题目内容

【题目】阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

Have you ever heard that we humans use only ten percent of our brains? This myth holds 【1】 certain appeal because if it 【2】 (be) true, then we could instantly become ten times 【3】 (intelligent) just by firing up that sleepy majority of the brain!

The idea that we use only a small fraction of the brain dates back to animal experiments in the 19th century. When scientists 【4】 (stimulate) a specific part of the brain, the animal moved 【5】 leg or tail. And some scientists assumed that large parts of the brain were simply useless.

Then, in the early 20th century, scientists observed that stimulating certain regions of the brain had no physical effects, which are called the “silent cortex”. Today we know that in humans, much of the “silent cortex” is actually devoted to complex activities 【6】 language, learning, and imagining.

Actually, even 【7】 we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity? 【8】 (interest) enough, the opposite is probably true. The less brain activity you need to perform a 【9】 (give) task, the more the brain as a whole is capable 【10】 doing.

【答案】

【1】a

【2】were

【3】more intelligent

【4】stimulated

【5】its

【6】like

【7】as/when

【8】Interestingly

【9】given

【10】of

【解析】

试题分析：本文属于应用文，介绍了人脑中很多区域并没有发挥出作用，如果我们的大脑都被看开发出来，那么人类就会更加聪明。

【1】a 考查固定搭配。固定短语a certain一些，表示泛指。这件奇怪的事情引起了一些人的注意。

【2】were 考查虚拟语气。本句是一个虚拟语气，与现在事实相反，所以从句中使用一般过去时，be动词使用were。

【3】more intelligent 考查倍数表达。句式：A is +倍数+比较级+than.....意为“A是B的...倍”，句意：如果这是真的，那么我们就会比现在聪明10倍。

【4】stimulated 考查时态。本句叙述的是19世纪科学家进行的科学研究，本句要使用一般过去时stimulated。

【5】its 考查代词。本句中its指代本句主语the animal。句意：当科学家刺激大脑中某一个特殊区域的时候，那个动物就会移动它的腿或尾巴。

【6】like 考查介词。介词like 像....一样；该词通常表示列举事例。句意：现在我们知道在人的身上，很多不应区实际上是一夜一些复杂的活动有关，像语言、学习和想象。

【7】as/when 考查连词。本句中as/when引导时间状语从句。句意：实际上，甚至当我们睡觉的时候，大脑的很多区域都是活动的。

【8】Interestingly 考查副词。英语中的副词通常做状语修饰形容词、副词或动词。本句中使用副词interestingly修饰后面整个句子。

【9】given 考查副词用法。本句中名词task与动词give构成被动关系，所以使用过去分词given做前置定语修饰名词task。

【10】of 考查固定搭配。形容词短语be capable of...能够做某事；有做某事的能力；

As it is often the case, when people are attending meetings, having meals or waiting for buses, you can always find them addicting to their phones, completely ignoring others.

This is really a common phenomena in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat. Therefore, too much exposure to phones are bad for people in terms of health. Moreover, people involved in phones fail to communicate well with these around them.

As far as I am concerned, people should wisely make use of their phones to help their work and study. Meanwhile, care much about their family and friends rather than mobile phones.
