一日一词:ONSET

自现象级英语

ONSET

1. 英英释义:the beginning of something, especially something bad 

例句:Evidence shows that speaking a second language can help delay the onset of dementia. 

2. 为什么选这个词? 

“onset”是个名词,意思是“开始”,常常可以用来完美替换常见的“beginning”,是外刊中经常出现的表达。onset 表示“开始”时,后面常接有负向含义的名词,比如疾病、经济萧条、战争等。 

比如战争开始后,犯罪率激增,就可以说成: 

Since the onset of the war, the crime rate has skyrocketed.

有证据表明,会说一门外语有助于推迟老年性痴呆(dementia)。我们就可以用 onset 造句: 

Evidence shows that speaking a second language can help delay the onset of dementia.

最近的《经济学人》中也出现了 onset: 

The study adds substantial weight to the evidence linking cannabis to the onset of psychosis.(“the onset of psychosis”指“精神疾病的开端”,这句话是说研究表明吸食大麻很有可能导致患上精神疾病)

3. 怎样学会使用这个词?

1)翻译下面的句子: 

经济危机爆发后,投资面貌发生了巨大变化。 (重点:爆发后 since the onset of, 投资面貌investment landscape,巨大变化 be changed tremendously )

The investment landscape has been changed tremendously since the onset of the financial crisis.

My version: In the wake of the financial crisis, the investment landscape has significantly transformed.

造句:

例1:The landscape of public health is likely to deteriorate at the onset of vector-born diseases such as malaria. 疟疾等虫媒病对公共健康的危害

例2:The onset of higher fuel costs is a clear indicator of growing traffic and pollution problem.改编自每周一段

例3:Evidence shows that blue economy and green economy can help delay the onset of global warming. 改编例句

个人拓展:

搭配:the onset of sth;

delay / mark / after/ since /at the onset

背诵:

onset, beginning

Evidence shows that speaking a second language can help delay the onset of dementia.
