Even when you’re extremely busy, you aren’t using your time with 100% efficiency. There are gaps in everyone’s schedule where they aren’t doing anything important. Even if your schedule has no gaps, there is probably lots of time when you aren’t working as fast or as effectively as you possibly could.
Why aren’t you completely efficient? It’s because time isn’t the limiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions (消遣). Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate (拖延) and slow down on tasks throughout the day.
The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you’re tired, you can have enough time and still not get everything done. Your attention ability is also limited, because even if there are a million things that need to be done, you can only focus on one or two at a time.
You might not be able to insert another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can add an hour or two into their schedule without cancelling anything. The reason why it’s hard to “find time” isn’t a lack of time. It’s because you don’t have enough energy left to focus on something else that needs to fit into your day.
I first suspected time wasn’t the real problem during an extremely busy period in my life over a year ago. I was extremely busy, but at that time I still exercised regularly. I had daily to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, I stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this odd experience? I believe you have known it.

“I’ve changed my mind．I wanted to have a telescope, but now I want my dad back．” Lucien Lawrence’s letter to Father Christmas, written after his father had been knifed to death outside his school gate, must have touched everyone’s heart．Lucien went on to say that without his father he couldn’t see the stars in the sky．When those we love depart from us, we cannot see the stars for a while．
But Lucien, the stars are still there, and one day, when you are older and your tears have gone, you will see them again．And, in a strange way, I expect that you will find your father there too, either in your mind or heart．I find that my parents, who died years ago, still linger （留連） in many of my dreams and that I think of them perhaps more than I ever did when they were alive．I still live to please them and I’m still surprised by their reactions．I remember that when I became a professor, I was so proud, or rather so pleased with myself that I couldn’t wait to cable my parents．The reply was a long time in coming, but when it did, all my mother said was “I hope this means that now you will have more time for the children!” I haven’t forgotten．The values of my parents still live on．
It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care．Would I have been as ready as Philip Lawrence has been to face the aggressors（入侵者）, and to lay down my life for those in my care? How many people would want me back for Christmas? It’s a serious thought, which gives me pause．
I pray silently, sometimes, in the dead of night, that ancient cry of a poet “Deliver my soul from the sword and my darling from the power of the God．” Yet I know death comes to us all, and sometimes comes suddenly．We must therefore plan to live together, but live as if we will die tomorrow．We live on, I’m sure, in the lives of those we loved, and therefore we ought to have a care for what they will remember and what they will treasure．If more parents knew this in their hearts to be true, there might be fewer knives on our streets today．
【小題1】According to the whole text we can see that the first paragraph ________.

A．puts forward the subject of the text

I have only once been in trouble with the law．The whole process of being arrested and taken to court was a rather unpleasant experience at the time, but it makes a good story now． What makes it rather disturbing was the arbitrary（隨意的）circumstances both of my arrest and my subsequent （隨后的） fate in court．
It happened in February about twelve years ago．I had left school a couple of months before that and was not due to go to university until the following October．I was still living at home at the time．
One morning I was in Richmond, a suburb of London near where I lived．I was looking for a temporary job so that I could save up some money to go traveling．As it was a fine day and I was in no hurry, I was taking my time, looking in shop windows, strolling in the park, and sometimes just stopping and looking around me．It must have been this obvious aimlessness that led to my downfall．
It was about half past eleven when it happened．I was just walking out of the local library, having unsuccessfully sought employment there, when I saw a man walking across the road with the obvious intention of talking to me．I thought he was going to ask me the time．Instead, he said he was a police officer and he was arresting me．At first I thought it was some kind of joke
But then another policeman appeared, this time in uniform, and I was left in no doubt．
'But what for?" I asked
‘Wandering with intent to commit an arrestable offence,' he said．
‘What offence?' I asked
'Theft,' he said
'Theft of what?'I asked
'Milk bottles,' he said, and with a perfectly straight face too!
'Oh,' I said．
It turned out there had been a lot of petty thefts in the area, particularly that of stealing milk bottles from doorsteps．
Then I made my big mistake．At the time I was nineteen, had long untidy hair, and regarded myself as pan of the sixties' 'youth counterculture'．As a result, I wanted to appear cool and unconcerned with the incident, so I said, 'How long have you been following me?  in the most casual and conversational tone I could manage．I thus appeared to them to be quite familiar with this sort of situation, and it confirmed them in their belief that I was a thoroughly disreputable （品行不端的） character．
A few minutes later a police car arrived．
'Get in the back,' they said．'Put your hands on the back of the front seat and don't move them．'
They got in on either side of me．It wasn't funny any more．
At the police station they questioned me for several hours．I continued to try to look worldly and familiar with the situation．When they asked me what I had been doing, I told them I'd been looking for a job．'Aha,' I could see them thinking, 'unemployed'．
Eventually, I was officially charged and told to report to Richmond Magistrates' Court the following Monday．Then they let me go．
I wanted to conduct my own defense in court, but as soon as my father found out what had happened, he hired a very good solicitor （律師）．We went along that Monday armed with all kinds of witnesses, including my English teacher from school as a character witness．But he was never called on to give evidence．My 'trial' didn't get that far．The magistrate （法官） dismissed the case after fifteen minutes．1 was free．The poor police had never stood a chance．The solicitor even succeeded in getting costs awarded against the police．
And so I do not have a criminal record．But what was most shocking at the time was the things my release from the charge so clearly depended on．I had the 'right' accent, respectable middle-class parents in court, reliable witnesses, and I could obviously afford a very good solicitor．Given the obscure nature of the charge．I feel sure that if I had come from a different background, and had really been unemployed, there is every chance that I would have been found guilty．While asking for costs to be awarded, my solicitor's case quite obviously revolved （回轉(zhuǎn)） around the fact that I had a 'brilliant academic record'．
Meanwhile, just outside the courtroom, one of the policemen who had arrested me was gloomily complaining to my mother that another youngster had been turned against the police． 'You could have been a bit more helpful when we arrested you,' he said to me reproachfully （責(zé)備地）．
What did he mean? Probably that I should have looked outraged （暴怒）and said something like, 'Look here, do you know who you're talking to? I am a highly successful student with a brilliant academic record．How dare you arrest me!' Then they, probably, would have apologized perhaps even taken off their caps, and let me on my way．
【小題1】Judging from the first paragraph, the writer's attitude towards his story is _______．

