Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.

    {#blank#}1{#/blank#} First, we have most of our dreams during REM (rapid eye movement) sleep. At this time, the brain is very active. Second, everyone dreams, even if we can't remember doing so when we awake. {#blank#}2{#/blank#} While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.

{#blank#}3{#/blank#} Some believe that our dreams are relevant to thoughts and feelings that we experience while we are awake. Many dreams researchers think that a dream about death, for example, is really about an important life change. {#blank#}4{#/blank#} A dream about teeth—especially broken or loose ones-may suggest stress or fear. Dreams in which you are flying often represent freedom or escape.

   Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling, for example, maybe you are angry. {#blank#}5{#/blank#}

There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.

    A. Dreams may be more important than sleep.

    B. Scientists do not know for certain why we dream.

    C. If he or she was scared then maybe you are terrified of something.

    D. Modern research can tell us some important things about dreams.

    E. There are three things you should pay attention to have a sweet dream.

    F. Finally, a part of our brain helps us to understand daily experience we have.

    G. Dreams about telephones are thought to be about giving or receiving messages.

How to improve your happiness

    Recent research has shown that people who value their time over the pursuit of wealth are happier. So how can you best make, save and use your time — and ensure you keep a smile on your face?

● Pay someone to do the housework you hate

Why waste precious hours on housework or gardening if you can get someone else to do it?

● Set time limits on tasks you can't avoid

    Give yourself 20 minutes for necessary cleaning or 10 to hang out the washing. {#blank#}1{#/blank#}

● Enjoy standing in that queue

    With three people in front of you at the checkout, think about how busy you usually are and see the wait as a gift, not a bore(烦人的事情). {#blank#}2{#/blank#}

● Take on one new activity at a time

    {#blank#}3{#/blank#}At work and at home, be careful about the duties you take on. If you already feel stressed at work, don't do more at home.

● Learn to say no

    Be firm by declining a new project, or telling someone you can't talk right now or that you can only talk for a couple of minutes.{#blank#}4{#/blank#}

● Make lists your friend

    Start a wish list of the things you'd like to do and do more of the items that simply make you feel happy. Keep your daily to-do list manageable by putting it on an index card.{#blank#}5{#/blank#}

A. Be friendly but firm.

B. Make sure you start with an easy task.

C. This will get boring jobs out of the way faster.

D. Intending to do several things at once can be tiring.

Films and computer games

    In just a few decades the gaming industry has become much bigger than the film business. What is called "interactive entertainment" makes more money than Hollywood cinema. Is there any way of making films more appealing to people who like to play computer games?

    Making a film out of a best-selling computer game can guarantee a large audience. {#blank#}1{#/blank#} Nowadays films are made with similar ones. They have attractive action scenes relying on fantasy effects as well. Gaming markets consist of science-fiction games, and film-makers have also set films in science-fiction worlds. {#blank#}2{#/blank#} Any attempt to borrow more than the setting from a game is certain to fail.

Why do gamers feel disappointed by films based on their favorite games? One of the reasons is technical. Now everything can be computer-produced. {#blank#}3{#/blank#} However, filming a scene from 20 different cameras would cost a fortune, so it simply isn't done in the film version—leaving the gamers feeling that the film didn't look as real as the computer game.

    {#blank#}4{#/blank#} In a film the director doesn't show you some things to keep you have the feeling of excitement or anxiety. For example, you wouldn't be interested in watching the film if you knew the identity of the murderer. But this is not true for computer games. When you play a game, you have to do certain tasks to continue to the new level. {#blank#}5{#/blank#} You are always in control as a player, while in the cinema you never control the action. You just sit and watch.

    There can be some interaction between films and computer games on different levels. For all the similarities between technologies and special effects, we shouldn't forget that a story and a game are fundamentally different.

A. Cameras matter in another sense, too.

B. The success of a game usually lies in the use of special effects.

C. You can't influence what happens at all in the computer games.

D. Computer games may show the action from a number of views easily.

E. The game has a good chance of being as successful as the film on which it is based.

F. You must be able to have access to all the information in order to decide what to do next.

G. However, the difficulty for film producers appears to be knowing where and when to stop.

    The best way to set yourself up for success is to make sure that your goals are SMART: specific, measurable, attainable, relevant, and timely.

