(教材P51) It is still not known if he succeeded in reaching the top of Qomolangma before it took his life.

目前还不清楚他是否在丢掉性命之前成功登上珠峰峰顶。

句式分析：该句中it是形式主语，后面的if引导的从句是真正的主语。而且此处的it不可用其他词如this，that等来代替。在英语中，只有it可作形式主语。

It is not known if he is fit for the job.

还不清楚他是否适合这份工作。

2、either...or...要么……要么……

(教材P51) With the majority of attempts to climb Qomolangma resulting either in total success or failure，is there also a scientific reason behind this risktaking?

大多数登珠峰的尝试要么完全成功，要么彻底失败，在这种冒险行为背后是否也有科学依据呢？

句式分析：本句中either...or...是连接词，意为“或者……或者……；不是……就是……”。在这里连接两个宾语。

I'm going to major either maths or biology in university，as both are my favorite subjects.

在大学里我打算要么学数学，要么学生物，因为这两个都是我最喜欢的科目。

[知识拓展]

either...or...主要用于表示选择，其意为“要么……要么……”“或者……或者……”，用于连接两个性质相同的词或短语；连接两个成分作主语时，谓语动词通常与其靠近的主语保持一致。除可连接两个词或短语外，有时也可连接两个句子。其否定式可以是not either...or...，也可以是neither...nor...。

Either you or I am wrong.It is impossible that we are both right.

五、难句分析

1、(教材P50) For these people，climbing Qomolangma is an experience like no other，making some feel weak and others，powerful.

[分析] 此句是一个主系表结构的简单句。Climbing Qomolangma是动名词短语作句子的主语。like no other是介词短语意思是“与众不同”。making some feel weak and others，powerful是动名词短语作定语修饰表语an experience，结构为：make sb.do sth.，and 后面为省略结构，原句应该为making others feel powerful。

[译文] 对于这些人来说，登珠峰是一种与众不同的体验，能让一些人感到虚弱，让另一些人感到强大。

2、(教材P51) Psychologist Frank Farley has spent years studying people who jump out of planes and drive fast cars，as well as those who climb Qomolangma.

[分析] 此句是一个主从复合句。主句是主谓宾结构的句子。其中spend time doing sth.后面的宾语people后面有两个who引导的定语从句；as well as连接两个定语从句。

[译文] 心理学家弗兰克法利用多年的时间研究那些高空跳伞以及开快车的人，以及那些登珠峰的人。
