For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料電池).
But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.
The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(鉑). The membrane separates the electrons(電子) from the protons(質(zhì)子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.
Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.

The changing food of early humans
Some people believe that greed and selfishness has become the basis of modern society, and we should return to the old traditions of family and community then we will have a better life. To what extent do you agree or disagree with the above opinion?
In this fast-paced world, many values are undergoing major changes. While people traditionally prioritize caring, sharing and generosity in life and work, modern people seem to be more self-absorbed and self-concerned.
Modern people act selfishly to survive the harsh competition of life. They say that it is a jungle out there. To survive, you have to fight with whatever means that come handy. Obviously greedy and selfishness go perfectly well with such ideas. In a company, employees do everything they can to get better pay and higher position, even at the cost of colleagues. We are in any way advocating any selfish conduct. It is just that people are pressured to act in a certain way due to outside influences.
In spite of common practice, it is hard to conclude that modern society is built on greed and selfishness, both of which are not newly invented vocabulary. In ancient times people also did greedy and selfish things though such behaviors were more condemned then. But we can not ignore the fact that people in the past lived a relatively more isolated life and faced less pressure compared with their modern counterparts.
Are we happier to share with others and be generous to them? There is no fixed answer either. Some people take great pleasure helping and giving to others while others feel happy doing the opposite. But I personally think that people should not be too selfish. Caring for others can actually encourage the development of a mutually beneficial relationship.
In conclusion, modern people appear to be more self-centered than those in the past due to strong outside pressure. However, we should encourage people to know the importance of being caring and generous and to build a mutually beneficial relationship with others.

When it comes to studying, some students may have different study habits, and some ways of studying may work for one and may not for another student. However, there are certain basic rules that can prove to be effective(有效的) in studying for an exam.
Make a plan for how to develop good study habits that last long. A plan should include a schedule(時(shí)間表) on when to study. It doesn’t have to be fixed(固定) and can be changed in case something more important and unexpected comes up. Start with a weekly schedule and determine which period of the day is filled with classes. Use some of the remaining time to study. When creating（制定） the schedule, one should include laboratory activities and extracurricular(課外的) work and take care of personal things and the job if there is one.
Study when one is fully awake and energetic（精力充沛）; it is recommended. Study for no less than 30 to 90minutes after a meal or two hours every day. If one is tired from work and decides to study, it may not be effective, especially if one finds the subject too difficult. It will only give stress and that night might only be forgotten in the next morning when he wakes up. For some students, they can study anywhere if they want; it could be in the library, study rooms or private rooms. A place where one can to focus attention on one’s study is recommended.
Make friends with those that are also eager to learn and pass the exam or achieve good grades. However, one has to balance（平衡） the time to spend with friends. Have and keep a healthy relationship with them.
Take down notes during the class. The hints(暗示) of some questions teachers give will come out in the exam. Sometimes they repeat the topic more than twice, so pay more attention in class. If one does not understand the topic, don’t hesitate(猶豫) to ask questions. A failure in communicating is one of the most common mistakes among students.
Rewrite notes taken from the class. It will help remember the topics that have been discussed and will give one more new ideas. For some students, they find that rewriting notes is very effective.
Take a five-minute break or go out and get some fresh air once in a while when studying. It will relax the mind and help one think better. Do come back to study after taking a short break.

