We're surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher conducts a big experiment in class. At other times, it can be extremely hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.
Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have realized that we need soap to get the oil out of clothes or skin.
Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can't be mixed with vinegar, because it can produce poisonous gas. Without chemistry, we wouldn't have had fireworks displays on important days like the Spring Festival.
Chemistry 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 raw (生的) food. Baking is a great example of chemistry. Too much or too little of any ingredient makes a difference to the result of baking, for example, the dough (面团) won't rise or the cake will be flat.
Chemistry isn't something that just lives in a lab; it's something that you come across hundreds of times every day. If you know how chemistry works, you will get a greater comprehension of the science behind some of the simplestlooking things.

It was a hot, sticky (闷热的)summer day in Texas and I was surrounded by laundry, loads of baby clothes all over the floor.I folded a towel, tears streaming down my face.My newborn Dillon, just a few weeks old, was sleeping peacefully beside me.My 4yearold Tanner was watching “Ninja Turtles”,laughing at the TV screen.

In your life, sometimes you may be asked to speak in front of a large group of people. Although it sounds a little scary, even those with stage fright can speak successfully to the group with adequate preparation.
Practice your speech before the big day. 1. If possible, practice the speech in front of a friend or family member to get used to saying it to real people. If you feel you must have note cards, limit the amount to about three cards. This will force you to keep your speech concise and help you keep your eyes focused on your audience.
Remember why you’ve been invited to speak. If you’re battling fear over speaking to a large group of people, keep your mind on the fact that you were selected for this important role. The speech organizers must have seen something valuable in you or your expertise. 2.
Remember that fear of public speaking is very common. 3. Most of the people in the audience would be feeling the same fear and stress that you do in your position. Knowing this may make you feel better.
4. What you say should be tailored to why you’re there and who you’re speaking to in order to avoid sounding general. If speaking to a charity group, mention the good work certain specific individuals have done for the cause. If speaking at a business conference, briefly state why you want to help these people.
Keep eye contact with the crowd. 5. Pick one person in each section and look at him while you’re speaking. After each important point in your speech, switch your focus to another section. When you focus only on one person at a time, the size of the crowd isn’t as frightening.
A.A good memory is really helpful.
B. Show appreciation to your audience.
C. Mention your audience in your speech.
D. The more you have it memorized, the better.
E. In fact, it’s normal to feel nervous or stressed out before a big speech.
F. Separate the crowd into three sections mentally as you get up to speak.
G. The knowledge of other people’s respect for you should reduce some of the fear.

Sometimes life makes more sense when you look at it in reverse (相反). That's certainly been true for me.
Last Christmas, at 39, I caught a disease which attacked my knees and eyes. At its worst I could hardly walk or see. For months I' d have to crawl (爬) across the floor to use the bathroom or get a drink of water when my husband wasn't home. For a while I could only see shapes and colors so I couldn't drive.
My parents kept begging me to let them come out to stay with me in Los Angeles, but our apartment is small and I knew there was nothing they could really do to help me. For the excellent health insurance my husband had through his job, I was receiving the best medical care possible.
My only problem was that I couldn't drive to my doctors' appointments and I didn't want my husband to keep missing work to drive me. Three days after I explained this to my parents, a check came from them with a note saying this was "taxi money". Several months later another check showed up from my brother to help make up our income since I wasn't able to work. It probably goes without saying that I was extremely grateful to have family members who could and would support me during the hard time.
In terms of my day-to-day existence, I live in a village within Los Angeles called Brentwood so I was able to walk to the local post office, market, bank, and library. But once there, I had to depend on the kindness of strangers to help me. Los Angeles is a big city, but I lived in a village with a wonderful community (社区) of people who were kind and patient.
Slowly I became well. Life was good again and I thought I had a clear understanding of the blessings (恩惠) this illness has provided.
