For a long time I saw happiness as a huge banner (旗帜）across the finish line of a long race. I felt that only when I 36 _____ certain things could I finally be happy in my life. Most of the time I felt like a tortoise believing that being slow and 37 _____ would win the race. At other times I would 38 _____ like a rabbit trying different side roads at a dangerous 39 _____ hoping to reach that banner a little faster. 40 _____ , I began to see that no matter how long I raced towards it, the banner was never any 41 _____ I finally decided one day to 42 _____ and take a break. It was then that I saw my 43 _____ sitting beside me.
It had been with me as I 44 _____ hard to support my family, as I played with my children and heard their 45 _____ and even when I was 46 _____ with my wife at my side looking after me. It had been with me as I raced towards that stupid banner. I just didn’t have the 47 _____ to see it.
There is an old Chinese proverb that says, “Tension is what you think you should be. 48 _____ is who you are” Perhaps we all should stop our race towards the 49 _____ life we think we should have and 50 _____ the life we have now. Happiness will never be found under some banner far away. If will be found 51 _____ your own heart, soul and mind. It will be found when you 52 _____ that others love you just as you do.
Don’t be a tortoise or a rabbit when it comes to your happiness. Be a playful puppy and carry your stick of 53 _____ with you everywhere you go. 54 _____ yourself out of the race and realize that when it comes to love and happiness you are 55 _____ there.

Have you ever been at a meeting while someone was making a speech and realized suddenly that your mind was a million miles away? You probably felt sorry and made up your mind to pay attention and always have been told that daydreaming is a waste of time. 
“On the contrary,” says L. Giambra, an expert in psychology, “daydreaming is quite necessary. Without it, the mind couldn’t get done all the thinking it has to do during a normal day. You can’t possibly do all your thinking with a conscious（有意识）mind. Instead, your unconscious mind is working out problems all the time. Daydreaming then may be one way that the unconscious and conscious states of mind have silent dialogues.”
Early experts in psychology paid no attention to the importance of daydreams or even considered them harmful. At one time daydreaming was thought to be a cause of some mental illnesses. They did not have a better understanding of daydreams until the late 1980s. Eric Klinger, a professor of psychology, is the writer of the book Daydreaming. Klinger says, “We know now that daydreaming is one of the main ways that we organize our lives, learn from our experiences, and plan for our futures. Daydreams really are a window on the things we fear and the things we long for in life.”
Daydreams are usually very simple and direct, quite unlike sleep dreams, which may be hard to understand. It’s easier to gain a deep understanding of your life by paying close attention to your daydreams than by trying to examine your sleep dreams carefully. Daydreams help you recognize the difficult situations in your life and find out a possible way of dealing with them.
Daydreams cannot be predicated（预料）. They move off in unexpected directions which may be creative and full of ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy.

You may never connect the words “good” and “eco-friendly”with plastic.It’s time to do a rethink on that as we say hello to hemp(大麻)plastic.Traditionally,plastics have been made from petrochemicals,which are mainly poisonous.Plants,on the other hand,are also a source of cellulose(纤维素),which can be used to make biodegradable (生物所能分解的)plastic.As hemp happens to be one of the richest sources of cellulose,it is only natural that scientists will support its use,considering its ecological benefits.
Hemp plastic is biodegradable and recyclable.If you thought being eco-friendly reduced its solidity,you couldn’t be more wrong.The hard level of hemp plastic can match that of regular plastic.Hemp plastic is resistant to heat;however,the most outstanding feature of a few varieties of hemp plastic is that they are flame resistant too.Finally,if Henry Ford could imagine creating a car with this material,we can perhaps believe that it indeed is“ten times stronger than steel”.
It is a pity that with so many useful qualities,we don’t see hemp plastic being used in our everyday life,the way it ought to be.Hemp plastic can easily take the place of the exiting plastic in products like cell phone chargers(充电器),laptop covers,etc.Currently,hemp plastic is being used to produce audio(音响设备),video,toys,automobile parts and packaging materials.
Hemp fiber is one of the strongest natural fibers known to us.As scientists keep looking for ways to solve the ecological damage that traditional plastics have caused,here is a material that can be produced to be 100% biodegradable.Hemp plastic is known to be several times durable as compared to polypropylene(聚丙烯)plastic,and it comes without all the health and safety threats,It really has long useful life.
Plastics keep reminding us of the damage that we have done to our planet,all under the excuse of convenience.As hemp products have become a new choice into our daily life,Please take a green plan now and make your effort to protect the environment.
【小题1】Plastics produced in the traditional way are______.

You may picture firefighters holding a hose （水管） outside of a burning building，but the Golden Eagles Hotshots don't fight fires quite that way．When they go into action，you may not even see a fire truck．
The Hotshots are firefighters who battle fires in wilderness areas．But don't think you'll only find them in California．Wherever there is a national wildfire emergency，the Golden Eagles Hotshots could be there．
But these firefighters don't work the same way as those in big cities．They work where there are large numbers of trees，bushes，and grass．They climb up and down steep hills to clear brush and burnable debris （残骸）．They sometimes use water，but often fight fire with fire！
They do that by lighting what are called “backfires” ---- small，controlled fires that burn up fuel in the path of larger wildfires．That way, when the wildfire gets there, it has nothing to burn and nowhere to go，because all the burnable fuel has already gone up in smoke．
The Hotshots also clear away fuel using old-fashioned hard work．For example，they use a saw to cut away trees and heavy brush that could catch fire．
Of course there are times when the Golden Eagles Hotshots do have trucks to supply water to the fires．But the water is limited，and these guys have to rely on hard work more than anything．Physical fitness is very important．They have to be strong to handle steep hills while carrying a 60­pound pack．
Thanks to their efforts，many lives have been saved，many houses not burned，and countless trees still standing．
【小题1】According to the passage，why do the firefighters light “backfires”？

A．To signal for help．	B．To remove obstacles．
C．To protect trees and bushes．	D．To prevent the fire from spreading．

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.

"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.

The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.

Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.

The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.

Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.

We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
