Explanation of difficult sentences

1. It seemed that the world was at an end. 似乎世界末日来临。

seem连系动词，似乎，好像

1）seem + (to be ) + adj./n.

2）seem + to do

3）seem + like + n.

4）It seems/seemed (to sb.) + that-clause如：Our English teacher seems to be a kind

man. He seems to know everything = It seems that he knows everything. It seems like

years since we last met. It seems that I have seen her before. = I seem to have seen

her before.

2. Everywhere they looked nearly everything was destroyed.人们无论朝哪里看，

几乎一切都被毁了。

everywhere 用作连词，等于wherever, no matter where，引起让步状语从句。如：

Everywhere I go, I find the same thing.无论我去哪儿，我都看到一样的东西。You

see it everywhere you look.无论你往哪儿看，你都会看到它。

3. …90% of its homes were gone.90%的家都不存在了。

是过去分词作表语，意为“不在”“走了”“丢了”“用完了”，或指人“死了”。分数、百分数作主语，谓语动词要根据分数、百分数代表的量是可数名词还是不可数名词而定。如：His job was gone.他的工作丢了。My watch was gone.我的表不见了。He’ll be gone for quite a little while.他要离开很长一段时间。50% of the students in our class are girls.我们班50%的学生是女生。Two-thirds of the earth surface is covered with water.地球表面的三分之二是水。

4. The army organized teams to dig out those who were trapped and to bury the

dead.救援人员组成小分队，将被困的人挖出来，将死者掩埋。

those who相当于意为“凡……的人”，表示的是两者以上的不定数量，who引导的定语从句用复数，不能用that代替。（注意：anybody who, he who中谓语动词用单数。）

the dead意为“死难者”。形容词或分词前加表示同一类人或物，谓语动词常用复数形式。如：Those who want to see the film write your names on the paper.想看电影的人把你们的名字写在这张纸上。Anybody who breaks the law will be punished.任何人犯法都要受到惩罚。He who laughs last laughs best.谁笑在最后，谁笑的最好。The rich are not always happy.有钱人并不总是幸福的。

5. To the north of the city, most of the 10,000 miners were rescued from the coal mines. 在城市的北部，一万矿工中的大多数从矿井中被救出。

in the north, to the north与on the north

in表示“在其中”，在境界内；to表示在境外，不接壤；on表示接壤。如：China lies in the east of Asia.中国位于亚洲东部。Japan lies to the east of China.日本位于中国的东面。（指在中国境外）China faces the Pacific on the east.中国东临太平洋。（指东部境界与太平洋相接）
