(难度B/A级/2008年理工类教材新增文章)

备战英语二的同学常常会听到师兄师姐说:“考英二,简单,随便复习复习就可以了。”但英语二真的那么简单吗?真的可以在*后关头缩减复习时间吗?今天就跟大家分析下英语二,帮助咱们考生抓住复习的方向。

The Tiniest Electric Motor in the World

通过对往年英语二的考试大纲分析,可知英语二**应放在词汇,语法以及各个题型解题方法的训练。接下来我们详细看下各个项目复习的侧**及应对策略。

  1. Scientists recently made public the tiniest electric motor ever
    built. You could stuff hundreds of them into the period at the end of
    this sentence. One day a similar engine might power a tiny mechanical
    doctor that would travel through your body to remove your disease.

  2. The motor works by shuffling(来回运动) atoms(原子) between two
    molten metal droplets(小滴) in a carbon nanotube(纳米管). One
    droplet is even smaller than the other. When a small electric current is
    applied to the droplets, atoms slowly get out of the larger droplet and
    join the smaller one. The small droplet grows – but never gets as big as
    the other droplet – and eventually bumps into the large droplet. As they
    touch, the large droplet rapidly sops up (吸入)the atoms it had
    previously lost. This quick shift in energy produces a power
    stroke(动力行程).

  3. The technique exploits the fact that surface tension — the tendency
    of atoms or molecules to resist separating — becomes more important at
    small scales. Surface tension is the same thing that allows some insects
    to walk on water.

  4. Although the amount of energy produced is small — 20
    microwatts(百万分之一瓦) — it is quite impressive(给人印象深刻的)
    in relation to(与…相比) the tiny scale of the motor. The whole setup
    is less than 200 nanometers on a side, or hundreds of times smaller than
    the width of a human hair. If it could be scaled up to the size of an
    automobile engine, it would be 100 million times more powerful than a
    Toyota Camry’s 225 horsepower V6 engine.

  5. In 1988, Professor Richard Muller and colleagues made the first
    operating(工作的, 运行的) micromotor(微型发动机), which was 100
    microns(微米) across, or about the thickness of a human hair. In 2003,
    Zettl’s group created the first nanoscale motor. In 2006, they built a
    nanoconveyor(纳米传送带), which moves tiny particles along like cars
    in a factory.

  6. Nanotechnology(纳米技术) engineers try to mimic nature, building
    things atom-by-atom. Among other things, nanomotors could be used in
    optical circuits to redirect light, a process called optical switching.
    Futurists envision(预想) a day when nanomachines(纳米机器), powered
    by nanomotors(纳米发动机), travel inside your body to find disease and
    repair damaged cells.

2018考研英语二怎么复习?英语二应对策略及复习**

练习:

英语二主要考查大家对
“常用”词汇和词组的掌握,所谓“常用”,指的就是基础词和核心词。在之前的阶段,同学们已经通过单词书背了单词,到现阶段,除了在书中巩固单词外,建议每天做真题时将不认识的核心词和基础词整理出来并加以理解记忆,记忆的**:核心词的基本含义以及基础词的生僻含义。这样就可以在有限的复习时间里**地掌握词汇。

  1. Paragraph 2

  2. Paragraph 4

  3. Paragraph 5

  4. Paragraph 6

很多考生一提到语法就头晕,英语那么多语法点根本抓不住,怎么办?其实咱们考研英语有自己的语法体系,尤其是咱们英语二,因为考试大纲直接指出了8大语法考点:

A An introduction of a Toyota’s 225 horsepower V6 engine.

名词、代词的数和格的构成及其用法;

B A description of the nanomotor in terms of power and size.

动词时态、语态的构成及其用法;

C [u]Surface tension[/u](表面张力).

形容词与副词的比较级和***的构成及其用法;

D Previous inventions of nanoscale(纳米级的) products.

常用连接词的词义及其用法;

E The working principle of the nanomotor.

虚拟语气的构成及其用法;

F Possible fields of application in the future.

各类从句及强调句型的结构及其用法;

指定的四个段落都没有明显的段落主题句(2007年理工类A/B级概括大意题中四个指定段落都没有明显段落主题句),考生可以通过通读指定段落的大意来归纳出段落主题,
或借助一些有效的答题技巧确认段落主题。以确认段落第4段的段落主题为例分析答题技巧:

倒装句、插入语的结构及其用法。

A An introduction of a Toyota’s 225 horsepower V6 engine.

同学们只要认真将语法书上这8大考点掌握到位,考卷中遇到的长难句自然能够快速理解其含义。现实告诉我们如果语法混乱,考题中的语句就读不懂,这样直接导致无法解题以及得分,所以我们还是得依托考纲指出的语法**反查自己是否能够在语法上做到滴水不漏。那么怎样评估自己语法是否掌握扎实呢?如果大家在考题中遇到的任何长难句能够在1-2分钟内抓住其主干,分清从句类型,理解句子的大意,那就说明语法掌握到位,否则,必须按照考纲规定将语法从头过一遍,理解语法基本知识点。
