　　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(燃料电池)．

　　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(铂)．The membrane separates the electrons(电子)from the protons(质子)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．

　　We all have goals that we are moving towards and making a great effort to achieve．This is a good thing．Or can it be bad? How many of us never reach our goals and yet we have tried so hard and really thought about nothing else? I believe the mistake most of us make is that we do not focus on our present situation．

　　Let me explain．Most of us see our present situation as a stepping stone that we use simply as a means of reaching our final destination．We don't take time to truly appreciate where we are today and all the great things we already have in our lives．We should focus our attention on the journey and not on the destination, or we will miss the beautiful scenery along the way．

　　Let's use our job as an example．Now most of us want a promotion．We have plans to become the manager or general manager in our companies．Unfortunately, most of us will never reach the goal, but will watch others achieve our goal instead．

　　What we should be doing is focusing on the job we are currently in now．Forget where we want to get to and just focus on the present．You see, what we can control is our performance in our current job．We can decide to be the best we possibly can in our current job．Now this may mean further education to have the skills we currently do not have．It may mean working harder to produce better results than our colleagues．It could simply be a change of attitude, such as stopping complaining and becoming a more devoted and supportive employee．By doing our current job to the best of our abilities, we in fact give ourselves the best chance of promotion．

　　So the best thing for all of us to do to achieve our goals is to just focus on what we have and where we are now．Do the best and be the best we possibly can in our current situations, and we will give ourselves the very best chance of reaching our goals in the future．We have heard the old sayings and they are true： “Rome wasn't built in a day．”, “Patience is a virtue”, and so on．

　　Have patience, have appreciation of what we already have, and take time to help ourselves be the very best we can．Do these things and we will all reach our goals, but more importantly, we will enjoy our life every day．

　　As a saying goes, “If you have a good friend, your joys are doubled and your sorrows are halved” ．Friends are a helping hand, a comforting shoulder to lean on, a patient ear to listen to you and most importantly, a warm and loving hug to embrace(拥抱)you．Man is a social animal by nature．We all need friends, as they are there for us when we need support, just as we are there for them whenever they need us．Therefore, it is necessary for you to know how to make friends．

　　The first step is to open yourself up．If you want to make good friends, you should be able to share your thoughts and feelings with other people first．Only when you share something of yourself with others, can you begin making friends．When your friends open a conversation with you, they are usually expecting you to share information in return．That is to say, when you are in a conversation, you'd better express your own thoughts and feelings．If a conversation is one－sided, the person doing all the talking may think the other person is not interested in what he is saying．So, when talking with your friends, be sure that the conversation is a two－way street．

　　One of the most important keys to building a solid friendship with other people is to listen to them－really listen．When your friends tell you something that happened to them or complain(埋怨)about a situation, they are usually not looking for agreement but just want to be heard．So don't try to change their mind or solve their problems, just let them know that you are listening to them．

　　Respecting your friends is also important to keep your relationships healthy and strong．Looking at your friends while they are talking to you is one way to show your respect, as they will feel that what they are saying is important to you．

　　Unconditional support and encouragement is one of the things which friends have．True friendship means offering a shoulder when they need it, crying with them when they are sad, and laughing with them when they are happy．Only in this way, can the tree of friendship last for a long time．

Directions：Read the following passage．Fill in the numbered blanks by using the information from the passage

　　Write NO MORE THAN THREE WORDS for each answer．

　　Since the earliest civilizations, people have controlled rivers to meet society's demands．Today, rivers are controlled for many reasons, primarily to maintain reliable water supplies for daily, agricultural and industrial needs, for power generation, for navigation(航行), and to prevent flooding．

　　River control is achieved by channelization, a term that covers a range of river engineering works, including widening, deepening, straightening and stabilization of banks, and by the construction of dams．

　　An important period of channelization took place in Europe during the l9'th century, when many large rivers were straightened and their beds deepened．One of the most dramatically changed was the Tisza River, a branch of the Danube that flows through Hungary．The controlling of the Tisza, designed to reduce flooding and make land for agriculture, included cutting off more than 100 meanders(河曲), shortening the river's length by nearly 400 kilometers．

　　One of the most common ways in which people control rivers is by damming them．The past 50 years or so has seen an increase in dam construction worldwide, and at the beginning of the 21^st century, there were about 800, 000 dams globally, some towering more than 200 meters in height．

　　Despite their successes, many dams also cause significant environmental changes that prove harmful．Some particularly deep reservoirs(水库)can bring about earthquakes due to the stress on their bottom rocks caused by huge volumes of water．Downstream of a reservoir, the river is certainly influenced in many ways：water volume, speed and quality are all affected, leading to changes in the landscape and among plants and animals．
