而现代英语有一点比较奇特，英语中除了本族的词汇以外，还有大量的法语和拉丁来源的词，这就使得英语的同义词很多，而且这些同义词又不是通用的，这一点对于考生来说比较困难。环球教育小编觉得在选择这些同义词表达思想时，要注意分清主题，对象及情景。

     专业老师根据往年的TPO写作真题中的TPO词汇总结出托福写作高分的必要因素。包括准确的词汇和词组、严密的逻辑结构、有力的主题和论据等，而托福写作词汇使用也有着如下技巧：选词时要符合语言习惯并与社会文化诸多背景一致，选词时要考虑主题、对象及情景，应把握好英语和汉语词汇无法对应的部分。 　

     环球托福为考生带来一篇TPO真题高分范文，考生可以借鉴的同时将上述考试技巧回顾一下，看是否符合。

     The lecturer addresses each of the three criticisms of communal online encyclopedias mentioned in the Reading passage.

     The lecturer admits that communal online encyclopedias, like any reference book, may contain errors, but she claims that these errors can be corrected much more easily and quickly than those  printed in a paper encyclopedia. The Reading passage, in contrast, points to the inaccuracy of information in online encyclopedias, presenting the argument that errors in these resources are due to lack of professional knowledge among contributors.

     The lecturer then gives two strategies that have been proven very effective in protecting online encyclopedias from malicious alteration. She explains that contents that consist of indisputable facts are stored and presented in a read-only format so that nobody can make changes to them. In addition, she says, there are specialists who constantly monitor contents online so that they can quickly remove a suspicious change once it is detected.

     The lecturer also challenges the final point in the reading regarding the nature of topics covered in online encyclopedias. She says that because of virtually unlimited space on the Internet. there is no need to worry about what is important enough for inclusion in an online encyclopedia.

     Moreover, the greater variety of topics in online encyclopedias more truly reflects the genuine interests of the general public, even if some of these topics are less serious or academic than those in traditional encyclopedias.

     考生在练习托福写作时，对一些TPO词汇有意识的记忆一下，这样会有很好的学习效果。
