We are often warned by our teacher not to waste precious time, because time   (1)  will never return. I think it quite  (2)  What does time look like? Nobody knows for we can’t see it or   (3)  it and no amount of money can  (4)  it. Time is abstract（抽象的）, so we have to   (5)  about it.

    Time passes very quickly. Some students say they don’t have  (6)  time to review all their lessons. It is because they don’t know how to make  (7)  of their time. They waste it in going to theatres, cinemas and parks, and doing   (8)  things. Why do we study every day? Why do we   (9)  ? Why do most people would rather  (10)  buses instead of walking? The  (11)  is very simple. We wish to save time because time is  (12)  

    Today we are living in the 21st century. We look upon time as   (13)   When a person dies, his life   (14)   Since life is short, we must    (15)  our time and energy to our study so that we may be able to  (16)   the people well in the future. Laziness is the  (17)   of time, for it does not only bring us failure but also   (18)   us other harm. If it is necessary for us to do our work today, let us do it today and not  (19)   it until tomorrow. Remember that time is much more   (20)   than money.

All parents want to see their children succeed in life.

They want their children to have more than   (1)  they had, yet they often fail to give their children what is  (2)  needed.

Today’s children typically have their private   (3)  with a television, toys, cell phones, their own computers. When they come of age, they will even have their own   (4)  . Often, they do not treasure these as much as the previous generations did. Furthermore, they are sometimes more than just spoiled   (5)  these items give immediate satisfaction when they really need some attention. Gradually, they depend on these immediate distractions in order to relieve their 46  . Thus kids develop   (6)   attention spans with little patience.

    If   (7)  is a virtue, then why don’t parents   (8)   bring out the best in them?

    In today’s society, it is far   (9)  _ to entertain children than it is to instruct them in   (10)  development skills. In the current fast-paced society, parents choose to  52  _themselves with work in order to earn more and provide their children with a good living environment. They do not   (11)  enough time to play or communicate with their children. So parents can easily offer their children new toys  (12)  develop their children’s sense of duty which will lead their children through self-learning to understand the   (13)  of hard work and patience.   (14)  , the best method for parents to teach patience to their children is not by  (15)  them things, but by giving their children a(n)   (16)  to explore and learn about things that   (17)  them. Using this method, parents can eventually teach their children the same hard lessons that they have   (18)   learned too.

If you expect something to turn out badly, it probably will. But the same principle (原则) also   (1)   the other way. If you expect good things to happen, they   (2)   do. There seems to be a natural cause-and-effect   (3)   between optimism and success.

Optimism(乐观) and pessimism (悲观) are both powerful   (4)  , and each of us must choose one to shape our attitudes and our expectations. There are enough good and bad things in everyone’s life — sorrow and happiness, joy and pain — to find a(n)   (5)   for either optimism or pessimism. We can   (6)   to laugh or cry, bless or curse. It’s our   (7)  . From which aspect do we want to view life? Will we look up in hope or   (8)   in despair (绝望)?

An optimistic attitude is   (9)  . The way you   (10)   life will determine how you feel, how you perform, and how   (11)   you will be with other people. Thoughts, attitudes, and expectations   (12)   each other.

Optimism doesn’t need to be naive (天真的). You can be an optimist and still   (13)   that problems exist and that some of them are not dealt with   (14)  . But what a difference optimism makes is the attitude of the problem solver.

Optimism   (15)   our attention away from negativism (消极态度) and changes it into positive, constructive   (16)  . When you’re an optimist, you’re more concerned with problem-solving than with   (17)   complaining about problems.   (18)  , without optimism, problems as big as poverty have no   (19)   of solution. It takes a dreamer unlimited confidence to   (20)   a problem that is big. Which attitude you will choose is your choice.

 Unfortunately when people think of teenagers, good thoughts are not always the first to come to mind. I know I   (1)   going into my teenage daughter's high school at the end of their day because I don't want to be  (2)   in hallways. I feel like I am running the gauntlet (夹击) sometimes! I know they are   (3)  kids in a hurry to get out and go home as   (4)  as possible.

     (5)   I also get an opportunity to see teenagers at their best.   (6)   my daughter and her high school band's friendship is always a   (7)  . For instance, when a fellow band member's music file fell on the pavement, everyone ran to help   (8)   it up before it was blown   (9)   by the wind. They are a great group of kinds. But an event I witnessed yesterday really   (10)  my heart.

   My daughter had a band   (11)   at a nearby high school. Her band was the last one to play.   (12)   they could play their last selection, the lights in the hall flashed and then   (13)  . The atmosphere in the large, dark space was  (14)  . The band, sensing this, started singing some of the   (15)   songs that they had sung several times during football season. The   (16)   started clapping and singing along. Thinking about the experience - sitting in total darkness   (17)   and clapping with dozens of people like it was a(n)  (18)  happening.

   I was so   (19)  to be able to experience this firsthand. My daughter was a senior so this was one of her last   (20)   in high school. It was a moving inspirational experience I will never forget.

Food is very important. Everyone needs to  (1)  well if he or she wants to have a strong body. Our minds also need a kind of food. This kind of food is  (2)   . We begin to get knowledge even  (3)   we are very young. Small children are  (4)   in everything around them. They learn  (5)   while they are watching and listening. When they are getting older, they begin to  (6)  storybooks, science books... anything they like. When they find something new, they love to ask questions and  (7)   to find out answers. What is the best   (8)   to get knowledge? If we learn by ourselves, we will get  (9)  knowledge. If we are  (10)  getting answers from others and do not ask why, we will never learn well. When we study in the right way, we will learn more and understand better.

