【解析】

試題分析：考查代詞和從句辨析。如果把was后的部分看作表語從句，從句缺少謂語部分，因此不是表語從句，排除A、C；空白處指代的是“那個(gè)重要的問題”，即the question of public health，為避免重復(fù)，承前省略了the question，特指用that或the one，故選D。

Scientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order. Bees are effectively solving the “traveling salesman problem”, and they are the first creatures found to do this.

The traveling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest, and it can keep computers busy for days. However, bees solve it without computer assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains, “Bees solve traveling salesman problems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum. ”

The team used the computer to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.

As well as improving our understanding of how bees move around the landscape pollinating(授粉)crops and wild flowers, this research, which is due to be published in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday networks without needing lots of computer time. Dr. Raine adds, “Despite their tiny brains, bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a computer. ”

1. What would be the best title of the passage?

A. Bees help salesmen travel

B. Tiny-brained bees solve a complex mathematical problem

C. How bees discover the flowers

D. How to solve the “traveling salesman problem”

2.We may infer from the second paragraph that the “traveling salesman problem” 　　　.

A. can be solved by a computer easily

B. can’t even be solved by a computer

C. can puzzle both people and computers

D. remains to be solved by scientists

3. The main purpose of the last paragraph is to　　　.

A. provide further proof for the research

B. tell us how bees can fly the shortest route between flowers

C. tell us how the research about bees’ flying route was conducted

D. explain the importance of the research

4. It can be concluded from the passage that　　　.

A. all creatures are smarter than computers

B. the research about bees’ flying route can be applied to many fields

C. our networks are more complex than bees’ ones

D. with the help of the computer we can find out how bees can solve the “traveling salesman problem”

Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here’s what happened. I hopped in a taxi, and we took off for Grand Central Station. We were driving in the right lane when, all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver slammed on his brakes, skidded, and missed the other car’s back end by just inches!

The driver of the other car, who almost caused a big accident, started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean he was friendly. So, I said, “Why did you just do that? This guy almost ruined your car and sent us to the hospital!” And this is when my taxi driver told me what I now call “The Law of the Garbage Truck. ”

Many people are like garbage （rubbish） trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they need a place to dump it. And if you let them, they’ll dump it on you. When someone wants to dump on you, don’t take it personally. You just smile, wave, wish them well, and move on. You’ll be happy with what you did.

I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and spread it to other people at work, at home, or on the streets? It was that day I said, “I’m not going to do anymore.”

Successful people do not let Garbage Trucks take over their day. What about you? If you let more garbage trucks pass you by, you’ll be happier. Life’s too short to wake up in the morning with regrets. So, Love the people who treat you right. Forget about the ones who don’t.

Google is testing its newest high-tech device, Google Glass. Most of the technologies for Google Glass are already available on smart phones. Google has taken those same technologies and added them to eyeglass frames（眼鏡架）. The company describes the glasses as wearable computers that would change the way people view others and the world.

"Google Glass is a tiny computer that sits in a lightweight frame, and rests neatly above your eye and it makes exploring and sharing the world around you a lot easier,” said Chris Dale, the Senior Manager of Communications for Google Glass.

The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through WIFI, a smartphone, or a tablet computer. You can make and receive calls, send and receive texts, take pictures, record video or search the web. You control Google Glass using your voice, and a touchpad on the right arm of the frame.

Professor Marcia Dawkins is among a select group of people who have been given a chance to test out Google Glass. "I thought this is something I definitely need for my classroom and hopefully for my personal life too."

The Professor's Google Glass looks like a pair bright orange glasses, without the actual glass. But there's a tiny rectangular（長方形的）glass at the top right-hand corner. Through that glass, she has been recording video while biking. She also has been able to talk to her sister in Thailand, and she plans to use the device to teach a public speaking class.

But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy.

John Simpson is the director of the privacy project at Consumer Watchdog.

"It is going to allow people to come in and spy on you and record that, without you knowing what is going on."

Filmmaker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured（捕捉）a man getting arrested after a fight. He shared the video on You Tube.

Also some are concerned about the use of facial recognition（面部識(shí)別）technology on Google Glass. But Google says it will not approve the use of such applications. The Internet company says it is still testing its new device, and it hopes to make Google Glass available to the public by early next year.

1.The technologies Google has made use of for Google Glass are______.

A.completely new

B.mostly already in use for smartphones

C.high-tech but out-of-date

D. all old

2.Which of the following is not true about Google Glass?

A. It’s a very small computer.

B. It’s very light in weight.

C. Everyone can buy it now.

D. It can be used for teaching by school teachers.

3.While cycling, the Professor has used the Glass to ______.

A.record video and chat B. send emails

C. teach a class D. spy on others

4.What can be inferred from the passage？

A.Google has done what it can to protect people’s privacy.

B.Google Glass may be used for bad purposes.

C.Most people feel worried about the use of the Glass.

D.Google Glass is more useful than smartphones.

Time flies! This is a third year that I have been in this school. In the past two and a half years, our school had organized many activities. What impressed me best was an activity called “Learning to Farm”. In an autumn afternoon, we were sent to a farm which we learned to plant potatoes. Having been in the city for so a long time, we were so happy to go to the countryside. After divided into three groups, we started to work. Some students cut potatoes into pieces; some dug holes, and the others put the pieces of potatoes into the hole, put the earth back and pushed them down hard. We continued doing that until all the work was done. Although we were exhausted, but we felt fulfilled on our way back home.
