to make marriage vows (誓言) mean what they say.I am a good friend to my friends，and they to me.Without them，there would be nothing to say to you today.So here’s what I want to tell you today：Get a life.A real life，not a desire of the next promotion (提升)，the bigger paycheck，the larger house.Get a life in which you are not alone.Find people you love，and who love you.And remember that love is not

that can be worn while they wash.The suit has been specially designed so that it can be cleaned under the showerhead.There is no need for soaking (浸泡)，dry cleaning—or even soap.The Japanese market has taken a liking to the “shower suit”，described as “revolutionary” by its owner Australian Wool Innovation (AWI)，which is the research and marketing body that represents Australian woolgrowers.Orders have been placed for 170,000 of the woolen suits.The suit could be worn in the shower，although it was probably better to hang it on a clothes hanger and carry it instead，AWI corporate affairs spokesman Stephen Feighan said.“The idea is that you hang it up and then...yougive it a spray (喷雾)，and it’s dry the next morning，” Mr Feighan said.A Japanese researcher working for AWI invented the suit by combining three technologies.The secret is the best lining (内衬)，which allows the suit to dry quickly.The shower suit attracted busy corporate people，particularly those who often traveled or stayed up late，Mr Feighan said.The airline industry was also interested.Mr Feighan confessed he had not worn one of the suits yet，or tried to wash it in the shower，because they cut to fit Japanese figures.AWI believes that the shower suit will spread from the Japanese market through Europe and India.Mr Feighan hoped the suit，made from local wool，would be available in Australia in 12 to 18 months’ time.5．What is the writing purpose of the article?A．To introduce a newly-designed shower suit.B．To help the white collars arrange their life more sensibly.C．To provide suggestions on saving time in bath.D．To praise AWI for its important achievement.6．Which is true about the suit according to the passage?A．It can spare the owner’s trouble of soaking，dry cleaning and applying soap.B．It is of the quality of fast dry for its best cloth.C．It is not suitable for hanging.D．It has attracted more orders than any other suit.7．The suit draws the attention from all the following groups EXCEPT________.A．corporate people who are always on the goB．people on occasional business tripsC．the airline industryD．people burning the midnight oil8．Which of the following has much to do with Mr Feighan?A．The invention of the suit.B．The try-on of the suit.C．The combination of the three technologies on the suit.D．The popularization of the suit and best wishes for it9．It can be inferred from the passage that________.A．Australians prefer foreign markets to the domestic oneB．wool is the most favorite material for clothingC．westerners have different body sizes and figures from easternersD．Australia’s economy will not recover within a year答案Ⅰ.单项填空1．C考查冠词。

Unit 4 Global warming教学目标1) Learn some knowledge about the greenhouse effect and global warming.2) Know the contents of the text well by talking about this topic and reading.3) Discuss the problem of global warming and express your own opinions学情分析There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable(suitable for people to live in). Without it, scientists estimate that the average temperature on Earth would be colder by about 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain(维持) our current ecosystem. In other words，the normal greenhouse effect is a natural process which is to some degree beneficial to us.重点难点Master the main idea of the first five paragraphs by talking about the topic.教学过程活动1 【讲授】Unit 4Teaching procedures:Step I. GreetingsGreet the whole class as usual.Step II. Lead-inLead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.Step III. Analyze two graphs to learn the main idea of the first five paragraphs.From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit. All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.More such burning means more carbon dioxide added to the atmosphere.We can see clearly that the levels of carbon dioxide have increased greatly over the past decades.Higher levels of carbon dioxide means sharper increase of the temperature. The phenomenon is called global warming.There has been a debate towards global warming over the pastyears. Opinions about it vary from person to person.Step IV. Read the whole passage to review the main idea of the first five paragraphs and know the two different opinions. Dr. FosterCarbon dioxide has caused the global temperature to ________. An increase of five degrees would be a ____________ and could be very ________.Possible results: __________________(海平面上升)___________________(洪灾)___________________(恶劣的风暴)___________________(干旱)__________________(饥荒)__________________(疾病的传播)___________________________(物种的消失)George Hambley:Any warming will be ______ with few bad ______________________. More carbon dioxide is a _________ thing, which makes crops __________ more and will encourage _____________________.Step V. Discuss the statement: We should take immediate action about global warming.Requirement: Write down your reasons and possible measures on your learning sheetStep VI. Presentation.Ask some students to read their reasons and possible reasons loudly to the whole class.Step VII. Assignment.Make up a complete composition in groups. The passage should include your point of view, your reasons and your measures.精美句子1、善思则能“从无字句处读书”。
