数学对于主体知识,那些同一道解答题经常得4分的,在高考中也很难拿满分;但如果你拿了8分、10分,就说明完全有能力去拿满分,就一定要从细节入手,比如说表达形式:集合、定义域、值域、单调区间;比如范围中的端点值;直线与圆锥曲线位置关系的直线斜率存在与否的计算,严谨是数学的学科特点。

高中英语比起初中的英语来说就难的多了,这时候我们需要在英语上下更多的功夫才能够把英语学习好,而对于高中英语语法-at which point的用法这些重要的基础的知识正式我们学习英语的砖头。
at which point的用法
at which point用于引导定语从句,其意为“就在这时”“就在那时”等,在许多情况下相当于 and at that (this) moment。如:
He lost his temper, at which point I decided to go home. 他发脾气了,这时我就决定回家了。
The speaker paused to examine his notes, at which point a loud crash was heard. 讲演者停下来查阅他的笔记,就在这时,听到了砰的一声巨响。
The film started to get very violent, at which point I left. 那部电影看着看着出现了极残暴的场面,我立刻就走了。
【注意】千万不能在 at which point 前加并列连词。如:
讲演者停下来查阅他的笔记,就在这时,听到了砰的一声巨响。
误:The speaker paused to examine his notes, and at which point a loud crash was heard.
正:The speaker paused to examine his notes, at which point a loud crash was heard.
正:The speaker paused to examine his notes, and at that moment a loud crash was heard.
