These days, breaking traffic rules and littering were not uncommon, causing serious harms to life and the environment. That requires lots of effort to change this situation on the part of everyone. As for me, I should start from little things and it won’t be long since I acquire good habits. If I ride a bike, I’ll always keep to the right but never cross a road until the traffic light turns green. If I walk, I’ll never forget use the pedestrian crossing. Meanwhile, I will regard it as my duty to help keep our environment clean and health. Not only will I keep myself on littering and spitting, I will also help clean up the roadside litter whenever be possible. I hope my behavior will make the difference.

The past is good for two things: the happy memories, and the lessons it provides. Take some time to think and create two lists: One, your Top Five Most Important Lessons Learned in the Year. And two, your Top Five Favorite Memories of the Year. 1.
Take some time to think
2. But you just invested 8760 or so hours of your life in the previous year. To pull what is worth pulling from it, to give it proper perspective and proper closure, it surely deserves some of your focused conscious energy.
3.
Maybe you lost half your investments this year. Or your job. Or your house. Or you faced health challenges. You may dwell on the negative, self-defeating questions like “How could I be so stupid?” or “How could God let this happen to me?” But a child doesn’t touch fire, get burned, and then spend the rest of his days – or even hours – thinking bitterly how this could have happened to him. He learns not to touch the fire and twenty minutes later he is happily playing again. 4.
Don’t bang on the beehive（蜂窝）
When discussing the past year I have already heard so many people stating how bad it was. I hear them recalling all the bad memories. It is like banging on a beehive. Because here is a universal law: whatever you seek, you will find plenty of. 5. Likewise, if you are focused on good memories, the beauty in the world, and things to feel grateful for, they will nourish your mind, your heart, and allow your life to blossom.
A. Learn from the past experiences
B. First and foremost, bear in mind that the key aspect of this experience is to “take some time to think”.
C. No matter how much you have invested, sometimes the healthiest thing you can do is let go.
D. In today’s go-go faster-faster world, you may be attracted to rush through this experience, to treat it like another task to get off your to-do list.
E. Remember the wisdom of a child
F. If you are focused on bad memories, problems, and things to complain about, they will drown your mind and your heart, and sting your life.
G. Now before you race off to do this, read the rest that provides important perspective on doing this.
When one tried to unify gravity with quantum mechanics(量子力学), one had to introduce the idea of ‘imaginary’ time. If one can go forward in imaginary time, one ought to be able to turn round and go backward. This means that there can be no important difference between the forward and backward directions of imaginary time. Yet there is a big difference between the forward and backward directions of ‘real time’ in ordinary life. Imagine a cup of water falling off a table and breaking into pieces on the floor. If you take a film of this, you can easily tell whether it is being run forward or backward. You can tell that the film is being run backward because this kind of behavior is never observed in ordinary life.
The explanation that is usually given as to why we don’t see broken cups gathering themselves together off the floor and jumping back onto the table is that it is forbidden by the second law of thermodynamics(热力学). This says that in any closed system disorder, or entropy(熵), always increases with time. In other words, it is a form of Murphy’s law: things always tend to go wrong! An intact cup on the table is a state of high order, but a broken cup on the floor is a disordered state. One can go readily from the cup on the table in the past to the broken cup on the floor in the future, but not the other way round.
The increase of disorder or entropy with time is one example of what is called an arrow of time, something that tells the past from the future, giving a direction to time. There are at least three different arrows of time. First, there is the thermodynamic arrow of time, the direction of time in which disorder or entropy increases. Then, there is the psychological arrow of time. This is the direction in which we feel time passes, the direction in which we remember the past but not the future. Finally, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.
1.How does ‘imaginary time’ differ from ‘real time’ according to the passage?
A. Imaginary time is more important than real time in science.
B. Directions mean less to imaginary time than to real time.
C. One can go backward in real time but can’t in imaginary time.
D. It is harder to tell directions of real time than of imaginary time
2.What’s the purpose of writing about a cup of water falling off a table?
A. To define the forward and backward directions of real time.
B. To tell the backward direction from the forward direction of real time.
C. To show real time is more scientific than imaginary time in ordinary life.
D. To prove there’s a big difference between the directions of real time.
3.Why don’t we see broken cups gathering themselves together off the floor and jumping back
onto the table?
A. It doesn’t agree with the second law of thermodynamics.
B. Things will quickly go wrong for entropy increases with time.
C. There is an interchange between a state of high order and a disordered state
D. All above.
4.The underlined word in the last paragraph is closest in meaning to ______.
A. universal B. physical
C. technological D. geographical
