Physical education plays a vital role in the students' development and growth. According to recent medical studies, physical well-being of a student is directly related to his or her performance whether in class or in the office. {#blank#}1{#/blank#}

It's a link to good health.

    {#blank#}2{#/blank#} It's only in physical educational classrooms that students learn the value of taking care of themselves through proper grooming, healthy eating and regular exercise.

    Many doctors today agree that obesity is a serious health risk. Without any form of diet management and control with the numerous processed food students intake every day, a student's health can easily be at risk to many diseases. Physical education in school is a preventive measure to teach students the value of regular exercise.

It promotes academic learning.

    Physical health allows students to function better in classrooms. A good cardiovascular system developed from regular exercise promotes excellent blood and oxygen circulation. {#blank#}4{#/blank#} This circulation produces longer attention span during classes allowing longer concentration and absorption.

It builds self-trust.

    Students who are active in physical activities are more confident with themselves according to most social school studies. It's probably because of the self-discipline and dedication to excel in a sport that brings out the best in students. In school, the physical education program introduces these sport activities to students. {#blank#}5{#/blank#}

It promotes a physically active lifestyle.

    The purpose of physical education is to instill in students, at an early age, the value of self-preservation and choosing a lifestyle that is good for both the mind and body.

    Recently, children's literature has become more and more popular. In fact, children's literature has been welcomed by both children and adults. People have tried to find out why adults love children's literature just like children themselves {#blank#}1{#/blank#}.

    Children's literature is very different from adults' literature. Most of it is fantasy (幻想).{#blank#}2{#/blank#}. They can enjoy the fantasy world, which is never boring. The most important thing is that the world is bright and hopeful. In the fantasy world dead people can be alive again and broken legs can grow once more.{#blank#}3{#/blank#}.

{#blank#}4{#/blank#} When they read, their knowledge is increased and children know more about the truth. For a child who just learns to read, understanding the meaning of a word may be greater than learning the word itself.

    {#blank#}5{#/blank#} A large number of adults like it too. Not only young adults, parents and teachers, but also other people of all ages enjoys it. Both children and adults who love children's literature can get much pleasure from it.

A. Children can learn a lot from literature.

B. But there is no final answer.

C. Right always beats wrong in the end.

D. Children's literature is not only for children.

E. That means children can use their imagination.

F. What about the future of children's literature?

G. Children's literature can also influence children in education.

    Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir（嗡嗡声）of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.

    Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.

    Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.

    Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”

    Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”

    Steel is a hard metal that people use to make many different products. Car bodies, bridges, building frames, and containers are just a few of the things made from steel. {#blank#}1{#/blank#} But steel is better than iron in many ways. Steel is stronger but lighter than iron. Steel also lasts longer than iron.

    {#blank#}2{#/blank#}Then they add carbon to the liquid iron. They may also add other materials to make different types of steel. For example, steel with added chromium（铬）is called stainless steel. It will not rust（生锈）or stain. Finally, workers use machines to cool the liquid steel into bars or long sheets.{#blank#}3{#/blank#}

    People made the first steel as early as 1400 BC. Ancient people heated iron inside a pile of burning charcoal（木炭）. {#blank#}4{#/blank#}. The result was not the same as modern steel, but it was stronger than regular iron.

    In the 1800s people began to use huge ovens to make large amounts of steel. In the late 1800s builders used steel to make some of the first skyscrapers. {#blank#}5{#/blank#}. In the 1900s new processes made steel-making easier. Today steel remains one of the most popular building materials in the world.

A. This added carbon to the iron.

B. Steel is quite different from iron.

C. The hardened steel may then be made into products.

D. Steel is basically iron mixed with a little carbon.

E. Then they will be cooled and put on the market.

F. To make steel, workers hear iron until it melts.

G. They also used steel to make large, modern bridges.

    The most successful people all have certain habits in their daily routines. These habits help contribute to their success. Forming a new good habit can be a struggle, but it is well worth the effort. {#blank#}1{#/blank#}

    Set your goal. Before you can begin to work on your new habit, figure out exactly what you hope to accomplish. {#blank#}2{#/blank#} Make sure that your goal is specific, measurable and realistic to increase your chances of success.

    {#blank#}3{#/blank#} Choosing the habits that are most likely to help you achieve your goal is important. After you have set your goal and worked out all the specifics of achieving that goal, identify a habit that is part of achieving that goal. Consider what good habit would help you accomplish that goal.

    Consider your motivation. Once you have identified your goal and the new habit you need to accomplish this goal, take some time to consider your motivation. {#blank#}4{#/blank#} Good motivation can be the difference between success and failure in terms of forming a new habit. So take your time to consider your motivation.

    Give yourself time. Forming a new habit can take a long time. Some people can form a new habit in as little as a few weeks, while other people will take several months. As you work to form your new habit, just keep in mind that it may be a while before it comes true. {#blank#}5{#/blank#}

A. Identify ways to achieve goals.

B. Find the habit you want to form.

C. Good habits are sure to make you a success.

D. Here are the four steps you can follow to form good habits.

E. It is worthwhile to consider your goal.

F. Try to be patient with yourself as you form your new habit.

G. Your motivation is the reason you want to form this new habit.

Help Migrant Workers

    There is nothing like going home. More so if it is for the Spring Festival family reunion. For a migrant worker it perhaps means even more. To be able to set out on a homeward journey with money from a year's toil in his pocket is the best thing he can think of. {#blank#}1{#/blank#} They had to press hard for their defaulted payments, the salaries that were failed to pay up.

    About 200 million migrant workers nationwide are something left behind by economic reforms and opening up due to their contributions in the past three decades. It is almost impossible to imagine life in these places without them. However, they still form a disadvantaged group. Their rights are violated in different forms. Among other things, unpaid salaries are the most painful of such violations that are likely to drive a migrant worker to desperate actions. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}They have taken measures to prevent employers from holding back payments to them. Yet, as the financial crisis bites deep, some small enterprises that are struck the most try to reduce their economic losses by laying off migrant workers or refusing to pay them. So it is particularly important for governments at all levels to do an even better job in helping villager-turned-workers recover their unpaid salaries before the Spring Festival.

    It is good news that quite a number of local governments have organized special taskforces to conduct inspections in those labor-intensive enterprises to make sure they have paid their migrant workers in a timely and fair manner. Construction commissions in almost all provinces have published hotlines for farmer-turned-construction workers to lodge complaints against their employers for withholding their salaries.  {#blank#}4{#/blank#} But we need to look for solutions that will work at all times. We need to put in place a mechanism that will effectively prevent employers from holding back salaries to workers.

A. Some have reportedly climbed up chimneys to jump to their death unless they get their defaulted salaries.

B. It is something every Chinese look forward to as the traditional gala draws near.

C. Unfortunately, weeks preceding the Spring Festival have turned out to be hard times for migrant workers.

D. Hopefully, these efforts will send more workers on a happy journey home for the Spring Festival with their salaries in their pockets.

E. However difficult the situations they are in, it is too cruel and unfair for employers to hold back salaries they should pay their migrant workers.

F. Objectively speaking, governments at various levels have done a great deal in helping these workers recover their defaulted salaries.
