桃花源记

陶渊明

  ①晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之。复前行,欲穷其林。

  ②林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田美池桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。

  ③见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,成来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”

  ④既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。

  ⑤南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

(2007年普通高等学校夏季招生考试英语(北京卷))C

Lying in the sun on a rock, the cougar (美洲狮) saw Jeb and his son, Tom, before they saw it. Jeb put his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar. It worked. The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too.

Jeb let go of his jacket, grasped Tom and held him across his body, making a cross. Now the cougar’s enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and struggled free of Jeb.

“Tom, no!” shouted his father.

But Tom broke and ran and that’s the last thing you do with a cougar. The second Tom broke free, Jeb threw himself on the cougar, just as it jumped from the rock. They hit each other in mid-air and both fell. The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted.

Cougars are not as big as most people think and a determined man stands a chance, even with just his fists. As the cougar’s claws(爪子)got into his left shoulder, Jeb swung his fist at its eyes and hit, hard. The animal howled(吼叫)and put its head back. Jeb followed up with his other fist. Then out of the comer of his eye, Jeb saw Tom. The boy was running back to help his father.

“Knife, Tom,” shouted Jeb.

The boy ran to his father’s bag, while Jeb started shouting as well as hitting, to keep the cougar’s attention away from Tom. Tom got the knife and ran over to Jeb. The cougar was moving its head in and out, trying to find a way through the wall Jeb was making out of his arms. Tom swung with the knife, into the cougar’s back. It howled horribly and ran off into the mountains.

The whole fight had taken about thirty seconds.

63. Why did Jeb pull his jacket open when he saw the cougar?

A. To get ready to fight.              B. To frighten it away.   C. To protect the boy.    D. To cool down.

64. What do we know about cougars?

A. They are afraid of noises.                                     B. They hesitate before they hit.

C. They are bigger than we think.                             D. They like to attack running people.

65. How did Jeb try to hold the cougar’s attention?

A. By keeping shouting and hitting.                          B. By making a wall out of his arms.

C. By throwing himself on the cougar.                      D. By swinging his fists at the cougar’s eyes.

66. Which of the following happened first?

A. The cougar jumped from the rock.                        B. Tom struggled free of his father.

C. Jeb asked Tom to get the knife.                                   D. Jeb held Tom across his body.
