early是什么意思，有什么用法？
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.

First, let's talk about culture. The difference between the mobile phone and its parent, the fixed-line phone, you get whoever answers it.
This has several implications. The most common one, however, and perhaps the thing that has changed our culture forever, is the "meeting" influence. People no longer need to make firm plans about when and where to meet. Twenty years ago, a Friday night would need to be arranged in advance. You needed enough time to allow everyone to get from their place of work to the first meeting place. Now, however, a night out can be arranged on the run. It is no longer "see you there at 8", but "text-me around 8 and we'll see where we all are".
Texting changes people as well. In their paper, "Insights into the Social and Psychological Effects of SMS Text Messaging", two British researchers distinguished between two types of mobile phone users: the "talkers" and the "texters"--those who prefer voice to text message and those who prefer text to voice.
They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality. Texters were likely to report that their family would be surprised if they were to read their texts. This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.
Another scientist wrote of the changes that mobiles have brought to body language. There are two kinds that people use while speaking on the phone. There is the "speakeasy": the head is held high, in a self-confident way, chatting away. And there is the "spacemaker': these people focus on themselves and keep out other people.
Who can blame them？ Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So, it is understandable if your mobile makes you nervous. But perhaps you needn't worry so much. After all, it is good to talk.
When people plan to meet nowadays, they ______.
A．arrange the meeting place beforehand
B．postpone fixing the place till last minute
C．seldom care about when and where to meet
D．still love to work out detailed meeting plans

听力原文： American colleges and universities consider a number of things about a student who wants to be admitted. Experts on the subject say the most important thing is the student's high school record. Admissions officers look not only at the grades that the student has earned. They also look at the level of difficulty of the classes.
A student's interests and activities may also play a part in getting accepted. But in most cases another consideration is how well the student did on college entrance exams. This week in our Foreign Student Series Program, we discuss two of these tests: the SAT and the ACT. Most American schools accept either one.
The SAT measures reasoning skills in mathematics and language. Students have almost four hours to complete the SAT. The newest part is an essay. Students have 25 minutes to write an answer to a question.
Students may also need to take SAT subject tests in areas like history, science and foreign language.
The ACT is an achievement test. It is designed to measure what a student has learned in school. Students are tested in mathematics, English, reading and science. A writing test is offered but not required. Without it, the ACT takes about three hours to complete. The essay part adds 30 minutes.

A．The grade of the ACT or the SAT.
B．The high school the applicant studied.
C．The high school record.
D．The entrance examination.
And yet, city life isn't easy．Now scientists have begun to examine how the city affects the brain, and the results are depressing．Just being in an urban environment, they have found, impairs(损害)our basic mental processes．(79) After spending a few minutes on a crowded city street, the brain is less able to hold things in memory, and suffers from reduced self-control．While it's long been recognized that city life is exhausting, this new research suggests that citied actually dull our thinking, sometimes dramatically so.
One of the main forces at work is a complete lack of nature, which is surprisingly beneficial for the brain．Studies have demonstrated, for instance, that hospital patients recover more quickly when they can see trees from their windows, and that women living in public housing are better able to focus when their apartments overlook a lawn．Even these glimpses of nature improve brain performance, it seems, because they provide a mental break from the urban life.
This research arrives just as humans cross an important milestone(里程碑)．For the first time in history, the majority of people live in cities．Instead of inhabiting wide-open spaces, we're crowded into concrete jungles, surrounded by traffic and millions of strangers．In recent years, it's become clear that such unnatural surroundings have important implications for our mental and physical health, and can powerfully alter how we think.
This research is also leading some scientists to dabble(涉足) in urban design, as they look for ways to make the city less damaging to the brain．(80) The good news is that even slight alterations, such as planting more trees in the inner city or creating urban parks with a greater variety of plants, can significantly reduce the negative side effects of city life．The mind needs nature, and even a little bit can be a big help.
Which of the following is the main idea of this passage？
A．The city inspires talented people.
B．The city hurts your brain.
C．The city has many pleasures and benefits.
D．The city seriously affects the natural balance.
Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
Light and bright colors make people not only happier but also more active.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or gray.
