100 years ago, The Communist Party of China (中国共产党) was born on the Nanhu ship. After many     1     (year) of hard struggle, the Communist Party of China finally won     2     victory of the revolution and     3     (found) The People’s Republic of China in 1949, Chairman Mao wrote     4     (excited): The fate of the Chinese people     5     (be) in their own hands, China will rise in the east like the sun.

Under the leadership of the Communist Party of China, the people of all ethnic groups     6     (overcome) difficulties and made a series     7     great achievements. In the days to come, every Chinese should be full of confidence in     8     (move) towards a better future. With more     9     (confident), diligence and     10     (strength) spirit, we express our loyalty and persistence to the party and the country.

What will our cities be like in 2050? How much will artificial intelligence advance? Some scientists    1     (make) different predictions recently.

Joel E.Cohen from the The Rockfeller University says    2    is likely that by 2050 the majority of the people in the world will live in urban areas, and will have a    3    (significant) higher average age than people today. Cities will be    4    only realistic solution to housing a population that is expected to expand    5    9.7 billion by 2050.

And the technology will keep    6    (advance) rapidly. According to Bill Michell, the late director of MIT Media Lab’s Smart Cities research group, cities of the future won’t look like “some sort of science-fiction fantasy” or “Star Trek” ,but virtual reality will change    7    we live. Self-driving cars will make the roads    8    (secure), driving more efficient, and provide faster transport.

Charles Ebinger at the Brookings Institution thinks that by 2050 we will also have a so-called “smart grid” where all of our    9     (appliance) are linked directly to energy distribution(分布) systems,    10    (allow) for real-time pricing based on supply and demand. Such a technology would greatly benefit most people and reduced the consumption(消耗) of fossil fuel energy.

Although it is cold outside in winter, we have heating systems to keep us warm indoors in most parts of North China and in South China, they at least have air conditioners or electric radiators. But how did ancient people    1    China keep warm without modern equipment?

During the Qin and Han dynasties, temperature adjustable rooms    2     (appear) in royal families. Royal courts had    3     (large) and more advanced rooms, called the “temperature adjustable halls”. And    4     (palace) such as Changle Palace in Weiyang Palace in Western Han dynasty had temperature adjustable halls. Changle Palace, which was    5     (original) used as the government's “office building” and “president suite” for Liu Bang, not only had heating room for winter but also rooms for     6     (cool) down in summer.

A comfortable temperature could help preserve books,     7    made these halls were good places to store books and provide a better environment for reading.

    8    is said that the “temperature adjustable hall” was built with the wall which    9     (cover) with prickly-ash mash (花椒泥). Tapestries (挂毯) on the wall, a thick blanket on the ground and wild goose feather-made curtains were also used    10     (keep) cool air outside.

My grandfather is a Party member. He often shares stories about the Communist Party of China     1     me. One day, he talked about his fight in the Anti-Japanese War. He admitted that he had been afraid, but his determination to defend the country helped him overcome his fear. I thought my grandfather was a hero. He often reminds me that our     2     (peace) and happy life today is because of revolutionary martyrs (烈士). Our generation should be grateful to our great Party.     3     (inspire) by these stories, I make up my mind to study hard and make our country more powerful.

Once regarded as a geographical disadvantage, Shantang village in Zhejiang province has now become an     1     (attract) tourism destination. It     2     (locate)in the northeastern tip of Guangchen town. It was off the beaten track when the road was not in good condition. However, with transportation improved, the village is connected to Shanghai by a stone bridge     3     a river.

Tourists can enjoy     4     (they) by walking among trees and grasslands, taking in the view of the lake and getting a look at the past through old items such as     5     (sew) machines, radios and photos which are preserved in a museum converted (改造) from an old house. Buses connecting the village to neighboring provinces are up and running in     6     endless stream. Over the past few years, dragon boat competitions and local festivals have been     7     (regular) held to enrich visitor experience. Local authorities have also restored a street     8     dates back to the Qing Dynasty to promote rural tourism in the village.

Shantang now offers sightseeing, leisure and shopping     9     (activity). Favorable policies have been introduced to encourage locals     10     (set) up shops on the streets. Last year, the historical street had 400,000 tourist visits, earning more than 20 million yuan in tourism income.

People have lived in cities for thousands of years. Yet even just 100 years ago, more people     1     (live) in the country than in cities. Today, with the population in the world     2     (increase) sharply, more people move to cities for various     3     (reason). For many it is for work or education. Some are     4     (simple) attracted to city life. By the year 2030, it is thought     5     more than sixty percent of the world's population will be living in cities. More and more cities will become megacities (特大城市), and they will     6     (find) in different parts of the world.

Maybe one megacity is not the same as another     7     they do have common problems, such as air     8     (pollute), housing problems, traffic jams and so on. Making these cities work well for every person living in them will be     9     great challenge in the future. However, we do believe when people work together, they can find solutions which will help make these megacities happy, healthy and     10     (excite) places to live in.

Robotic age draws closer

These days, robots are     1     (common) than you might think. Consider the Roomba,     2     robotic vacuum cleaner (真空吸尘器) which cleans floors on its own.

“We wanted to make something simple     3     people could use every day,” says Greiner, co-founder of iRobot, the company that makes the smart vacuum cleaner.“And that's what inspired us to build the Roomba.”

Some robots like the Roomba are already very common in many US households.

iRobot makes everything from the Roomba to robots that someday might become a part of us.

“You can have robotics     4     (equip) into your body, to get back that arm or leg that you've lost, either in some accident or disease,”says Greiner.

Although robots have been developed mainly for military     5     (apply), civilian uses for the technology are growing, according to Michael Toscano, president of the Association for Unmanned(自控的) Vehicle Systems International.

Unmanned systems allow human beings to do their tasks     6     an extension of their hands, their eyes and their ears,”

“We can put them in the ocean and they     7     (swim) for eight or nine months, collecting data and monitoring ocean pollution,”says Hudson of iRobot.

Recently the US government's Defence Advanced Research Projects Agency (DARPA) displayed a“robotic man”.

Instead of depending on the remote control, DARPA's “robotic man”can     8     (actual) look at some blocks, find one with a special pattern, and move it to a new location. Mandelbaum, DARPA's project manager, says more     9     (challenge) tasks lie ahead.

Someday, a DARPA robot might find a hidden bomb or help a disabled person select a shirt and button     10    .
