These days, people are trying to live in a “green” way. Advocates of living in greener 【小题1】 (community) think it is not a good idea to delay 【小题2】 (solve) environmental problems. They say we can use ideas and technologies available 【小题3】 (create) the city of the future today.

For example, in the green city of the future, modern buildings 【小题4】 (design) to save water and energy. Outdated buildings of the past were not. Rooftops covered with grass and other living plants provide insulation (隔热材料) 【小题5】 keeps buildings cooler. These roofs can also collect and reuse rainwater that would otherwise be wasted.

Besides, citizens of the green city understand that protecting native species 【小题6】 (be) the key to protecting natural spaces. Because native plants are original to the ecosystem, they provide the best habitats 【小题7】 local insects, birds and other animals. Native plants can also 【小题8】 (well) adapt to the local climate and require less water.

Residents also recognize that a process called composting (堆肥) helps reduce 【小题9】 amount of solid waste and increase the richness of local soil. People first mix food waste with water and air in large bins. Then 【小题10】 (help) bacteria break down this pile of “garbage” into an eco-friendly and economical fertilizer.

China's first manned spaceship lifted off at 9 a. m. on Wednesday, October 15th, 2003 in Jiuquan, Gansu Province. It carried China's first astronaut, Yang Liwei,【小题1】was a pilot in the army. The launch was【小题2】（success）. "When the spaceship separated【小题3】the rocket, I suddenly got【小题4】feeling of soaring into the sky because of the zero gravity, "said Yang Liwei. The Shenzhou V circled the earth 14 times. When the spaceship【小题5】（do）its seventh circle, Yang showed the flags of China and the United Nations,【小题6】（express）the wishes of the Chinese people【小题7】（explore）and use space【小题8】（peaceful）.

Millions of people all over China were watching TV when the spaceship landed safely. Yang was happy to return home【小题10】he thought 21 hours was too short to stay in space.

We send words, pictures or videos 【小题1】 our friends on the Internet every day. But 【小题2】 seems that we can also even send them a glass of lemonade now.

This is 【小题3】 the unimaginable technology works. First, a color sensor (传感器) and a PH sensor 【小题4】 (place) in a real glass of lemonade. Then a control module sends information about the color and taste of the lemonade to a special glass 【小题5】 (fill) with water at another 【小题6】 (locate). By 【小题7】 (use) electronic stimulators (刺激物), the special glass recreates the taste of the original when the recipient (接受者) drinks the water. Researchers found that there are no significant 【小题8】 (different) between a real glass of lemonade and a virtual (虚拟的) one.

If the technology is improved, we may even soon be able to share our 【小题9】 (favor) dishes with our friends online instead of in simply 【小题10】 photo.
