Answer 1

我来总结以上观点,并带自己的讲解.
1.each time这个整体相当于连词,引导了时间壮语从句
比如：The moment I saw him I recognized him as the thief.我看见他的那一瞬间就认出他是那个贼.
这里的the moment就是整体做连词,引导时间壮语从句.而带介词的短语,比如at the moment,for the first time是介宾结构,只能做状语,不能起到连词的作用,所以不能引导从句.
2.confirm
表示“证实、确认”的意思.appoint是“任命”的意思,显然不符合句意.
句意为：我致电航空公司以确认我的航班没问题.
3.evidence是不可数名词,所以前面不能加定冠词a/an.表示特指时,前面可加the.
4.on one occasion是“曾经,一度”的意思,楼上说的“偶尔”应该是on occasion(s),不要混淆.
句意为：Jack一度（曾经）喜欢西方饮食,但现在他却钟意中餐了.
5.这题考察省略.when/while/how等特殊疑问词引导的状语从句中,如果是when/while等+主语（和主句主语相同）+be动词的某种形式（is/are/were/has been）的这个结构,那么when/while等引导的这个从句中的“主语+be动词的某种形式”部分可以省略不写.
比如：He was eating while he was watching TV.
=He was eating while watching TV.
所以,须省略be那个部分.
此种省略注意以下几点：1.从句主语和主句主语必须相同.2.从句谓语必须是be的某种形式3.与定语、被动语态区分
