英语课后词汇的含义意思是词汇的内涵意义吗

你这个问题有点难理解。英语课后词汇注释的意思基本上都是这个词汇在课文语境中的意思，而不包含这个词汇的其他意义。教材和词典的不同就在这里，教材提供的是一个范例，从教材里面，你可以学到语言习惯和词汇在具体语句中的用法，但是，你想知道词汇含义的变化等等，就要借助词典。

英语写作 学习英语的重要性和有效的方法

Nowadays,people won't fuss about the importance of English learning,for the number of English learners is skyrocketing.Nonetheless,what makes English so critical ?My reasons come as follows.
In the first place, English is the most widely used language in the world,nearly 500 million people taking it as their official language,which makes English popular among many countries.In addition, some of the English speaking countries have economic advantages over other countries;consequently, their culture,history,politics,even military, have made a far-reaching effect on others.As a bridge which is used for communications,English is hard to be substituted.Above all,since globalisation has played a leading role around the world, English learning is no more just a kind of avocation,but a vocation which helps to boost the economy of non-English speaking countries.
Now that English does make a big difference, how can we learn it well? Speaking for myself, I think there are three methods we need to bear in mind.First of all, we should speak English as often as possible. Language is always used for speaking,if we can't speak it ,then we can't really understand it.Second,read more and watch more.it's not easy to read original versions of English materials at first.However,if you can keep trying and struggling,you'll find it the most efficient way to enter the English world. At last,we're supposed to be a good observer.Never let the words go if you don't get it.Never let the sentences go if you can't understand its structure.In a nutshell, learning English needs time,effort, grit and planning.No one can build Rome in one night!
