阅读下面短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
Before you buy a jet printer (喷墨打印机), you'd better decide in advance how much printing you need to do. Then you can print test pages using a variety of printers, a good way to get a quick picture of what a machine can really do. After that, check the specification (说明书) carefully. Here are factors to consider.
Resolution: Resolution refers to the number of dots that a printer lays down per inch of paper. Higher - resolution printers theoretically produce more detailed images with more lifelike colors than lower - resolution printers. But resolution doesn't tell the whole tale; some printers are just better at photos while others are better at texts.
Speed: After resolution, the most important factor for many buyers is speed. More money buys a faster printer, which is important if you frequently print long texts.
Duty cycle: This is the number of pages per month a printer can produce without selfdestroying. It differs from a few hundred pages to thousands. Overwork your printer and it will probably break down, always at the worst possible moment. For ordinary home and school use, duty cycle isn't important, but if you are in a busy office, or you are printing drafts (草稿) of a book, spend a few dollars more for a heavier - duty machine.
Ink consumption: Gillette came up with the idea a century ago-sell razors (刮胡刀) cheap and they'll buy your blades (刀片) forever. Printer producers have taken this to heart. In fact, the reason you can buy a decent ink jet for $ 100 is that you'll be buying $30 ink cartridges for life, particularly if you tarn out party invitation, greeting cards, buttons, calendars and other projects. As a rule, low - end printers cost more to operate because their cartridges are smaller and require more frequent replacement.
1．Which of the following can produce the clearest printings of pictures?
[ ]
A．A faster printer with higher resolution.
B．A higher resolution printer.
C．A right kind of printer with higher resolution.
D．A heavier - duty and higher resolution printer.
2．Supposing Smith is a writer, the best printer for him to buy is ________.
[ ]
A．a low-end printer
B．an expensive printer
C．a higher resolution printer
D．a heavier - duty printer
3．In the writer's opinion, you can buy a decent ink jet printer at $ 100 because ________.
[ ]
A．the high price will encourage you to buy $ 30 ink cartridges instead all your life
B．the producer is afraid that you will buy $ 30 ink cartridges instead of the ink jet
C．the low price will keep you buying $ 30 ink cartridges one after another
D．the printer can't work well without the decent ink jet
4．What is the most important in choosing the right ink jet printer?
[ ]
A．Selecting the cheapest one.
B．Buying the most advanced one.
C．Meeting your own requirement.
D．Printing test pages with a variety of printers.

In the 1940s, Pinehaven Park was one of Crafton City's loveliest recreation(娱乐)areas. Over 40 acres of woods and fields were open to the public. In the 1950s, part of the park was taken over by Crafton City's garbage. Fifteen acres were to be used for landfill disposal(理置). As time went on, more and more of the park was used for garage disposal and less for recreation. Two years ago, the park was closed to the public for good. Along with household garbage, industrial chemicals had for years been dumped (倾倒)in the Pinehaven landfill. These poisonous chemicals had begun to seep(渗)back up through the soil. All of Pinehaven Park had become dangerously polluted.
Last year, the fish in the Crafton River began to die. After a series of investigations(研究), it became clear that the people of Crafton City were not to blame. 100～150 miles upstream, big paper mills were dumping industrial wastes into the river. Little by little, the level of poison in the river began to rise. Finally, it became so polluted that the fish themselves could no longer survive.
Downtown Crafton used to be a quiet area. Ten years of remarkable growth changed that in a big hurry. But with Crafton City's new prosperity(繁荣)came a new problem: air pollution. And it is a serious problem. Air pollution levels in Crafton are regularly reaching those of the nation's large industrial cities.
(1)Which of the following best states the central idea of the passage?
[ ]
A．Chemical dumping is a serious threat to Crafton City's soil.
B．The rapid growth of industry has brought air pollution to Crafton City.
C．The disposal of garbage can destroy recreation areas.
D．Industrial growth and progress have resulted in the pollution of Crafton City's water, air, and soil.
(2)According to the passage, what portion of the park had originally been marked for use as a garbage dump?
[ ]
A．Less than half B．Exactly half
C．About one third D．Most of it
(3)As it is used in the passage, the phrase“for good”means ________.
[ ]
A．practically B．for ever
C．thoroughly D．advantageously
(4)According to the passage, one result of dumping industrial chemicals into the landfill was that ________.
[ ]
A．the land became unsafe for humans
B．the animals on the land died
C．the poisonous chemicals were washed into the nearby river
D．the smoke from the chemicals polluted the air surrounding the landfill
