1 C and后面引导的是并列句,what在主语从句中作主语.
2 D 主谓一致的用法,切记这样的句型.A together with /with / as well as /including B结构中谓语动词用单数还是复数取决于A
3 A alive 和living两个词都表示“活着的”、“有生命的”,living与alive都可作表语
例如：Is his father still living?The old man is still alive.
living可以作前置定语修饰形容词；alive则不可.living主要指在某个时候是活着的,而alive指本来有死的可能,但仍活着的.而且,作主语补足语或宾语补足语时,只能用alive；作比喻义（如“活像……”、“活生生的”等）解时,要用living.lively 生动的,活泼的 live 现场的
4 C 否定性副词在句首,用倒装形式
5 C point是先行词,后面是地点状语从句,钟的滴答声减弱到听不到的程度,用where表程度.
