【解析】

本文介绍了世界土地划分和人口。2000年世界人口达到60亿。世界上三分之一是陆地。世界上有七大洲四大洋，但是并不是所有的土地都适合人们。

1.根据“In the year 2000, the world's population was about six billion. That's 6,000,000,000!”可知2000年，世界人口大约60亿。故答案为There were about six billion people. / About six billion people. / About 6,000,000,000 people.

2.根据“There are seven continents：Africa, Asia, Oceania, Europe, North America, South America and Antarctica.”可知七大洲包括：亚洲、欧洲、北美洲、南美洲、南极洲、非洲、大洋洲。题目问“你住在哪个洲”，参加考试的都是住在中国的，因此是亚洲。故答案为I live in Asia. / Asia.

3.by作时间介词意为“到……之前”；此句是宾语从句，scientists“科学家”作主语；谓语动词predict意为“预测”；从句主语the world意为“世界”；will是一般将来时标志；have表示“有”；billion意为“十亿”；people意为“人们”。故答案为科学家们预测，到2025年世界上将会有78亿人。

4.“The world has four main oceans. ”中four为个数，对four提问用How many引导的特殊疑问句，此处has为实义动词，改为疑问句，助动词does提前。故答案为How many main oceans does the world have?

5.此句是主系表结构，Not all land意为“不是所有的大陆”；be good for表示“对……有好处；适合于”，land作主语，be动词用is；people意为“人们”。故答案为Not all land is good for people.
