I Think I Can: How to Push Yourself to Success

    “Because I can” has magic power. It pushes us to leave our comfort zones. It gives us a reason to do the things that we think we can't. {#blank#}1{#/blank#}.

    {#blank#}2{#/blank#}.

    Whether it is to get to the store or work, climb the stairs instead of taking the elevator. Break the “I'm tired” or “It is too hard” or “It is too far” cycle. Increasing your activity level will provide enormous benefits, both physically and mentally.

    Try Something New

    It is easy for us to make excuses for why we shouldn't try new things.{#blank#}3{#/blank#}. Maybe it seems too difficult. Or maybe, it is just inconvenient. Reminding yourself that You Can try something new will help you to move past these roadblocks and discover new things about yourself and possible new interests.

Speak Up

    Often, we dare not address（处理）things that bother us or make us unhappy.{#blank#}4{#/blank#}.Use that voice “because you can.” Communicating to loved ones, co-workers, and even your boss as to how you feel, what your needs and expectations are and what you are thinking can help you develop deeper, more meaningful and rewarding relationships. Further, you will be truer to yourself, thus making you a happier individual.

Increase Your Willpower

    {#blank#}5{#/blank#}. However, developing a strong willpower, whether it is in response to our favorite chocolate cake or to over-shopping is something that we can all benefit from. Next time you are tempted to do something you think you might regret, try reminding yourself that you can say no. You have the power.

A. Saying “No” to our favorites can be challenging

B. Here are a few ways to apply this positive thinking to your own life

C. You have a voice

D. Be More Active

E. “Because I can” is an easy way to include more activities into your life

F. Maybe you think it is out of your comfort zone

G. A strong willpower can keep us motivated（有动机的）and reach our goals

    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（进化） 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 （神经突触）in the mice taken at the end of a period of sleep were 18 percent 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 sleep, 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(保存) 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(装载) 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.

    Are you truly happy? What does it mean to be happy? What does it take to achieve happiness? {#blank#}1{#/blank#} The following are a few tips that I follow to create happiness in my life.

    Make a plan for achieving goals that you believe will make you happy. Your moods (心情) will very likely increase if you are going after something you value.

    {#blank#}2{#/blank#} It is easy to begin to think negatively when you are surrounded by people who think that way. On the contrary, if you are around people who are happy, their emotional state will be infectious.

    When something goes wrong, try to figure out a solution (解决办法) instead of being absorbed in self-pity. Truly happy people don't allow setbacks to affect their mood because they know that with a little thought they can.

    Spend a few minutes each day thinking about the things that make you happy. {#blank#}3{#/blank#} And this will lead you to continuous happiness.

    {#blank#}4{#/blank#} Whether you treat yourself to lunch  take a long, relaxing bath or simply spend a few extra minutes on your appearance, you will be subconsciously putting yourself in a better mood.

    Finding the humor in situations can also lead to happiness. Find a way to make light of a situation that would otherwise make you happy.

    Keeping healthy is another way to achieve happiness. {#blank#}5{#/blank#}

A. Surround yourself with happy people.

B. There are some tips in life that lead to happiness.

C. Eating healthy foods or being fit can have a great effect on your mood.

D. These few minutes will help you focus on the positive things in your life.

E. What makes you happy may be different from what makes someone else happy.

F. It is also important to take some time each day to do something nice for yourself.

G. These are important questions for anyone who is seeking happiness to ask themselves.

    Next time your plane lands, listen to the sound of the tyres hitting the ground. {#blank#}1{#/blank#} The tyres of cars, motorbikes and trucks are also often made of the same stuff.

    {#blank#}2{#/blank#}Workers cut the trunks of the trees and collect a white liquid called latex（乳胶）. In the nineteenth and early twentieth centuries, huge numbers of rubber trees were planted in countries including Malaysia, Burma and Brazil. Nearly half the rubber which is produced each year is natural rubber and there is always a need for more.

    Rubber trees are not easy to grow. {#blank#}3{#/blank#} Some trees survive while others die and it is all decided by their genes. British scientists have been working together to look at rubber trees. They have now discovered the "genome" (基因组) of the rubber tree. {#blank#}4{#/blank#} The genome contains all the information the plant or animal needs to grow. The genome for a plant such as a rubber tree is smaller than a human genome but it is still very long, which is why it has been so difficult to find. Scientists say the work has been like putting a picture puzzle together where all the pieces show blue sea and blue sky.

    Now scientists can use the rubber tree genome to produce stronger trees. By understanding the genome, they can change the DNA in rubber trees in useful ways. {#blank#}5{#/blank#}

A. Natural rubber comes from trees.

B. Regretfully, many forests are being severely destroyed.

C. This is the way genes fit together in very long chains of DNA

D. Stronger trees have played a more important role in producing tyres.

E. They are affected by changes in temperature, rainfalls, winds and diseases.

F. The reason why the tyres don't explode is that they are made of natural rubber.
G. In the future, it will be possible to grow trees which survive climate change and disease.
