嗨，童鞋们好，我是学姐，高中生想要学好英语，首先要明确的一个观点就是：英语是不能速成的，学好英语没有捷径可走。有些同学不愿吃苦，只顾投机取巧，钻研方法和技巧，不愿在学习内容上花时间和精力，这部分同学首先要解决的是态度问题。外语学习的过程是练功夫的过程，需要长期坚持不懈的努力。
The most central root in the word “activate” is “act”. “Act” is a common root that means “to do” or “to perform”. “Active” is an adjective formed from “act” and the suffix “-ive”， which means “characterized by” or “tending to”. “Activate” is a verb formed from “active” and the suffix “-ate”， which means “to make something happen” or “to put into action”.
