Here's a message {#blank#}1{#/blank#} needs to be kept in mind by every mom and dad. You love your kids not because o {#blank#}2{#/blank#} they do, but because of who they are.

    In fact, raising a child is just like training a dog. You reward your children because of their {#blank#}3{#/blank#} (succeed) or progress they made.  {#blank#}4{#/blank#} (similar), a circus trainer gives a dog some food every time it  {#blank#}5{#/blank#} (jump) through a hoop(圈).

    The dog isn't loved for itself, {#blank#}6{#/blank#} for its actions.

    Dr. Laura Schlessinger, the popular talk show host, has a new book for children {#blank#}7{#/blank#} (title) “Why Do You Love Me?” Part of the story includes a mother {#blank#}8{#/blank#} (explain) to her son that it is not what he does that makes her love him—she loves him because he is unique and he is {#blank#}9{#/blank#} (she) son.

    Every mom, dad and grandparent needs to memorize the words of {#blank#}10{#/blank#} popular song: “I love you most of all because you're you.”

    There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community(医学界){#blank#}1{#/blank#}a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease—the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required{#blank#}3{#/blank#}(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if is missing something. As{#blank#}5{#/blank#}result, people will eat more food to try to make up for that something missing. Even{#blank#}6{#/blank#}(bad), the amount of fast food that people eat goes up. Fast food{#blank#}7{#/blank#}(be) full of fat and salt; by{#blank#}8{#/blank#}(eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be{#blank#}9{#/blank#}(care) not to go to extremes. Like anything, it is possible to have too much of both,{#blank#}10{#/blank#}is not good for the health.

    With the{#blank#}1{#/blank#} (develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because {#blank#}2{#/blank#}air pollution. Air pollution is caused by the following {#blank#}3{#/blank#}(reason): about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off {#blank#}4{#/blank#}(poison) gases. 25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health {#blank#}5{#/blank#}to others. {#blank#}6{#/blank#}these, about 10%of air pollution is caused by other reasons. We should take some measures to fight {#blank#}7{#/blank#}pollution. New fuel can be used to take {#blank#}8{#/blank#} place of gas. We can plant more trees. If everybody realizes the{#blank#}9{#/blank#}(important) of environment and does something to stop pollution, the problem will {#blank#}10{#/blank#}(solve).

    Generally speaking, joy {#blank#}1{#/blank#} (express) by laughter. But as it turns out, it reveals a lot more than the fact {#blank#}2{#/blank#} you are happy. It enables listeners, even those who cannot observe you, {#blank#}3{#/blank#} (realize) if you are having a good time with a close friend or laughing {#blank#}4{#/blank#} (polite) with a complete stranger.

    At least, this is the conclusion {#blank#}5{#/blank#} (reach) by a team of scientists led by Greg Bryant, {#blank#}6{#/blank#} assistant professor of Communication Studies at the University of California, Los Angeles. The researchers began by {#blank#}7{#/blank#}(request) volunteers from across the world to send them audio clips(音频剪辑) of people laughing. The 48 tapes they received {#blank#}8{#/blank#} (range) from recent recordings of laughter between two college friends {#blank#}9{#/blank#} ones from conversations made ten years ago. The clips also had all possible {#blank#}10{#/blank#} (combine)--communications between friends, strangers, all-male groups, all-female groups, etc.

    Bryan says that the results of this cross-cultural examination show that people all over the world know laughter in similar ways.

    The Great Wall was grand, a little rainy at first, but grand all the same. The mist covered the far ends of the wall,{#blank#}1{#/blank#}(give)it an almost mysterious feeling. The fog rolled in and out of the high mountains, revealing new parts of the wall as {#blank#}2{#/blank#}(quick)as it covered them. I kept on walking, seeing watchtower after watchtower {#blank#}3{#/blank#}my way. To my {#blank#}4{#/blank#}(relieve), many people had decided today was not the best day {#blank#}5{#/blank#}(climb)the wall, and I was there with very few people. I walked for {#blank#}6{#/blank#}seemed like miles. Then I saw just how long the wall I was standing on stretched for.

    It was {#blank#}7{#/blank#}(end)! I walked and walked, but after every hill I climbed, there was another long stretch of wall. I eventually came to {#blank#}8{#/blank#} long staircase. Later I found out that it {#blank#}9{#/blank#}(call) “Chairman Mao's Challenge”.I accepted, and after climbing the hundred plus stairs to the peak, I had to admit that the Great Wall truly lives up to its reputation. So if I {#blank#}10{#/blank#}(have)another chance to travel to China, I would never hesitate to visit the Great Wall again.
