Lots of foreigners don’t understand why so many Chinese people are sorrowful about Yuan Longping’s passing away.

This reminds me     1     an issue more than 20 years ago,     2     I was a Chinese journalist in the US. Some American scholars     3     (think) China could hardly realize food-sufficiency because of the     4     (limit) water resources, decrease of agricultural land due to industrial     5     (expand) and the fast population growth. Just at that time, Yuan Longping announced breakthroughs in planting the new rice.     6     (bring) to large area application, this technique improved the annual growth of rice greatly, which fed     7     population of 60 million--equal to the whole of the UK.

Western scholars’ prediction of China back then was indeed analyzing China’s problems, but they failed     8     (realize) that the Chinese people have the capability to deal with these challenges.

If they had had any knowledge of Yuan who worked devotedly for our country, they wouldn’t have made such pessimistic evaluations. Why did the Chinese people make     9    ? Why are so many predictions about China in the West     10    (accurate)? It’s time to change minds to better understand China.

3 . Scientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.

The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two- dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3D in VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.

“Even though the web looks really random (随机)，there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, who presented the work on Monday at a virtual meeting of the American Chemical Society.

Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.

Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.

In 2004, the junior high school student, now 13, launched the basketball-themed Hoops of Hope,     1     “charged” people in his neighborhood $1 for every basket he shot. Since then, thousands of youngsters have picked up on the idea and raised more than $325,000 for the cause. “It works     2     kids of my age want a chance to do something great and be part of something like this,” Gutwein told China Daily.

“I realized these kids weren’t any     3     (difference) from me, except that they were suffering     4     (terrible) and I wanted to do something to help     5     (they),” he said.

    6     the help of non-government organizations, Hoops of Hope has built a school for HIV/AIDS orphans and a medical lab in Zambia in South Africa.

Another participant, Li Yeqiao, a 15-year-old student at Beijing Bayi Middle School, told the conference how the group seeks to improve the way electronic waste     7     (deal) with, and encourages people     8     (save) water and care for animals. “We have developed 3R (Reduce, Reuse and Recycle) living habits.

5 . Greying Population Stays in the Pink

Elderly people are growing healthier, happier and more independent, say American scientists.

In the last 14 years, data have been gathered on the health and lifestyles of more than 20,000 people over 65. Researchers say high blood pressure and circulation problems and other diseases of old age are troubling a smaller proportion every year.     1     . It really raises the question of what should be considered normal ageing, because the problems with old people are often not appearing until they are 70 or 75.

    2    . But there may be other contributing factors. Improvements in childhood nutrition gave today’s elderly people a better start in life.

One interesting fact is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their education live an extra seven years.     3    .

The survey also assessed how independent people over 65 were, and again found a striking trend. Their self-reliance is probably linked to an increasing use of home medical aids, such as raised toilet seats and bath seats.     4    .Those elderly people who were independent were more likely to stay healthy in old age.

    5    . Researchers found that elderly people who felt emotionally isolated maintained higher levels of stress hormones even when asleep. So they suggest that older people live best when they feel independent but know they can get help when they need it.

A．But independence can have drawbacks.

B．It is not surprising we see some effects.

C．If the trends apparent in the United States continues,

D．These developments also bring some health benefits.

E．Clearly, certain diseases can be prevented or cured because of medical advances.

F．And the rate at which these diseases are declining continues to increase.

G．Researchers say it is because educated people seek more medical attention.

6 . Facial recognition is a new technology built into all sorts of applications. It's also one of the more controversial technologies pioneered today, as it sets up deep questions regarding security versus privacy rights, and how these facial recognition applications can be safely and fairly applied.

Modern facial recognition is clearly dependent on specific technologies and algorithms (算法) that we've built during the machine learning and artificial intelligence era of the early 21st century. Specifically, most cutting-edge facial recognition programs feature a type of neural network called a convolutional (卷积) neural network (CNN). The system uses convolutions as well as other algorithm work in successive stages to do complex analysis of an image, and even identify people, animals, objects or settings through advanced analysis.

One primary piece of functionality in the CNN is feature detection. First, the face must be identified within the image context, so that the facial features can be analyzed. Methods such as the Viola-Jones are used to break down an image through color shift and local analysis of group pixels to find features like noses, ears, eyes, etc. The same facial recognition neural networks will often utilize ratios—such as the ratio from eyes to hairline, from ears to nose, or other stock facial ratios that can help with facial recognition. The image is then compared to all known faces to uniquely identify the identity of that person.

So, with all this winning technology the facial recognition engine can be surprisingly adept at learning how to recognize a particular individual’s face in a crowd. Facial recognition software is applied in payment processing to substitute cards with faces, for access and security purposes, and to identify criminals.

Primarily, companies that have used abundant public Internet images to pull together training sets for sophisticated facial recognition programs face blowback and resistance from some of their customers, including law enforcement departments, and from U.S. legislators, consumer advocates and citizens at large.

1. What are paragraphs 2 and 3 mainly about?

A．How facial recognition works technically.

B．How facial recognition is applied in society.

C．When facial recognition gets increasingly significant.

D．What the primary function of feature detection is.

2. How can facial recognition engine recognize individual’s face?

A．By comparing the image to all known faces.

B．By learning how to recognize a particular face.

C．By using convolutional neural network.

D．By identifying face within context.

3. What may be some customers’ attitude towards companies using facial recognition?

A．Positive.	B．Negative.
C．Ambiguous.	D．Indifferent.

4. From the passage, we know that ________.

A．facial recognition is a new debatable world technology

B．convolutional neural network is intended for feature detection

C．facial recognition is mostly employed to identify criminals

D．there’s still need for facial recognition to prove accuracy
