陷阱
⚠️boost(正面推动)不用于负面语境
Extreme weather events have boosted the number of natural disasters recorded globally over the past two decades.
极端天气事件使过去二十年全球记录的自然灾害数量有所增加。(负面增长用 increase/fuel,× boost 含正面义)
boost 通常含正面推动义(向上提振);负面语境中增加数量用 increase / fuel / drive up;× boosted the number of disasters(灾害增加不是「提振」)→ ✓ increased / fuelled the number of disasters
Extreme weather events have increased the number of natural disasters recorded globally over the past two decades.
极端天气事件使过去二十年全球记录的自然灾害数量有所增加
⚠️give a boost to(名词用法)固定结构
The announcement of the new international airport gave a significant boost to the regional economy and property market.
× gave a significant boost for(介词 for 可以替换 to)
give a boost to(为…提供推动力)是固定结构,介词 to;× give a boost for 不是固定表达;也说 a boost for tourism(介词 for 在名词「a boost for...」结构中也可:a boost for the economy = 对经济的促进);但 give a boost to 是固定动词短语
新国际机场的宣布为地区经济和房地产市场提供了显著的推动力。(give a boost to = 固定表达)
