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 They include maps that are outdated, incorrect or difficult to understand.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.

    China has been the birthplace of many of the world's greatest inventions. It was, for example, the first country to produce paper money. Before the invention of paper money and coins, people used many different kinds of things for buying and selling. {#blank#}1{#/blank#} This exchange of goods and services for other goods and services is called bartering（物物交换）.

    {#blank#}2{#/blank#} In 1200 BC, people in China began to use shells as money. Usually the shells used as money were very small. This made it easier for people to carry money over long distances, and allowed for trade to develop between different parts of the country.

    In the years which followed this invention, many other countries around the world began to do the same. {#blank#}3{#/blank#}

    The next development was in 1000 BC, when China started making bronze and copper shells. It wasn't long before the Chinese made round coins out of metal. {#blank#}4{#/blank#} By 500 BC, metal coins had begun to appear in countries like Persia and Greece, and later in the Roman Empire.

    About 1000 years later, leather was used as money in China, and in 806 AD, the first paper banknotes were produced by the Chinese people. {#blank#}5{#/blank#}

B. People also began collecting foreign coins as souvenirs.

F. During that time, for example, buying a chicken might cost several potatoes.

G. The very first coins often had holes in them so that people could tie them together.

    Memory is our ability to learn something, save it and recall it when needed. Our memories are important to our sense of self, our personalities, and our ability to understand the world.

    {#blank#}2{#/blank#} There is short-term memory and long-term memory. Your short-term memory saves information for a few seconds or a few minutes. {#blank#}3{#/blank#} Long-term memory involves the information you try hard to keep, because it's meaningful to you-an example is data about family and friends. And then there is visual memory and sound memory. But these are not hard and fast. In fact, Scientists argue a lot about the nature of memory.

    {#blank#}4{#/blank#} Some memorize better with the help of pictures. Others are helped more by sounds. One thing's for sure though: If you can put the different kinds of memory together, there can be great results. {#blank#}5{#/blank#} At the same time, you could listen to recordings of the same group of words. These things may help when it comes to memorizing the words.

    Imagination and association can be useful too. By imagination, scientists mean picturing a word in your mind, while association means relating the word to something you already know.

A. So why not try pictures with English words?

B. Then how do chimps have better memories than us?

C. Scientists say that there are different types of memory.

D. We may have to rethink what we believe about human memory.

E. Scientists have also found that people memorize things in different ways.

    ●Does failure really exist? If you believe you have failed, then you have. If you believe you don't have the ability to succeed, then you don't.{#blank#}1{#/blank#}The moment you decide to give up or stop working toward your goals, failure is born.

    ●{#blank#}2{#/blank#}Most people give themselves an out without even realizing it. They are willing to work hard on reaching their goals, but only until the going gets too rough or their energy dies down. Don't do that!{#blank#}3{#/blank#}Never quit, never admit failure, and never lose heart.

Instead, get a general idea of when you'd like your goal to be completed.
