2. I applied for the job, and they sent me an invitation to try out for a part in the chorus.

我申请了这份工作，他们给我发了邀请，让我在合唱团里试演一个角色。

【巧解句构】这是一个由and连接的并列结构，句中短语apply for意思是"申请"，try out表示"试用，测试"。

【拓展延伸】1）apply 的常见短语

apply sth. to sth.把......运用到（贴到、涂到）......

apply to sb. /sth.与某人/某物有关

2)短语try out意思是"试用，测试"。如：

他迫不及待地想试开他的新车。

与try有关的词语：

3. The empeor finds the deaths of so many men disturbing, and although he would like to, he cannot break his promise.

国王为这么多男人为此而死亡感到烦恼，但他又不能违背自己的诺言，尽管他想这样做。

【巧解句构】整个句子是由and 连接的并列结构。句中find...disturbing表示"觉得......很恼人（烦恼）"，although he would like to 采用了省略形式，break one's promise 表示"违背诺言，失信"。

【要点剖析】动词不定式符号to后面的动词或动词短语在句中重复出现时，往往可以省略，使语言表达更为精炼。详见"语法解读"。

误区警示 如果不定式中含有be, have, have been,通常保留be, have和have been。如：

1）-Are you a sailor?你是一名水手吗？

-No, but I used to be.不，但我过去是。

2）-He hasn't finished yet.他还没完成呢。

-Well, he ought to have.哦，他早就应该完成。
