With the development of economy, how to balance progress and the protection of cultural heritage 【小题1】(be) a big challenge we are facing. Great solutions, however, tend to arise from the challenges.

In the 1950s, in order to control the flooding and to get electricity from the flow of the Nile River, the Egyptian government made【小题2】proposal to build a new dam across the Nile. It would cause the water levels to rise high enough【小题3】(flood) a number of ancient temples,【小题4】were among Egypt’s cultural heritage. So the government turned to the United Nations【小题5】help.

Soon, an international committee【小题6】(establish) to help Egypt to find the solution. Finally, they made a decision that all cultural relics should be removed. With the unprecedented (前所未有的), international effort, the government【小题7】(successful) moved the temples and other cultural sites to a new【小题8】( locate ) on higher ground .

The project was considered a greatly successful example by UNESCO to prevent world heritage from   【小题9】(disappear). More importantly, the success shows that if a problem seems too difficult for a single nation, the global community can make a big【小题10】(different). The fact proves it is possible for countries to work together to build a better future.

My family have been involved in agriculture business since the late 1800s when my great-grandfather 【小题1】 (start) the family farm. Over the years, the operation has developed from growing crops into selling farm equipment today — our primary focus has become the technology used in farming.

Agriculture, 【小题2】 general, has undergone a similar 【小题3】 (develop). Technology has become an indispensable part of doing business for every farmer, and agriculture retailer. In fact, a recent study by Hexa Reports suggests precision agriculture 【小题4】 (expect) to grow to $ 43.4 billion by 2025. It is a concept that was born in the 1990s and that was quite 【小题5】 (impress).

The increasing adoption rate of technology in agriculture shouldn’t be 【小题6】 (surprise) to anyone. Farming is 【小题7】 (high) land-intensive and labor-intensive. Farmers are driven to use technology to increase efficiency and manage costs.

But what exactly does the precision agriculture mean? Precision agriculture is also known as precision farming. Perhaps the easiest way 【小题8】 (understand) precision farming is to think of it as everything 【小题9】 makes the practice of farming more accurate and controlled when it comes to the growing of crops. A key component of this farm management approach is 【小题10】 use of information technology and a wide range of items such as sensors, drones, and GPS-based soil sampling.

Honoring teachers and their intelligence has always been a tradition in China. Since ancient times, teachers 【小题1】(respect) as messengers of wisdom. The famous Chinese idiom, “Cheng Men Li Xue”, which 【小题2】(literal) means “standing in the snow at the gate of Cheng’s home”, is a wonderful example.

“Cheng” refers to Cheng Yi, a leading 【小题3】 (educate) of Neo-Confucianism in the Song Dynasty. Attracted by Cheng’s theory, Yang Shi, a talented and hardworking young man, worshiped Cheng as his mentor.

One day, Yang and his friend had different opinions on one question and went to Cheng’s home for advice. It was in the middle of winter. Feeling 【小题4】 (freeze) by the wind and snow, the two men wrapped 【小题5】 (they) tightly in their clothes and hurried on. When they arrived at Cheng’s place, the gatekeeper said the master 【小题6】(take) a nap.

The two students did not complain. Instead, they chose not 【小题7】 (disturb) the teacher and waited outside the door, standing in heavy snowfall.

After quite some time, Cheng, upon waking up, became aware 【小题8】 his students had been standing in the snow for a while 【小题9】 immediately invited them to come in. Deeply moved by their patience, Cheng gave detailed answers 【小题10】 the students’ questions. After years of study, Yang finally achieved his life goal as a great scholar.
