久石榴--悲剧…… 零星狗

Q 50, V 27…… 650

哎…… 郁闷……坐在我旁边的那同学总是清嗓子，戴着耳塞也不管用，V的时候心烦意乱…………………………

AA是裤里的，一个Neoelectronic公司的CEO给HR Director写信，把公司近两年利润下滑归罪于人力资源部招人不利
AI：一个最有经验的员工往往是领导职位的最佳人选

数学没什么感觉是不是狗里的，不过感觉不难，50。

V就彻底悲剧了。有一篇阅读是说鸟类飞翔起源的两种假设。一种假设是说先爬到树上滑翔，另一种是跳起来捕食或躲避敌人。作者觉得两种都不靠谱。还有一个博物馆保存油画的。这两个都似乎见过。

后天托福。托完了再决定要不要重考吧。还要再煎熬一个月………………

再补充一个约读：挺短的一篇，说什么可再生能源的。也是似曾相识。开始定义了一下可再生能源，说如果有可再生能源，就不用烧石油什么的了。 第二段说在没有发现更靠谱的可再生能源前，也可以尽量高效地烧这些石油什么的。有个公司就帮他的用户尽量高效地使用这些非可再生能源。…… 现在思维有点混乱。大概就是这个意思吧

Two opposing scenarios,        两种解释鸟飞的假设：树栖和疾走。
the “arboreal” hypothesis and
the “cursorial” hypothesis, have
Line traditionally been put forward con-
(5)  cerning the origins of bird flight.
The “arboreal” hypothesis holds      树栖论说鸟祖先爬上树滑行下来，随
that bird ancestors began to fly       着羽毛越来越大，最终飞了起来。
by climbing frees and gliding
down from branches with the
(10) help of incipient feathers: the
height of trees provides a good
starting place for launching flight,
especially through gliding. As
feathers became larger over time,
(15) flapping flight evolved and birds
finally became fully air-borne.
This hypothesis makes intuitive       树栖论的问题：始祖鸟和M恐龙没有
Sense, but certain aspects are         明显的栖树适应性，如合适的脚。
Troubling. Archaeopteryx (the
(20) earliest known bird) and its
maniraptoran dinosaur cousins
have no obviously arboreal
adaptations, such as feet fully
adapted for perching. Perhaps        没分析显示始祖鸟曾用前肢爬树和飞，
(25) some of them could climb trees,
but no convincing analysis has
demonstrated how Archaeopteryx
would have both climbed and
flown with its forelimbs, and there
(30) were no plants taller than a few       始祖鸟化石发现的地方也没有发现高
meters in the environments where      树。
Archaeopteryx fossils have been
found. Even if the animals could       即使它会爬树也不表明会滑翔。
climb trees, this ability is not
(35) synonymous with gliding ability.
(Many small animals, and even
some goats and kangaroos,
are capable of climbing trees
but are not gliders.) Besides,
(40) Archaeopteryx shows no obvi-
ous features of gliders, such as        它没明显的滑翔特征。
a broad membrane connecting
forelimbs and hind limbs.
  The “cursorial”(running)
(45) hypothesis holds that small           疾走论认为鸟为了躲避猎食者，奔跑
dinosaurs ran along the ground        并张开双臂平行
and stretched out their arms for
balance as they leaped into the
air after insect prey or, perhaps,
(50) to avoid predators. Even rudi-         前肢的原始特征能帮助身体稍微升高
mentary feathers on forelimbs
could have expanded the arm’s
surface area to enhance lift
slightly. Larger feathers could         然后鸟慢慢就飞起来了。
(55) have increased lift incrementally,
until sustained flight was gradu-
ally achieved. Of course, a leap
into the air does not provide the
acceleration produced by drop-
(60) ping out of a tree; an animal
would have to run quite fast
to take off. Still, some small
terrestrial animals can achieve
high speeds. The cursorial
(65) hypothesis is strengthened by
the fact that the immediate the-         兽脚亚目恐龙祖先拥有各种疾走的
ropod dinosaur ancestors of            特点。
birds were terrestrial, and they
had the traits needed for high
(70) lift off speeds: they were small,
agile, lightly built, long-legged,         另外，
and good runners. And because         它们用两足走，双臂有空用来拍打。
they were bipedal, their arms
were free to evolve flapping flight,
(75) which cannot be said for other
reptiles of their time.

---------------------------------------------------------
Q 3:
The primary purpose of the passage is to

A.    present counterevidence to two hypotheses concerning the origins of  bird flight
B.    propose and alternative to two hypotheses concerning the origins of bird flight
correct certain misconceptions about hypotheses concerning the  origins of bird flight
C.    (missing)
D.    refute a challenge to a hypothesis concerning the origins of bird flight
E.    evaluate competing hypotheses concerning the origins of bird flight

---------------------------------------------------
Q 4:
The passage presents which of the following facts as evidence that tends to undermine the arboreal hypothesis?

A.    Feathers tend to become larger over time
B.    Flapping flight is thought to have evolved gradually over time
C.    Many small animals are capable of climbing trees.
D.    lants in Archaeopteryx’s known habitats were relatively small
E.    Leaping into the air does not provide as much acceleration as gliding out of a tree

------------------------------------------------
Q 5:
Which of the following is included in the discussion of the cursorial hypothesis but not in the discussion of the arboreal hypothesis?

A.    A discussion of some of the features of Archaeopteryx
B.    A description of the environment known to have been inhabited by bird ancestors
C.    A possible reason why bird ancestors might have been engaging in activities that eventually evolved into flight
D.    A description of the obvious features of animals with gliding ability
E.    An estimate of the amount of time it took for bird ancestors to evolve the kind of flapping flight that allowed them to become completely airborne

-------------------------------------------------
Q 6:
The passage suggests which of the following regarding the climbing ability of Archaeopteryx?

A.    Its ability to climb trees was likely hindered by the presence of incipient feathers on its forelimbs.
B.    It was probably better at climbing trees than were its maniraptoran dinosaur cousins.
C.    It had certain physical adaptations that suggest it was skilled at climbing trees.
D.    Scientists have recently discovered fossil evidence suggesting it could not climb trees.
E.    Scientists are uncertain whether it was capable of climbing trees
