unit6重点单词与句型
1 pleasure
n.高兴;愉快
【教材原句】一Can you help me think of an invention
你能帮我想一个发明吗?
—With pleasure !我很乐意!
【常见用法】pleasure 既可作不可数名词又可作可数名词。其作不可数名词时,意为“高兴;愉快”;作可数名词时,意为“乐事;愉快的活动/经历”。
It's a pleasure to read .阅读是一件乐事。
【联想拓展】在英语情景交际中,我们常会看到With pleasure 和It's my pleasure 这两种回答方式,它们的用法区别如下:
①With pleasure 意为“没问题;很荣幸为您效劳”,
通常只作为答应别人请求或邀请的答语。②lt's my pleasure 表示“不用谢;很荣幸为您效劳”,意为“不用谢”时,通常用在帮助别人之后,回答对方的感谢。
[典例]—Would you please come to the dancing party with me tonight
suppose we shall have a wonderful
night
A. Never mind
B. Have a good time
C. Not exactly
D. With pleasure
【解析】问句表达邀请,由答语后一句句意“我认为我们将会度过一个美好的夜晚!”可推知设空处表示“非常乐意去参加舞会”,应用With pleasure 。
【答案】D
