We’re surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty 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 known 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(醋), because it can produce poisonous gas.Without chemistry, we wouldn’t have fireworks displays on important days.
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 food. Baking is a great example of chemistry. Too much or too little of any ingredient(成分,尤指烹饪) 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 meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest-looking things.

第二节读写任务(共1小题,满分25分)
李华是一名高一年级的中学生,阅读她的这篇日记,然后按照要求写一篇150词左右的英语短文。
August 6, 2010                           Sunny
Half of my summer vocation has passed. It's supposed to be the time for me, a senior- one student, to relax, read novels, chat with friends and, anyway, not to worry about getting up at 7 am for class.
Even before the vocation, I had been arranged to attend different "enrichment" classes to improve my main subjects. My mum did ask for my opinion whether I would like to go to such classes. But could I refuse? My negative reply would cause a long persuasion, which I would not face.
Besides, the teachers made summer homework lists as we were sent off for vocation. The reason sounds persuasive -- to keep us studying during the long break so we wouldn't forget our lessons.
I found that the joy of my summer vocation had been stolen. But do I blame my mum or my teachers? Of course not. Though I don't like listening to my mum's lessons about society competition, I still understand that I should do well in study. What bothers me is that I don't feel like sitting in the classroom focusing my mind on the teachers' lectures. My mind is staying outdoors, tasting the freedom of the blue skies, the power of sunshine and the comfort of gentle wind....... not only scores or certificates.

At about 4 am, after hours of being unable to sleep, of shivering in the cold mountain air and trying to silence my crying kids who kept waking up, of attempting to find a comfortable sleeping position, of listening to whether there might have been a bear outside our tent, I finally couldn’t stand it any more. I complained, “Everything has gone wrong.”

My wife and I were in one tent with our two young kids. A hundred yards east away was Summit Lake, where the glorious early morning mist was shimmering(闪烁)off the water. A couple miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet above sea level, and huge snow dotted the scenery even in mid August. Further west still was Bumpass Hell, with steam rising up.

As the sun crept up over the edge of the Lassen peak, we fired up the camp stove and had breakfast. Half an hour later, my six-year-old daughter and I were in the parking lot of the Lassen peak trail, getting ready to go up the mountainside. We wouldn’t make it all the way, but it didn’t matter. We would see nature at its extremes: the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it; the blues of the sky shading into the blues of distant lakes, which in turn shaded into the whites and grays of the snow.

My daughter grabbed my camera. She wanted to take a photo of “the composite(混合物)”of colors. Looking out over that scenery, and seeing my daughter fascinated by nature, I felt stupid about my morning complaints.

Yes, camping is uncomfortable. And yes, there’s a lot to be said for getting out a credit card,reserving a room in a nice hotel, and going out for a fancy meal. But there’s also something wonderful about being so close to raw nature. And , as important, there’s something vital about getting young children out of their increasingly modern comfort zones and forcing them to meet the world around them.
