问题 单项选择题

作为整体,中国在世界上举足轻重;但作为个人,不少中国人还觉得自己一无所有。国家之强和个人之弱使一些人心理失衡,觉得自己活得还是像在半殖民地时代受人家欺负的受害者。正因如此,我们更需要对自己生存的状态有理性的认识,克服狭隘的“受害者情结”。否则,崛起的中同将难以担当与自己的国际地位相称的责任。
这段话谈论的核心意思是()。

A.中国急需提高国民的个人地位

B.中国人需要调整自己的心理状态

C.中国人为什么有“受害者情结”

D.崛起的中国要承担相应的国际地位

参考答案:B

解析:

[命题提示]

本题主要考查考生理解文意和概括中心的能力

[解题要点]

分析文段有几层意思,并加以归纳概括,善于抓住中心意思

[答案与解析]

这段话首先通过列举事实进行对比,表明中国有些人心理失衡,此为第一层,即第一、二句;第二层应为后面两句,即第三、四句。“中心句”应是带关联词“正因如此”的句子,故中心意思为“我们更需要对自己生存的状态有理性的认识……”,归纳起来,就是:中国人需要调整自己的心理状态。A、C、D项都不是文段的核心意思。故选B。

It sounds like a science fiction, but researchers say it’s a scientific fact: Microscopic organisms dubbed "killer algae" are paralyzing fish with unknown toxins and then eating away at their flesh. They might be making people sick, too.
The name given to this single-cell organism, or dinoflagellate, is Pfiesteria piscimorte- literally, "fish killer. " It was discovered at North Carolina State University in 1988, but at the same time, few scientists believed in its existence, much less in its highly unusual predatory nature. But ongoing research has led to international acknowledgment of the phenomenon and, recently, research funding.
Seemingly prompted by an unknown substance secreted by fish, the aggressive creature swims into action. It sends neurotoxins into the water and air, paralyzing a fish’s nervous system, and causing it to gasp for air at the surface. Eventually the fish suffocates. The killer dinoflagellate then attaches itself to the fish and begins sucking away at its flesh. This macabre scenario may help solve several sea mysteries, such as why fishermen report seeing "fish walks" (fish trying to leave the water) and pools of dead fish with holes eaten through them.
Whether humans are affected by the dinoflagellate’s toxin remains to be seen. Researchers think it’s unlikely eating fresh fish are in danger, but anyone with frequent exposure to the creature could be in peril. Several researchers working with the algae have reported bouts of memory loss and disorientation.
To understand the killer algae further, scientists must fully characterize their toxin and determine what stimulates them to attack. They also need to know if the algae are hurting fish populations, and whether pollutants make them more likely to attack.

Researchers think that it is ______.

A. safe to eat fresh fish

B. dangerous to get close to the algae
C. safe to be near the algae

D. dangerous to expose the algae
