编者的话
   如何正确理解和确切使用动词词组(v.+ prep. /adv.)在不同场合下的意义呢?这是学习英语的人难免遇到的棘手问题。一个动词词组是一个新的、单独的语言单位和概念,其意义已不同于组成这个词组的各个单词的总和,并且同一词组还可以具有多种意义。以look up为例动词look的愿意为眼睛动作的“视”或“看”,副词up的原意为“向上面”,但两者相结合成look up这一动词词组后,就可能有一下几种意义:
1.raise one’s eyes     抬头看,望眼看
   I was buried in my book, when I looked up, he had gone.
我埋头看书,当我抬头一望,他早已走了。
2.Improve, get better   好起来,看好
   Business is looking up these days.
这几天生意好起来了。(或:近来营业看好。)
3.try to find information about    寻找……资料(信息)
   Look up the word in a dictionary.
   此词可以查一下词典。
4.pay a call on; visit     拜访,探访
   Look me up the next time when you are in town.
   你下次进城可要上我这儿来。
   由此可见,这种“v. + prep./adv.”动词词组虽由常用简单词汇搭配合成,却同样能表达较复杂词汇和词组所表示的意义。因此,它在日常英语中极为广泛和活跃,是学习地道英语,特别是英语口语的重要内容。
   为使初学者及具有中等程度的英语学习者正确理解和学习这类动词词组,编者试图把具有同一小品词而意义相近或相当的动词词组归列一起,注释其内在涵义,通过练习,使读者便于把握他们意义上的相似性和联系,并有助于读者增强英语语感,较快较好地领会和运用动词词组。
   本书总收640个义项,以小品词(介词/副词)为中心归列内容,例如:以out为中心的其中一组就包括:drop out(撤退),get out(离开) give out(耗掉)leave out(除掉)pass out(失去知觉),through out(丢弃掉)等,各词组之间的涵义具有一定的相关含义,即都含有出自副词out(“分离”或“离开”)的意思。读者通过领会并实践这些小品词的含义,即使不查字典,也可根据上下文,推论或大致领悟出某一动词词组的意义。
   本书的编写简则是:
1.	本书选用的例句,体现日常生活内容,面广而词汇常用,因而比较实用,有利读者扩大英语词汇量,有助于开展日常会话。
2.	本书较多地采用了美国文章中的例句,使读者了解美国的某些风俗人情。
3.	每一词条均有相应的英语动词(或词组)注释和中文译义。鉴于例句比较简单,又为节省篇幅起见,例句的中文译义一律从略。
4.	各组例句均配有相应的填词练习,使读者有加深理解的机会。书后附有全部练习的答案。
5.	词条中凡插有“+”号者,表示该词组不可分。如:
        bring out                 (可分)
        bring + about             (不可分)
        get across                (可分)
        run + across              (不可分)
6.“v. + prep. /adv.”也可构成相应的复合名词或复合形容词。这类常用词汇作为附录,列于书后,以供参考。
  以小品词为中心,帮助读者对常用动词词组进行归类理解是编者的初次尝试,疏误和欠妥之处在所难免。诚希广大读者不吝指正。
