My mother is usually mistaken for my sister，because she looks very young．．

Answer 1

分析 My mother is usually mistaken for my sister，because she looks very young．

解答 答案：My mother is usually mistaken for my sister，because she looks very young．．表達(dá)的是客觀事實(shí)用一般現(xiàn)在時(shí)．表示誤認(rèn)為mistake…for…，主語my mother是mistake的承受者，構(gòu)成被動(dòng)關(guān)系，故用一般現(xiàn)在時(shí)的被動(dòng)語態(tài)am/is/are+過去分詞，主語my mother三單，故is，usually 頻率副詞"經(jīng)常"，放在be動(dòng)詞后面，故My mother is  usually mistaken for my sister，表示因?yàn)椤�用because引導(dǎo)的原因狀語從句，she代替my mother，看起來look系動(dòng)詞，故looks，加上形容詞young年輕的，構(gòu)成系表結(jié)構(gòu)，very副詞"非常"，修飾young，故答案是My mother is usually mistaken for my sister，because she looks very young．．

點(diǎn)評(píng) mistake as…表示象．一樣的錯(cuò)誤，或者是類似．的錯(cuò)誤
mistake…for…是錯(cuò)把．當(dāng)作．
例句：
The student has made the same mistake as last time．
那個(gè)學(xué)生犯了和上次一樣的錯(cuò)誤．
