     A popular saying goes, "Sticks and stones may break my bones, but words will never hurt me."

However, that's not really true. Words have the power to build us up or tear us down. It doesn't matter

if the words come from someone's else or ourselves -the positive and negative effects are just as

lasting.

     We all talk to ourselves sometimes. We're usually too embarrassed to admit it, though. In fact, we

really shouldn't be because more and more experts believe talking to ourselves out loud is a healthy

habit.

     This "self-talk" helps us motivate ourselves, remember things, solve problems, and calm ourselves

down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay

positive, we should only speak words of encouragement to ourselves. We should also be quick to give

ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your

room, join me in saying "Good job!"

     Often, words come out of our mouths without us thinking about the effect they will have. But we

should be aware that our words cause certain responses in others. For example, when returning an item

to a store, we might use warm, friendly language during the exchange. And the clerk will probably

respond in a similar manner. Or harsh(刻薄的)and critical language will most likely cause the clerk to be

defensive.

     Words possess power because of their lasting effect. Many of us regret something we once said.

And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it

loving? Is it needed? If what we want to say doesn't pass this test, then it's better left unsaid.

     Words possess power: both positive and negative. Those around us receive encouragement when

we speak positively. We can offer hope, build self-esteem(自尊)and motivate others to do their best.

Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

1. The main idea of the first paragraph is that ________.

A. not sticks and stones but words will hurt us

B. inspiring words give us confidence

A. almost everybody has the habit of talking to themselves

B. we can benefit from talking to ourselves

C. talking to ourselves always gives us courage

D. it does no harm to have "self-talk" when we are alone

2. The underlined part in the third paragraph means that we should also timely _______ .

A. praise ourselves

B. remind ourselves

C. make ourselves relaxed

D. give ourselves amusement

3. The author would probably hold the view that ______.

A. encouraging words are sure to lead to kind offers

B. negative words may encourage us to make more progress

C. people tend to remember friendly words

D. it is better to think twice before talking to others

阅读下文,回答下列问题。

深海的发现:从“大洋中脊”到“深部生物圈”

人们看惯了绵亘的山岭和曲折的海岸,不大会去问“为什么”的问题。90年前,A.WEGENER发现大西洋两侧的非洲和南美岸线可以拼合、又有共同化石,从而提出“大陆漂移”的假说,但当时回答他的只是嘲笑和冷漠。半个世纪之后,深海测量技术发现深海洋底也有高山峻岭,全世界有8万公里长的山脊蜿蜒在各个大洋,而大西洋的中脊恰好与非洲和南美洲的海岸线平行时,人们这才恍然大悟,原来大陆和大洋的岩石圈是分成若干“板块”的整体。

同样,沐浴在阳光下的人们,看惯了飞禽走兽、树木花草,绝不会对“万物生长靠太阳”产生怀疑,又是深海海底“黑暗生物圈”的发现,开辟了新的视野。20世纪70年代末,“址VIN”号深潜器在东太平洋发现了近百度的高温,原来海底有“黑烟”状的含硫化物热液喷出,冷却后形成“黑烟囱”耸立海底。更为有趣的是在热液区的生物群。现在,这类热液生物群在各大洋发现的地点已经数以百计,离我们最近的就在冲绳海槽。

黑暗食物链的基础,是在还原条件下进行化合作用制造有机质的原核生物,据推测与生命起源时的生物群相近。不只是海底,近年来发现在数千米深海海底下面数百米的深处,还有微生物在地,层的极端条件下生存,这种“深部生物圈”虽然都由微小的原核生物组成,却有极大的数量,有人估计其生物量相当全球地表生物总量的1/10。

“深部生物圈”的发现,大大拓宽了“生物圈”的分布范围。原来从极地冰盖到火山热泉,从深海海底到地层深处,生物的分布几乎无所不在,人类迄今研究和熟悉的,只不过是生物圈中的一小部分。不但海底,海水层里也是一样:运用新技术,发现了普通显微镜下看不见的微微型浮游生物。

深海大洋的发现,纠正了我们对生物界的偏见:我们用肉眼、甚至用光学显微镜见到的,只是地球生态系统的上层,只占生物圈的一小部分;地球生态系统的真正基础,在于连细胞核都没有的原核生物。生物的一级分类,应当是古菌、细菌与真核生物三大类,而我们熟悉的动、植物只是真核生物中的一部分。

生物圈概念的扩展,也改变了地球科学与生命科学的关系。传统地质学里生物的“主角”是大化石,而实际改造地球的首先是原核生物,它们几乎没有形态化石可留,只靠生态过程影响着化学元素周期表里几乎所有的元素,在三四十亿年的地质历史上默默无声地“耕耘”,直到今天才有可能得到重新评价。

总之,深海大洋的研究,不仅是地球科学,也是生命科学的突破口。

根据原文提供的信息,以下推断正确的一项是()。

A.深海测量中对“大洋中脊”的发现,为后来“黑暗生物圈”的发现开辟了新视野。

B.现代地质学研究要重视的是几乎没有形态化石的原核生物而不再是大化石。

C.数十亿年来原核生物在改造地球方面所起的重要作用,已开始得到人们的重视。

D.对深海大洋的研究,将是今后开展地球科学和生命科学研究的主要途径。
