选项中有两项为多余选项。

Little-known facts about germsGerms are everywhere and in so many forms.__1__ There are some steps you can take to help prevent the spread of germs in your personal space.Computer keyboards can have more germs than a public toilet.Keys and spaces on a keyboard are main breeding grounds for bacterial and viral growth.__2__ Clean your keyboard regularly with specialized wipes for electronics, and remove dust with an air duster.__3__While it seems to make sense that covering your toothbrush would protect, the opposite is the case.With a cover on your brush, a more humid environment is created and more likely to encourage growth of germs.Wash your toothbrush when done, and allow it to air dry.Make sure you store it away from the toilet.Hand sanitizer(洗手液) does not always replace soap and water washing.Hand sanitizer is great when you’re not near a sink, and need to clean your hands.But given the choice of a spritz of sanitizer or good old soap and water, choose the soap and water route.__4__ Lather up and scrub hard for at least 20 seconds, and wash between your fingers and the back of your hands.Don’t skimp with the hand sanitizer either—cover the same hand areas as for soap and water.__5__ If you freeze foods that you suspect might be spoiled, freezing them will not kill the germs already in the food.Freezing prevents further bacterial growth, but when you thaw it out, the bacteria continue to increase and pollute your food.A．Freezing food does not kill germs.B．Try not to eat outside especially in summer.C．Exposure to germs can lead to many illnesses.D．Toothbrush covers do not protect your brush from bacteria. E．There are a lot of effective ways to get rid of germs in your house. F．Soap and water are only a better germ fighter when done properly. G．Some reports show five times more germs on a keyboard than on a public toilet.答案 1.C [本文第一段为主题段，说明细菌无处不在，形式多样，可以产生许多疾病，以下几段是说明一些知之甚少的关于细菌的实事以及应该采取的不受细菌伤害的方法。

The General Idea of This Period：This period aims at training students’ two skills—understanding general idea and getting detailed information by getting familiar with tones and intonation in spoken English and writing an well-organized letter about how to solve a specific problem.Students can improve these skills by listening，writing and finishing the relative exercises.Also in this period students can meet the theme of this unit again.Teaching Aims：1.Make sure the students know the usage of tones and intonation in spoken English and grasp the methods of getting the general idea and detailed information.2.Help the Ss learn how to organize a letter to save the endangered animal dodo.Teaching Important Points：1.Make sure the students know the importance of tones in spoken English.2.Enable the students to organize a letter in the proper and efficient way.Teaching Difficult Point：How to write a letter in the correct way.Teaching Methods：1.Listening-and-answer activity to make the students know the importance of tones in spoken English.2.Practice to improve the students’ writing ability.Teaching Aid：A tape recorder and a projector.Teaching Procedures：Step 1 RevisionT：Good morning，boys and girls!Last class I asked you to prepare the description of dinosaurs and Milu deer and dodos，so now I will ask some of you to have a try.Any volunteers?S1：Dinosaurs lived on the earth long before humans came into being.There were many different species of them，of which a rare new one was able to run as well as climb.The reasons for their dying out are not sure.Maybe because of a large rock or due to the hot weather.S2：Dodos lived on the earth long long ago.They lived on an island called Mauritius.They were curious and kind hearted and quite different from most of the animals there.They were birds，but they were large and only had small wings.Their favorite activity was to wander along the beach and wait till the insects were ready to be eaten.S3：Milu deer used to be common in China.They lived together and lived on grass.But as a result of hunting，they disappeared from China later.Luckily，some were taken to Britain before that.So Chinese government can bring back some.Now there are more and more Milu deer in China.T：Everyone has done a very good job!Step 2 Brainstorming about tones in spoken English（Teacher asks two students to answer two easy questions，then express gratitude using different tones.One is ”Thank you↘”.The other is “Thank you↗.”）T：Well，just now I said “Thank you”，do you find some differences?Ss：You use different tones.T：Good.In the first one，the falling tone shows that I am very grateful.But in the second one，the rising tone means that is what the S should do and I was not really grateful.T：In spoken English，tones are used to express different feelings.To understand how the speaker is feeling，listen for four main things：the volume of the languagea rising or falling tonestress on certain wordspauses in the sentencesStep 3 Listening for general ideaT：OK，now we are going to listen to the story about another animal named dodo.Please have a look at the picture on P31.What does it look like?Ss：It looks like a duck.It’s very large.T：What about its wings?Are they very large too?Ss：No，its wings are very small.T：Can it fly high in the sky easily?S1：I don’t think it can easily fly high in the sky.T：Do you agree with her?Ss：Yes.T：So what might be its problem?S2：It can only walk on land.And when there is an animal attacking it，it can’t escape.T：You might be right.Let’s listen and see.As for the first time，you don’t have to understand every word.You can ignore what you don’t understand and concentrate on what you can understand.Now please open your books and turn to Page 30 to go through the Ex.2 and try to predict what might happen to dodo.（Two minutes later）T：What happened to dodo?Ss：It disappeared.T：Right.Check the answers to Ex.2 and get some Ss to tell the mistakes in the other choices.Step 4 Listen for detailed informationGet the Ss to listen to the tape again and fill in the blanks.Once upon a time I lived on the earth too.I was called “dodo”.My home was an ______ called Mauritius.I was ______ and ______ and quite ______from most of the animals there.I liked to make friends with the other animals and never ______.I have no enemies.We were birds too，but we were large and only had small ______.My favorite activity was to ______ along the beach and wait till the insects were ready to be eaten.Get the Ss to discuss the answers in pairs and then check the answers to blanks （Suggested answers：island，curious，kind-hearted，different，quarreled，wings，wander）and Ex.1 （CDBC）.Get them to tell the reasons for their choices.Step 5 Further PracticeT：After we learn the story about the dodo，we shall again know the importance of protecting our environment.In fact to protect our earth is to protect ourselves.Next we shall listen to one more story about human beings and their environment.Please turn to P62.Listen for the first time and get the general idea.（After listening for the first time）T：What is the main idea of the story，do you think?S1：It’s about how a farmer improved his empty land and made his farm more beautiful.T：Good job.Get the Ss to listen for the second time and try to finish Ex.1 on P62.（After the Ss’ listening for the second time）Get them to discuss the answers in groups of four and then check the answers together.At last listen to the tape for the last time to check the answers.Listen for the third time and finish Ex.1.Step 6 Summary and HomeworkT：In this class，we have learned the importance of tones in spoken English，how to find out the general idea and the detailed information.After class，you should go on listening to more materials and try all efforts to make your ears sharp.That’s all for this class.Class is over.Homework：Surf the internet to find more information about the endangered animals in China and think of some ways to protect them.Step 7 The Design of the Writing on the BlackboardUnit 4 Wildlife protectionPeriod 4Listen for the general ideaListen for detailed informationtones，intonation，stress
