When my family moved to America from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect (尊敬) elders(长辈). Unluckily, this rule led to my very first embarrassment in the United States.
I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple（夫妻）, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect older people. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long talk about how sensitive(敏感) Americans are and how they dislike the description “old”. I then walked back to the table and said “sorry” to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.
In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.
However, in the United States, people think “growing old” is a problem because “old” shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect older people, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.
After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.

①Chemistry is everywhere in our daily life.Sometimes it's easy to see.At other times，it can be very hard to see the everyday chemistry at work，but nearly everything you touch has some chemicals（化学物质） in it.
②Chemistry helps to make products for use.Something as simple as toothpaste has at least three chemicals that keep your teeth clean.Other things in your daily life are created by chemistry，such as hair products and soap.Without chemistry，we would never have known that we need soap to get the oil out of clothes.
③Chemistry also helps us understand the world around us.Thanks to chemistry，we know bleach （漂白剂） can't be mixed with vinegar （醋），because the mixture can produce harmful gas.
④Chemistry plays a big role in food preparation.Cooking food causes it to go through a chemical change.That is why cooked food often tastes different from uncooked food.Too much or too little of any chemical material makes a difference to the result of baking （烘焙）.For example，the cake can be too soft or too hard.

Triathlon is a race in which each person swims, rides a bicycle and runs over very long distances. It has been held ten times in Hope Town. Sam, aged 20, finished nine races with his younger brother Luke. Every race was a victory for them. Luke can’t walk, talk or feed himself because of a rare brain illness since birth. But Sam wants his brother to know what it feels like to be part of a sport instead of having to sit and watch. A local TV journalist interviewed Sam after he received the Town Hero Award.
(J=Journalist, S=Sam)
J: How did you get the idea to include Luke in these events?
S: When I was ten, my mom showed me a video of two young men from another city doing triathlons. One of the men had a condition like Luke has. I got the idea from that.
J: What’s it like having Luke along?
S: I feel good and proud during the whole triathlon, for I’m giving something to Luke. He can experience things any other man would.
J: What do you get from him?
S: It’s the smile on Luke’s face. That smile brightens me. The feeling of knowing that I’ve done something for him is unbelievable.
J: When you received the Town Hero Award, you talked about the importance of changing the way you see things. What did you mean?
S: People see Luke very differently: “Oh, he can’t do something like that. He’s disabled.” But if you just change how you see things, you can see there are many possibilities where Luke can do swimming, biking or even triathlons, like we do.

For years，people thought that sleep was unimportant and inactive．Today，we know that sleep is important for good physical and mental （精神的），the brain is very active．
①By doing this they have learned that there are five stages of sleep．Stage one sleep is very light．During this time，a person wakes up easily．As we move into stage （A） ，our eyes stop moving and our brain waves move more slowly．During stages three and four （often called "deep sleep" ），it is very hard to wake up a person．During this time，the body repairs itself and makes more cells （细胞），the body makes a chemical used for growing．In the next stage—REM sleep—we begin to breathe faster and our eyes move around quickly，but （B）我们的身体不动。During this stage，we dream．
The amount of sleep each person needs is different，and is often connected to age． ②（C） In general，babies need fifteen to sixteen hours of sleep a day．Children and teenagers need nine to ten hours，while adults need six to eight．Over time，not having enough sleep—especially deep and REM sleep—can cause one to become sick more easily．Doctors also think that REM sleep is very important for learning，and memory． ③
