1. Mario, you used to be short, didn't you 马里奥，你以前个子矮，是吗？
（1）本句是反意疑问句。原则：前否后肯；前肯后否。
反意疑问句（两部分构成：陈述句（前半部分）+疑问句（后半部分））
①肯定陈述句＋否定提问　（前肯后否）
e.g.: Lily is a student, isn’t she Lily will go to China, won’t she
②否定陈述句＋肯定提问 （前否后肯）
e.g.: She doesn’t come from China, does she
You haven’t finished homework, have you
③提问部分用代词，而不用名词
e.g.: Lily is a student, isn’t she
④陈述句中含有否定意义的词，如little, few, never, nothing, hardly等。其反
意疑问句用肯定式。
e.g.: He knows little English, does he 　 他一点也不懂英语，不是吗？
They hardly understood it, did they 他们几乎不明白，不是吗？
（2）used to do sth. 意为“过去常常做某事”。
e.g.: Tim used to play lots of computer games, but now he works hard for his dream.

2. It's been three years since we last saw our primary school classmates.

e.g.: It has been ten years since I began to learn English.
=It is ten years since I began to learn English.
【注意】：since作连词时，意为“自从；自……以来”。主句常用完成时，且动词需用延续性动词。since后面接的从句要用一般过去时态。相当于“for+一段时间”，对应的主句是相应持续性动词的完成时态。
e.g.: It’s been 3 years since my grandma passed away.

V、阅读短文，并按要求完成下面的问题。（10分）
Blind people used to get around with the help of a walking stick. They tap it along the ground as they move. At the same time, dogs are trained to help them, too. These guide dogs lead blind people through busy areas. When blind people are in a new place, they can ask others for directions. Then they pass on the information to the guide dog by using the right orders.
Now there is new technology that can help blind people when they are in a new place. It is GPS. GPS stands for Global Positioning System. GPS can tell a blind person exactly where he or she is, It uses satellites (卫星) in pace to wok.
Blind people who use GPS carry around a tiny receiver. The tiny receiver works like a talking map! First, the receiver gets signals (信号) from satellites in space. Then, a computer guides the user with voice orders. Finally, the user listens for exact directions.
GPS also lets people know what is around them. It tells the name of the street that is coming up, It may even tell the user about a park or store nearby. Blind GPS users have a
better idea about their neighborhood. They feel better about traveling alone. They feel good about getting to new places.
Some scientists noted that GPS still has room for improvement. For example, GPS will call the police as soon as possible when the blind people have an emergency in the future. We all hope that the blind people will live like healthy people with the help of GPS.
