Global Positioning System (GPS) is now a part of everyday driving in many countries. It is a space-based system that provides position and time information in all weather conditions. GPS can help people get to where they want to go.{#blank#}1{#/blank#}When this happens, the driver is often to blame. Sometimes a GPS error is responsible. Most often, it is a combination of the two.

    {#blank#}2{#/blank#}Barry Brown, a GPS technologist, took an incident as an example. His friend once flew to an airport in the eastern United States. There he borrowed a GPS-equipped car to use. He wrongly plugged in the home address in the west. It wasn't until he was driving for thirty minutes that he realized it. Mr. Brown says this is a common human error. But he says, “One problem is that GPS has a very small screen and it can just tell you the next turn.{#blank#}3{#/blank#}”

    “The Normal and Natural Troubles of Driving with GPS” lists several areas where GPS can cause difficulties. They include maps that are outdated, incorrect or difficult to understand. {#blank#}4{#/blank#}GPS may fail due to these reasons and then lead to confusion for the drivers.

    Although GPS sometimes causes difficulties when people are driving, the most attractive point of this system is its 100% coverage on the planet. It is important for you to have to know what you are doing when you use GPS. You need to have the “ability” to be able to use GPS because it sometimes goes wrong.{#blank#}5{#/blank#}

A. There are quite a few situations showing the problems of using GPS.

B. That means that it is not really telling you about going to the wrong place.

C. This space-based system is an important tool for civil and commercial users.

D. But sometimes it sends you to the wrong place or leaves you completely lost.

E. They also contain timing problems related to when GPS commands are given.

F. Advances in technology play an active role in modernizing GPS in many ways.

G. To make GPS well used, you need a good understanding of how drivers and GPS work.

    For as long as I can remember, I wanted to be a performer. But when it came time to go to college and decide what I wanted to be for the rest of my life, I didn't want to choose drama as my major. {#blank#}1{#/blank#} So instead of studying drama, I went to law school like my two sisters did before me. {#blank#}2{#/blank#} They worked about 80 hours a week, but they made good money and could afford expensive cars and apartments in the city.

    {#blank#}3{#/blank#} I had great benefits, including four weeks of vacation a year, but I never got to use any of my vacation time because there was always too much work to do. I worked from 7 a.m. to 9 p.m. six days a week, and when I finished, all I could do was get into my bed until I woke up to do it all over again the next day.

    After five years of this lifestyle, I thought I was going to go crazy. I was unhappy and exhausted, and I never saw my friends and my family. I thought that acting in a small community play might make me feel better, but rehearsals (排练) and performances all took place during my work hours. {#blank#}4{#/blank#}

    I got a small part in a local play, and then a bigger part, and then a lead role. Now I make my living from acting, and every now and then, I do some legal consulting (咨询) for a little extra money. {#blank#}5{#/blank#} I had to give up my big apartment and expensive car, but I'm so much happier now.

A. They aren't good examples to me.

B. They seemed happy enough, I thought.

C. I don't get paid a lot for my acting jobs.

D. So I made a serious decision and quit my job.

E. I am certainly a better performer than lawyer.

F. Making a living as a performer seemed impractical to me.

G. After law school, I got a good job and worked as a lawyer for a big company.

What will you do if you can't eat everything bought in the canteen(食堂)? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people. 

{#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people. 

Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the west, for instance, consumerism, the belief that it's good to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#}Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil (辛劳) others go through in order to provide them with the food they eat. 

{#blank#}4{#/blank#}There are 925 million hungry people in the world. They don't have enough food to eat. And farmers work very hard to grow the crops. {#blank#}5{#/blank#}It's also important that everyone thinks about how they can do their bit to reduce food waste. Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.
