【題目】閱讀下面材料，在空白處填入適當(dāng)?shù)膬?nèi)容(1個單詞)或括號內(nèi)單詞的正確形式。

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】

試題分析：本文屬于應(yīng)用文，介紹了人腦中很多區(qū)域并沒有發(fā)揮出作用，如果我們的大腦都被看開發(fā)出來，那么人類就會更加聰明。

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

【2】were 考查虛擬語氣。本句是一個虛擬語氣，與現(xiàn)在事實(shí)相反，所以從句中使用一般過去時，be動詞使用were。

【3】more intelligent 考查倍數(shù)表達(dá)。句式：A is +倍數(shù)+比較級+than.....意為“A是B的...倍”，句意：如果這是真的，那么我們就會比現(xiàn)在聰明10倍。

【4】stimulated 考查時態(tài)。本句敘述的是19世紀(jì)科學(xué)家進(jìn)行的科學(xué)研究，本句要使用一般過去時stimulated。

【5】its 考查代詞。本句中its指代本句主語the animal。句意：當(dāng)科學(xué)家刺激大腦中某一個特殊區(qū)域的時候，那個動物就會移動它的腿或尾巴。

【6】like 考查介詞。介詞like 像....一樣；該詞通常表示列舉事例。句意：現(xiàn)在我們知道在人的身上，很多不應(yīng)區(qū)實(shí)際上是一夜一些復(fù)雜的活動有關(guān)，像語言、學(xué)習(xí)和想象。

【7】as/when 考查連詞。本句中as/when引導(dǎo)時間狀語從句。句意：實(shí)際上，甚至當(dāng)我們睡覺的時候，大腦的很多區(qū)域都是活動的。

【8】Interestingly 考查副詞。英語中的副詞通常做狀語修飾形容詞、副詞或動詞。本句中使用副詞interestingly修飾后面整個句子。

【9】given 考查副詞用法。本句中名詞task與動詞give構(gòu)成被動關(guān)系，所以使用過去分詞given做前置定語修飾名詞task。

【10】of 考查固定搭配。形容詞短語be capable of...能夠做某事；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.

In our life, we often regret what we did and which we couldn’t do. Actually, it doesn’t benefit us at all. As for most of us, we missed many chance to earn more money, to get a high position and to realize our dreams. We often regret that we don’t seize those opportunities, thus feel upset. Although we do know regretting the Past is no benefit, but we still can’t help doing it

To avoid the problem below, we need to pay more attention to what you are doing now, making us busier and having no time to recall the past. Moreover, we’d better set reasonably goals one by one. Only by doing so can we struggle for our future better.
