Answer 1

你好，很高兴为你解答。

保证正确率~！

• 正确答案是：
  

16 修饰动词move的进行时态，要用副词steadily

17 因为系安全带是在他们被扔出去之前，是在过去的过去，故用 had fastened 

18 but 表转折，虽然脸色很苍白，但是依然很镇定。

19 any 表示“任何”，这里的 if 不是条件句里面的 if ，它的意思是“是否”。

20 a 表示泛指，泛指一个男人。

21 instructions 和 send 存在被动关系，且强调当时收音机正在播放的，所以用过去进行时的被动语态。

22  which 引导的非限制定语从句，指的是plane，并在定语从句充当主语，即是 is dangerously close to the ground 的主语。

23 be familiar with 对...很熟悉

24正常的语序是： the critical moment when he had to land came. ，只因主语过长， when 后面的句子才后置， when he had to land 是做the critical moment 的后置定语里的时间状语成分。

25  follow 和 the man 存在主动关系，这里是现在分词做伴随状语，表示和guided这个动作几乎同时发生的一个动作 。

不懂请追问，(*^__^*) 嘻嘻~~

望采纳，祝开心~！！！

追问

问题1：怎么知道它是强调当时收音机正在播放的
问题2：如果……instructions that ___21___(send) by……去掉that应该怎么填 谢谢

追答

1 从语境来说的，听的时候肯定在放啊，都放过了，还认真地听毛线啊~？懂了吗？
2 去掉 that，填 being sent 就可以了，这样就是现在分词做后置定语了。

追问

为什么去掉that能直接用being sent

追答

去掉 that ，这里的 being sent 就是现在分词啊。
就像： There is a girl crying over her spilt milk
= There is a girl that is crying over her spilt milk
一个女孩正在为她洒掉的牛奶哭泣。
现在分词含有一种正在进行的意味。
所以，这里可以填 being sent。

Answer 3

although the passengers ___17___(fasten) their seat belts,they were suddenly thrown forward.
17. had fastened; although引导让步状语从句。过去完成时表示系安全带的这个动作发生在主句被动动作were suddenly thrown forward之前，
译：乘客尽管已系好安全带，却突然地向前摔倒。
Moving the pilot aside,the man took his seat and listened carefully to the urgent instructions that ___21___(send) by radio from the airport below.
21. were being sent，
译：将飞行员弄到一边，这人坐上了他的位置并认真地听着通过无线电从下面机场发过来的紧急指令。
析：that were being sent by radio from the airport below 是限制性定语从句，修饰先行词the urgent instructions. 关系代词that在定语从句中作主语，指代的是复数名词instructions, 指令和发送是被动关系，所以用被动语态。这事情发生在过去，听的时候指令正通过无线电发送过来，所以是过去进行时的被动语态。

Answer 4

16. 修饰动词move的进行时态，要用副词unsteadily
17. had fastened; 过去完成时表示动作fasten在were suddenly thrown forward之前发生.
18. but, 但是
19. ask if any,是否有人.这是固定短语
20. a, 其中之一
21. instructions (as radio waves) were being sent by radio from the airport, sent...by ... from...,sent 是被动, 且强调当时收音机正在播放的，所以用过去进行时的被动语态。
22. which was dangerously close to the ground at the moment,描述plane
23. be familiar with 对...很熟悉. 这是固定短语.
24.moment...when时间状语,这是固定短语
25.following描述如何guided the plane toward the airfield

问题1：怎么知道它是强调当时收音机正在播放的
问题2：如果……instructions that ___21___(send) by……去掉that应该怎么填 谢谢

追答

1.正在播放，才可以listened. urgent instructions一直播放. urgent ,不要停，需要保持联系
2.去掉that...urgent instructions being sent by radio from airport below. being sent描述urgent instructions

Answer 5

16.unsteadily adv.不稳定地
17.although后面跟的是虚拟语气，因为后面是过去式，故而这里用过去完成时。
18.表示转折，说的是“她看起来脸色很苍白，但是非常冷静。
19.if后面表示的是疑问语气，故而用any
20.表示量词
21.这里用的是过去进行时，但是，因为紧急信息是被发出来的，所以，用了be动词，但是，又是正在进行的动作，所以be being done sth，但是，文章主时态是过去时，这里主语又是单数，所以用was
22.定语从句先行词
23.be(become) familiar with sth
24.这里时表示同时发生的动作，用when
25.(who was) following the instructions 状语从句
