Be a Green Child

    What does it mean to be green? “Green” is more than just a color.{#blank#}1{#/blank#} Why green? Plants are green, and without them the Earth wouldn't be such a lovely home for us human beings. What can we do? Here's a four-step guide to being green.

    Reduce It!

    {#blank#}2{#/blank#} For instance, a shorter shower means you used less water and less fuel since your house uses to run the heater that warmed up the water.

    Reuse It!

    Sometimes people call ours a “throwaway society”. It means that we're a little to willing to throw away old stuff (东西) and buy new stuff.{#blank#}3{#/blank#}

    For instance, if your baby brother becomes older and loses interest in his plastic basketball hoop (篮圈), why not give it to another family who has a little kid?

    Recycle It!

    Recycling has never been easier. Many communities will pick it up right in front of your house and some towns even require it. Recycled goods go to a recycling center, where they can be turned into new cans, bottles, and paper.

    Enjoy It!

    It's true that rubbish and pollution are problems, but the Earth remains a huge and beautiful place that's ready for you to explore.{#blank#}4{#/blank#} Go for a hike, visit local nature centers and gardens, and climb up mountains.

    But before you travel the globe, take a look at your own backyard. Is there a spot where you could plant a tree or put in a little fruit or vegetable garden? {#blank#}5{#/blank#}

A. It also means taking special steps to protect the environment.

B. Many times, even if you no longer need something, someone else just might.

    For hundreds of years, people have been wondering about the strange places that they seem to visit in their sleep{#blank#}1{#/blank#}However, they have been valued as necessary to a person's health and happiness. Historically people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically believing that they tell about a person's characte{#blank#}2{#/blank#}He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.

    The second theory to become popular was Carl Jung's compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer{#blank#}3{#/blank#}Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.

    Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans{#blank#}4{#/blank#}Until they reach age five, they cannot express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance, the characters that appear in the dreams of men are often other men, and often involve physical aggression.

    The meaning of dreams continues to be difficult to understand{#blank#}5{#/blank#}If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.

A. Dreams make up for what is lacking in waking life.

B. However, people should not take their dreams as reality.

C. They have been considered as meaningless nighttime journeys.

D. It gives scientists chances to better understand human mind.

E. Children do not dream as much as adults.

F. They think their mind is trying to tell them something.

G. First, there was Sigmund Freud's theory.

    It's important to prepare for rainy days. Similarly, it's important to save money. {#blank#}1{#/blank#}Why? It's because they've got used to spending all the money they make. Sometimes, the hardest thing about saving money is just getting started. Here are some tips to help you save money.

    {#blank#}2{#/blank#}The first step in saving money is to know how much you're spending. For one month, keep a record of everything you spend money on. Once you have your data, organize these numbers by category(类别) and get the total amount for each.

    You can make a budget. Now that you have a good idea of how much you spend in a month, what can you do now? {#blank#}3{#/blank#} To plan your spending, you can build a budget. In this way, you can limit over-spending and make sure that you put money away for unexpected situations.

    {#blank#}4{#/blank#}Doing so make it much easier to get started. Begin by deciding how long it will take to reach each goal. Some short-term goals include starting a fund to cover 6 months to a year of living costs and saving money for a vacation. Long-term saving goals are often several years or even decades away and can include saving for retirement and putting money away for a child's college education.

    Make saving money easier with automatic transfers (自动转账). Automatic transfers to your savings account are very helpful. {#blank#}5{#/blank#}By moving money out of your checking account, you'll be less likely to spend money you plan to use for savings.

A. You can keep a record of what you do. .

B. You can record your costs.

C. You can plan your spending.

D. You can set savings goals

E. You can move money out of your savings account.

F. However, some people find it hard to save money.

G. They can make saving money much easier.

    Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resetting your body clock.{#blank#}1{#/blank#} Here's how to make one.

    ●{#blank#}2{#/blank#} In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reasons, tell your family or roommates about the change you want to make.

    ●Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags.{#blank#}3{#/blank#} That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

    ●Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found.{#blank#}4{#/blank#}

    ●Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you've tried a new method for a week, take a look at your record.{#blank#}5{#/blank#} If not, take another look at other methods you could try.

A. Get a sleep specialist.

B. Find the right motivation.

C. A better plan for sleep can help.

D. And consider setting a second alarm.

E. If the steps you take are working, keep it up.

G. Reconsider the 15 minutes you spend in line at the cafe to get coffee.

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. {#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day. {#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right. {#blank#}4{#/blank#}The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

    If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#} "You keep what matters," Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. Similarly, when people go for a few days without sleeping, they get sick.

D. The processes take place to stop our brains becoming loaded with memories.

E. That's why students do better in tests if they get a chance to sleep after learning.

F. "Sleep is the price we pay for learning," says Giulio Tononi, who developed the idea.

G. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

    I've always been interested in why we do the things we do, so last year I decided I'd like to study psychology. Most courses I found, however, were either too expensive, too long or were impossible to combine with work. I was about to give up {#blank#}1{#/blank#}.

    At first, I had no idea what they were talking about, but they explained that a MOOC is a Massive Open Online Course—a new type of course offered completely online to thousands of people, which is designed so that anyone can follow it, regardless of age, location or education—{#blank#}2{#/blank#}. You can search for hundreds of different subjects, and can usually watch a short introduction video to get an idea of what the course is about.

    {#blank#}3{#/blank#}. At first, I didn't know what to expect or how much time I might spend studying. Each week there were video lectures to watch and readings to do as well as some short assignments. The lectures were really interesting and easy to follow, and it was great to be able to watch them again or pause them to go and do something else. Most MOOCs have online forums (论坛), too, where students can discuss what they are learning. These are often really fascinating because there are so many different opinions, {#blank#}4{#/blank#}. If you read everything on the forums, you won't have time to finish the lectures!

    {#blank#}5{#/blank#}. There is a huge range of courses on offer in hundreds of subjects, and you have the chance to learn new things and be in contact with many different types of people, all from the comfort of your own home. Why not check out a MOOC and start learning something new today?
