re-是最常用的前綴之一。它可以加在名詞或動詞前面，構(gòu)成新的名詞或動詞。re-表示以下三方面的意義：

(1)表示“回”或“向后”的意思。例如：return（回來）、recall（回憶，召回）、retract（縮回，取回）。(2)表示“再”、“重新”、“重復(fù)”的意思。例如：rethink（再思考）、reuse（再運用）、restart（重新開始）、recycle（再利用）。(3)表示“相反”、“反對”的意思。例如：rebel（反叛，謀反、reverse（反轉(zhuǎn)，顛倒）、resist（反抗，抵抗）。2.un-前綴，常加在形容詞、副詞、分詞、動詞和名詞之前；第一，表示否定意義。第二，表示“反動作”。即“相反的動作”。例如：uneconomic不經(jīng)濟(jì)的、uncomfortable不舒服的、unending無盡的、unfortunate不幸的、unusual不平常的、unkind不仁慈的、unbind解開，釋放、uncover揭開……的蓋子、unearth由地下掘出、unbutton解開鈕扣。3.-ive是形容詞后綴一般表示有......的create﹢-ivecreative4.recent﹢-ly

recently形容詞加ly變副詞special和especial是同義詞,especially是especial的副詞。5.后綴-tion附在動詞后面構(gòu)成名詞1)當(dāng)單詞最后是t、d、te、de時，變名詞加ion或者ation、ition；protect﹢-ionprotection2)當(dāng)單詞最后是元音字母時，變名詞加sion等。Makealistofthingsthatneedtobedonetosavetheenvironment.Whichthingscanbedonebycommonpeopleeveryday?Whathavetobedonebygovernmentsandorganizations?Discussthesewithyourgroup.2e●turnoffthelightswhenyou●
