A vs B
谓语+插入语+宾语从句,宾语从句前面的that放在哪里主要取决于插入语修饰的对象,
如果插入语修饰谓语动词,则插入语紧跟谓语动词,that+宾语从句。如we decided, in view of his special circumstances, that we would admit him for a probationary period.
如果插入语修饰宾语,则插入语紧跟宾语从句,谓语动词+that,插入语,宾语从句。如he told her parents that, due to her illness, she would be able to go to school tomorrow.
D.besides做介词+名词,可以做定语也可以做状语,如The cat on the couch loves dogs. on the couch做定语。
E.besides是副词+动词,-ing可以做定语也可以做状语,如The cat sleeping on the rug belongs to Sue.
从词性上无法区分。看and和or的区别。
状语比较的时候,可以省略than后面整个主句,不管时态是否一致。
Eg:
Scientists have gathered evidence suggesting that complex life-forms emerged much earlier than previously thought.
than previously thought (when they emerged)
时间状语的比较,能否省略取决于than前面是否有相应的时间状语。有则than后面主句可以省略;没有则than后面需要补出主谓,以避免比较对象上的歧义。
Eg:
Right: Prices are only 1.3 percent higher this year than last year.
Wrong: Prices are only 1.3 percent higher this year than last year's.
