Ask three people to look out of the same window at a busy street corner and tell you what they see. {#blank#}1{#/blank#}(chance) are that you will receive three different answers. Each person sees the same scene, but each perceives something different about {#blank#}2{#/blank#}.

    Perceiving goes on in our minds. Of {#blank#}3{#/blank#} three people who look out of the window, one may say that he sees a policeman {#blank#}4{#/blank#}(give) a motorist a ticket. Another may say that he sees rush-hour traffic jam at the intersection. The {#blank#}5{#/blank#}(three) may tell you that he sees a woman trying to cross the street with four children. Perception is the mind's {#blank#}6{#/blank#}(interpret) of what the senses — in this case our eyes — tell us.

    Many psychologists today are working to try {#blank#}7{#/blank#}(determine) just how a person experiences or perceives the world around. Using a scientific approach, these psychologists set up experiments in  {#blank#}8{#/blank#} they can control all of the factors.  {#blank#}9{#/blank#} measuring and charting the results of many experiments, they are trying to find out what makes different people perceive  {#blank#}10{#/blank#}(total) different things about the same scene.

    No one knows {#blank#}1{#/blank#}(exact) how the earth began, as it happened so long ago. However, according to a widely {#blank#}2{#/blank#}(accept) theory, the universe began {#blank#}3{#/blank#}a “Big Bang” that threw matter in all {#blank#}4{#/blank#}(direction). For several billion years after the “Big Bang”, the earth was still just a cloud of dust.{#blank#}5{#/blank#} it was to become was {#blank#}6{#/blank#}(certain) until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so {#blank#}7{#/blank#}(violence) that it was not clear {#blank#}8{#/blank#}the shape would last or not. It exploded loudly with fire and rock. They were in time {#blank#}9{#/blank#}(produce) carbon dioxide, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water began to appear on {#blank#}10{#/blank#} surface.

    Chuck Wall teaches management and human relations at Bakersfield College.He walked into class one day and told his students that their homework was to perform{#blank#}1{#/blank#}simple and random act of kindness.Not{#blank#}2{#/blank#}(understand) the homework,the students didn't know what to do.Chuck didn't answer their questions.Instead,he encouraged his students to work it out by themselves.

    One week later the students entered.the classroom and began sharing their stories{#blank#}3{#/blank#}(excite).One reported on helping a poor dog abandoned by its owner.Another student told others about giving blankets{#blank#}4{#/blank#}to the homeless. Gradually,more and more students developed the habit of doing such kind acts,from{#blank#}5{#/blank#}they benefited a lot.

    Since then,similar kind acts{#blank#}6{#/blank#}(perform) in schools around the world.Many schools organize a.Random Acts of Kindness Week,around November 13^th,celebrated World Kindness Day.Some schools use each day of Random Acts of Kindness Week to perform such a different kind act{#blank#}7{#/blank#}making a new friend,helping someone,doing community{#blank#}8{#/blank#}(serve) or raising money for a charity.In this way,students learn to consider other people and think about{#blank#}9{#/blank#}small actions can make the world a{#blank#}10{#/blank#}(good) place.

    The world's fifth reported brown-and-white giant panda has been found in Foping Nature Reserve.{#blank#}1{#/blank#}(spot)on Nov.1,the baby panda, less than two months old, was estimated to {#blank#}2{#/blank#}(appropriate)weigh 2 kilograms and believed to be the fifth giant panda of this rarely seen color ever found.{#blank#}3{#/blank#}(it)eyes haven't opened yet, but it can sense the people {#blank#}4{#/blank#} come near it to take a picture.

    Many {#blank#}5{#/blank#}(research)believe the brown-and-white pandas are a return to the form typical {#blank#}6{#/blank#} their ancestors. But some argue that those pandas are a variation(变异)of their usual group while a few others think that they are {#blank#}7{#/blank#} new subspecies of pandas {#blank#}8{#/blank#}(result)from the environmental changes of the mountains.

    The first three recorded brown-and-white pandas {#blank#}9{#/blank#}(find)in Foping Nature Reserve, in 1985,1990 and 1991 with the fourth found in 1992 in Shaanxi. China has more than 2,000 giant pandas. The giant panda {#blank#}10{#/blank#}(feed)mainly on green bamboo.

    Cell phones can be life-saving communication tools to have on hand in a vehicle in case of emergency. {#blank#}1{#/blank#}, actually using a cell phone while driving may be life threatening. Many different studies have shown that when drivers use a phone while driving, it can be very {#blank#}2{#/blank#} (danger). At some point during the use of a cell phone, a driver's eyes are sure to be distracted from the road.

    Studies have shown that new drivers are especially likely {#blank#}3{#/blank#} (have) an accident when they use a cell phone while driving. The reason for this is {#blank#}4{#/blank#}new drivers have less experience in focusing {#blank#}5{#/blank#}driving during distractions. Also, several studies {#blank#}6{#/blank#} (do) on teen drivers found that many teens send text {#blank#}7{#/blank#} (message) while driving, which is thought to be more distracting and at risk.

    All drivers, not just teens or other new drivers, who use a cell phone while driving {#blank#}8{#/blank#} (say) by studies to be at least four times {#blank#}9{#/blank#} (much) likely to be at risk than drivers who don't use a phone behind the wheel. Such studies have inspired many countries, {#blank#}10{#/blank#} (include) the United States, to have at least some bans on hand-held cell phone use while driving. However, many people feel that these restrictions are not enough because studies have also shown that hand-held cell phones are just a part of the problem.
