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。
That is about 10 times less than the tech giant Meta spent building its latest A.I. technology.这里less than是不是不能看做整体,而是less当作表语,10times修饰less,后面than… 当作比较状语从句?