A．a(chǎn)ngryB．sad
C．a(chǎn)musedD．more than just one of the above
【小題2】The first man who came up to him was ______．
A．a(chǎn) uniformed policemanB．a(chǎn) policeman in plainclothes

A．the time for the trial was limited to fifteen minutes only
B．the author wanted to conduct his own defense in court
C．the case was dismissed before the trial reached that stage
D．he was found to be unqualified as a character witness
【小題4】The author believes that he would most probably have been declared guilty if _______．
A．the magistrate had been less gentle
B．he had really been out of work
C．he had been born in a lower—class family
D．both B and C

A．he had protested strongly at the time
B．he had begged to be allowed to go home
C．he hadn't wandered aimlessly
D．he had tried to look cool

John, a famous musician, took his priceless antique violin and played it in the crowded subway station. The music from the violin was delicately streaming throughout the whole station. However, during the one-hour play, only six or seven people were truly appreciating the charming music. A three-year-old kid was so fascinated by the music that he forgot everything around. John only got 52 dollars for his work that day.
However, in normal days, when John is about to hold a concert, one ticket can be sold at more than 100 dollars and it is extremely hard to buy a ticket even at such a high price. Therefore, later, many passers-by in the station that day felt deeply regretful for not recognizing the famous musician and missing such a valuable but cheap music feast.
I have a very busy friend who had totally changed after knowing that his wife came down with incurable illness. He cooked by himself for the family and took a walk with his wife every day. Nonetheless, his wife still did not manage to conquer the illness and passed away after three months. After that, he often sighed miserably that due to his past busy life, he had missed a lot of beautiful time with his wife. But now, it is impossible to make up for it.
It is no use crying over spilt milk. We have missed a lot of precious things in our life without knowing to cherish them.
Actually, I also missed something precious before. The reason why we would have missed those precious things is less than simple: we had thought that we could still own them tomorrow.
Nevertheless, tomorrow is actually by no means reliable. There was a famous Buddhist monk saying that in many people’s lives, they have only done two things: waiting and regretting. The result is that they were always too late to cherish what they had before they lost it. We would often claim to do something when we grow up, or when we have money or when we become old, etc. However, when we reach the condition we have expected, we could no longer realize our wish, because we have lost it by then.
【小題1】The reason why people often regret may be that _______.

A．they are too busy to notice the beautiful things
B．they are too careless to cherish precious things
C．they are lazy to observe the surroundings
D．they think that it’s none of their business
【小題2】The idea the author would like to get across to us seems that _______.
A．a(chǎn)ctions speak louder than words
B．a(chǎn) bad beginning makes a bad ending
C．the lost will never come back
D．each day brings its own bread
【小題3】What method does the author employ to support his opinion？
A．By listing data.B．By comparing the details .
C．By explaining the procedures .D．By taking examples.
【小題4】How do we understand the underlined parts “waiting and regretting”?
A．Many people will not cherish what they have until they lost them.
B．Many people cannot do well until they get older.
C．Many people know what they are doing.
D．Many people regret for what they don’t possess.

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步機(jī)). Sometimes they wore running shoes. Other times they ran barefoot (赤腳).
Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.
【小題1】What’s the main idea of the passage?