Host family accommodation means that hosts treat the student as a full member of the household, eating together with the student and sharing the common living areas with him/her. No more than three adult students or four junior students will be accommodated in host family accommodation at one time.
Host family accommodation remains popular among international students. It is the most economical and beneficial accommodation for any student. It is also the best way to practice English and learn new cultures. As a result, it is often seen as the number-one choice for its advantages in language study, cultural communication and cost of living. Staying alongside host family enables students to get enough practice during the short time of their study so that their language acquisition is likely to become faster. Living in host families, students are able to spend a lot of time communicating with their "host parents", who are often very hospitable and friendly, and get to know the local way of life, people and culture. Most host families are always ready to help students out in any situation. Often the bonds that are made between international students and their host families endure many years, and are maintained through letters and e-mails. Another advantage is that host family accommodation can sometimes be the least expensive. It attracts students as it ensures them a family type of living at a low cost.
The advantages, however, have not prevented host families from worrying. On the one hand, some host families are losing their unique selling point. One problem is that the majority of hosts in big cities, now generally single and young, have less time available for international students, but the selling point for host family accommodation is communication practice. On the other hand, students' expectations have risen. They are becoming more demanding and asking for more than ever from their accommodation, as they come mainly from high socio-economic groups in their own countries.
To get out of the difficult situation, host families are now making efforts to improve the quality of service. They are trying to make living conditions better, including broadband Internet service, private bathroom, and access to plenty of hot water for long showers. They are also providing students with structured family activities.
It is believed that host family accommodation will keep the popularity vote with international students.

Dear Ralf,
I have received your letter from school and am glad to know that you are becoming responsible(有責(zé)任的)enough to decide on your career.
You are now in the final year of college and are about to start more independent life in society. You know that a generation divides us, and the conditions of social life were different in my days. However, all I can say as advice is that you must select a career wisely. The first consideration is your interest. You can only succeed and feel happy when you do something you enjoy. Your job must be both gainful and satisfying. Then, you must read up on the latest books on the field you are aiming at. Also, you should get familiar with the men and women in the profession of that field. When mind and heart function together, success is inevitable(必然的).
No career is more or less important than any other career. It takes different people to operate the machine of life. I think your interest may lie in the field of making TV programs. Your great communication skills, your active participation(參與) in school plays and the prizes you have won in speech competitions all point in that direction. So a career in Mass Communication and TV film production proves suitable for you. If you succeed and make it in that field, fame and treasure will both follow.
Think a thousand times before making any final decision regarding your career. Anyhow, I want you to be a man of success.
I know that you are mature(成熟的) enough to think for yourself.
With all the best wishes!
Your loving father

Communication Principles
How you see yourself can make a great difference in how you communicate．“Every individual exists in a continually changing world of experience of which he（or she）is the center”．Many communication scholars and social scientists believe that people are products of how others treat them and of the messages others send them．But every day we experience the centrality of our selves in communication．A student．for instance，may describe a conflict with a teacher as unfair treatment：“I know my teacher doesn’t like the fact that I don’t agree with his opinions．a(chǎn)nd that’s why he gave me such a poor grade in that class．”The teacher might say the opposite．Each person may believe that he is correct and that the other person’s view is wrong．
The concept of serf originates in communication．Through verbal and nonverbal symbols, a child learns to accept roles in response to the expectations of others．You establish self-image。The sort of person you believe you are，by how others think of you．Positive，negative，and neutral messages that you receive from others all play a role in determining who you are．Communication itself is probably best understood as a dialogue process．Our understanding of communication comes from our interactions with other people．In a more obvious way．communication involves others in the sense that a competent communicator considers what the other person needs and expects when selecting messages to share．So，the communication begins with the self，as defined largely by others，and involves others，as defined largely by the self．
Communication Occurs almost every minute of your life．If you are not communicating with yourself（thinking，planning，reacting to the world around you），you are observing others and drawing inferences from their behavior．Even if the other person did not intend a message for you．you gather observations and draw specific conclusions．A person yawns and you believe that person is bored with your message．A second person looks away from you and you conclude that person is not listening to you．A third person smiles（perhaps because of a memory of a joke he heard recently） and you believe that he is attracted to you．We are continually picking up meanings from others’ behaviors and we are constantly providing behaviors that have communicative value for them．
More often than not，you may have hurt someone accidentally and you may have tried to explain that you did not mean that. You may have told the other person that you were sorry for your statement．You may have made a joke out of your rude statement．Nonetheless，your comment remains both in the mind of the other person and in your own mind．You cannot go back in time and erase your messages to others．Communication cannot be reversed（倒退），nor can it be repeated．When you tried to re—create the atmosphere，the conversation，and the setting，nothing seemed right．Your second experience with a similar setting and person made far different results．
