DoDo鸟是一种不会飞的鸟，仅产于毛里求斯肥。拥有肥胖的身子和巨大的嘴。
16世纪后期，欧洲殖民者来到了毛里求斯。不会飞又跑不快的DoDo鸟很快成为欧洲人来到岛上后主要的食物来源。人们开始大量的滥捕滥杀可怜的DoDo鸟，有时每天可以捕杀到几千只到上万只。

1. They lived on the earth tens of millions of years ago, long before humans came into being and their future seemed secure at that time.
[点拨1] 本句是一个由and连接的并列句，其中，long before 引导时间状语从句，进一步解释说明tens of millions of years ago，意为“在……之前很久”。注意：before long 意为“不久以后”。
Language points
[点拨2] on the earth. 在地球上。在earth,
sun, moon等表达世界上独一无二的名词
前, 要加the。
[点拨3] come into being的意思是“开始存
在;发生”。
我们不知道这世界是什么时候存在的。　　　　　　　　　　　　　　
We don’t know when the world came into
being.
I knew Tom long before I knew you.
我在认识你之前很久就认识汤姆了。
We hope to finish our experiment before long.
我们希望不久就把实验做完。
It ___ long before we___ the result of
the experiment.
A. will not be; will know B. is; will know
C. will not be; know D. is; know
2. When scientists inspected the bones, they were surprised to find that these dinosaurs could not only run like the others but also climb trees.
[点拨] 本句中的to find that ...是不定式作原因状语。不定式用来表原因时，常修饰表示情感、心理状态、性格等的形容词，如：
happy， glad，lucky， fortunate， surprised， angry，anxious， cruel， clever， frightened，shocked， sorry， eager， proud，disappointed， foolish， impatient，unwise， naughty等。如：
We were surprised to see him.
我们真想不到会见到他。
We are proud to be young people of new China.
作为新中国的青年，我们感到很骄傲。
You were foolish to act like that.
你那样做很愚蠢。
3. Some scientists think it came after an unexpected incident when a huge rock from space hit the earth and put too much dust into the air.
[点拨] 本句中when引导定语从句，其先行词为incident。关系副词when 的先行词一般是表时间的名词，如: He came last night when I was out. 但有时并不直接是表时间的名词，如：
In 1921 Einstein won the Nobel Prize, and was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.
1921年爱因斯坦获得了诺贝尔奖，他在德国很受尊敬。纳粹上台后由于他是犹太人而被赶出了德国。