A．Walking in high heels could cause less serious effects than running barefoot.
B．Two new discoveries encourage people to run in high heels.
C．Running in shoes is partly good to runners.
D．Two new studies prove running without shoes is beneficial to runners in most cases.
【小題2】Which part of our body could be injured if we run in running shoes?
A．Toes. B．Hips. C．Feet. D．Legs.
【小題3】What can we learn from the passage?
A．The way that we run by landing on the front or middle of our foot could avoid damaging our heel.
B．We should start running barefoot in no time.
C．Running in modern running shoes could cause more serious effects than running in high heels.
D．We won’t be injured if we run barefoot.
【小題4】What is the writer’s attitude towards the use of the modern running shoes?
A．Persuasive. B．Negative. C．Objective. D．Supportive

Parents feel that it is difficult to live with teenagers. Then again, teenagers have        feelings about their parents, saying that it is not easy living with them. According to a recent research, the most common         between parents and teenagers is that regarding untidiness and daily routine tasks. On the one hand, parents go mad over         rooms, clothes thrown on the floor and their children’s refusal to help with the        . On the other hand, teenagers lose their patience continually when parents blame them for         the towel in the bathroom, not cleaning up their room or refusing to do the shopping at the supermarket.
The research, conducted by St. George University, shows that different parents have different          to these problems. However, some approaches are more         than others. For example, those parents who yell at their children for their untidiness, but         clean the room for them, have fewer chances of changing their children’s        . On the contrary, those who let teenagers experience the         of their actions can do better. For example, when teenagers who don’t help their parents with the shopping don’t find their favorite drink in the refrigerator, they are forced to         their actions.
Psychologists say that       is the most important thing in parent-child relationships. Parents should      to their children but at the same time they should lend an ear to what they have to say. Parents may       their children when they are untidy but they should also understand that their room is their own private space. Communication is a two-way process. It is only by listening to and       each other that problems between parents and children can be settled.

It is a tall tale that terrifies most young children. Swallow a piece of chewing gum and it will remain in your body for seven years before it is digested. An even worse tale is that swallowed gum can wrap itself around your heart.
But what does happen if you should accidentally eat a stick of gum? Chewing gum is made out of gum base, sweeteners, coloring and flavoring. The gum base is pretty indigestible一it is a mixture of different ingredients that our body can’t absorb.
Most of the time, your stomach really cannot break down the gum the way it would break down other foods. However, your digestive system has another way to deal with things you swallow. After all, we eat lots of things that we are unable to fully digest. They keep moving along until they make it all the way through the gut and come out at the other end one or two days later.
The saliva in our mouths will make an attempt at digesting chewing gum as soon as we put it in our mouths. It might get through the shell but many of gum’s base ingredients are indigestible. It’s then down to our stomach muscles一which contract and relax, much like the way an earthworm moves一 to slowly force the things that we swallow through our systems.
Swallowing a huge piece of gum or swallowing many small pieces of gum in a short time can cause a blockage within the digestive system, most often in children, who have a thinner digestive tube than adults 一but this is extremely rare.
【小題1】Children might feel terrified after swallowing chewing gum mainly because        .

A．they believe the tall tales about chewing gum
B．chewing gum will stay in their body for years
C．their heart will be wrapped by chewing gum
D．chewing gum is indigestible for children
【小題2】What happens to the food that can’t be fully broken down?
A．It remains in our digestive system forever.
B．It will be eventually moved out of our body.
C．It will fight against the power of the gut.
D．It will stick to the gut for one or two days.
【小題3】What would be the best title for text?
A．How does our digestive system work?
B．Can chewing gum be swallowed by kids?
C．Does swallowing chewing gum matter?
D．Why swallowing chewing gum frightens kids?

With petroleum reserves (石油儲(chǔ)量) decreasing，the search is on to replace gas with a cleaner，greener alternative.Though much eco－talk has centered on biofuels from corn and soybeans，the biofuel that looks more likely to replace petroleum comes from a most unlikely source：algae (藻類)．
Algae，like corn，soybeans，and other crops，grow via photosynthesis (光合作用) and can be processed into fuel oil.However，they yield 30 times more energy than land crops such as soybeans，according to the U．S.Department of Energy.Many algae species also can grow in saltwater and polluted water－while corn and soy require arable land and fresh water that will be in short supply as the world's population balloons.
“If you replaced all the diesel (柴油) in the U．S.with soy biodiesel，it would take half the land mass of the U．S.to grow those soybeans，”says Matt Caspari，chief executive of Aurora Biofuels，a Berkeley，Calif.－based private firm that specializes in algae oil technology.On the other hand，the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States，it would require 15,000 square miles，which is a few thousand miles larger that Maryland (12,407 square miles)，the 42nd state in land area.
Another bonus：Because algae can be grown just about anywhere in a closed space，they 're being tested at several power plants across the nation as a carbon absorber.Smokestack emissions (煙囪排放物) can be pumped directly into the ponds，feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles—is improving，it's still years away from reaching your local gas pump.“It's just a question of cost，because no large－scale facilities have been built yet，” Caspari says.
【小題1】The underlined word “yield” in Paragraph 2 can be replaced by “________”．

A．controlB．require
C．produceD．grow
【小題2】Compared with corn and soybeans，algae ________.
A．may pollute water and soil
B．can grow in poor conditions
C．provide much less energy
D．need more special care
【小題3】According to Paragraph 3，one of the advantages of algae fuel is that ________.
A．it can be used more widely
B．it is more easy to produce
C．it needs much less land
D．it costs much less money
【小題4】What do we learn about algae from Paragraph 4?
A．Algae help protect the environment.
B．People can grow algae anywhere.
C．Fish can get more oxygen from algae.
D．Algae produce less waste.
