四、重难点突破
1. 数字 zero—nine 的认读
本单元重点学习数字0到9的英文表达。数字在日常生活中非常常用,如密码、电话号码、学号等。注意区分形近的数字单词,如 three 和 five,six 和 seven。
例如:
0 — zero 1 — one 2 — two 3 — three
4 — four 5 — five 6 — six
7 — seven 8 — eight 9 — nine
【进阶训练】看数字,写出对应的英文单词
1. 3 ________ 2. 7 ________ 3. 0 ________ 4. 8 ________ 5. 5 ________
解析:1. three 2. seven 3. zero 4. eight 5. five
2. 询问密码的句型 What's the password?
用 What's the password? 询问密码是什么,回答用 It's… 后面接具体的密码内容。密码通常由字母和数字组成,读时逐个念出即可。
例如:
—What's the Wi-Fi password? 无线网密码是什么?
—It's r-o-o-p-3-2-n. 是r-o-o-p-3-2-n。
—What's the password? 密码是什么?
—It's 1-2-3-4. 是1-2-3-4。
【进阶训练】根据提示,补全对话

2. —________ the Wi-Fi password? —It's 5-6-7-8.
3. —What's the password? —________ z-x-y-9.
解析:1. password(询问密码)2. What's(What's the…句型)3. It's(用 It's 回答密码)
3. Can you say that again? 请求重复
当你没有听清对方说的话时,可以用 Can you say that again? 礼貌地请对方再说一遍。again 意思是「再;再次」。这个句型在对话中非常实用。
例如:
—What's the password? —Can you say that again?
—It's 3-6-9. —Can you say that again? —3-6-9.
【进阶训练】选择正确的答语
1. —What's the password? Can you say that again? 对方应该说: A. Thank you. B. It's 2-4-6. C. Good morning.
2. 你没听清密码,想请对方再说一遍,你应该说: A. What's this? B. Can you say that again? C. It's OK.
解析:1. B(对方应重复密码内容)2. B(礼貌请求对方再说一遍)
4. 设置密码的步骤
教材中介绍了设置密码的四个步骤:Step 1 Choose two words.(选两个单词)Step 2 Choose two letters from each word.(从每个单词中选两个字母)Step 3 Add two numbers.(加两个数字)Step 4 Put them together.(把它们组合在一起)设置密码时要注意:密码要 strong(强的)和 safe(安全的),不要用太简单的密码,并且要 keep it to yourself(保密)。
