新课标2015年高二英语暑假作业10 （满分100分） 第二部分阅读理解（共两节，满分30分） 第一节（共4小题；每小题5分，满分20分） 阅读下列短文，从每题所给的四个选项（A、B、C、和D）中，选出最佳选项，并在答题 卡上将该项涂黑。 For some reason we were reminded that we primates(灵长目) need love. Kim Bard of the University of Portsmouth in England and her colleagues carried out a study on 46 baby chimpanzees orphans(黑猩猩孤儿), which had lost their mothers. The study showed that primate babies that have tight relationships with mother figures do much better on cognitive (认知的 ) tests than babies who only grew up with peers (同伴), but this is not breaking news. In fact, it ' s old news. In the 1950s, Harry Harlow did a series of experiments with baby monkeys that showed. that lack of love and comfort makes for a crazy monkey. Harlow constructed a cage that included a wire monkey "mother" with a plastic face. Then he equipped the "mother" with a milk bottle .The cage also had another wire "mother" who was covered with soft cloth. The baby monkeys spent all their time with the cloth "mother" arid only went to the wire "mother" to feed. Harlow's monkey experiment was important because, at the time, child care experts, and everybody's grandmother had a "no touch, no comfort" policy toward children. They advised parents not to respond to crying babies. They thought that babies should sleep alone to become independent, and for God's sake put that kid down. But Harlow's work changed that policy. Mothers were soon permitted to have their babies next to them in the hospital. The current chimp research based on Harlow's work shows that mother's love doesn't just make for a psychologically(糖神上地) healthy child, it also makes for a smart child. The highly raised chimps do better than those that are not loved, and the well-raised chimps do even better than human kids on IQ tests. We are primates, social animals which need love. We need to be held and talked to and made to feel that at least one person wants to be with us all the time. 1. The study Kim Bard and his colleagues did A. included 46 baby and mother monkeys B. is nothing new to people about the findings C. showed that many chimpanzees lack of love when they were young D. showed many chimpanzees had good relationship with their mothers 2. Harlow built two "mothers" for baby,.monkeys to _______ A. make them live comfortably B. let them have more choices

It was Thursday, and like every Thursday, I was exhausted end just sick of everyone and everything. “Mommy?" asked my older daughter. " What?” I practically shouted. Could' t they just eat without demanding anything? " It seems that the spaghetti is overcooked," she said. I glanced at my husband, and he just gave a slight nod in agreement with ray daughter. Why could’ t I even cook something simple as spaghetti? Then I remembered why. Because every time I was trying to gel dinner cooked, I could be distracted (分心）by so many other things. I hung my head in defeat once again. Sometimes, I just wanted to cry. Throughout my journey in motherhood, 1 have concluded that my abilities are an absolute failure at times. This spaghetti dinner was just another example. I don' t even know how to balance the “wife” with the “mother” anymore. Romance is a distant memory. My only goal as a mother is to survive, because not burning down ray house or losing a kid would be an accomplishment.. “ It's s okay, honey, ” my husband said as He patted me on the back, “I" see if we have a frozen pizza or something. " I nodded. I knew we would laugh at this later, but it was just another moment of failure.

matlab实现功率谱密度分析psd及详细解说 功率谱密度幅值的具体含义？？ 求信号功率谱时候用下面的不同方法，功率谱密度的幅值大小相差很大！ 我的问题是，计算具体信号时，到底应该以什么准则决定该选用什么方法啊？ 功率谱密度的幅植的具体意义是什么？？下面是一些不同方法计算同一信号的matlab 程序！欢迎大家给点建议！ 直接法： 直接法又称周期图法，它是把随机序列x(n)的N个观测数据视为一能量有限的序列，直接计算x(n)的离散傅立叶变换，得X(k)，然后再取其幅值的平方，并除以N，作为序列x(n)真实功率谱的估计。 Matlab代码示例： clear; Fs=1000; %采样频率 n=0:1/Fs:1; %产生含有噪声的序列 xn=cos(2*pi*40*n)+3*cos(2*pi*100*n)+randn(size(n)); window=boxcar(length(xn)); %矩形窗 nfft=1024; [Pxx,f]=periodogram(xn,window,nfft,Fs); %直接法 plot(f,10*log10(Pxx)); 间接法： 间接法先由序列x(n)估计出自相关函数R(n)，然后对R(n)进行傅立叶变换，便得到x(n)的功率谱估计。 Matlab代码示例： clear; Fs=1000; %采样频率 n=0:1/Fs:1; %产生含有噪声的序列 xn=cos(2*pi*40*n)+3*cos(2*pi*100*n)+randn(size(n)); nfft=1024; cxn=xcorr(xn,'unbiased'); %计算序列的自相关函数 CXk=fft(cxn,nfft); Pxx=abs(CXk);
