Question

请帮忙说下promote和strengthen做“提高”讲的区别

Answer 1

简单地说：promote是值得程度上的提高，（引申出促进的含义），比如be promoted to the next grade提升一级/promote business促进业务,开发业务/promote the sale of
products推销产品
英语习惯上，
1.表示“提升,晋级”意义时,常用于被动语态。例如:
Within a year he was promoted from teller to
assistant cashier.他一年内就由出纳员升至(银行)负责财务助理的高级职员。

2.作“促进,提倡”等义解时:promote原来只用于好的东西,但现在也可以用于坏的东西,这时与lead to同义。例如:
Certain
foods promote tooth decay.有些食物会腐蚀牙齿。
The bad news promoted/led to
disorder.这个坏消息引起了混乱。
3.表示“推销,宣传”(商品)。例如:
The company are promoting their
new products on television.这家公司正通过电视宣传其新产品。

strengthen一般指程度上的加强，make or become strong or stronger的意思。（引申为加强、巩固gain strength ）
to strengthen his argument
加强他的论点的分量——to weaken his argument 削弱他的论点的分量;The team was strengthened by his
presence.他的出场加强了这个队的实力。——The team was crippled by his absence.他的缺场削弱了这个队的实。The wind ～ed during the night.
夜间风势变强。
