3、ike to go to school from monday to friday.動(dòng)詞的單三形式變化規(guī)則:一般情況加 -s 清輔音后讀/s/ 濁輔音和元音后讀/z/ swim-swims；help-helps；like- likes以輔音字母+o結(jié)尾的詞加 -es 讀/z/goes,does以s,sh,ch,x等結(jié)尾的詞 加 -es 讀/iz/watches以輔音字母+y結(jié)尾的詞變y 為i再加es 讀/z/study-studies 不規(guī)則變化have和be動(dòng)詞變have 為 has 變be為am,is,arehave-has be-am,is,are2. 當(dāng)主語是其他人稱時(shí)，謂語動(dòng)詞要用原

7、160; carry-carried (3) 以重讀閉音節(jié)結(jié)尾的，雙寫最后的輔音字母再加edstop-stopped         drop-dropped          wag-wagged 2.不規(guī)則變化的動(dòng)詞過去式不規(guī)則變化是指過去式不能加ed，用另外一個(gè)詞來表示。這樣的不規(guī)則過去式也有很多，只有靠一個(gè)一個(gè)去記憶了。例如：is/am-was  are-were ha
