阅读理解

    Do you think laughter can help you deal with pain? Scientists from Britain did two experiments(实验). The first was done in a lab. People wore special wristbands(腕带). Some of them were asked to watch comedies while others watched serious programs. Then the scientists tightened(勒紧)the wristbands to see how much pain the people could feel.

    The other test was done at an art festival. Some people watched a comedy show and others watched a drama(戏剧). At the same time, they had to put their backs against the wall and keep their legs bent(弯曲的)just like sitting on a chair. They did this before and after the show.

Scientists found that just 15 minutes of laughter improves people's ability to stand pain by 10%. However, the serious programs and the drama didn't make a difference to pain at all.

    The study found that the magic power of laughter comes from endorphins(内啡肽). These are chemicals(化学物质). They are produced by the human body. They make you feel less pain and can make people feel happier. Exercise can produce endorphins. Your muscles(肌肉)move in and out when you are laughing. Scientists believe that this makes your muscles tiring, so we start to produce endorphins.

    Scientists also found that the only real and relaxing laughter works not just polite laughter.

    Next time you have a headache, get together with a group of Mends, watch a funny movie and laugh. You will soon feel a lot better because laughter is the best medicine.

举一反三
Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.
But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.
Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt(高峰)during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later —-between 7 and 13 for girls and 9 and 15 for boys.
You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.

    Most people are changing their shopping {#blank#}2{#/blank#} (habit). On the one hand, people may want to buy the secondhand clothes to wear in special situations because they only wear them once or twice. On the o{#blank#}3{#/blank#} hand, there are some companies (公司) for renting (租) clothes and renting clothes is cheaper than b{#blank#}4{#/blank#} them. So people are able to s{#blank#}5{#/blank#} money and protect the environment.

①It is widely known that China has the best high-speed railway network (网络) in the world. Now, the country is breaking its own speed(速度) record with CR450. 

②CR450 can travel at 400 kilometers per hour on average, with a top speed hitting 453km/h. Before this, the fastest high-speed train operating in a rail network in the world is China's CR400, which runs at 350 km/h on average. Once put into use, for example, the CR450 will shorten the travel time from Beijing to Shanghai to just about two and a half hours, which takes at least four and a half hours at the moment. 

③"The key is not to make the train run fast but to have it brake (刹车) accurately (精准地) and steadily (平稳地), " Zhao Hongwei of the China Academy of Railway Sciences told CCTV News. The standard is that the CR450 should have the same brake distance as the CR400, which is 6, 500 meters, even though it travels a lot faster. It can also start braking more quickly, taking just 1. 7 seconds compared to the 2. 3 seconds needed for the CR400. 

④The engineers did lots of tests with the brakes to make the system better. In the tests, the brake disc (制动盘) got really hot, reaching temperatures of up to 700℃. Its color changed from black to red. The changes were then recorded. All the data were saved in a smart system to make a digital model of the brake system for calculations (计算). 

⑤Besides having a better braking system, the CR450 has the same noise level as the CR400. Moreover, it is 12 percent lighter and 20 percent less energy-consuming (耗能的), according to CCTV News. With all its advantages, people are getting excited about the train's debut (首次亮相), which is planned to be within this year.
