In a recent study, researchers have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, make the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use. Combining all the energy input totals for treatment and distribution, researchers found that producing bottled water requires between 5.6 and 10.2 million joules(焦耳) of energy per liter, depending on transportation factors. That's up to 2, 000 times the energy required to produce tap water.
To break down the energy requirements, researchers found that producing the plastic bottles and transporting the bottles greatly dominated(控制) the energy input. Although some companies are experimenting with producing lightweight bottles or using recycled materials, the researchers calculated that the manufacturing cost is about 4 million joules of energy per plastic bottle weighing 38 grams, and the cap weighing 2 grams.
“Our previous work had suggested that bottled water production was an energy intensive process, but we were surprised to see the results, ” the researchers said.
Transportation costs vary depending on the distance and mode of transport and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US:” spring water” which comes from an underground spring and “purified water”,which is city tap water that has received further treatment. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck requires about 4 million joules per liter for transportation. For the spring water, the transportation energy equaled (in the case of Fiji) the energy required to produce the bottle.
With this data, the researchers hope that future studies will have the ability to make specific estimates for different situations, and possibly find ways to cut energy costs.From the first Paragraph we can know that the energy required to ______.
| A．produce bottled water includes the energy required to drink it |
| B．distribute bottled water includes the energy for producing the bottles |
| C．distribute bottled water is much smaller than the energy for treating it |
| D．produce bottled water is much smaller than the energy for producing tap water |
To reduce the energy required to produce bottled water, some companies are trying ______.
| A．to fill tap water into the plastic bottles directly |
| B．to replace the plastic bottles with metal containers |
| C．to produce lightweight bottles with recycled materials |
| D．to use bicycles to transport and deliver bottled water locally |
What's Paragraph 4 mainly talking about?
| A．Treatment of bottled water needs no energy input at all. |
| B．Bottled water production is an energy intensive process. |
| C．Transportation of bottled water takes up the most energy input. |
| D．Production of the plastic bottles greatly dominated the energy input. |
We can infer from the passage that ______.
| A．there are two main kinds of bottled water in the US |
| B．world consumption of bottled water has been increasing |
| C．transportation costs have something to do with the mode of transport |

Today, roller skating is easy and fun. But many years ago, it wasn’t easy at all. Before 1750, people never tried skating on wheels. That changed because of a man named Joseph Merlin. Merlin’s work was making instruments. In his free time he liked to play the violin. Merlin was a man with many ideas and many dreams. People called him a dreamer.
One day Merlin received an invitation to go to an important party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think. He wanted to find a way to make a wonderful entrance at the party. Merlin had an idea. He thought that he would attract a lot of attention if he could skate into the room.
Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skate shoes. Merlin was very proud of them. He dreamed of arriving at the party and skating into the room while playing the violin. He was sure that everyone would be very surprised.
On the night of the party Merlin rolled into the room, playing his violin. Everyone was really surprised to see him. There was just one problem. Merlin had no way to stop his roller skating. He rolled on, playing the violin. Then, with all eyes on him, Merlin hit into a huge mirror on the wall. The mirror broke into many pieces with a very loud noise.

To master a language one must be able to speak and understand the spoken language as well as to read and write．Lenin and his wife translated a long English book into Russian but when they went to England in 1902, English people couldn't understand a word Lenin and his wife said, and Lenin and his wife couldn't understand what was said to them．This shows the importance of spoken language．
Speaking, of course can't go without listening．If you want to pronounce a word correctly, first you must hear it correctly．The sounds of Chinese and English languages are not exactly the same．If you don't listen carefully, you'll find it difficult or even impossible to understand the native speakers．
Well, what about writing﹖ Like speaking, it's to exchange ideas．People usually use shorter words and shorter sentences in their writing．
The important thing is to make your idea clear in your mind and then to write it in a clear lively language．
Chinese students read too slowly．If you read fast, you understand better．If you read too slowly by the time you have reached to the end of a page you have forgotten what the beginning is about．When you meet with new words don't look them up in the dictionary．Guess the meaning to form the context. You may not guess quite correctly the first time but as new words appear again and again in different context their meaning will become clearer and clearer. If you look up every word you'll never finish a book．
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they're studying. They should study those subjects in the foreign language not only in translation．In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time．In England Lenin ．
| A．could be understood by Englishmen |

In the first paragraph the writer told us ．
| A．how to speak English |
| B．how to read and write |
| C．why English people couldn't understand the Lenins |
| D．spoken English is important |
In the fifth paragraph the writer advised us on ．
| A．how to guess the meaning of the words |
| B．how to read fast |
| C．how to look up new words in the dictionary |
| D．how to read carefully |
“Kill two birds with one stone” means ．
| A．to get some particular knowledge |
| B．to get more than what one pays |
| C．the stone is very useful |
| D．the birds are blind enough |
In the last paragraph the writer advised us ．
| A．to kill two birds with one stone |
| B．to learn two languages at the same time |
| C．to study all the subjects in a foreign language |
| D．to get some knowledge of the foreign country whose language we are studying |

Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.
Different cultures emphasize (强调) the importance of relationship building to a greater or less degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in “small talk”,usually over a glass of tea, before they do any job. In many European countires--- like the UK or France--- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.
Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected may speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realised that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.
Even within Northern Europe, cultural diffeerences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.
People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment (多元文化环境)will offer a wonderful chance for us to learn from each other.In some countires, eating together at restaurants may make it easier for people to ___________.
| A．develop closer relations | B．share the same culture |
| C．get to know each other | D．keep each other company |
