A.A bond issue is a technique for subdividing a very large loan into many small, transferable units.
B.Bond interest payments are contractual obligations, whereas the board of directors determines whether or not dividends will be paid.
C.As interest rates rise, the market prices of bonds rise; as interest rates fall, bond prices tend to fall.

第5题
[A]Graham has become increasingly busy, supplying flat-packed weathervanes to clients worldwide.
[B]Graham decided to concentrate his efforts on a weathervane business. He had served an apprenticeship as a precision engineer and had worked in that trade for 15 years when he and his wife, Liz, agreed to swap roles—she went out to work as an architectural assistant and he stayed at home to look after the children and build up the business.
[C]Last month, a local school was opened with his galleon ship weathervane hoisted above it.
[D]“For centuries, weathervanes have kept communities in touch with the elements, signaling those shifts in wind direction that bring about changes in the weather,” he explains.
[E]Graham has no plans for expansion, as he wants to keep the business as a rural craft.
[F]Graham has now perfected over 100 original designs. He works to very fine detail, always seeking approval for the design of the silhouette from the customer before proceeding with the hand-cutting.
第6题
A.the cost is lowered
B.people need it to reduce damages
C.meteorologists can make full use of the new technologies
D.conventional weather forecasts are got rid of

Irvine-Halliday, an American photonics engineer, was not surprised. He chose to use LED bulbs because they are rugged, portable, long-lived, and extremely efficient. Each of his lamps produces a useful amount of illumination from just one watt of power. Villagers use them about four hours each night, then top off the battery by pedaling a generator for half an hour. The cool, steady beam is a huge improvement over lamps still common in developing Countries. In fact, LEDs have big advantages over familiar incandescent (白炽的)lights as well--so much so that Irvine-Halliday expects LEDs will eventually take over from Thomas Edison's old lightbulb as the world's main source of artificial illumination.
The dawn of LEDs began about 40 years ago, but early LEDs produced red or green glows suitable mainly for displays in digital clocks and calculators. A decade ago, engineers invented a semiconductor crystal made of an aluminum compound that produced a much brighter red light. Around the same time, a Japanese engineer developed the first practical blue LED. This small advance had a huge impact because blue, green, and red LEDs can be combined to create most of the colors of the rainbow, just as that in a color television picture.
These days, high-intensity color LEDs are showing up everywhere such as the traffic lights. The reasons for the rapid switchover are simple. Incandescent bulbs have to be replaced annually, but LED traffic lights should last five to yen years. LEDs also use 80 to 90 percent less electricity than the conventional signals they replace. Collectively, the new traffic lights save at least 400 million kilowatt-hours a year in the United States.
Much bigger savings await if LEDs can supplant Mr. Edison's bulb at the office and in the living room. Creating a white-light LED that is energy-saving, cheap and appealing has proved a tough engineering challenge. But all the major lightbulb makers--including General Electric, Philips, and Osram-Sylvania -- are teaming up with semiconductor manufacturers to make it happen.
From the first paragraph, we can see that Dave Irvine-Halliday______.
A.is a mountain climber
B.went to that village to repair the lamps
C.found the villagers were using the lamps he had given them
D.has visited the small village several times
