【如题，感觉很是费解，请大家给解释下，谢谢】
对于worth这个词汇，初学者如果不注意词性（有形容词及名词的词性），就会出现混乱,它的表达结构是这样的：
●当worth是形容词时[名词前不可用，即不能作为定语用]: to be worth+后接名词、代词、数字或动词的-ing形式
（ 其实就是介词的用法），表示“值多少钱的；值得，值得去做”的意思。如：1. This car is worth about 4000 pounds.这辆车值大约 4000 英镑。（接数字）2. It was a long climb to the top of the mountain, but it was worth it for the view.虽然需要登很久才能到达山顶，但是能看到那样的美景，这一切都是值得的。（接代词）3. It is worth remembering that the last day for application is next Tuesday.值得记住的是，下周二是递交申请的最后一天。（接动名词）
●当worth是名词时，其结构常用的是：（金额、时间）+worth+of sth. 表示价值多少，或能用多长时间。题主提及的“be worth of sth
”结构，是不是记错了呢？4. The winner will receive ten pounds' worth of books.获胜者将得到价值10英镑的书籍。（金额）5. You've got three years' worth of research money to do what you want with.你有可维持3年的研究经费去做自己想做的事。（时间）6. A good interview enables candidates to prove their worth.好的面试可以让求职者证明他们的价值。(价值)7. The team would have need of a driver of his worth.这支队伍需要一位他这样技术水平的司机。（体现出价值））
我们来看看比尔.盖茨怎样用worth的？8. [ Computer] can store a lifetime's worth of photos, and they say, "I didn't know you could do that with a PC!" [电脑]可以存储你一生中有价值的照片，然后人们说：‘不敢相信个人电脑居然这么厉害！’
亲爱的，这个单词的学习关键在词性，其实，所有词汇的学习都要分清词性！
语言学习要遵循如下规律：■语言学习要从听开始，这样才能打通语音与文字之间的连接；■语言学习要以句子为单位进行输入输出，而非单词！这样去学，才能掌握单词的用法，这样去学，英语就会变得简单起来！■语言属于类运动型知识，仅仅背单词，看看书，刷刷题是远远不够的，需要去训练才能掌握！这跟弹钢琴的道理是一样的，看看书，看看乐谱就会弹钢琴？
