5．Now it is enjoyed by people all over the world. 现在全世界的人都喜欢这项运动。
is enjoyed是被动语态，by people all over the world 被全世界的人。这一句也可改写成： People all over the world enjoy it now.
6．Its neither too hot nor too cold all the year round. 全年天气既不太冷也不太热。
neither… nor… 既不……也不……，它们可以用来连接相同的两个句子成分或词类。如果连接的是主语，则谓语与第二个主语保持一致。
例：(1) He isnt a student. Im not a student.
Neither he nor I am a student.
(2) He doesnt speak French. He doesnt speak Japanese.
He speaks neither French nor Japanese.
Neither…nor的完全肯定形式是：both…and或not only…but also。
但both…and如连接主语，则谓语动词用复数，not only…but also与第二个主语保持一致。
例：He likes singing. I like singing, too.
Both he and I like singing. ( = Not only he but also I like singing. )
7. Li Lida, a 12-year-old schoolboy first tried to cross the Qiongzhou Channel in June, 20xx.
在20xx年6月，一个12岁的男生李立达第一次试着横渡琼州海峡。
（1）21-year-old在这里可以看作是一个合成词，作形容词用，用来修饰schoolboy。在英语中，数字+量词构成的复合形容词，中间要加连字符号，量词用单数形式。
例如：100-metre race 一百米赛跑。
two-month holiday两个月的假期。
试比较：The boy is five years old.
He s a five-year-old boy.
（2）cross为动词，是越过、穿过的意思。意思相近的词有：through（prep）．穿过，指从……（内部或空间）中穿行，across（prep）．横过，指从物体的表面由这边到另一边。另外，through可作副词用。
cross与across含义基本相同，但cross是动词。over也可表示横过；通过，着重强调越过某物，从高空中越过。
例：（1）Jack was through with the English test.
杰克通过了这次英语测试。
（2）The old lady crossed the street carefully and slowly.
那老妇人慢慢地、小心地走过街去。
（3）The ship passed through the bridge.
轮船过了桥。（从桥下穿过）
（4）The boy climbed over the wall to get his ball.
那男孩爬过墙去取球。
（5）The blind man walked across the street slowly.
那盲人慢慢地走过街道。
