Recently the New York Animal Medical Center made a study of 132 cats over a period of five
months.
make?a?study?of?sth 對(duì)什么作出研究
over a period of five months
All these cats had one experience in common: they had fallen off high buildings, yet only
eight of them died from shock or injuries.
in common = the same
fall?off 墜落，掉落
die?of?+ illness, disease, hunger, thirst
die?from?+ shock, injures, wound
Of course, New York is the ideal place for such an interesting study, because there is no
shortage of tall buildings.
Shortage（n.不足, 缺乏）= lack（n.缺乏, 短缺），兩個(gè)詞都和of搭配
-- Shortage of money led to the failure of the experiments.
資金缺乏導(dǎo)致實(shí)驗(yàn)的失敗。

only suffered from a broken tooth.

-- The more you eat, the fatter you will be.
be?likely?to?do 有可能如何（強(qiáng)調(diào)可能性）
-- In cold winter, we are likely to catch a cold.
In a long drop, they reach speeds of 60 miles an hour and more.
and?more 甚至更多（= more than 60 miles an hour）
At high speeds, falling cats have time to relax. They stretch out their legs like
flying squirrels.
at high speeds
stretch??out 充分伸展
This increases their air-resistance and reduces the shock of impact when they hit the ground.
Special difficulties 難點(diǎn)

3> such an （exhibition n.展覽會(huì)）
