Please mark the corresponding letter for each them on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

Questions 47 to 56 are based on the following passage,

One in six. Believe it or not, that’s the number of Americans who struggle with hanger To make tomorrow a little better, Feeding Action Month. As part of its 30 Ways in 30 Days program, It’s asking 48 across the country to help the more than 200 food banks and 61,000 agencies in its network provide low-income individuals and families with the fuel they need to 49 .

It’s the kind of work that’s done every day at St. Andrew’s Episcopal Church in San Antonio, People who 50 at its front door on the first and third

Thursdays of each month aren’t looking for

In the wake of the 53 .the number of families in need of food assistance began to grow. It is 54 that 49 million Americans are unsure of where they will find their next meal What’s most surprising is that 36% of them live in 55 where at least one adult is working.“It used to be that one job was all you needed.” says St. Andrew’s Drane.“The people we see now have three or four part-time jobs and they’re still right on the edge 56 .”

Answer Sheer 2 with a single line through the centre.

Passage One

Questions 57 to 61 are based on the following passage.

In times of economic crisis, Americans turn to their families for support. If the Great Depression is any guide, we may see a drop in our skyhigh divorce rate. But th is won’t necessarily represent an increase in happy marriages. In the long run, the Depression weakened American families, and the current crisis will probably do the same.

We tend to think of the Depression as a time when families pulled together to survive huge job losses. By 1932, when nearly one-quarter of the workforce was unemployed, the divorce rate had declined by around 25% from 1929. But this doesn’t mean people were suddenly happier with their

marriages. Rather, with incomes decreasing and insecure jobs, unhappy couples often couldn’t afford to divorce. They feared neither spouse could manage alone.

Today, given the job losses of the past year, fewer unhappy couples will risk starting separate households, Furthermore, the housing market melt down will make it more difficult for them to finance their separations by selling their homes.

After financial disasters family members also tend to do whatever they can to help each other and their communities. A 1940 book The Unemployed Man and His Family described a family in which the husband initially r eacted to losing his job “with tireless search for wor k.” He was always active, looking for odd jobs to do.

The problem is that such an impulse is hard to sustain across the country. Many similar families were unable to maintain the initial boost in morale(士气). For some, the hardships of life without steady work eventually overwhelmed their attempts to keep their families together. The divorce rate rose again during the rest of the decade as the recovery took hold.

Millions of American families may now be in the initial stage of their responses to the current crisis, working together and supporting one another through the early months of unemployment.

Today’s economic crisis could well generate a similar number of couples whose relationships have been irreparably(无法弥补地)ruined. So it’s only when the economy is healthy again that we’ll begin

to see just how many broken families have been created.

D)Money is the foundation of many a happy marriage

Passage Two

Questions 62 to 66 are based on the following passage:

People are being lured (引诱)onto Facebook with the promise of a fun, free service without realiz ing they’re paying for it by giving up loads of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Face book because people don’t really know what their personal data is worth.

The biggest problem, however, is that the company keeps changing the rules. Early on you keep everything private. That was the great thing about facebook. You could create own little private network. Last year. The company changed its privacy rules so that many things your city, your photo, your friends’ names-were set, by default (默认)to be shared with every one on the Internet.

According to Facebook’s vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information . They have a “less satisfying experience”.

Some critics think this is more about Facebook looking to make more money than to improve its service. In original business model, which involved selling ads and putting them at the side of the pages totally. Who wants to l ook at ads when they’re online connecting with their friends?

The privacy issue has already landed Facebook in hot water in Washington. In April. Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and

how people could choose to use them or not to use them,” Schrage admits.

I suspect that whatever Facebook has done so far to invade our pri vacy, it’s only t he beginning

w hich is why I’m considering deactivating(撤销)my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t trust. That’s too high a price to pay.

A)It is a website that sends messages to targeted users.

B)It makes money by putting on advertisements.

C)It profits by selling its users’ personal data.

D)It provides loads of information to its users.

63.What does the author say about most Facebook users?

A)They are reluctant to give up their personal information.

