生词： inexorable 不可阻挡的；无法改变的

错题一

B段应该选哪个作为标题？
答案： ix. Fundamental differences in ageing of objects and organisms物体和生物体衰老的根本差异

解析： B段前半段:Our ‘dead’ products are ‘ static’, closed systems. It is always the basic material which constitutes the object and which, in the natural course of things, is worn down and becomes ‘ older’… Although the same law holds for a living organism, the result of this law is not inexorable in the same way. 要想弄清楚这一段的意思，至少要阅读前半段，才能明白作者是在对object变旧的过程和生物体衰老的过程做对比。通过is not inexorable in the same way猜测出是对应答案中的fundamental differences。正确答案为ix。

错题二

D段应该选哪个作为标题？
答案： vii. A stable life span despite improvements 尽管有所改进，但寿命稳定

解析： D段第二、第四句:but within one species the parameter is relatively constant. Although more and more people attain an advanced age as a result of developments in medical care and better nutrition, the characteristic upper limit for most remains 80 years.
本段指出，每个生物体都有极具特色的寿命；不同物种之间的寿命有很大差别，但同一物种中，这个参数相对恒定，这就是选项vi中所提到的a stable life span；接下来的although则可以对应Heading中的despite,，improvement 对应句中的developments in medical care and better nutrition。这样就和Heading的意思完全吻合了。正确答案是vi。

错题三

E段应该选哪个作为标题？
答案： i. The biological clock生物钟
E段首句:…it is logically necessary to propose the existence of an internal clock, which in some way measures and controls the ageing process and which finally I determines death as the last step in a fixed programme. 本段首句中提到：如果寿命是一个由基因决定的生物特征，那么我们就有必要提出这样一个观点，那就是生物体内存在一个内部时钟。这是文章第一次提到生物钟这样一个概念。正确答案是i。

错题四

F段应该选哪个作为标题？
答案： vii. A stable life span despite improvements

定位词：energy consumption
F段第一、四句及末句:Animals which behave ‘frugally’ with energy…
Animals which save energy by hibernation or lethargy …
That means that they live life energetically’—more intensively, but not for as long. 通读全段，感到几乎在每一句中都存在的energy一词向你呼喊:选我吧。这样的段落无法从某一句话中弄明白作者到底在讲什么，但是也没有必要过于精细地通读全段。只需要浮光掠影扫过全段,捡拾几个高频词，就能够猜测出段落大意。
个别考生可能会选iii，因为他们只看到在该段中提到男、女新陈代谢比率的不同，但却没有注意到这一段除了提到男、女，还提到了乌龟、鳄鱼等，出项并没有涵盖全段要表达的意思。正确答案是viii。

错题5、6

Objects age in accordance with principles of ____ and of .
文中对应B段第三句:Ageing in this case must occur according to the laws of physical chemistry and of thermodynamics.
题目:物品变旧的过程依据_____和_ 法则。
并列的两处空格中需填名词。首先到文中寻找objects一词， 可以在B段顺利找到，然后请注意寻找并列关系连接词and，很快可以发现正确答案。答案为physical chemistry (and ) thermodynamics。

错题七

Through mutations, organisms can _____ better to the environment immortality would pose a serious problem for the theory of evolution.
答案： adapt
错误答案： adaptation
文中对应C段第五句:Because of changes in the genetic material (mutations) these have new characteristics and in the course of their individual lives they are tested for optimal or better adaptation to the environmental conditions. 首先通过mutations一词将此题在文章中定位，虽然寻找过程不容易，但是一定要相信自己能找到。定位之后寻找空后关键字better to,根据空格前的情态动词can推测空格处只能填一个动词，而且是原型，还要能和to搭配。这么一来，这句话里只有一个对应词比较合适:adaptation，将其变形为动词即可。答案为adapt。

错题八

The wear and tear theory applies to both artificial objects and biological systems.
正确答案：N

参考译文：自然磨损理论既适用于人造物品也适用于生物系统。
定位词：the wear and tear theory
解题关键词：both… and…
文中对应B段:Our ‘dead’ products are ‘ static’, closed systems. It is always the basic material which constitutes the object and which, in the natural course of things, is worm down and becomes ‘older’. Ageing in this case must occur according to the laws of physical chemistry and of thermodynamics, Although the same law holds for a living organism, the result of this law is not inexorable in the same way.
我们所谓“死掉”的产品是指一些“静态的”封闭的系统。构成物体的基本材料总是会在自然过程中逐漸磨损，变得“老化”。根据物理化学和热力学的规律，在这种情况下老化是必然的。虽然相同的规律也适用于生物体，但这一规律并不会以同样的方式产生不可抗拒的结果。
A段提出问题，B段解答问题。通过上面三句话得知：对于生物体而言，死亡并非不可阻挡的，因此自然磨损理论对于生物体来讲，当然就不太适用了。

第二篇： A Chronicle of Timekeeping 钟表编年史

Our conception of time depends on the way we measure it

And, for those living near the equator in particular, …

第三篇： COLLECTING AS A HOBBY收集作为兴趣

正确率9/13

生词： individualism = the quality of being different or original 个性；独特气质
engrossing引人入胜的;使人着迷的
mildly略微地;温和的

错题一

Collecting sometimes involves a life-long ____ for a special item.

答案： hunt|desire

定位词：Life-long，a special item

第四段第一、二句：Another motive for collecting is the desire to find something special, or a particular example of the collected item, such as a rare early recording by a particular singer. Some may spend their whole lives in a hunt for this.

题目是关于a special item的收藏问题，文中第四段开头说收藏行为的一种动力是he desire to find something special, 而第二句说Some may spend their whole lives in a hunt for this。这与题目中的special item及life-long含义一致，因此答案为desire或hunt。

错题二

______ tends to be mostly a male hobby.

答案： Trainspotting

第六段第一句：In the past - and nowadays, too, though to a lesser extent - a popular form of collecting particularly among boys and men, was trainspotting.

本题提到a male hobby,文中第六段第一句提到a popular form of collecting, particularly among boys and men是trainspotting,这与题目表述一致，内此本题答案trainspotting.

错题三

Someone who collects unusual objects may want others to think he or she is also unusual.
答案： True

参考译文: 一些收藏不寻常物品的人或许希望别人认为他们与众不同。

定位词: collects unusual objects

对应第九段第一句: One reason, conscious or not, for what someone chooses to collect is to show collector’s individualism.

本句说无论我们是否意识到，一些人选择收藏行为是为了show the collector’s individualism,之后举例说明了这一点，这与题目中的表述是致的，因此本题答案为TRUE。

错题四

Collecting gives a feeling that other hobbies are unlikely to inspire.
答案： True

参考译文: 收藏行为会带来种其他爱好无法激发的感受。

定位词: Collecting gives a feeling

文中对应点 第十段第一、二句: Of course, all hobbies give pleasure, but the common factor in collecting is usually passion: pleasure is putting it far too mildly. More than most other hobbies, collecting can be totally engrossing, and can give a strong sense of personal fulfillment.

本题说收藏行为带给人的感受问题，在文中第十段中，作者写道all hobbies give pleasure, but the common factor in collecting is usually passion: pleasure is putting it far too mildly,可见本身收藏行为带来的感受会强于一般爱好。在后续的论述中，作者也使用了be totally engrossing, a strong sense of personal fulfillment这类表达，都充分说明了其他爱好无法与之相比。因此本题答案为TRUE。
