When Susan and Steve Balog first dealt with the sudden loss of their 26-year-old daughter Emily killed in late November in an accident in Paraguay，they knew it was much too soon to ask why she was taken from them.
Even if there was an answer，in early Decembe r when Susan Balog was delivering Emily’s eulogy(颂词)，she knew that no one could understand it.
As difficult as it was，the Balogs don’t want to focus on the sadness. They try not to always think of it almost three months later. People asked then and continue to ask now: What can we do for you？To that question，the Balogs do have answers.
“Prepare a meal and share it. Make a commitment(承诺)and keep it. Look beyond yourself，〞Susan Balog explained in her eulogy. “Look beyond your sadness，your yard，your street，your belief and your country，〞she said.
“Make this place we love a better world. You are the best. You are here to help us celebrate our precious Emily and her bright light. Follow her lead to a good life.〞
Growing up in Burlington，Emily was a dedicated(有奉献精神的)Girl Scout，earning the honored Gold Award for her work teaching children art. As a member of First Reformed United Church of Christ，she learned to serve others. She served shut-ins(不能外出的人)a hot meal every Christmas through Alamance County Meals on Wheels. She helped build houses for fellow North Carolinians struck by natural disasters.
It was a speech given several years ago by Michelle Obama in Raleigh that in many ways inspired Emily’s decision to go into the Peace Corps. The special meaning of Obama’s speech was “moving out of your comfort zones〞，Susan Balog remembered.

3. In Susan’s view，the best way to remember Emily is _______.
A. not to ask them the same question any more
B. to follow her example to help others live better
C. to join the Peace Corps as Emily did in her life
D. to let her have a good rest in heaven peacefully

Imagine sitting down at your keyboard，typing in your user name and starting work right away—no password needed. That’s an idea that Darpa(the Defense Advanced Research Projects Agency)，part of the Defense Department，wants to turn into a reality. It will develop a program
that determines，just by the way you type，that you are indeed the person you say you are. Darpa’s purpose is to sponsor revolutionary research for military use. But it finally tends to find its way into the civilian(平民的)world.
Passwords like“6tFcVbNh^TfCvBn〞meet the D efense Department’s defini tion of “strong〞，says Richard Guidorizzi，a program manager at Darpa.“The problem is that they don’t meet human requirements，〞he says. “Humans aren’t built to understand random connections of characters. “No biologic sensors，like fingerprints or eye scan(扫描)，would be used. Instead，he is seeking technology that relies only on people’s unique behavioral characteristics，which he calls the “cognitive fingerprint〞.
Other experts are trying several approaches to determine users’ identities only through their computer behavior. Roy Maxion，a research professor of computer science at Carnegie Mellon University，is in charge of research on the length of time a user keeps a given key and moves from one particular key to another.
Charles C. Tappert，a professor of computer science at Pace University，has developed a program that analyzes the unique pattern of keyboard pressure；it accurately confirms the given identity of a test taker in 99.5 percent of cases，he says.
Professor Maxion has worked on another behavioral identification(身份证明):mouse dynamics(力学).He explains that everyone has a unique way of using a mouse，such as the speed with which you move the cursor(指针)across the screen；the path—straight line，or curved(弯曲的)shape.〞
1. We learn from the text that Darp a’s new program_______.
A. will stop people from using a keyboard
B. wasn’t designed for the civilian world originally
C. can make computers run faster and safer
D. helps users remember their passwords
2. In Guidorizzi’s opinion，traditional strong passwords _______.
A. fail to meet users’ requirement for safety
B. should be easy to remember
C. are more suitable for military use
D. are not convenient to use
3. Which of the following belongs to “cognitive fingerprint〞？
A. One’s scanned fingerp rints.
B. One’s facial characteristics.
C. One’s characteristics of fingers.
D. One’s way of clicking a mouse.
4. Who tries to recognize a person by his physical power of pressing a keyboard？
A. Roy Marion.
B. Richard Guidorizzi.
C. Charles C.Tappert.
D. Carnegie Mellon.
5. What’s the best title for the text？

B. The latest technology in typing
C. Go on beyond passwords
D. Which is better，keyboard or mouse？
答案与解析

III. A.语篇解读女儿的去世让父母难以承受；面对好心人的关心，母亲的答复是——像她的女儿一样，为他人和社会多做好事。

1. C 根据第一段后半句内容they knew it was much too soon to ask why she was taken from them可知，本段主要告诉我们，Balog夫妇对女儿的去世感到很突然，他们难以相信。

2. A结合第四段中Susan所说的话以及后面几段介绍Emily乐于助人的故事可知，Susan 的意思是要多为他人着想，帮助他人。

3.B根据第五段可知，Susan希望人们向她的女儿学习，去帮助他人，以此来纪念她。

4.D根据第一段可知Emily于11月下旬去世，由第三段They try not to always think of it almost three months later可推知，本文写于三个月之后，即次年二月。

5. D根据倒数第二段的earning the honored Gold Award for her work teaching children art可知，Emily曾教过孩子们美术，并获过奖。

B.语篇解读简单的密码不平安，可复杂的密码又难记。

一种新技术有望使人们摆脱这种困扰，使上网登录变得轻松自如。

1. B 根据第一段后两句Darpa’s purpose is to sponsor revolutionary research f or military use. But it finally tends to find its way into the civilian world可知，答案是B。

2.D 根据第二段Guidorizzi的话The problem is that they don’t meet human requirements…Humans aren’t built to understand random connections of characters可知，他认为传统的密码复杂难记，不符合人们的认知规律，使用不便。

3.D 根据第二段可知，cognitive fingerprint不使用biologic sensors验证使用者的生物特征，而是验证其独特的行为特征(behavioral characteristics)，可推知D选项“点击鼠标〞的方式属于此类。

4.C 根据倒数第二段的Charles C. Tappert… has developed a program that analyzes the unique pattern of keyboard pressure可知，Tappert教授通过研究敲击键盘的力度来验证使用者的身份。

5.C 全文主要介绍的是摆脱传统密码，方便人们轻松登录的新技术，应选C。
