31、阅读Passage One，回答B-31到B-35五个问题。请从A、B、C、D四个选项中选出可以填入题干空白处的最佳选项。
Passage One
One of the key challenges in urban architecture over the next 50 years will be figuring out how to squeeze vast numbers of additional people into urban areas that are already extremely crowded. London, for example, will somehow have to deal with a projected 100,000 extra inhabitants every year until 2016. The current plan of building new “satellite towns” of the city causes a lot of problems —but architecture think tanks are working on ambitious solutions that go vertical instead of horizontal in search of space.
In terms of population density, London is one of the least crowded major cities in the world— four times fewer people per square kilometer than Paris, for example, six times fewer than New York and eight times fewer than Cairo. But the fact remains that the city’s population is growing at a rapid rate, and horizontal expansion into the surrounding areas is eating up increasingly important agricultural land, as well as worsening all the transport problems that come with urban growth.
Popular Architecture would propose a radically different solution. The proposal is to go up wards, with vertical towers of considerable size, each representing an entire new town by the time it’ s completed. Each tower would be 1500 meters high. Beyond mere accommodation, each tower would function as an entire town unit, with its own schools, hospitals, parks and gardens, sports facilities, business areas and community spaces. The population density of such a tower could help lower the individual energy requirements of each inhabitant, reducing the ecological impact of the population as a whole.
The village towers are considered as hollow tubes, with large holes to allow light and air through the entire construction. Occasional floor discs spread throughout the height of the building will give inhabitants large central areas in the middle of the tube to use as gathering spaces。
While the building itself is unlikely ever to be seriously considered for construction—imagine the number of elevators it would need, let alone the safety implications of open areas at such heights and with such wind exposure—the concept can serve as a conversation-starter for urban planners looking to face the challenges of the current and coming centuries.

A、build new satellite towns
B、work out ambitious plan
C、design less crowded cities
D、accommodate more inhabitants

36、阅读Passage Two,回答B-36到B-40四个问题。请从A、B、C、D四个选项中选出可以填入题干空白处的最佳选项。
Passage Two
Passwords are everywhere in computer security. All too often, they are also ineffective. A good password has to be both easy to remember and hard to guess, but in practice people seem to pay attention to the former. Names of wives, husbands and children are popular. “123456” or “12345” are also common choices.
That predictability lets security researchers (and hackers) create dictionaries which list common passwords, useful to those seeking to break in. But although researchers know that passwords are insecure, working out just how insecure has been difficult. Many studies have only small samples to work on.
However, with the cooperation of Yahoo!, Joseph Bonneau of Cambridge University obtained the biggest sample to date—70 million passwords that came with useful data about their owners.
Mr Bonneau found some interesting variations. Older users had better passwords than young ones. People whose preferred language was Korean or German chose the most secure passwords; those who spoke Indonesian the least. Passwords designed to hide sensitive information such as credit-card numbers were only slightly more secure than those protecting less important things, like access to games. “Nag screens” that told users they had chosen a weak password made virtually no difference. And users whose accounts had been hacked in the past did not make more secure choices than those who had never been hacked.
But it is the broader analysis of the sample that is of most interest to security researchers. For, despite their differences, the 70 million users were still predictable enough that a generic password dictionary was effective against both the entire sample and any slice of it. Mr Bonneau is blunt: “An attacker who can manage ten guesses per account will compromise around 1% of accounts.” And that is a worthwhile outcome for a hacker.
One obvious solution would be for sites to limit the number of guesses that can be made before access is blocked. Yet whereas the biggest sites, such as Google and Microsoft, do take such measures, many do not. The reasons of their not doing so are various. So it’s time for users to consider the alternatives to traditional passwords.
B-36.People tend to use passwords that are_______.
A、easy to remember
B、hard to figure out
C、random numbers
D、popular names
正确：A

Passage Three
John Lubbock, a British member of the Parliament, led to the first law to safeguard Britain’s heritage—the Ancient Monuments Bill. How did it happen?
By the late 1800s more and more people were visiting Stonehenge for a day out. Now a World Heritage Site owned by the Crown, it was, at the time, privately owned and neglected.
But the visitors left behind rubbish and leftover food. It encouraged rats that made holes at the stones’ foundations, weakening them. One of the upright stones had already fallen over and one had broken in two. They also chipped pieces off the stones for souvenirs and carved pictures into them, says architectural critic Jonathan Glancey.
It was the same for other pre-historic remains, which were disappearing fast. Threats also included farmers and landowners as the ancient stones got in the way of working on the fields and were a free source of building materials.
Shocked and angry, Lubbock took up the fight. When he heard Britain’s largest ancient stone circle at Avebury in Wiltshire was up for sale in 1871 he persuaded its owners to sell it to him and the stone circle was saved.
“Lubbock aroused national attention for ancient monuments,’’ says Glancey. “At the time places like Stonehenge were just seen as a collection of stones, ancient sites to get building materials.”
“Lubbock knew they were the roots of British identity. He did for heritage what Darwin did for natural history. ”
But Lubbock couldn’t buy every threatened site. He knew laws were needed and tabled the Ancient Monuments Bill. It proposed government powers to take any pre-historic site under threat away from uncaring owners, a radical idea at the time.
For eight years he tried and failed to get the bill through parliament. Finally, in 1882, it was voted into law. It had, however, been watered down; people had to willingly give their ancient monuments to the government. But what it did do was plant the idea that the state could preserve Britain’s heritage better than private owners.
Pressure started to be put on the owners of sites like Stonehenge to take better care of them.
B-41. According to the text, Stonehenge in the late 1800s was______.
A、a royal property
B、utterly neglecteD
C、legally protecteD
D、 a public property
