Research has become both simpler and more complex. It's simpler because, {#blank#}1{#/blank#} you have computer, you can find information you need by searching the Internet. For all you information, you don't have to go to {#blank#}2{#/blank#} library to find the relevant resource and take notes on it. Instead, you can find some sources from the Internet {#blank#}3{#/blank#} print the copies needed. Remember, however, that you should usually consult different types of sources. That is, you {#blank#}4{#/blank#} always rely just on the Internet for you research.

        While findinginformation is easier than ever, at the same time, researching has become {#blank#}5{#/blank#} complex. There is a lot more material available, which means you may be overwhelmed {#blank#}6{#/blank#} the amount of information. You need to learn {#blank#}7{#/blank#} to sort through and find the relevant information for your particular project. Also, {#blank#}8{#/blank#} need to check the accuracy of it.

If the population of the Earth keeps on increasing at its present rate, there will eventually not be enough resources {#blank#}1{#/blank#} (leave) to support life on the planet. By the middle of the 26^th century, if present trends continue, we {#blank#}2{#/blank#}（use）up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on the earth will make{#blank#}3{#/blank#} necessary for us to look for open space somewhere else. But {#blank#}4{#/blank#} of the other planets in our solar system are capable of supporting life at present. One possible solution {#blank#}5{#/blank#} the problem, {#blank#}6{#/blank#}, has recently been suggested by an American scientist, Professor Carl Sagan. Sagan believes {#blank#}7{#/blank#} before the Earth's resources are {#blank#}8{#/blank#} (complete) exhausted it will be possible to change the atmosphere of Venus and therefore create a new world almost as large as the Earth {#blank#}9{#/blank#}.The difficulty is that Venus is much hotter than the Earth. {#blank#}10{#/blank#}, there is only a tiny amount of water there.

    Is there such a thing as being “over-protective”?

    I can honestly say that my answer{#blank#}1{#/blank#}that question has changed dramatically（戏剧性地）since I became a parent.

    Before the birth of my daughter,I taught at a private school,often{#blank#}2{#/blank#}(view) my students as over-protected, worrying{#blank#}3{#/blank#}would happen to them when they went on to middle schools.

    Some did fine,and some did not.Some needed constant pats on the back,words of encouragement and extra support,which I{#blank#}4{#/blank#}(happy) gave.Others{#blank#}5{#/blank#}(satisfy) with themselves,needing little or no interaction（互动）with their teacher.{#blank#}6{#/blank#}for the most part,graduates would go on for higher schooling.

    I'd always taken it for granted{#blank#}7{#/blank#}their parents were over-protective,for they were the ones that still walked their{#blank#}8{#/blank#}(five) graders into the classroom and met them at the school gate.

    Admittedly,I laughed at those parents,thinking their children would never learn to be{#blank#}9{#/blank#}(dependent) if they didn't let go just a little.Then I had my own daughter. The moment I looked at her little face,I knew I'd do everything in my power{#blank#}10{#/blank#}(protect) her and make sure she always felt safe!

    Marty is a disabled boy{#blank#}1{#/blank#} suffers from a muscle disease. Sometimes he is too weak{#blank#}2{#/blank#}(run) or climb stairs as quickly as other people. The doctors don't know {#blank#}3{#/blank#}(exact) what is wrong with him. Luckily, Marty has learned to adapt {#blank#}4{#/blank#} his disability. In order to make his life happy and{#blank#}5{#/blank#} (satisfy), Marty keeps busy doing things that do not require physical strength. He has friends with {#blank#}6{#/blank#} he can go to movies and football matches and he has lots of pets. He used to dream of one day being a famous football player and {#blank#}7{#/blank#} (represent) his country in the World Cup. Even when he is made fun of, he doesn't get {#blank#}8{#/blank#} (annoy). Disabled{#blank#}9{#/blank#} he is, Marty has become stronger and more independent. He never feels sorry for himself and he enjoys as rich and full a life as everyone else.

    He suggests that we normal people should give the disabled {#blank#}10{#/blank#} (encourage) rather than laugh at them.

    Strange things happened {#blank#}1{#/blank#} Tangshan Earthquake happened. The well walls had deep cracks. A smelly gas came out of them. The water pipes {#blank#}2{#/blank#} (crack) and burst. At 3:42  {#blank#}3{#/blank#} the morning of July 28, 1976, everything began to shake. It seemed as if the world was at {#blank#}4{#/blank#} end. Steam burst from holes in the ground. Hard hills of rock became rivers of  {#blank#}5{#/blank#}  (dirty). Soon the whole city lay in {#blank#}6{#/blank#}(ruin). Many people died or were {#blank#}7{#/blank#} (injure). Everything in the city was destroyed. People were {#blank#}8{#/blank#} (shock) at this and wondered how long the disaster would last. The army organized teams to dig out those {#blank#}9{#/blank#} were trapped and to bury the dead. Workers built shelters for {#blank#}10{#/blank#} (survive). Fresh water was taken to the city. Slowly the city began to breathe again.

    The British have been drinking tea for over 350 years. But in fact, the history of tea goes much {#blank#}1{#/blank#}(far) back.

    The story of tea begins in China. According to the legend, the Chinese emperor Shen Nung was sitting {#blank#}2{#/blank#}a tree while his servant boiled drinking water, when some leaves from the tree blew into the water. Shen Nung,{#blank#}3{#/blank#} expert in herbal medicine, decided to try the water his servant created. As a result, it tasted so good that later the drink was{#blank#}4{#/blank#} we now call tea.

    It is{#blank#}5{#/blank#}(possible) to know whether there is any truth in this story. {#blank#}6{#/blank#}, tea drinking certainly was established in China many centuries before it had even been heard of in the west. Containers of tea {#blank#}7{#/blank#}(find) in tombs dating from the Han dynasty (206BC-220AD) before tea was firmly established as the national drink of China in the Tang dynasty (618-906AD). It became {#blank#}8{#/blank#} a favorite thing that during the late eighth century, a writer {#blank#}9{#/blank#}(call) Lu Yu wrote the first book entirely about tea, the Ch'a Ching, or Tea Classic. It was shortly after this that tea was first introduced to Japan, by Japanese Buddhist monks who had travelled to China to study before. Tea drinking has become a vital part of Japanese culture,{#blank#}10{#/blank#}may be rooted in the sprit described in the Ch'a Ching.
