【正文】 Selecting is very important for your grades in America. So at the first term, don’t select too many courses, or you’ll feel very nervous and it may influence your study. Then you have to ask for some teaching plans. There is some information about subjects, time arranging, marks and textbooks. At the same time, you must choose the teachers. Different teachers have different teaching methods. If the teacher is called “killer” by the last grade, many students will give up choosing him. Because this kind of teacher will leave too much homework, too many exams and give too low grades.There is another thing after you select the courses and the teachers. How to buy textbooks makes each student feel hard. The textbooks in America are very expensive. Each copy is about $30～50. In order to save money, many students buy some used textbooks, and some students usually borrow textbooks from the school library. You must get enough ready before classes. In class, discussing is very important. The teacher encourages you to raise questions or show your own opinions. They don’t usually ask you to sit well. Instead they allow you to sit or stand everywhere you like. They don’t give you much homework to do. You can learn some knowledge and do exercises by yourself. 64.

It is the fifth generation of the iPhone, succeeding the iPhone 4, and was announced on October 4, 2011. Siri on iPhone 4S is like a person assistant. It lets you use your voice to do things on the iPhone. You can just talk to Siri as you talk to a person. Siri understands what you say, knows what you mean, and even talks back. Say something like “Tell my wife I’m running late.” “Remind me to call the doctor.”“Any fast food restaurants around here?” Siri does what you say, finds the information you need, then answers you. It’s like you’re having a conversation with your assistant. Siri not only understands what you say, but it’s also smart enough to know what you mean. So when you ask, “Any fast food restaurants around here?” Siri will reply, “I found a number of restaurants near you.” Then you can say, “Hmm. How about French fries?” Siri remembers that you just asked about restaurants for something to eat, so it will look for KFC restaurants in the neighborhood. And Siri is active, so it will question you until it finds what you’re looking for. When you want to do something, just ask Siri to help you do it. Siri uses almost all the builtin apps on iPhone 4S. It writes texts and sends messages. It searches the web for anything you need to know. It plays the songs you want to hear. It gives you directions and shows you around. It makes calls, plans meetings, helps you remember and wakes you up. In fact, ask Siri what it can do — it even speaks for itself. Siri is easy to use and does so much. You’ll keep finding more and more ways to use it.64. When was iPhone 4S announced? 65. What is Siri on iPhone 4S like?66. How can you use Siri to do things on the iPhone?67.

Do you often sleep after playing games on your phone? Mobile phones are a great way to beat boredom and get in touch with friends. But they are also great places for bacteria (細(xì)菌) to live.A US study showed that there are as many bacteria on your mobile phone as on your toilet seat. The study said about 2700—4200 units of bacteria were found on each phone scientists tested. In drinking water, the limit is less than one unit per half cup.In fact, mobile phones are not the only dirty things around you. There are many things that carry a lot of bacteria you may not pay any attention.Toothbrushes can be dirty, especially when you put them close to the toilet. Studies show that every time you flush（抽水沖洗）the toilet, bacteria can remain in the air for at least two hours. These bacteria may pollute your toothbrush. It is better to put your toothbrush far from the toilet and make it in upright position after each use. It is also important to change your toothbrush every three months.Everyone love money, but no one loves the bacteria on it. From the supermarket to someone’s home, a large number of bacteria live on every note. US scientists found anywhere from 126,000 to 135,000 bacteria on a single bill. The way to deal with this problem is to try to wash your hands as often as possible. Funnily enough, the very sponge that makes your dishes clean is really the dirtiest of them all. Sponges stay wet long after being used, which makes them more likely to carry bacteria. Wash the sponge carefully after each use. Microwave the sponge for 60 seconds. The high heat can kill most bacteria.64. What is the limit in drinking water?65. Where should you put your toothbrush?66. What should you do after you touch money?67. How can you kill the bacteria on the sponge?68. What does the writer want to tell us in the passage?Usually people don’t realize the importance of knowing some knowledge about fire fighting until fires happen / a fire happens. 2011——2012學(xué)年度門頭溝區(qū)初三第一次綜合練習(xí)For many of us, the idea of a family is a lot narrower(變窄了) than it used to be. Today children go away to college, and take up jobs wherever chances seem greatest. So instead of growing up in a family with grandparents, aunts, uncles and cousins, many of us are t
