Our school, Chairo Technical School in Australia, has a strong service idea that covers two of     1    (we) core values, namely “life-long learning” and “life-long serving”. All the students are encouraged to become     2    (active) involved in these programs and many opportunities exist at all the     3    (level) through the country.

Teams of teachers and students from the school     4    (send) to every part across the whole country and other countries regularly to participate     5     different programs, including a regular English teaching tour of our sister school in China. As a school we are always seeking different service opportunities,     6     will encourage our students to devote their time and efforts to     7    (assist) those more needy than themselves.

As     8     matter of fact, many programs     9    (aim) at helping the needy and elderly within our local communities also occur throughout each year, including an annual activity, Service Week. While these programs do assist those in need, it is also exciting to see the    10    (person) growth that occurs among our participating students. The real-life experiences strengthen our teamwork effectively in order to better serve the society for life.

Have you ever wondered what life is like in a smart city? Well, when you go to a certain shopping mall now, you can enjoy     1    (it) free Wi-Fi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen     2     the basic parts of a smart city.

The idea of a smart city     3    (bring) up by the US company IBM in 2010. Generally, a mart city is a city     4     uses digital technologies such as the Internet to improve the     5    (manage) of the city, save money and resources, and make our life     6    (easy) and more convenient.

In 2009, Dubuque became the first smart city in the US.     7    (use) a smart system, people were able to make better use of their resources, like water, electricity and     8    (nature) gas. This way, they helped reduce waste.

Santander in Spain also gives us     9     look at the future. The government provides an app that collects data on almost everything: light, temperature, and the movements of cars and people. Open the app near a supermarket,     10     you’ll find immediate information on special offers.

Acupuncture, one of the most famous Chinese medical treatments, is increasingly well received among the world with solid evidence    1    it has a certain edge over western medicine.

    2    (date) back to the Stone Age, the magic needles    3    (measure) between 15 and 75 millimeters in length played a critical role in treating patients in the old past of China and over time, these needles     4    (change) in materials and shapes. While examining a patient, the acupuncturist looks at the patient’s skin and tongue, listening to the sound, smelling his breath, asking about his condition and feeling his pulse. According to    5    results of the check-up, the acupuncturist selects certain points on the body called acupuncture points. So far, more than 360 acupuncture points have been identified, each of     6    linked to a different part of the body. However,    7    acupuncture actually works is not clearly understood, and no agreement has been reached. But anyway, there really existed such a phenomenon    8    patients can restore health after being treated by the acupuncture, so    9    the uncertainty about its medical basis, these years it has been applied to treat a wide range of health problems and is preferred at home and abroad. In 2010, acupuncture was included in the UNESCO ICH. Today, it is recognized     10    a symbol of TCM and has come into widespread use.

A memorial service     1     (bid) farewell to “father of hybrid rice” Yuan Longping     2     (hold) in Changsha, Central China’s Hunan province on Monday.

Despite it     3    (be) a busy work day, thousands of people wearing black came to the Mingyangshan Mortuary House in the city,     4    the memorial service was held at 10 am, to present bouquets (花束) and bunches of rice and pay tribute (颂词) to Yuan.

The top rice scientist, who developed the first high-yield hybrid rice strain in 1973, died of organ     5     (fail) at age 91 on Saturday.

The agronomist (农学家) spent over five decades     6    (research) and improving hybrid rice, which has reached its third generation, helping China work     7    great wonder— feeding nearly one-fifth of the world’s population with less than 9 percent of the world’s total arable (适合耕种的) land.

People from all walks of life in China and abroad expressed their condolences after Yuan’s death, which indicated that his contribution to the hybrid rice industry has been     8    (wide) recognized and highly praised, Zhao Lijian, spokesman of the Ministry of Foreign Affairs, said at a news conference in Beijing on Monday.

“His death is a great loss to China and the world, and he     9    (remember) by people” , Zhao said.

He added that academician Yuan not only belongs to China, but also to the world. His lifelong dream was to see hybrid rice to be planted around the world,     10    no one will be left hungry.

Chinese scientists have created starch(淀粉) using carbon dioxide, hydrogen and electricity, according to a study     1     was published in the journal Science on Sept 24.

It's the first time in the world that synthesis(合成) of starch from CO₂     2     (achieve). Scientists believe it will have a     3     (revolution) impact on future agricultural production and bio-manufacturing.

According to Ma Yanhe,     4     author of the study, the process of plants     5     (create) carbohydrates like starch through photosynthesis(光合作用)is complex and     6     (efficient). It takes a plant about 60 steps of metabolic(新陈代谢的) reactions to turn CO₂, water and sunlight into starch. But now Chinese scientists have simplified the process from 60 steps into 11.

Creating carbohydrates more efficiently is so important for     7     (sustainable) on Earth, noted ChinaDaily. If such an approach can be scaled up(扩展) to the level of industrialization, it     8     (save) more than 90 percent of the farm land and freshwater resources, and avoid negative effects on the environment     9     pesticides and chemical fertilizers(肥料), and it will improve food     10     (secure) and promote sustainable societies, according to Cai Tao, another author of the study.

Willis Carrier     1     (design) the first air-conditioning unit in 1902, just a year after     2     (earn) his master's degree in engineering from Cornell University. At a Brooklyn printing plant, changes in heat and humidity (湿度) were causing the size of the printing paper to keep changing slightly, making     3     hard to arrange different colours. With Carrier's invention, temperature and humidity levels could     4     (control), so the problem was solved. The invention also allowed industries such as those of film, processed food, and textiles     5     (improve) the quality of their products.

In 1914, the first air conditioner was put in a private house. However, it took up too much space, and later models cost too much for most people. Cooling for human comfort, rather than industrial needs,     6     (actual) took off when three air conditioners were set up in the J.L. Hudson Department Store in Detroit, Michigan. People crowded into the shop to experience the new invention. The fashion spread from department stores to cinemas, whose income rose steeply (急剧地) as a result     7     the comfort they provided. According to research     8     (conduct) in the 1950s, air conditioning increased productivity amongst     9     (employee).

Jed Brown,     10     is an environmentalist, complains that air conditioning is a cause of global warming. However, he has to admit that it provides a healthier environment for many people in the heat of summer.
