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 They include maps that are outdated, incorrect or difficult to understand.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

    The teenage years can be tough, and it's normal to feel sad every now and then. But if these feelings don't go away or become so intense that you can't handle them, you may be suffering from depression.{#blank#}1{#/blank#}

    Try not to isolate yourself.

    When you're depressed, you may not feel like seeing anybody or doing anything. Just getting out of bed in the morning can be difficult, but isolating yourself only makes depression worse.{#blank#}2{#/blank#}Spend time with friends, especially those who are active.

    Keep your body healthy.

    Making healthy lifestyle choices can do wonders for your moods. Ever heard of the "RunnersHigh"?

Any activity helps!{#blank#}3{#/blank#}As for food, make sure you're feeding your mind with plenty of fruits, vegetables, and whole grains.

    Avoid alcohol and drugs.

    You maybe try drinking or use drugs in an effort to escape from your feelings and get a "mood boost", even if just for a short time. However, substance use can make depression worse.{#blank#}4{#/blank#}You will need special treatment for your substance abuse problem.

{#blank#}5{#/blank#}

    Stress and worry can lead to depression. Talk to a teacher if exams or classes seem overwhelming. In addition,if you have a health concern you feel you can't talk to your parents about, see a doctor. A health professional can help you approach your parents and guide you toward appropriate treatment. If you're dealing with relationships, friendships, or family problems, talk to an adult you trust.

A. Ask for help if you are stressed.

B. Even a short walk can be beneficial.

E. In short, drinking and taking drugs will make you feel worse — not better — in the long run.

F. The more exercise you do, the healthier you will be.

G. Help is available and you have more power than you think.

    We all have to make decisions all the time, and we have an abundance of choices, ranging from tiny issues to vital ones. Unfortunately, people often find it hard to make decisions{#blank#}1{#/blank#} If you would like to improve your skill of decision making, here are four suggestions for you. Don't expect to have it all.

    {#blank#}2{#/blank#} You can't order every delicious dish on the menu. And there will be paths not taken, careers not chosen, to name a few. You can imagine some “what if' situations if you must, but do not let them take up too much space in your brain.

    {#blank#}3{#/blank#}

    It's often good to think through your decisions. But don't overdo it. Research can reach a point where returns begin to reduce, which makes it confusing more than clarifying. Many good decisions can be made based as much on intuition (直觉) as on careful assessment of endless data.

    Don't delay making decisions.

    Yes, there is a time to put off making a decision. Perhaps you need more information{#blank#}4{#/blank#} Or it's likely that you wait for a less stressful time. Just don't wait so long that the decision is made by your own indecisiveness.

    Don't be hard on yourself.

    You decide to go on a voyage. You choose an expensive liner. Everything should work out just right. Only you didn't expect a bug that ran around on the ship, making you and your family sick for five days{#blank#}5{#/blank#}But please remember it is unavoidable sometimes.

A. Don't spend too much time thinking.

B. It is an important source of information.

C. Don't count on emotion to make decisions.

D. Maybe you wish to consult with your advisor.

E. You may regret making such a stupid decision.

F. That means the skill of good decision-making counts a lot.

G. Decisions force us to close the door on other possibilities.

    Many countries have traditional dishes, made with special ingredients and prepared in a certain way. {#blank#}1{#/blank#}, and when tourists visit, these are the foods they want to try. But why are some foods more popular than others in certain areas?

Traditional ingredients

    Typical recipes (菜谱) are usually made with native plant and animal products. For example, Korean dishes often include rice and soybeans because both plants are native to East Asia and grow well in hot, wet areas. In contrast, wheat grows well in drier areas, like the Middle East, where bread is a common staple (主要的) food. {#blank#}2{#/blank#}, whereas inland cuisines tend to use more meat from farm animals.

    Food preservation

    Local cuisines often depend on how people traditionally prepared food for storage. In warm weather, meat and fish can go off quickly, so they must be cooked right away or preserved for later. {#blank#}3{#/blank#}, For that reason, modem Norwegian cuisine includes many smoked foods.

    Cooking techniques

    {#blank#}4{#/blank#}. In China, people often fry food in a deep metal pan or steam it in a basket over hot water. In Morocco, people cook traditional dishes in a special pot called a tajine, while in parts of India, people use a large oven, called a tandoor. And some local dishes aren't cooked at all.

    Imported (进口的) ingredients

    Sometimes local cuisines include ingredients that originally came from another place. {#blank#}5{#/blank#}, while many Russian dishes are made with potatoes. However, all of these ingredients were brought to Europe from South America in the fifteenth and sixteenth centuries. But now they are common around the world.

A. Seafood is often a key ingredient in coastal areas

B. There is a danger that local food traditions will be lost

C. Many different cooking techniques are used around the world

D. For example, Italian dishes often include tomatoes and peppers

F. Nowadays, we can buy food products from all around the world

E. These local dishes can become symbols of a place and its culture

G. In Norway, the Vikings used to “cure” meat and fish by smoking them over a fire

    {#blank#}1{#/blank#} When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, visions of country clubs and pleasure beats dance into view.

    The many wants of mankind might be regarded as making up several levels. {#blank#}2{#/blank#}

    The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. {#blank#}3{#/blank#}It included such items as automobiles and new houses.

    By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the "life-enriching" level. While the other levels involve physical satisfaction-the feeding, comfort, safety, and transportation of the human body-this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical care, and entertainment. {#blank#}4{#/blank#}

    On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

    A fifth level probably would involve wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. {#blank#}5{#/blank#}In this way, we can enjoy more fully the good things on the first four levels.

A. Then a third level appeared.

B. Human wants seem endless.

C. When there is money enough to satisfy one level of wants, another level appears.

D. There are several levels of wants in one's life.

E. At this stage, we now may seek to ensure the health, safety, and leisure.

F. Also included here are fancy foods and the latest styles in clothing.

G. Different people have different wants on each level.

    Many scientists believe our love of sugar may actually an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. {#blank#}1{#/blank#} In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.

    "It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar," says scientist Richard Johnson. {#blank#}2{#/blank#}Why? "Sugar, we believe, is one of the culprits, if not the major culprit," says Johnson,

    {#blank#}3{#/blank#}Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.

    So what is the solution? {#blank#}4{#/blank#} The trouble is, in today's world, it's extremely difficult to avoid. From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat.

    But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier options like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. {#blank#}5{#/blank#}

A. All tasty foods do this, but sugar has a particularly strong effect.

B. So many people have a sweet tooth.

C. One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes.

D. The battle has not yet been lost.

E. But the temptation seems hard to resist.

F. Our bodies are designed to survive on very little sugar.

G. It's obvious that we need to eat less sugar.
