All the friends inv ited were a little 36 . It’s not that Ben is unsociable , or a bad cook , but it’s just that he never 37 more than he has to. So how come he was inviting us round for a meal? Hadhe bought something 38 for his friends? He greeted us at the door and showed us into his dinning room where a 39 table was waiting for us.“Nothing but the 40 for my friends!”said Ben. We all sat down and looked 41 at each other—what did he 42 to?Ben returned with four bowls of hot soup.“It’s a 43 of carrots , potatoes and tomatoes,”said Ben. The next 44 was also a little strange in that we didn’t quite know what it was again. It’s just 45 mixture of vegetable.As we ate we chatted and finally the 46 turned back to what we were eating.“Was there a recipe（食谱）for this,” asked Marina ,“or did you 47 it up?”Ben put his fork down. “What I cooked 48 what I could find.”Marina was surprised.“But you can find anything in supermarkets these days.”“But there’s 49 choice in what you can find 50 supermarkets.” He replies.51 that we had all finished the food , Ben decided to tell the truth. He had read recently that supermarkets usually 52 away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of 53 , boxes of throw-away vegetables and fruit.So Ben had 54 provided a decent(不错的) meal for his friends , and made us away of the fact that there are many poor people who need the food , but the amount of food thrown away is enough to 55 millions of people.36.

Unit 4 Global warmingⅠ.阅读理解AWildfires and heat waves have been troubling the states of California and Arizona this year. Since 2010, about 6.4 million acres have been burned on average per year. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence of these natural disasters is likely to increase.As temperatures increase, wildfires become more common. As this cycle progresses, climate change and wildfires both increase frequently and seriously. Forest fires are also developing at higher frequencies as a result of global warming. Firefighters use techniques like back-burning to help prevent further spread of these fires, but these measures are not always effective.Some factors that promote wildfires, such as drought and insect outbreaks, have been linked to global warming as well. Insects that kill trees and other plants make the remains more sensitive to fires, as the plant matter dries out and can more easily be burned. Higher temperatures that result from climate change cause more water to evaporate(蒸发)from reservoirs and lakes, which can lead to drought.With global warming causing higher temperatures, the wildfire seasons of affected areas lengthen. This occurs because summer heat begins to build earlier in the year, and the cooling fall season is delayed. For forests in the southwest United States, the conclusion of snow’s melting indicates the time when fires are able to start. Climate change has caused the melting of snow to occur earlier than it did 50 years ago by about one to four weeks.The global warming trend has hit Southern California extremely hard, and the months of January through April have been hotter this year than they have been for any others in recorded history. This has also caused a drought which has been severe or worse for the entire state. Last year, drought affected only 46 percent of California.With the results from these recent studies, global warming has been linked to an environment that promotes wildf ires, by creating higher temperatures and causing drought. California’s wildfire season is just starting, and the damages are likely to be worse as the season continues.1. What does the author intend to tell in the passage?A.Global warming causes high temperatures and wildfires.B.Forest fires have been bringing serious threat to the earth.C.High temperatures make water disappear at a high speed.D.California and Arizona are faced with the extreme weather.2. Why are insects connected with wildfire?A.Because tons of insects exist in the forests.B.Because drought drives insets into the forests.C.Because insects leave the trees dead and dry.D.Because the bodies of insects can burn easily.3. We can conclude from the passage that.A.it is impossible to prevent wildfire from happeningB.the southern states in the USA will see the longest summerC.it is necessary to raise awareness of fire preventionD.California has done nothing to fight wildfiresBFred and Bonnie have 21 children. First they had two of their own and they adopted 19 others from countries around the world. They adopted children from many countries, like Japan, India and Vietnam. Each time they made sure they had music, food, pictures, and books of the child's native country so the children would feel good about themselves.Fred and Bonnie had pre-school children running around the house for 26 years without a break! The washer was always going and clothes hung from one end of the room to the other. Everyone helped out with the housework. The family drank ten litres of milk a day.The couple enjoyed their children. They took care of small problems right away so they wouldn'tbecome big problems. Fred says, "If you have trouble with one of your children, don't worry. Worry doesn't help, and in time your child will be all right."When the children were older, Bonnie began travelling to India. She opened three homes for 170 homeless children. She travels there four times a year to bring food, medicine, and used clothing to the needy children.Back home, Bonnie cooks meals for her seven children still living there. The other children keep in touch. When Tran got married,18 brothers and sisters danced at his wedding.They hope their children will find their own way to help others. They want them to be happy, healthy and independent.Fred says, "Let me light my lamp and never wonder if it will take away the darkness."4. What does the word "adopted" underlined in Paragraph 1 mean ?A.raised children with government support.B.looked after children for parents who were busy.C.provided education for children from poor families.D.brought up someone else's child as his parents.5. What did the couple do to make sure that the children felt good about themselves?A.To offer them things from their own country.B.To feed them well.C.To make sure they could play well.D.To handle small problem right away.6. What does Bonnie do after the children grow up?A.She goes abroad to help more children in need.B.She still stays at home to cook for them.C.She set up three homes in Vietnam.D.She often visits her son in India.7. Why do the couple want to live such a life?A.To get extra money from the government.B.To be allowed to build more rooms.C.To have more chances to travel abroad.D.To offer help and to show their love.8. Which of the following is the best title for the article?A.Worry doesn't help.B.A big happy family.C.How to help others.D.Family should keep in touch.Ⅱ.完形填空The back door of the ambulance(救护车)was suddenly shut and the driver ran to the front, jumped into his seat, and started the engine.

