【题目】As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free-form gestures–sweeping fingers in shapes across the screen of a smart phone—can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords.

“All that it takes to steal a password is a quick eye,” said one of the researchers of the study. “With all the personal information we have on our phones today, improving their security is becoming increasingly necessary.” In developing a secure solution to this problem, the researchers studied the practicality of using free-form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity.

The researchers carried out a create-test-retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free-form gestures as passwords.

To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens(触摸屏), attempt to steal a free-form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks.

Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free–form passwords in the future. They believe this is the first study to explore free-form gestures as passwords. They will soon publish their findings.

1What can we learn about free-form gestures?

A. They are improving mobile security in a way.

【题目】Charles Dickens is often thought of as one of the greatest British writers. February 7 marked the 200th anniversary of his birthday. Yet for many, his language is old-fashioned and his stories often improbable. So why do so many people know and read Dickens today?

One reason is the British government’s insistence that every child studies a Dickens novel at school. Alongside William Shakespeare, Dickens is on every English literature school reading list.

His stories, though often long by today’s standards, are great moral tales. They are filled with colorful characters.

Earlier this month, a ceremony was held in Portsmouth, where Dickens was born. Prince Charles said at the ceremony, “Dickens used his creative genius to campaign passionately for social justice… His characterization (人物刻画) is as fresh today as on the day it was written.”

His books stand out from many other writers because of his insight into human nature. Dickens, like Shakespeare, tells us truths about human behavior. They are as true in the 21st century as they were to his readers in the 19th century.

Readers have returned to Dickens’ books again and again over the years to see what he has to say about their own times.

No surprise then that it was Dickens whom Britons turned to during the economic crisis in the last couple of years. Dickens helped them make sense of a world that was rapidly falling apart. The BBC adapted one of his less well-known novels, Little Dorrit, into a popular television drama that introduced many Brits to the novel for the first time. A dark story about greed and money, it was the perfect illustration of bad times.

As long as Dickens’s novels have something to say to modern audiences, it seems likely that he will remain one of Britain’s best-loved writers.

1In the article, the author intends to tell us ______.

A. why Dickens’ novels still appeal to readers in modern times

B. that Dickens’ works are no longer popular among young people

C. why the British government puts Dickens on school reading lists

D. that Dickens and Shakespeare’s works are required for study at school

2In Britain, people still read Dickens because of ______.

a) romance in his books

b) moral value in his books

c) his colorful characters

d) his insight into human nature

e) government education requirement

f) his prediction of the current economic crisis

A. abdf B. bcde C. bdef D. abed

3We can infer from the article that ______.

A. it’s better to read Dickens in time of difficulty

B. Dickens was a great social observer of his time

C. human nature seems worse during bad times

D. Dickens’s novels are short and easy to read

4Which of the following statements is TRUE?

A. Little Dorrit is one of Dickens’ best-known novels.

B. Dickens’ novels are of greater value during economic crisis.

C. Dickens’ works have gained more popularity than Shakespeare’s

D. Dickens’ novels are still of realistic significance to today’s world.