B)They don’t know their personal data enriches Facebook.

C)They don’t identify themselves when using the website.

【目的】 (1) 掌握IIR 和FIR 数字滤波器的设计和应用； (2) 掌握多速率信号处理中的基本概念和方法 ； (3) 学会用Matlab 计算小波分解和重建。 (4)了解小波压缩和去噪的基本原理和方法。 【研讨题目】 一、 (1)播放音频信号 yourn.wav ，确定信号的抽样频率，计算信号的频谱，确定噪声信号的频率范围； (2)设计IIR 数字滤波器，滤除音频信号中的噪声。通过实验研究s P ,ΩΩ，s P ,A A 的选择对滤波效果及滤波器阶数的影响，给出滤波器指标选择的基本原则，确定你认为最合适的滤波器指标。 （3）设计FIR 数字滤波器，滤除音频信号中的噪声。与（2）中的IIR 数字滤波器，从滤波效果、幅度响应、相位响应、滤波器阶数等方面进行比较。 【设计步骤】 【仿真结果】

【结果分析】 由频谱知噪声频率大于3800Hz。FIR和IIR都可以实现滤波，但从听觉上讲，人对于听觉不如对图像（视觉）明感，没必要要求线性相位，因此，综合来看选IIR滤波器好一点，因为在同等要求下，IIR滤波器阶数可以做的很低而FIR滤波器阶数太高，自身线性相位的良好特性在此处用处不大。【自主学习内容】 MATLAB滤波器设计 【阅读文献】 老师课件，教材 【发现问题】(专题研讨或相关知识点学习中发现的问题)： 过渡带的宽度会影响滤波器阶数N 【问题探究】 通过实验，但过渡带越宽时，N越小，滤波器阶数越低，过渡带越窄反之。这与理论相符合。 【仿真程序】 信号初步处理部分： [x1,Fs,bits] = wavread('yourn.wav'); sound(x1,Fs); y1=fft(x1,1024); f=Fs*(0:511)/1024; figure(1) plot(x1) title('原始语音信号时域图谱'); xlabel('time n'); ylabel('magnitude n'); figure(2) freqz(x1) title('频率响应图') figure(3) subplot(2,1,1); plot(abs(y1(1:512))) title('原始语音信号FFT频谱') subplot(2,1,2); plot(f,abs(y1(1:512))); title(‘原始语音信号频谱') xlabel('Hz'); ylabel('magnitude'); IIR： fp=2500;fs=3500; wp = 2*pi*fp/FS; ws = 2*pi*fs/FS; Rp=1; Rs=15;

You should write at least 120 words but no more than180 words. 【参考范文】 On June 14, Friday, a volunteer activity where many students took an active part in visiting the local Nursing House was organized by the Student Union and it turns out to be a big success. The activity was aimed at encouraging students to visit the elderly at the Nursing House and help elderly people deal with their troubles both physical and psychological. Many students volunteered to participate in this good deed and were engaged in helping the elderly here out by making their meals, washing their clothes and chatting with them. When asked about those volunteers’feelings about such an experience, all of them responded with a smile, saying “what a wonderful practice and I really appreciate this experience, for it makes me learn to care more for others in need.” All in all, the activity turns out to be a success not only for the visited elderly but for those students involved. 【参考范文译文】 6月14日，星期五，学生会组织了一个参观当地敬老院的志愿活动，许多学生都积极参与其中，该活动取得了巨大的成功。 此次志愿活动旨在拜访当地敬老院的老人们并对他们各个方面的困难提供帮助。许多学生主动加入到此次善举当中，帮老人们洗衣做饭、谈心解闷，竭尽所能提供帮助。问及参与此次活动的感想时，他们毫无例外地回道“真是太有意义了，很感谢这次经历，它让我懂得要去更加关爱那些有困难的人” 总而言之，此次活动取得了巨大成功，不仅仅对那些老人来说受益多多，对于参与的学生来说也是意义良多。 Part III Reading Comprehension (40 minutes)Section A The center of American automobile innovation has in the past decade moved 2,000 miles away.
