Question

高中英语语法题,请大侠帮个忙，谢谢。

① ___is worth mentioning that university lessons can't be the only prepartion for all of the situations __in the working world.
答案是 what that
我不明白为什么第二个空填that
②Scientists believe native Americans arrived by crossing the land bridge that connected Siberia and ____ more than 10,000 years ago
A. this is Alaska B. Alaska is now C. is now Alaska D. what is now Alaska
为什么选D
③_____,he doesn't know how to manage people well.
A. Smart as Jack is B. as Jack is smart
请问是选哪个？

请帮帮我，谢谢。
③为什么选A，D没打错哦

Answer 1

①第二个填that是因为它是定语从句，preparing是先行词，先行词在句子中做主语，所以填which或者that，但是先行词前面有the only或者the very 时就只能填that了
②这里选D。用what代替native Americans arrived by crossing the land bridge that connected Siberia（你试着把what换做native Americans arrived by crossing the land bridge that connected Siberia 然后读下句子看能不能理解）
③选A。这句话是倒装句（结构是：形容词＋though／as＋主语＋be动词，你只要记得这个结构就能够做题了，希望对你有帮助。）

Answer 2

in the working world 修饰 situations
第二题你要是没有打错就不可能选D
选A就算杰克很聪明，他也不知道如何去管理人

Answer 3

1.“all of the situations __in the working world”这一部分是“定语从句”，in the working world 做定语修饰 all of the situation
2.“what is now Alaska more than 10,000 years ago”这个短句做宾语
3.A

Answer 4

1.前面有一个All 啊,所以只能用that
2.What is now Alaska 。。。。。为What 引导的主语从句，指Siberia
3.A
