帮忙分析一下这几个英语单选，谢谢啦

Not until the taxi disappeared in the distance _______her handbag was gone。
这个为什么填did Tina find呢
When Christine landed her job some years ago,she had to face a climate____music classes were not the focus of learning.
为什么填where呢

Answer 1

1 Not until the taxi disappeared in the distance _______her handbag was gone。
填did Tina find是因为 not until ...位于句首 ，主句要部分倒装 ，也就是用疑问句语序;
正常 语序是 Tina didn't find her handbag was gone until the taxi disappeared 。
记住 这个倒装句 的句型即可;
另外 再 记住 它的强调句it was not until the taxi disappeared in the distance that Tina found her handbag was gone。2 When Christine landed her job some years ago,she had to face a climate____music classes were not the focus of learning.
这是定语从句;
先行词climate的意思 是 风气、氛围;
填where= in which
;也就是 在这种氛围里 ， 作从句中的 状语

Answer 2

倒装的一个 很明显的要求，否定副词 放句首需要倒装，否定副词包括一下几个很常用的：little/ no/ never
第一句是not 放在来了句首所以要引起后面的倒装
第二句是考察定语从句。
当先行词为 climate/situation/circumstances/point/等，并且 定语从句中 主谓宾 完整的时候。引导定语从句的 是 where。
被动句式 是 主谓宾完整的另外一种表现形式，
music classes were not the focus of learning，显然是完整的，不缺少任何成分。
所以 填where。
希望对你有帮助。

Answer 3

1、Not until ..... did sb do ..... Not until 提前，部分倒装。
2、定语从句，还原之后是：Music classes were not of the focus of learning in the climate. 原句缺少介词 in 成分，所以用where。

Answer 4

第一题。 因为not在句子中被提前了 根据语法规则 要进行倒装 did是助动词 因此要放 到主语前面。 第二题，考察的是定语从句 when引导的是状语从句 可以搁置一边 那真正的主句是she开始的 空开始是一个定语从句 定语从句中主谓宾都有 说明是个完整的句子 所以缺少状语 根据语意 先行词是个抽象的概念 所以用where
