任务型专练(1)If your family is like many in the United States, unloading the weeks groceries includes hauling a case or two of bottled water into your home. On your way to a soccer game or activity, its easy to grab a cold one right out of the fridge, right? But all those plastic bottles use a lot of fossil fuels and pollute the environment. In fact, Americans buy more bottled water than any other nation in the world, adding 29 billion water bottles a year to the problem. In order to make all these bottles, manufacturers use 17 million barrels of crude oil. Thats enough oil to keep a million cars going for twelve months. Imagine a water bottle filled a quarter of the way up with oil. Thats about how much oil was needed to produce the bottle. So why dont more people drink water straight from the kitchen faucet? Some people drink bottled water because they think it is better for them than water out of the tap, but thats not true. In the United States, local governments make sure water from the faucet is safe. There is also growing concern that chemicals in the bottles themselves may leach into the water. People love the convenience of bottled water. But maybe if they realized the problems it causes, they would try drinking from a glass at home or carrying water in a refillable steel container instead of plastic. Plastic bottle recycling can helpinstead of going out with the trash, plastic bottles can be turned into items like carpeting or cozy fleece clothing. Unfortunately, for every six water bottles we use, only one makes it to the recycling bin. The rest are sent to landfills. Or, even worse, they end up as trash on the land and in rivers, lakes, and the ocean. Plastic bottles take many hundreds of years to disintegrate. Water is good for you, so keep drinking it. But think about how often you use water bottles, and see if you can make a change. And yes, you can make a difference. Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours.TitleDrinking Water: Bottled or From the Tap?(1) _ situationAmericans consume the (2) _ bottled water in the world.(3) _ for peoples preference for bottled waterBottled water is of higher (4) _ .Its more (5) _ for people to drink bottled water.Problems with bottled waterThe (6) _ _ of plastic bottles use lots of fossil fuels.Water bottles we use cause serious (7) _ _.(8) _ the passage offersUse bottles (9) _ of glass or steel.Use a refillable plastic bottle as many time as (10) _ before recycling.(2)Many people think a telephone is a necessity. But I think it is a pest (有害的事物) and a time waste. Very often you find it impossible to escape from it. If you have a telephone in your own house, you will admit that it tends to ring when you least want it to ring; when you are asleep, or in the middle of a meal or a conversation or when you are just going out, or when you are in your bath. Are you strong-minded enough to ignore it? You are not. You think there may be some important news or message for you. I can assure you that if a message is really important it will reach you sooner or later. Have you ever rushed crippling from the bath, or chewing from the table, or dazed from the bed, only to be told that you are a wrong number?But you will say, you need not have your name printed in the telephone directory, and you can have a telephone which is only usable for outgoing calls. Besides, you will say, isnt it important to have a telephone in case of sudden emergencyillness, accident, or fire? Of course, you are right, but here in a thickly populated country like England one is seldom far from a telephone in case of dreadful necessity.I think perhaps I had better try to justify (证明是有理的) myself by trying to prove that what I like is good. I admit that in different circumstancesif I were a wealthy and powerful businessperson, for instance, or badly ill and had to lie in bed, I might find a telephone a necessity. But then if I were a taxi-driver I should find a car as necessity. Let me put it another way: there are two things for which the English seem to show particular talent: one is mechanical invention, the other literature. My own business happens to be with the use of words but I see I must now stop using them, for I have had just been handed a slip of paper to say that somebody is waiting to speak to me on the telephone. I think I had better answer it. After all, one never knows, it may be something important.Title: The (1) _Different (7) _ about itMany peopleIt is (2) _ when one wants to make a call, especially in time of (3) _ .The authorIt can (4) _ time and even be (5) _ .Not everyone, (6) _ a businessperson or a sick person who has to stay in bed, needs it.I dont need it because my job is writing.(8) _ with itIt always seems to ring when one is doing something else or doesnt want it to ring.Almost (9) _ can ignore it even if they want to.One (10) _ to answer it only to find that he is misdialed.(3)Blood donation, also called blood banking, is a wonderful thing to do.

Apart from a campaign, “saving physical stores”, many Chinese politicians and scholars have also urged the government to adopt measures to prevent bookstores from closing down their businesses, because unlike shops selling other goods, physical bookstores play the important social role of passing down knowledge and culture to younger generations. Besides tax cut, the government should also take other measures to support and encourage the development of such bookstores. Online bookshops are popular because they offer customers easier access to books, more attractive prices, and delivery service. Readers can buy almost any book sitting at home. Physical bookstores have actually become “the exhibition halls” of online bookstores. People read and select books in physical bookstores, and then buy them from online bookstores. However, physical bookstores have their own advantages. The physical bookstores make people feel the existence of culture. Entering a bookstore is like absorbing various elements of culture. For example, they offer the choice of feeling a real book rather than just the chance to see the cover and read a few introductory lines. But they can also offer lower prices, sales promotions and better service, and organize readers club and other activities to attract more booklovers. A citywide delivery service could make it more convenient for readers to buy books from them. Moreover, the physical bookstores can make use of new technologies to improve their services, develop their online sales and expand their business.ThemeHow to (1)_ physical bookstoresIntroductionThe popularity of online bookstores is a (2) _
