A group of graduates, highly established in their careers, got together to visit their old university professor. They talked about the present-day hot topic—Happiness, but conversation soon turned into complaints about stress in work and life.

    Offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and different kinds of cups-porcelain（陶瓷的）, plastic, glass, crystal, some plain looking, some expensive, some extremely beautiful—telling them to help themselves to the coffee.

    When all the students had a cup of coffee in hand, the professor said, “If you noticed, all the nice looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is normal for you to want only the best for yourselves, that is the source of your problems and stress.”

    “Be assured that the cup itself adds no quality to the coffee. In most cases it is just more expensive and in some cases even hides what we drink. What all of you really wanted was coffee, not the cup. But you consciously went for the best cups…And then you began coveting each other's cups.”

    “Now consider this: life is the coffee; the jobs, money and position in society are the cups. They are just tools to hold and contain life, and the type of cup we have does not define, nor change the quality of life we live. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has provided us. God brews（酿造）the coffee, not the cups…Enjoy your coffee! The happiest people don't have the best of everything. They just make the best of everything.”

    Live simply. Love generously. Care deeply. Speak kindly.

    Leave the rest to God.

    A six-wheeled robot travels underground in Hefei to discover warning signs of faults inside the pipeline network, "It looks like a toy car at first, but it's much more complicated than that," said Xu Mao, the robot's operator.

    The pipeline robot, developed by Wuhan Easy-Sight Technology, is made up of four parts — crawler, camera, cable reel, and controller. A full charge can enable the robot to work for four to five hours, covering a distance between 800 and 1,000 meters in the underground p ipeline.

    The robot made its appearance last month in Shushan District. It will carry out inspections of the underground pipeline network stretching 150 kilometers." Whether the pipe is leaking, damaged or blocked, we can clearly see its situation through high-definition(高清晰度的)cameras fixed into the robot, " said Qi Chuanshuai from the provincial construction engineering and testing institute.

    The real-time data including video images of the pipe will be up loaded and displayed on a computer. "If we find any problems, we stop the robot and record the flaws," Xu said. "We report the faults to local government, who will arrange the repair as soon as possible."

    With the rapid develop merit of cities, it is becoming increasingly difficult to manage underground pipelines. Among all the difficulties, discovering faults in the sewage (污水)and rainwater pipelines comes first. Many other cities such as Wuhan, Nanjing, Shenzhen, and Shanghai are using the robots to inspect their pipelines, the robot's developer said.

    Equipped with environmental detection sensors, the robots can monitor temperature and damp, poisonous gases, oxygen levels and smoke density, while providing color diagram in real time. "Compared with human workers, robots are able to enter smaller pipes and are immune (有免疫力的)to poisonous gases in sewage pipes," said Ge Shengli from Shushan District' s city management company." No digging is required and there is no need to interrupt traffic," Ge added.

    To improve Chinese on our campus, several programs will be organized. Here is some information.

Dear Mary,

How are you? I saw you posted some wonderful photos of the coastline near your hometown. You're really getting into your photography! Right now I'm taking a break to write you an email.

Remember you said you'd like to come over to the UK sometime this year? Well, I was thinking that this year you might like to come to the Edinburgh Festival with me in August. I've got an aunt with a flat in the city center who could put us up.

Do you know much about the festival? It's very famous — the biggest, most popular arts festival in the world! There are lots of things going on — art exhibitions, concerts of all kinds, modern dance, a book festival, etc. The thing it's most famous for is the newest and most exciting theatre. People come from all over the world and perform in their own languages.

In Scotland you have the best of both worlds: culture and wild land. After the festival, we could hire a car and go up to some of the islands off the west coast, like Skye. The weather can be changeable in August, but the landscape is beautiful, with empty beaches and rocky mountains. It's the perfect place for you to take photos. Afterwards, we could head back to the east coast and visit my friend Rob in St. Andrews. It's really pretty and Rob's enjoyable to be with. You'd get on well with him.

So, why don't you have a think about it and then get back to me? Take your time, there's no rush.

Speak to you soon.

Yours,

Sophie
