A.or
B.in other word
C.that is
D.however
The word "television" can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a complete system of electronics, television provides the capability of converting an image into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reconstructed into that same image.
Television is more than just an electronics system, however. It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool for reaching other human beings.
The field of television can be divided into two types. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques.
Traditionally, television has been a medium of the masses. It has been with us for about thirty- seven years in a form. similar to what exists today. During those years, it has been controlled mostly by the broadcast networks, ABC, NBC and CBS, who have been the major suppliers of news, information, and entertainment. These giants of broadcasting have actually not only shaped television as a source of entertainment, but placed our role in this active medium as the passive viewer.
What is the topic of the passage?
A.The role of television in today's society.
B.The marriage of broadcasting giants.
C.Recent changes in modern technology.
D.The content of broadcast television programs.
This involves a change of attitude in many ways. Although the process has been going on since you went to middle school, the biggest change is going to take place. Now, instead of taking several subjects, you have chosen one major subject because you find it interesting and worth exploring further. The choice was yours. You also have the goal of getting a degree . The degree and the stages you have to pass through to achieve it give you motivation, even though it may become weak from time to time, and not all parts of the course will be exciting; a sure way to lose interest is to do too little work. It is a law of diminishing returns - the less work you do, the less interest you will have and the more bored you will become. So, regular work is needed to keep up your interest as well as to keep pace with new work.
Another change is in the relationship with teachers. This may well have changed during middle school and high school, but now the whole context is different. You are no longer forced to slay in school all day, and apart from your class time, you organize your own time and place for studying. You are there to study (an active process) rather than to be taught (passive). Your teachers may or may not urge you, but they do want you to share their interest in the subject and they want you to succeed.
Some activities, like discussing and reading, are basic to studying. Make sure that you are doing these efficiently.
Group discussions give you a chance to train yourself to speak and discuss more effectively.
Theywill fail in their purpose if you keep silent—and if you start off this way, the harder it will become to get out of the situation of being the non-speaking member of the group. In the future you are almost certainly going to have to be good at speaking, so get into the way of talking about your subject now. This is actually more fun than sitting being silently miserable because you are not saving anything. Nobody will think what you say is foolish. Everyone will be thankful not to face awkward silence.

, although I still hold that it is essential for everyone in the world today. As a top junior student in my college, I was asked to make a speech on how to learn English well. Standing in front of the audience facing so many freshmen, I was trembling. I didn’t remember any word that I had prepared. I ran out of the conference room without finishing my speech, leaving everyone puzzled. I cried that night in my room, feeling that I was a loser. Studying takes so much of my time that I feel unable to really develop myself. I am just storing knowledge; yet fail to communicate with others. I have received many awards in school, but they don’t necessarily reflect anything about me. I don’t know how to socialize. When I leave
school I fear I will be of no use to society.

A work plan is an important tool to tell what tasks to do, when to finish, who to take, where to go and how to get there. The work plan organizes your task with a timetable of what, when and how a job needs to be done. Within the team, a work plan can tell each member what is being done and why.

Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the plummeting prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.
In many parts of the world renewable energy is already a principal energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.
President Trump has underlined fossil fuels – especially coal – as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation – and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.
The question "what happens when the wind doesn’t blow or the sun doesn’t shine?" has provided a quick put-down for skeptics. But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.
The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now, this massive investment could change the picture rapidly in coming years.
While there’s a long way to go, the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up – perhaps just in time to have a meaningful effect in slowing climate change. What Washington does – or doesn’t do – to promote alternative energy may mean less and less at a time of a global shift in thought.
26、The word "plummeting" (Line 3, Para 2) is closest in meaning to_____.
A.stabilizing
