refer either to a prefix or a suffix) quite extensively. For example, the words “prefix,” “suffix,” and “affix” themselves are all formed from “fix” by the use of prefixes: “ad” (to) + “fix” (attached) = “affix” “pre” (before) + “fix” = “prefix” “sub” (under) + “fix” = “suff ix” Note that both the “ d” of “ad” and the “ b” of “sub” change the last letter. Here are some of the most mon Latin prefixes (for the meanings of the Latin roots, look up the words in a good dictionary): ab (away) abrupt, absent, absolve ad (to) adverb, advertisement, afflict in (not) incapable, indecisive, intolerable inter (between, among) intercept, interdependent, interprovincial intra (within) intramural, intrapersonal, intraprovincial pre (before) prefabricate, preface prefer post (after) postpone, postscript, postwar sub (under) submarine, subscription, suspect trans (across) transfer, transit, translate Affixes Morphemes added to free forms to make other free forms are called affixes. There are three principle kinds of affixes: 1. prefixes (at beginning) — “un ” in “unable” 2. suffixes (at end) — “ ed” in “walked” 3. circumfixes (at both ends) — “en — en” in “enlighten” (These always seem to consist of otherwise attested independent prefixes and suffixes.) 1 在歷史上 in the history of 2 成長(zhǎng) grow up 3 平均為 with an average 4 毫無疑問There’s no doubt of 5 一直 all the time 6 對(duì)。粗魯 be rude to 7 習(xí)慣于 be used to 8 引起某人注意 draw one’s attention 9 占有,占據(jù),擁有 take poession of 10 曾經(jīng),一度 at one point 11 如果有必要的話 if necessary 12 信任,信賴 rely on 13 保持紀(jì)錄 hold a record 14 以 。為基礎(chǔ) be based on 15 以。命名name…… after …… /be named after …… eg The villagers named the village after his name =The village was named after his name
