W: Thank you.
M: Well, we hear it a lot in the news these days: "Recycle newspapers and save a tree. Collect bottles and cans so they can be reused in the manufacturing of new products." But how to promote the recycling movement？ Can you give us some suggestions？
W: I think there are three essential keys.
M: What is the first one？
W: The first key is to have a more informed public, that is, to raise public awareness about the recycling process, to explain the kinds of materials that can be recycled, and provide ways on how to properly dispose of them. Local governments should educate the public on how to properly sort reusable materials from those, like waxed paper, carbon paper, plastic material such as fast food wrappers, that can't be recycled very easily.
M: Then what is the second key？
W: The second is the development of improved technology. Technological progress has been made on many fronts, but governmental agencies need to step up their support for companies involved in recycling by providing tax incentives, low-cost loans, or even grants to upgrade equipment and to encourage further research.
M: So what about the third essential key？
W: The final key is to develop a greater demand for recycled materials. This means increasing demand for the growing surplus of resources waiting to be recycled.
M: Recycling is a crucial link protecting our planet. The three keys Mrs. Green mentioned are important ways to achieve this end. Thanks for joining us, Mrs. Green.
W: You're welcome.

A．Keys to paper recycling.
B．Importance of recycling.

听力原文： How can a speaker successfully hold an audience's attention during his speech？ What is the secret？
First, find out about the audience and what they need to know. Plan what you're going to say and say it clearly and concisely. (33) A good speaker uses various signals to help hold the audience's attention and make the information clear. One type of signal is to introduce a list with a phrase like There are three things we have to consider. The speaker then says what the three things are and talks about each one at the required level of detail.
Another signaling technique is to give a link between parts of the presentation. Say where one part of the talk finishes and another starts. For example, a well organized presentation usually contains different parts and progression from one part to the next must be clear, with phrases like that's all I want to say about the development of the product. Now let's turn to the actual marketing plan. This technique is very helpful to the audience, especially those who are mainly interested in one part only. Another type of signaling is sequencing of information. This usually follows a logical order, perhaps based on time. Key words in sequencing information are first, then, and so on.
(34) Still another technique which helps to emphasize key points is careful repetition. Examples are As I've already said, there is no alternative but to increase production by 100 per cent...
A final point concerns timing and quantity of information. (35) Psychologists have suggested that concentration is reduced after about twenty minutes without a break or a change in activity. Furthermore, audience should not overburdened with technical details or given too many facts to remember. It is claimed that to ask people to remember more than three things in a five minutes' talk is too much.
Every speaker needs to think about exactly how much information of a particular type a specific audience is likely to absorb and to plan accordingly.
33．How can a good speaker hold the audience's attention？
34.How can a good speaker emphasize the key points in his activity？
35.How can a speaker lengthen the audience's attention？
(30)
A．By telling a vivid story.
B．By a well-organized presentation.
C．By using various signals.
D．By a logical order.
截取一段明文如下:
The Mutual Information Analysis (MIA) is a generic side channel distingui she that has been introduced at CHES 2008. This paper brings three contributions with respect to its applicability to practice. First, we emphasize that the MIA principle can be seen as a toolbox in which different (more or less effective) statistical methods can be plugged in. Doing this, we introduce interesting altematives to the original proposal. Second, we discuss the contexts in which the MIA can lead to successful key recoveries with lower data complexity than classical attacks such as, eg. using Pearson's correlation coefficient. We show that such contexts exist in practically meaningful situations and analyze them statistically. Finally, we study the connections and differences between the MIA and a framework for the analysis of side- channel key recovery published at Eurocrypt 2009. We show that the MIA can be used to compare two leaking devices only if the discrete models used by an adversary to mount an attack perfectly correspond to the physical leakages.

A high level of private sector participation is central to APEC's success and makes APEC unique amongst regional and international organizations. Time APEC Business Advisory Council (ABAC), established in 1995, is composed of up to three members from each economy, appointed by APEC Leaders. In recognition of the key role of small and medium-sized enterprises (SMEs) in all APEC economies, most members reserve one ABAC position for an SME representative.
ABAC meets several times each year and publishes an annual report recommending initiatives to improve APEC’s business and investment climate. The report is presented to the APEC leaders Meeting and its recommendations guide APEC in designing its programs.
The annum APEC CEO Summit is another forum where regional business leaders can interact with APEC leaders and address key issues affecting business in the region.

Albert Einstein was the first to suggest the existence of stimulated emission in a paper published in 1917. However, for many years physicists thought that atoms and molecules always were much more likely to emit light spontaneously and that stimulated emission thus always would be much weaker. It was not until after the Second World War that physicists began trying to make stimulated emission dominate. They sought ways by which one atom or molecule could stimulate many others to emit light, amplifying it to much higher powers.
The first to succeed was Charles H. Townes, then at Columbia University in New York. Instead of working with light, however, he worked with microwaves, which have a much longer wavelength, and built a device he called a "maser", for Microwave Amplification by the Stimulated Emission of Radiation. Although he thought of the key idea in 1951, the first maser was not completed until a couple of years later. Before long, many other physicists were building masers and trying to discover how to produce stimulated emission at even shorter wavelengths.
The key concepts emerged about 1957. Townes and Arthur Schawlow, at Bell Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At about the same time, similar ideas crystallized in the mind of Gordon Gould, then a 37-year-old graduate student at Columbia, who wrote them down in a series of notebooks. Townes and Schawlow published their ideas in a scientific journal, Physical Review Letter, but Gould fried a patent application. Three decades later, people still argue about who deserves the credit for the concept of the laser.
The word "intervention" (Line 3, Para. 1) can best be replaced by ______.
A．need
B．device
C．influence
D．reproduction

What are the symptoms？ It might seem logical that the most obvious symptom of depression would be sadness, but many depressed children say they don't feel sad or gloomy. Interestingly, one of the key signs of depression in children is [34] irritability(易怒). Children may be depressed if [34] they have trouble getting along with other kids and family members or have dramatic swings in mood. Other signs of depression include lack of energy, inability to concentrate, [34] poor performance in school, a sense of hopelessness and helplessness, and frequent complaints about physical ailments like headaches or stomachaches.
If your child exhibits any symptoms of depression, ask yourself three questions: [35] Is this behavior. new？ Is it long-lasting (going on for several weeks or more)？ Are the symptoms interfering with his ability to function at home, in school, or with his friends？ If you answer yes to any of those questions, you should probably have your child evaluated by a child or adolescent psychologist, psychiatrist, or other licensed mental health professional trained to work with children and adolescents.

A．The child seems sad.
B．His or her sadness lasts for a rather long period of time.
C．The child occasionally feels blue or down.
D．He or she feels life has its ups and downs.
听力原文： My child seems sad. Is he suffering from depression？ Not necessarily: Normal sadness or grieving is not depression. Don't worry if your child occasionally feels blue or down. Life has its ups and downs, and it's normal for children to grieve over a loss or feel sad for a few hours or days at a time. But if his melancholy lasts for more than a couple of weeks or seems to interfere with his regular activities and relationships, he may be clinically depressed. Depression is far more than a temporary change in mood; it's marked by a sense of hopelessness and a lack of energy and enthusiasm that can last for weeks, months, or (in rare cases) even years at a time. The good news about depression is that it's almost always treatable. The key is identifying the problem and getting help. What are the symptoms？
