请曹教老师,
A slow Internet link speed is really bothering.
1. 为何要使用冠词a?
Research shows that jogging can bring many health benefits.
2.Research 前是否需要定冠词the?为什么?
谢谢曹老师。
1 speed可以是不可数名词,也可以是可数名词。
例如《牛津》例子:a speed of 50 mph/80 kph
这种用法时,通常speed有限制性定语修饰,表示一种什么样的速度。
有时不可数名词被形容词修饰后,也可以用不定冠词表示一种的意思。例如,fever(发烧)为不可数名词,但一个人发高烧,可以说 He has a high fever.
2 research可以是不可数名词。但英国英语也用复数形式。以下为《牛津》的释义:
[uncountable] (also researches[plural] especially in British English) a careful study of a subject, especially in order to discover new facts or information about it.
Recent research on deaf children has produced some interesting findings about their speech.
你的句子中,research是不可数名词,所以用零冠词表示泛指。
