文章摘要:专家解题:2012年职称英语考试理工类B级概括大意与完成句子真题及答案解析2,真中国自己可以压制美国时候,你准备让中国做什么?做美国现在做的一切吗?甚至对朋友战友,还不如美国?我看到国力刚强了点,有人就飘了。大家不要互相伤害,勇士前几年的小球战术夺冠确实厉害,但时代是与时俱进的,其它球队二年前都开始针对这种战术研究,好比勇士前年常规赛73胜还丢总冠军一样,去年假如没有杜加盟勇士是赢不了骑士的,现在的火箭就像两年前的勇士一样,其实还比两年前的勇士五小更厉害,所以时代在进步,NBA那么多高手专家在研究,很多人都看在眼里,今年总冠军看好勇士,但前提是勇士必须要有杜兰特。就这场来说,库里得分确实回归正常水准,但是细细分析,在拉开比分的上半场,库里确实发挥很一般,第三节开始后,队友都频频给他喂球,把手感终于喂了出来,这也是库里的一大弱点,他需要在关键时候做出关键的回应,而不是骑士夺冠那年,在第四节最最关键的时刻居然玩背后传球的举动。,就因这样,为此以后真的要做好自己,否则那天我们不再强大了,别人也会学这样对付我们,为此更要努力把事做好。德华来了都扶不起国内所谓的职业球员,伊涅斯塔的性格,白玩。估计还是给的欢乐豆。软实力也是硬实力支撑的。没有以军事实力支撑的硬实力,你那所谓的软实力,话语权就是个笑话。。

   考题类型:概括大意与完成句子


              Learn aboutNoble Gases(惰性气体)

1    Have you ever ridden on aballoon? Many tourist spots offer balloon rides in order for people to see thebeauty of a place from above. A balloon contains a noble gas called helium(氦).Formerly, balloons contained hydrogen but hydrogen is very flammable anddangerous when uncontrolled. Therefore, people shifted to helium, which issafer. Helium is safe because it has the properties of the noble gases.

2    People once believed thatnoble gases couldn’t chemically react at all. For this reason, they were called inertgases(惰性气体). They were also listed under Group 0 in the old periodic tablebecause scientists believed that the gases have zero valence(价) electronsin their outer hell. This was later proven to be untrue when some noble gascompounds were discovered.

3   The gases are elements,which share similar properties. These properties include being monoatomic,colorless, odorless, being able to conduct electricity, and having low chemicalreactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon.These are all found in Group 18, in the rightmost column of the periodic table.If you look at the periodic table, you will notice that these elements are theonly ones, which do not have a charge. Helium has the lowest molecular(分子的) weightwhile Radon is the heaviest.

4   Remember that chemicalreactions occur because atoms have valence electrons, which are electrons intheir outer shell. When the outer shell is “unfilled” or the required number ofelectrons is not yet complete, the atom is more reactive. Noble gases have afull outer shell, meaning that they have complete electrons in their outershell. This complete number varies. For instance, the outer shell of Helium has2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays,there remains to be a few noble gases because of the low chemical reactivity ofthese said gases.

5    Because of theirproperties, noble gases have many important applications. They are widely usedin medicine and industries. For instance, Liquid Helium is used forsuperconducting magnets(磁体). These magnets are very important in physics and medicine. When adoctor suspects that a person’s brain has been damaged, he might request forMagnetic Resonance Imaging (MRI). MRI allows the doctor to “see” the brain,without operating on the patient.

27. Noble gases are not very chemically______.

A. unnecessary  

B. complete  

C. lightest  

D. important    

E. flammable  

F. reactive

 专家解题:

第一步:首先看有没有可以帮助我们解题的语法结构。本题目要选择的是一个能被副词chemically修饰的词,也就是动词或形容词。所有选项都符合条件。所以使用查读法进行解题。确定题干中的信息词为:chemically。

第二步:利用信息词,我们直接回归原文的第二段第一句:People once believed that noble gases couldn’t chemicallyreact at all.

第三步:对比题干和原文。原文中chemically修饰的是动词react,而选项中出现了该单词的形容词形式reactive,所以,本题的答案应该是选项F。该题主要的解题思路就是通过信息词回归以后,找到原文和题干内容的同义改写。

28. Among the elements of noble gases Helium is the____.

A. unnecessary  

B. complete  

C. lightest  

D. important    

E. flammable  

F. reactive

 专家解题:

第一步:首先看有没有可以帮助我们解题的语法结构。本题目要选择的是一个能被定冠词the修饰的名词或最高级。选项中满足这个要求的只有选项C的lightest。The+形容词最高级表达形式。所以,本题的答案是选项C。该题主要的解题思路就是通过冠词the的用法来进行排查和确定答案的。

29. The required number of electrons in noble gases’ outer shell is_____.

A. unnecessary  

B. complete  

C. lightest  

D. important    

E. flammable  

F. reactive

 专家解题:

第一步:首先判断出没有可以帮助我们解题的语法结构。所以使用查读法进行解题。确定题干中的信息词为:The required number of electron,outer shell。

第二步:利用信息词,我们直接回归原文的第四段前半部分:Remember that chemical reactions occur because atoms have “valence” electrons,which are electrons in their outer shell. When the outer shell is “unfilled” or therequired number of electrons is not yet complete, the atom is more reactive.

第三步:对比题干和原文。选项B的complete出现在原文中,所以,本题的答案应该是选项B。

30. MRI may make operating on the patient ______.

A. unnecessary  

B. complete  

C. lightest  

D. important    

E. flammable  

F. reactive

 专家解题:

第一步:首先判断出有没有可以帮助我们解题的语法结构。题干中涉及到单词make的用法,即:使某人/某事怎么样,这里是:使得病人身上的手术____。不能根据这个判断出答案,所以快速确定题干的信息词为:MRI,operating on the patient。

第二步:利用信息词,我们直接回归原文的最后一段后半部分:When a doctor suspects that a person’s brain has beendamaged, he might request for Magnetic Resonance Imaging (MRI). MRI allows thedoctor to “see” the brain, without operating on the patient.

第三步:对比题干和原文。原文中说的是without operating on the patient,也就是不用在病人身上做手术,选项中,A选项的unnecessary是没用的意思,也就是:使得病人身上的手术没用,符合原文的意思,所以,本题的答案应该是选项A。
