求教：有句英語用法不理解英語書中有句話：He catches thieves and helps keep the city safe.請問下後面的help和keep兩個動詞為什麼可以連著寫而當中不加任何詞？而且我也查不到任何類似的help的特殊語法用法，所以請教大家，謝謝.希望答案能儘量詳細點.

我記得應該是help（to）do sth to在這裡可以省略的

不明白的要去問老師.用英文怎麼說

You should ask the teacher for help when you meet with problems

超不明白imagine的用法，望幫解答這題謝謝
Some people imagine flying_____more dangerous than travelling by train. Which is wrong.
A.to be B.\ D.being
答案是D注解說AB是複合賓語，
但我不理解D項不能看做是imagine sth /sb doing的結構嗎？flying就是sth，being就是doing
我就是問D怎麼是錯的？

答案應該是A吧imagine sth to be=imagine sth as
Some people imagine flying to be more dangerous than travelling bytrain.Whichis wrong.
to be more dangerous than travelling by train.用來說明flying（也就是賓補）說以說是複合賓語.
這是新概念3册內容
eg.wesometimes imagine a desert island to be a sort of paradise where the sun always shines.
我們有時想像荒島是陽光終日普照的天堂.
to be a sort of paradise where the sun always shines就是用來說明賓語a desert island的情况，也就是賓語補語
