3.詳細(xì)解說
1.“be(not)good for…”意思是“對…(沒)有好處”,例如:Fresh fruit and vegetables are good for you.(新鮮的水果和蔬菜對你的
身體有好處。)Watching too much TV isn't good for you.(看太多電視對你沒有好處。)如果想表達(dá)“對…有害處”,則可以說“be bad for...”,例如:Smoking is bad for your health.(吸煙對你的健康有害。)Too much salt can be bad for you.(吃太多的鹽會(huì)對你的健康有害。)另外,口語中常會(huì)聽到“Good for you.”的說法,可不要想當(dāng)然地認(rèn)為它的意思是“對你有好處。”其實(shí)它是用來對某人的做法表示贊同的,例如:-I've decided to accept the job. -Good for you.(-我決定接受這份工作。-你做得對。)
2.在“Off to your homework now!”一句中“off”是副詞意為“離開,走開,遠(yuǎn)離”,例如:Are you ready? Off we go.(你準(zhǔn)備好了嗎?我們走。)I must be off now.(我得走了。)They were off to Italy and wanted to make an early start.(他們離開這里去意大利了,他們想早點(diǎn)兒開始。)
