Sony Notebook’s questionnaire
Name: Excellence Good Average Fair Poor
1. you think Sony notebook is
2. you think the price of the Sony notebook is
3. you think market development tendency is
4. you think the Sony notebook's post-sale service's appraisal are:
5.you think the Sony brand influence is
6.you think the battery lasting ability is
7.you think the outward appearance design is
8. you think sales personnel’s' vocational level is
9.you think the quality of the Sony notebook is
10.you think the its sharpcloud is
What I do is about Sony notebook’s questionnaire. At Present notebook is very popular, nearly all participants have expressed that they are using a notebooks. The import brand seems more popular than domestically produced brand. Most respondents have said they pay more attention to import brand's high quality and durability when buying notebooks. Of course, most of the import notebooks are big brand is part of the reason.
I investigate users of a series of questions about Sony notebook such as the price, its market development prospect, the post-sale service, the brand effect, the battery endurance, the design style; the staff sells ability, the quality and the disposition.
According to the investigation, almost 80% students are satisfied with the Sony notebook in the world's prospects for development, and the notebook performance, the grade of service, but 90% of the students can't accept the price. In my opinion, although its factory is taken to China, there have been little manifestations in the price; the price is still very expensive. Especially since 2004, Sony personal computer in Japan experienced large scale loss. Therefore the price adjustment and indepth knowledge of Chinese market's still require improvement. 90% people agree the Sony brand has brilliant influence all over the world. But 70% people think the battery doesn’t last long enough. 50% people are attracted by the changeable style. Almost all the people take fancy to the reliable quality. 80% of the staff sales personnel’ vocational level should be improved .30% students are not know much about the sharpcloud and not pay much attention to it. In total, I think it’s a reliable brand.

不妨设总成本函数TC=F(Q) MC=F'(Q) AC=F(Q)/Q
当MC>AC 有 F'(Q)-F(Q)/Q>0

表4也显示了柱状颗粒平均宽度(数据),(这些宽度)仅在双氛保护的平面定位焊接沉淀中(才能)测定得到,是由于在上位焊接中非常少量的“PF(G)”造成的.如同以前的发现(参考文献10,11,21-23),可以发现作为前体物的晶界铁素体的尺寸是随着输入热量的增加而增加的.
推论
1,only强调的是deposits就是沉淀中.
2,由于严重缺乏上下文,我不能推测“PF(G)”的意思.
3,可能是在焊接中,需要N2等保护不受氧化,在焊接的熔渣中发现了柱状颗粒.

People who averaged fewer than seven hours of sleep per nigh
People who averaged fewer than seven hours of sleep per night in the weeks before being exposed to the cold virus were nearly three times as likely to get sick as those who averaged eight hours or more, a new study found.
Researchers used frequent telephone interviews to track the sleep habits of more than 150 men and women aged 21 to 55 over the last few weeks. Then they exposed the subjects to the virus, quarantined (检疫隔离) them for five days and kept track of who got sick.
Besides sleeping more, sleeping better also seemed to help the body fight illness: Patients who fared better on a measure known as “sleep efficiency”—the percentage of time in bed that you’re actually sleeping—were also less likely to get sick.
The results held true even after researchers adjusted for elements such as body-mass index, age, sex, smoking and pre-existing antibodies (抗体) to the virus.
The researchers aren’t exactly sure why sleeping better makes you less likely to develop a cold. But they do try to give an answer: “Sleep disturbance influences the regulation of symptom mediators (调节因子) that are released in response to infection.” In plain English, maybe tossing and turning when you’re infected with the cold virus contributes to the symptoms that define a cold.
The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.
小题1: According to the passage, what does the underlined word “subjects” mean in paragraph 2?
A.areas of knowledge in a school
B.people being studied in an experiment
C.research topics
D.animals being tested
小题2:It is shown in the passage that _______.
A.the researchers obtain information about the sleep habits by frequent interviews
B.the researchers do their research in the National Institutes of Health
C.people hope to avoid being infected with a cold by sleeping as much as possible
D.sleeping more and better helps regulate the symptom mediators
小题3:What’s the best title of the passage?
A.The Relationship Between Virus and Cold
B.How to Sleep Well
C.Good Sleep Helps Fight a Cold
D.The More the Sleep, the Better Your Body