Make your goals specific.

    You need to give yourself a concrete goal so you know exactly what you're working toward. {#blank#}1{#/blank#}Who will be involved in helping you reach your goal? What exact goal do you want to accomplish? Be very specific. When will you start and when will you reach your goal?

Make your goals measurable.

    Now that you have some of the specifics of your goal nailed down, it's time to look at how you will measure your progress. After all, if you don't have any way to measure your goal, how will you know when you've reached it?{#blank#}2{#/blank#} Some examples of measurable goals might be pounds lost, a positive change in blood work numbers, or fitness minutes accumulated.

    Make your goals attainable.

    It's good to think big. {#blank#}3{#/blank#} A goal that's attainable for you is one that you believe you can reach and have all the support, equipment, knowledge and resources needed to put your goals into action.

    Make your goals relevant.

    You need to make sure that you're choosing a goal that fits you and your lifestyle. {#blank#}4{#/blank#}Pick something that is meaningful and relevant to you and you'll set yourself up for success.

    Make your goals timely.

    {#blank#}5{#/blank#}Otherwise, it will be difficult to know how to pace yourself to reach it. Every goal should have a date, which will help you stay on track. In addition, set up a few mini-deadlines to keep you on track to reaching your big-picture goal.

A. Put a deadline on your goal.

B. Never put off till tomorrow what you can do today.

C. You know your goal is specific if it answers these questions.

D. Therefore, you should know in advance how you will make this happen.

E. However, it's also important that you don't set a goal that is too big to reach.

F. Don't choose a goal just because someone else thinks it's something you "should" do.

G. Your goal is measurable if you can find a way to quantify your success using real numbers.

    3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and so on.{#blank#}1{#/blank#} Some scientists are trying to revolutionize the dining experience by doing this. They hope that having a 3D printer in the kitchen will become as commonplace as the microwave or blender. Scientists say that they are easy to use: {#blank#}2{#/blank#} You can also modify the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals.

    {#blank#}3{#/blank#}There would be less need for traditional growing, transporting and packaging processes as food production would be a lot more efficient.

    Printing food could also help people who suffer from dysphasia（言语困难）. They could program the printer to print softer versions of their favourite foods so that they would not have trouble swallowing them.

    However, some people think that a future of 3D-printed food would be a disaster. {#blank#}4{#/blank#}Imagine a world where there was no need for farming or growing crops and the same tastes and textures could be printed from a raw 'food ink'. Likewise, traditional cafes and restaurants might lose business.{#blank#}5{#/blank#} Is it really possible to get the nutrients we need from food-based inks and gels?

    What's more, cooking and eating together with family and friends will disappear. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

A. It will create many jobs.

B. It could take away many jobs.

C. Also, there are concerns about the nutritional value of printed food.

D. You simply have to select a recipe and put the raw food 'inks' into the printer.

E. Using 3D printers to create your meals would also be saving the environment.

F. But can you imagine printing food?

G. Printing food is great for your health.

Every New Year, thousands decide they're going to change their lives. Fewer than 10 percent actually stick with their plans, and that figure is being generous. {#blank#}1{#/blank#}.

Not aiming high enough. While it's easy to think setting easy goals will keep you motivated, it may harm your long-term motivation. If you make goals that are too achievable, you'll get bored and lose interest. {#blank#}2{#/blank#}. If you're used to staying within your comfort zone, you'll be missing out on the satisfaction of achieving a life-changing goal. When you push yourself, you'll be able to build unshakable confidence as you achieve goal after goal.

{#blank#}3{#/blank#}. This is a fear many of us deal with. Instead of taking action, we start worrying about " What if?" "What if it doesn't work out? What if my dream isn't truly my dream? What if I don't succeed?" If you have trouble creating a vision , then you're at the risk of being aimless through life. {#blank#}4{#/blank#}. You can start the process of discovering your life purpose by asking yourself, " What would my ideal life look like?"

A. Lacking self-confidence

B. Being uncertain about the future

C. Fortunately, fear can be overcome

D. Below you'll find some common reasons why you're losing motivation
