初三英语词根词缀记忆单选题30题1. The word "unhappy" means not happy. Here, "un -" is a prefix that ____.A. makes the word positiveB. changes the meaning to the oppositeC. has no meaningD. makes the word a verb答案：B。

解析：在单词“unhappy”中，“un -”是一个否定前缀，它的作用是改变单词的意思为相反的意思。

选项A中说使单词变为积极的，这与“un -”的否定意义相悖；选项C说没有意义是错误的；选项D说使单词成为动词也是错误的，“un -”在这里只是改变了“happy”的语义方向，所以答案是B。

2. The prefix "re -" in "rewrite" means ____.A. notB. againC. veryD. before答案：B。

解析：在单词“rewrite”中，“re -”这个前缀表示“再次”的意思。

选项A“not”是像“un -”等表示否定的前缀意义，与“re -”无关；选项C“very”不是“re -”的意义；选项D“before”也不符合“re -”的意义，所以正确答案是B。

3. The word "dislike" uses the prefix "dis -" which usually ____.A. makes the word more beautifulB. gives the word a positive senseC. changes the meaning to negativeD. makes the word a plural答案：C。

解析：在“dislike”这个单词中，“dis -”是一个前缀，通常它的作用是将单词的意义变为否定的。
