1、Section B(1a-1e),任务:用方框内所给单词填空,buy go make borrow use clean take invite,1. buy some drinks and snacks 2. make your bed 3. clean your room 4. invite my friends to a party 5. go to the store 6. use your CD player 7. borrow some money from me 8. take out the rubbish,buy some drinks and snacks 买一些饮料和小吃

2、剖析 buy作及物动词, 意为“买, 购买”, 其过去式、过去分词都是bought。 拓展 buy表示“买”时, 可带双宾语, 若双宾易位, 通常要用for, 即:buy sb.sth.= buy sth.for sb.给某人买某物。 I bought my son a toy car yesterday. = I bought a toy car for my son yesterday. 昨天我给儿子买了一个玩具车。 buy表示“从买某物”时, 通常用介词from, buy sth.from.“从某人(那儿)或某地买来某物”; 其反义词组为sell sth.to.意为“将某物卖给某人或某地”, 且两者可以进行同义句转换。 He bought this watch from a friend. 他从一位朋友那儿买了这块手表。 =A friend sold this watch to him.一位朋友把这块表卖给了他。,buy表示“用多少钱买某物”, 通常用介词for, 有时也用介词at, 侧重指价格。 I bought the computer for $600. 我花600美元买了这台电脑。 He bought them for/at 10 dollars each. 他以每个10美元的价格买下了它们。,
