My father bought a computer for me. (2)buy sth from sb意為“向某人買某物”。 He bought this watch from a friend.,(3)buy是短暫性動詞，在句中不能與時間段連用。將它改為have才可與時間段連用。 I have had the pen for two years. (4)sale為動詞sell的名詞形式。 on sale 出售，廉價出售 for sale 出售的，待售的，上市的,活學(xué)活用 When did you buy the computer? I have _this computer for 5 years，but it still works well. A.bought B. have C.had 解析C， buy 是短暫性動詞，若要和時間段連用，則要改為have。本句的“four five years”為時間段，故選C。,2. afford v. 負擔(dān)得起；買得起 點撥 常和情態(tài)動詞 can或be able to連用，常用于afford sth或afford to do sth結(jié)構(gòu)。 He cant afford (to buy) a car. I cant afford to go to a restaurant every day.,活學(xué)活用 Why dont you buy the computer? Its too expensive, I cant_it.

How many 用于提問可數(shù)名詞數(shù)量，后接可數(shù)名詞的復(fù)數(shù)，意為：多少 How many boys are there in your class? 你班上有多少位男生？,活學(xué)活用 ?Oh，$5Its very cheap AWhat time is it B How many do you want CHow much is it DWhats wrong 解析：從答語“$5”可以看出問句是對價格提問。 答案：C,真題解析,真題1 (涼山) John can play guitar，but he cant play chess Athe； B：the C the；the 解析：本題考查冠詞的用法。表示“彈奏樂器”使用定冠詞the，表示“下棋”不使用冠詞。 答案：A,真題2 (廣安) How much is the pair of shoes?
