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 the reason 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．
⑤Chemistry isn′t something that just lives in a laboratory； it's something that you meet hundreds of times in life．Knowing how chemistry works will give you a greater understanding of the life．

A habit is any action that we have performed so often that it becomes something that we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to get rid of these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.
First, look at why you do it. In other words, what’s the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it? It may make you feel a little better for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get more time to spend on the Internet!
Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn.

Nowadays film cameras are going out of our life. Do you remember how it works? And do you know the difference between a film camera and a digital camera?
A film camera is a light-proof box, which all light can’t go through. It has a lens (镜头) system to focus light onto the film at the back of the camera.
Let’s suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. Light goes into the camera lens and hits the shutter (快门). In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to take a picture. When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed (反向的) picture on the film. When you finish the roll (卷) of the film, you can take it to the photo shop to develop it and you will have a great picture!
Film cameras and digital cameras work in a similar way. In digital cameras, the light falls not on film but onto a sensor (传感器) called a CCD. This change light and color into a digital information or pixels (象素). The CCD is the heart of any digital camera and usually the most expensive part - depending on how good it is.The underlined word “light-proof” in the passage means “_____”.
| A．不透明的 | B．不透风的 |

| B．A lens system |
| C．A light-proof system |
| D．A system |