Recently we’ve discussed the idea of year-round schools. Students do not get a long break from   (1)   during the hot summer months.   (2)  , they get shorter breaks. Not very many schools in the United States do this. But other schools that are not year-round   (3)   often have summer programs.

In many cases, students take summer classes to   (4)   a subject they failed. This way they get a second chance to   (5)  . But schools also offer summer classes to students who want to be   (6)   of a required class during the next school year.

Generally, students in these classes want to take   (7)   subjects during the year because they are involved in a lot of activities,   (8)   sports or music programs. Or both -- and more. They do the same amount of work   (9)   they took the class during the school year. But they do   (10)   in a much shorter time, one to two months, and not much time for   (11)   else.

They say taking classes like these in the summer   (12)   they can take even more   (13)   classes next year. They say this shows colleges not only that they are   (14)   about their studies. It   (15)   shows that they have experienced the most difficult high school program possible.

  (16)   place with a lot of students in summer school is Palo Alto, California. About 20% of the students are in class this summer.   (17)   are in classes they failed before. The others are taking subjects they have   (18)   time for during the normal school year.

But they are not taking   (19)   like physics and history. The students in Palo Alto are in classes like creative writing,   (20)   studies, literature and cooking.

You may be surprised to see “making sure children never suffer” as a mistake. The following __36_ may help you understand how rescuing children from all suffering _37__ weakness.
   A little boy felt sorry for a butterfly struggling to 38   from its chrysalis(蛹). He decided to __39__the butterfly. So he peeled(剥开) the chrysalis open for the butterfly. The little boy was so _40  to watch the butterfly spread its wings and fly off into the sky. Then he was horrified __41__he watched the butterfly fall to the ground and die because it did not have the muscle __42_ to keep flying. In fact, the butterfly’s struggle to __43__ the chrysalis helps the butterfly become stronger.
   Like the little boy, __44__ too often want to protect their children from struggle in the __45__ of love. They don’t realize that their children need to struggle, to experience __46 , to deal with disappointment, and to solve their own problems. Only in this way can children __47 their emotional strength, become _48 and develop the skills necessary for the even bigger struggles they will meet throughout their lives. Children experiencing sufferings can __49_ the ups and downs of life.
   However, it isn’t helpful either in this case when parents __50__lectures(训斥),blame and shame to what the child is experiencing. Mothers __51__ to say, “Stop crying and acting like a spoiled boy. You can’t always get what you want.” These __52_ words should be avoided.
   Instead, parents can offer loving support. You can say, “Don’t lose __53__. Be brave! You will succeed if you try again.” Then comes the tough part — no __54__ and no lectures. Simply allow him to discover that he can _55  his disappointment and carry out what he can do to get what he wants in the future.

In our modern world, when something wears out, we throw it away and buy a new one. The    41  is that countries around the world have growing mountains of   42   because people are throwing out more rubbish than ever before.

How did we   43    a throwaway society? First of all, it is now easier to   44 an object than to spend time and money to repair it.    45 modern manufacturing (制造业) and technology, companies are able to produce products quickly and inexpensively. Products are plentiful and   46  .

Another cause is our  47 of disposable (一次性的) products. As  48  people, we are always looking for   49 to save time and make our lives easier. Companies   50  thousands of different kinds of disposable products: paper plates, plastic cups, and cameras, to name a few.

Our appetite for new products also  51 to the problem. We are   52 buying new things. Advertisements persuade us that   53 is better and that we will be happier with the latest products. The result is that we  54 useful possessions to make room for new ones.

All around the world, we can see the   55 of this throwaway lifestyle. Mountains of rubbish just keep getting bigger. To  56  the amount of rubbish and to protect the   57, more governments are requiring people to recycle materials.   58 , this is not enough to solve our problem.

 Maybe there is another way out. We need to repair our possessions    59  throwing them away. We also need to rethink our attitudes about   60 . Repairing our possessions and changing our spending habits may be the best way to reduce the amount of rubbish and take care of our environment.

The world would be a better place if we all had children’s eyes. This is not because children’s eyes are too sharp to allow any blot（污点,瑕疵）to pass without being  36 , but because adults have too many conflicting concerns to keep their eyes open to all wrongdoing.

Not long before, an examination, intended to  37  some police officers to higher positions, was held in Gansu province. Someone  38  with a good idea that 18 primary pupils could be invited to act as invigilators (监考人). At that age, students would do as they are told and act fearlessly.  39 , they caught 25 officers cheating on the spot, which has caused a stir (轰动,搅动) and  40  the question of whether adult invigilators would  41  their duties as well.

The implication of this event goes  42  its impact on the work style of local police officers and the examinations. Most people said what these children have done points to the sad fact of  43  being less trustworthy. If adults acted as invigilators, they would quite  44  turn a blind eye to cheating.

We Chinese have been holding the  45  that human nature was good at birth: as  46  of blot as a sheet of blank paper, which can be  47  with content (good or bad) in the process of growing up. Everything should be done on the basis of certain principles.  48 , nowadays the repeated reports of cheating in examinations, selling ranks and  49  and embezzling (挪用) public funds paint a  50  picture of common social morals. Adults have become too concerned with their own personal gains to  51  basic sense of principles. When no one  52  any principle and the only concern is personal interest, everyone will  53 , not only those who first break the rules.

Besides, cheats are unfair to honest examinees, and when the success of cheats  54  more people to cheat, the consequences will be disastrous.

In a word, we adults need to have our eyes as  55  as children’s on matters of principle.
