boost和expand作“增加”区别

Question

boost和 expand作“增加”区别

Answer 1

作为动词, boost 有这些意思：
1. (由下或由后) 推,升,提
2. （俚) 吹捧(候选人等),支援,增加,提高,促进
expand 的意思是
扩大,扩张,伸展,张开,延伸,（使）膨胀
虽然 expand 在一些语境下可意译为“增加”, 但直接翻译不是“增加”
例句：
The use of high octane gasoline will generally boost the performance of these cars.
The new trade agreement expands the list of products which may be imported into each country.
