Steven Stein likes to follow garbage trucks． His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter，including things that fall off garbage trucks as they drive down the road． What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bag．
Americans use more than 100 billion thin film plastic bags every year． So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts （收银台）． The bags are prohibited in some 90 cities in California， including Los Angeles． Eyeing these headwinds， plastic﹣bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume．
Among the bag makers' arguments： many cities with bans still allow shoppers to purchase paper bags， which are easily recycled but require more energy to produce and transport． And while plastic bags may be ugly to look at， they represent a small percentage of all garbage on the ground today．
The industry has also taken aim at the product that has appeared as its replacement： reusable shopping bags． The stronger a reusable bag is， the longer its life and the more plastic﹣bag use it cancels out． However， longer﹣lasting reusable bags often require more energy to make． One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic．
Environmentalists don't dispute（质疑） these points． They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years．

If you've been joining in chat room conversations, or trading e-mail with Web pals, you have become one of the millions who write in a peculiarly short form of English.
And you've got a sense of humor about short forms like SOHF(="sense" of humor failure) to describe Internet newcomers who don't understand you.
Across the globe, every night teenagers and their elders are “talking” online—many of them are talking at the same time.
It's fast: try talking to six people at once. It's brief: three or four words per exchange. It takes wit, concentration, and quick fingers.
And it requires tremendous linguistic economy. There's neither time nor space for explanations. Why consume precious key-strokes telling six friends you have to leave for a moment to take care of your little brother when BRB(="be" right back) will do? Want to enter a conversation? Just type PMFJI(="pardon" me for jumping in). Interested in whom you're talking to? Type A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a response from your pal.
If something makes you laugh, say you're OTF(="on" the floor),or LOL(="laughing" out loud),or combine the two into ROTFL(="rolling" on the floor laughing).
And when it's time to get back to work or go to bed, you type GTG(="got" to go) or TTYL(talk to you later).
People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing emotion, as it takes more time to hold down the “shift” key and capitals. Punctuation is going, too. In order to talk to several people at the same time on the Internet_______.
| A．you have to speak fast and fluently |
| B．you have to express your ideas in a brief way |
| C．you should speak with wit and humor |
| D．one should pay much attention to the accuracy of the words |
If you get 17/F/NY as an answer to your A/S/L, it means_______.
| A．the person on the other end is 17 from New York and he is fine |
| B．you are talking to a girl who is 17 and lives in New York |
| C．you are talking to 17 girls who are from New York |
| D．the person who are talking to you is a 1.7-foot tall New York girl |
To save time on the Internet_______.
| A．some people leave their letters in the dustbin |
| B．some people never use “shift” in their writing |
| C．many people leave the capital and punctuation |
| D．people seldom use capital letters or punctuation |
Methods of training animals have changed greatly in recent years. Zoo keepers have always had problems getting the animals to leave their cages in order for the cages to be cleaned, and also training them to move indoors when appropriate. Another problem was that many of the large animals became listless and bored. In the last twenty years, scientists have done research on dolphins and whales, training them to obey commands. The scientists found they could get animals to obey by rewarding them with food and affection when they responded correctly.
Proper training allows the animals to receive the care they need. It was very difficult to get untrained animals, especially the larger ones, to stay still when they needed medical attention. Now they can be trained, on command, to remain still and even to allow blood samples to be taken and shots administered. All this is accomplished through positive reinforcement, without the use of any force. Affection training, as this process is called, has been used with great success on a wide variety of zoo animals. Animal behavior experts have taught zoo keepers to train bears, tigers, monkeys, and many other species to behave in a way that provides for better animal-keeper interaction. This training also keeps the animals from becoming bored and inactive.
Although some people proclaim(谴责) that this training is inhumance and cruel to animals, results have shown that captive(猎获的)animals who previously were not doing well flourish under the new training procedures.The word “listless” means _______.
| A．countless | B．obedient |
| C．inactive | D．mysterious |
Which of the following is valid conclusion based on this passage?
| A．It is safe to pet any animal. |
| B．Many animals respond favorably to rewards and affection. |
| C．Animals in the wild can be trained. |
| D．Animals should not be kept in zoos. |
The writer's purpose is to _______.
| A．persuade people not to feed animals in the zoo |
| B．show how easy it is to train animals |
| C．explain method of training animals through rewards |
| D．criticize zoo keepers |
Which of the following is an opinion?
| A．Zoo keepers had problems in getting animals to leave their cages. |
| B．Training is cruel to animals. |
| C．Animals obey commands if they are trained to do so. |
| D．Many animals can be trained, on commands, to remain still. |
A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal an synoptic picture(气象图) of conditions in the atmosphere at a given time.
All students of geography should to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts and all climate conditions in general. Twice a month it issues a 30-day “outlook” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These outlooks are based on an analysis of the upper air levels.
