本课简介

当一个物种的死亡率高于出生率时,久而久之这个物种就会灭绝。自生命产生起的数百万年间,已有多个物种灭绝。无法适应环境变化的生物,难以与适应性更好、更强壮的生物相抗衡的生物,其最后的命运都将是消亡。在过去的几十年中,人为地猎杀动物或是改变其生息的自然环境已使得其些物种灭绝。如此事便不胜枚举。亚马逊地区自然环境的改变、植被的毁坏将使多个物种灭绝。盲目无度地猎杀动物使得北美的水牛几近灭绝。

越来越多的人们开始关注野生动植物的保护。方法之一是将濒临灭绝的物种移进动物园和公园,使它们有可能繁衍足够多的后代将来能重返自然。方法之二是建立野生动物保护区,使动物在自然环境中得到照顾。

本课语言点

1. An animal species becomes extinct when it fails to produce enough young in each generation to keep pace with the death——rate.

本句中become是连系动物, extinct是形容词,extinct 通常指动、植物的种灭绝,不再存在。句子中的it代指 (the) animal species.

fail to do sth. 意思是“没能做到…”如:

1)He failed to realize his dream of flying round the world.(他没能实现飞行世界的梦想。)

2)I failed to persuade him to give up smoking.(我没能劝说他把烟戒掉。)

3)Don't fail to live up to what your parents expect of you.(别辜负父母对你的期望。)

4)Don't fail to wake me up.(不要忘记叫醒我。)

Keep pace with 是一个常用词组,意思是“跟上”,如:

1)He was too old to keep pace with the modern ideas of life.(他年纪大了,跟不上现代生活观念。)

2)Earnings have not kept pace with inflation.(收入还没有与通货膨胀的速度保持同步。)

2. We can tell from fossil evidence in rocks that many living species become extinct over the million of years since life began.

本句中的tell不是“告诉”的意思,而是“断定”或“辨别”的意思。如:

1)Can you tell her from her twin sister?(你能分得出她和她的孪生姐妹吗?)

2)Can you tell which is right?(你能断定哪一人是对的吗?)

that在句中引导宾主从句,做tell的宾语。

1)He had had a bad cold over Christmas.(他在圣诞节期间得了重伤风。)

2)They read a lot of books over the vacation.(假期里他们看了不少书。)

3. …… extinction is the fate of any animal that has specialized too far to change when its environment changes, or has to compete with a better-adapted and more powerful animal.

that在句中引导定语从句,修饰animal.

specialize 通常指“专门研究,专门从事”,如:

1)He specializes in medicine. (他专攻医科。)

2)This shop specializes in cooking utensils.(这家商店专门经销饮具。)

在本课文中specialize的意思是“专化,以特殊方式演化。”

Animals and plants are specialized to fit their surroundings. (动植物是按照特殊方式演化以适应各自的环境的。)

too…to…的意思是“太…以致于不能…”如:

1)I was too disappointed to try again.(我太失望,不想再尝试。)

2)He is too young to take care of himself.(他太年幼,照顾不了自己。)

compete with 意思是“与…竞争”,也可用compete against.

1)He didn't want to compete with others for this position.(他不想与别人竞争这个职位。)

2)Sometimes animals have to compete against each other for the chance to survive.

(有时,动物为了生存不能相互竞争。)

better adapted意思是“适应得更好的”。better是副词well 的比较级形式,adapted 是过去分词做形容词用。这类表达形式在英语中十分常见,如:well-known,poorly-dressed,better-prepared等等。

4. A number of examples can be given of the way in which natural environment are being rapidly changed……

a number of 意思是“许多”,如:

1)A number of proposals had been put forward at the meeting. (会上提出了许多建议。)

2)A number of students have passed the exam.(已有许多学生通过了考试。)

of在本句中的意思是关于,相当于about.如:

1)They were not told of this new policy. (关于此项政策,他们没有被告知。)

2)They wanted to know every detail of what had happened.(对于已发生的事,他们想知道每一个细节。)

5. There is every likelihood that many species of animals will be made extinct because of these and similar clearances of natural vegetation.

Likelihood是一个名词,意思是“可能”,相当于 possibility,that在本句中引导同位语从句,对 likelihood作进一步的补充说明。如:There is no doubt that he is a reliable person.(毫无疑问,他是一个可信赖的人。)

Clearance 在本句中的意思是“(植被)砍伐殆尽;清除。”

Clearances of vegetation will lead to the loss of water and soil.(砍伐植被会引起水土流失。)
