人类最好的朋友 狗是人类最好的朋友。它可以为我们做许多事情。它可以保 护我们的家。它可以引导盲人。它对主人忠实而且从不要求加 薪。 狗还对英文有许多的贡献。举例来说，如果没有狗的话，做 丈夫的如何告诉他太太她煮的菜吃起来像狗食?气象播报员又如 何能用猫和狗来表示雨下得很大呢?因此，下次有狗对你的自行车 抬腿撒尿时，可别踢它。要弯下腰对它说：“慢慢来。”

Lesson 143
Man's Best Friend
The dog is man's best friend. He can do
many things for us. He can protect our
homes. He can guide the blind. He is loyal to
his master and never asks for a pay raise.
The dog has also made many contribu-
tions to English. For example, if there were
no dogs, how could a husband tell his wife
her cooking tastes like dog food? How could
the weatherman say, "It's raining cats and
dogs?" So the next time a dog lifts a leg to
your bicycle, don't kick him. Bend down and
say, "Take your time."
