5.多使用正式规范的书面动词来替代具有 同样意义的口语化的动词或动词短语。 For example.,用 observe来代替 clook at, 用 examine 代替 check等 e.g PCR amplicons were examined by agarose gel electrophoresis

7.大量使用名词或名词短语。 of the genus Ascaris is of major pwe es e.g, Infection of humans with nematode health importance in a range of countries and affects millions of people 8.大量使用非谓语动词短语及分词短语。 These methods should provide valuable tools for studying the life-cycle and transmission pattern(s)of this parasite

9用I作形式主语,替代后面that所引导 的作为主句真正主语的从句。 It is well recognised that anisakids of some genera are transmissible to humans, where they can cause significant clinical diseases. 10.常用I作形式主语替代句子后面作真正 主语的动词不定式短语。 e.g., It is important to understand the life cycles of parasitic nematodes

11.多用介词词组来表示用什么方法、数 据、资料、什么材料、根据什么标准等。 e.g Characterisation of anisakid nematodes with zoonotic potential by nuclear ribosomal DNa sequences. 12.常见包含两个及两个以上从句的长句。 a previous study(palm et al.1998) has indicated that most parasite species of the Antarctic fish, Notothenia coriiceps, appear to be broadly distributed within Antarctic waters, which would correspond to a low host specificity in higher latitudes
