, the foundation of whatever you take up in your science class is the textbook. No matter what, the lesson will always take you back to that thick paper. 4 .

Socialize.

Learning is a lot easier when people are helping each other out. Form a study group, or even just study in the same room as a bunch of your classmates. 5 .

A. Pay attention

B. Focus on your method

C. It’s all a matter of smart schooling

D. The trick is to manage your reading time

E. You’re free to write things in a language making the lesson understandable

F. The best way todrive the facts into your brain is to repeatedly work on them

G. If ever you hit a difficult problem, someone will be around to clarify things for you
