如果让学生用英语表达“河北雷庄今晨发生里氏六级地震 ,天津部分地区有震感”这样一个信息 ,学生最感困难的并不是单个的词 ,比如“里氏”、“地震”等 ,而是词组 ,如“发生地震”、“里氏六级地震”、“有震感”。因为单词查一下汉英词典就能解决 ,但这类词组因不符合一般汉 If students are allowed to express in English an information that “Hebei Leizhuang had a magnitude of 6 on the Richter this morning and some parts of Tianjin have a sense of quake”, the most difficult problems for students are not individual words such as “Lee’s” or “earthquake”. It is a phrase, such as “the occurrence of an earthquake”, “the sixth grade earthquake on the Richter scale”, “there is a sense of shock”. Because the word can be solved by checking the Chinese-English dictionary, this type of phrase is not suitable for ordinary Chinese.