With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(气象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.Which is not mentioned in this passage in the following about one characteristic of weather?
| A．Fronts. | B．Temperature change. | C．Wind speed. | D．Frost. |
The observation of weather conditions by satellites is advantageous because
_______.
| A．it is modern and sophisticated |
| B．it used electronic instruments |
| C．it enables man to alter the weather |
| D．it gives the scientists information not obtained readily otherwise |
The word “interpret” in Paragraph 2 most probably means _______
| A．explain | B．present | C．modify | D．illustrate |
In Europe people hold the fork in the left hand and the knife in the right throughout the meal, a system that is generally agreed to be more efficient than the American zigzag（曲折的）method. Americans hold both the fork and the knife in their right hands throughout the meal, so they continually change their forks to the left hand when they have to cut their meat. It seems to be funny for the Europeans to see Americans busy changing their dinner sets, making a lot of noises. A few explanations for this American style are as follows:
(1)Americans are practical and efficient. Since most of us are right-handed, it is reasonable to keep our working tools at all times in the right hand that can use them most efficiently.
(2)Americans, the master of the New World are rebels（叛逆者）.They use the zigzag method to break the rules in the Old World and in this way they are thumbing their nose at Mother England. Americans are a restless kind. They do not like to sit in one spot for very long when dining.
(3)Forced to do so, they respond by “playing” with the silver.
Whatever the reason for the practice, it is now certainly as American as apple pie. Europeans recognize this and are quick to attack it as evidence of American innocence（无知）of form. Arguments against the zigzag method rest not only on grounds of efficiency but also on those of tradition. In Old World dining, the knife is held in the right hand continually because it can serve as an instant defense against the uninvited intruders（入侵者）.However, such alertness（警觉） is out of place in the New World, as every American believes that this is the home of the brave. Americans juggle their silverware, perhaps, to show that they are not afraid and that one of them holding a fork is worth any number of them holding blades（刀）.Americans use _______ to hold their fork to pick up the salad.
| A．the right hand | B．the left hand |
| C．both hands | D．either of the two hands |
As the masters of the New World, Americans use a different cutting method from that in the Old World to _______.
| A．show their independence of Mother England |
| B．show their disrespect to Mother England |
| C．add a new tradition to those in Mother England |
| D．show off their creativeness to Mother England |
In the sentence, the word “juggle” probably means _______.
| A．hold | B．play with | C．pick up | D．lay down |
Which of the following statements is NOT true?
| A．European people hold the fork in the left hand and the knife in the right hand. |
| B．The zigzag eating method is related to American characteristics. |
| C．The zigzag eating method has become an American feature. |
| D．European people will use the American method because of its efficiency. |
Awareness Weeks（认知宣传周）have become a regular part of Britain's cultural landscape over the past few years. They started back in 1957,when one charity（慈善机构）,Christian Aid, decided to make all its money-raising efforts on one time of year. It was thought that by doing this they would get more publicity for their cause.
They were right, and soon other charities and campaign groups followed them. These days, most donations to charity are not collected on the streets. So instead of just asking for money, charities prefer to spend their time “raising awareness”—spreading knowledge of the work they do or the cause they support. They also compete with businesses and trade groups who use awareness weeks as marketing campaigns for their products.
There are now 500 awareness weeks held every year in the UK. No week goes by without one group or another trying to make the British public aware of something, with most held in May or October.
The danger with all these awareness weeks is that people start to become cynical(不信任).Take National Smile Week, it seems like a great idea. Let's all make each other's life a little bit happier with a friendly smile. But really it's just a group of dentists and cosmetics companies trying to sell us toothpastes. It's enough to make you want to start National Forget About It Week.
“People feel that many awareness campaigns are just marketing exercises,” says Ms Ormiston, who edits the Awareness Campaign Register, a newsletter which encourages people who run Awareness Weeks to become more aware of each other.“But 90 per cent of campaigns are run by traditional charities or not for groups to make money.”
“There's still no official group for awareness campaigns,” says Ms Ormiston.“People can do what they like, whatever the size of their budgets（经费）or their public relations machines allows.”
This situation has led to calls for laws to stop real charities having their efforts overshadowed by marketing campaigns. This could be done by making the two groups hold their weeks at different times or stopping businesses running imitation(模仿) charity campaigns.
But there is another way. Maybe it's time for National Weak Awareness Week, especially for people whose awareness of Awareness Weeks is weak.What's the main purpose of awareness weeks run by charities in Britain?
| A．To raise money for charities. |
| B．To spread knowledge of charities. |
| C．To take up marketing campaigns. |
| D．To advertise their goods for sale. |
Why do people start to become cynical about awareness weeks?
| A．Too many awareness weeks make people feel bored. |
| B．People feel many awareness weeks are just for marketing exercises. |
| C．People have a weak awareness of awareness weeks. |
| D．Awareness weeks are held too often and too much money is raised. |
What does Ms Ormiston think about awareness weeks?
| A．Most of the awareness weeks should not be for making money. |
| B．Official groups should take the place of charities in awareness campaigns. |
| C．People can do what they like in awareness weeks. |
| D．People can get larger budgets through awareness campaigns. |