They are used to visit the city. Red tourist buses have open4 (roof), which let people take photos, have an amazing view of the city and enjoy5 (them) as they drive past Big Ben, the Thames and so on.But how did the bus become unique to London culture?

Bus companies used different colors at the time. One of the7 (big) companies chose red because the bright colour made8 easy for the citizens to pick out the bus. In 1933, when London transport was grouped into a single company, they chose the most9 (wide)used color at the time-red.And so the color red stayed in London. But it was in the mid-1950s 10 the red double-floor was born. Its name is the Routemaster. Built between 1954 and 1968, they still look traditional.

I also liked Oxford, in which I saw much more old buildings. The Lake District was beautiful, but it was pity that it rained heavily when they were there. The most excited thing for me in the Britain was that I made a lot of friends there.Ⅴ. 书面表达假设你是李华，正在一所美国学校学习英文。

Unit 4 Section ⅢⅠ.阅读理解Global warming can lead to rising sea levels, extreme weather events and changes in precipitation (降雨量)．Global warming can also affect agriculture and glacier melt and can facilitate (促进) the spread of disease and the extinctions of species.So, it is necessary to prevent global warming.But how to do it?Many countries have been working to reduce greenhouse gas emission (排放) to prevent global warming.Driving an energy­efficient car can help to prevent global warming because hybrid cars can run on gas and electricity.The average hybrid can save 16,000 pounds of carbon dioxide a year! Also, do not use hot water if we do not need to, like when doing laundry.And take care with our appliances.Unplug them when we do not use them.In order to prevent global warming, we should get energy­saving light bulbs.And we can help to prevent global warming if we buy recycled products, also try donating or selling instead of throwing away.Besides, we can try buying products with less packaging.Buying in bulk can mean less packaging and less money being spent.What is more, we can plant trees.Not only do they suck up carbon dioxide, but also they provide cleaner air and save 2,000 pounds of CO2 a year.Students showed that man­made influences are adding to cycle considerably.So, how to prevent global warming? Many ways are also being pushed upon society.Turn the lights off, turn the TV off, walk to the shop, and buy a green car.But can all these little things actually add up to make a difference? Or do we need to put pressure on the corporations.This is where the real emissions are coming from.Yes of course we need to do all the little things ourselves.Once again, how to prevent it?
