Technology and sustainability(可持续性) are two driving forces in the world today. For the agriculture department, sustainable agriculture technology must be the new trend, and farmers should follow it.

The following sustainable agriculture technologies are necessary.

Smart irrigation

Crops need water—that's needless to say. However, how they get water is another story.

With smart irrigation technology, water can be put to good use. New irrigation systems with smart technology can report soil moisture(湿度) and temperature in real time. These new technologies help farmers properly take care of crops in a more efficient way. For example, most crops have specific requirements for temperature and moisture. The new irrigation systems can show farmers whether they need to make changes for their crops' growing environments. In this way, they may help reduce the waste of water.

Drones

Drones' abilities get them a place on this list. They can do a lot and most importantly, they can make the boring and tiring farm work much easier.

These devices have high-definition cameras that take pictures and videos. Through wireless control, just at home farmers can fly the drones over the fields and check on crops. If one area of crops isn't doing well, farmers can quickly record the details and then spray chemicals with the help of the drones.

Data and software

Data is rich in this tech-driven world. Farming and data working together can greatly change the way farmers plant, harvest and water.

As computers gather information, they report it all back to a central system. So when farmers learn in which area crop health needs to improve, they can use water and fertilizer(肥料) more efficiently, causing less waste.

The three technologies are helpful for farmers to save costs, labor and energy. And they can contribute to the final goal of agricultural sustainability—that is to improve the environment. As these new technologies continue to develop, we are sure to have a cleaner environment.

Sustainable agricultural technology is the future—and it will change the game.

(1) According to the passage, smart irrigation can ____. A. make full use of every drop of rain B. decide crops' growing environment C. help farmers water the crops when necessary D. support the growth and harvest of crops efficiently

(2) From "Drones" part, we can learn that ____. A. drones can help provide water and fertilizer B. drones help farm work in a more efficient way C. farmers can fly in their drones to check on crops D. farmers can record the details about their drones

(3) What is the final goal of agricultural sustainability? A. To help us have a better environment. B. To make farmers work more efficiently. C. To raise the production of crops quickly. D. To reduce farmers' boring and tiring work.

(4) The passage is mainly to ____. A. think highly of the agriculture department B. make sustainable agriculture technologies better C. change farmers' misunderstanding of agriculture technologies D. stress the importance of sustainable technologies in agriculture

On March 20，2021，the Sanxingdui site （三星堆遗址） in Guanghan，Sichuan drew the world's attention. Chinese archaeologists （考古学家） have found more than 500 cultural relics （文物） in six pits （坑） at the site，which dates back over 3，200 years.

The Sanxingdui site，which was first discovered by a farmer in 1929，is believed to be the site of the ancient Shu Kingdom （蜀国）. The kingdom was a center of civilization （文明） along the Yangtze River.

In 1986，archaeologists discovered two pits. They believed they were used for large sacrificial ceremonies （祭祀仪式）. At that time，over 1，000 relics were found.

The discovery of Sanxingdui raised an important question about the origins （起源） of Chinese civilization. The ancient Shu civilization that built Sanxingdui is believed to be one of the earliest examples of Chinese civilization. The site，along with the Liangzhu and Shijiahe sites along the Yangtze River，shows that the birthplace of Chinese civilization might not have been only along the Yellow River Basin （流域） in north China.

The newly-discovered relics are similar to those found in 1986，and they further support the idea that the pits were used for sacrificial purposes.

New kinds of cultural relics have also been dug up. For example，experts found a kind of ancient bronze jar （青铜罐） that was used for holding water or wine. They also found a jade （玉） relic commonly found at 5，000-year-old Liangzhu Archaeological site in Zhejiang Province.

"These relics show that the Sanxingdui site had a close connection with Central China，but it also marks an ancient civilization in Sichuan with strong creativity，" said Chen Xiandan，a member of the excavation （发掘） project.

(1) What do the newly-discovered relics suggest？ A. More than 1，000 relics were found in Sanxingdui since 1986. B. Sanxingdui was found earlier than Liangzhu Archaeological site. C. Sanxingdui is more important than the sites in north China. D. The civilization in the ancient Shu Kingdom was creative.

(2) Which of the following is NOT true according to the passage？ A. The Sanxingdui site is in the city of Guanghan，Sichuan Province. B. Sanxingdui，Liangzhu and Shijiahe sites are along the Yangtze River. C. A Chinese archaeologist discovered the first Sanxingdui relics. D. The Sanxingdui site was built by the ancient Shu civilization.

(3) What does the underlined word "they" in Paragraph 3 refer to？ A. Pits. B. Archaeologists. C. Ceremonies. D. Relics.

(4) Where is the birthplace of Chinese civilization according to this passage？ A. Along the Yellow River Basin （流域） in north China. B. Along the Yangtze River. C. Around Shu Kingdom along the Yangtze River. D. Along the Yellow River and the Yangtze River.

(5) What does Chen Xiandan intend to express in the last paragraph？ A. Sanxingdui site had a close connection with modern civilization. B. People in Sichuan are very creative and good at finding cultural relics. C. Ancient civilization in Sichuan is full of creativity and it is part of Chinese civilization. D. There will be more new kinds of cultural relics to be dug up.

With two in five plant species（物种）at risk of disappearance，the Germplasm Bank of Wild Species（中国西南野生生物种子资源库），or GBOWS，in Yunnan Province is racing against time to protect the nation's plant species.

Founded in 2007，GBOWS is a research and preservation（保存）bank for rare and endangered plants and animals. As the largest bank of wild species in Asia in terms of species，GBOWS has preserved 85，046 seeds from 10，601 species and 60，262 biological samples（生物样本）of 2，203 animal species. The number of seeds at GBOWS is close to that of the world's biggest seed bank—the Millennium Seed Bank in the United Kingdom.

So how does the bank work？Scientists collect the endangered and useful wild species and send them to the seed bank. Once the seeds arrive at GBOWS，they're dried and preserved in a special room. X-rays will make sure the seeds are undamaged and no insects are hidden inside after they are cleaned and separated from broken ones. The seeds are then frozen（冷藏），preserved in glass bottles and placed in a huge room at -20℃ for long-term preservation. Each bottle has a barcode（条形码）. By scanning it，scientists can view detailed information about the seeds inside.

The bank works with many international organizations on collection，exchange and research. It has 2，176 sets of seeds from 45 countries and regions，with each set including thousands of seeds.

"As China has rich and special plant and animal species，we plan to increase the number of our collections and conduct further research to protect endangered species，" says Li Pei，a worker at GBOWS. "If the world ends one day，these collections will bring hope of a new beginning to life on Earth. "

(1) What's the purpose of Paragraph 1？ A. To show us how to name a bank. B. To introduce the topic of the passage. C. To call on people to value their time. D. To tell us the importance of plant species.

(2) Which of the following is correct？ A. GBOWS has 10，601 animal species in total. B. All of the seeds at GBOWS are found in China. C. The number of seeds at GBOWS is the largest in the world. D. Other Asian banks have fewer wild species than GBOWS.

(3) Which is the right order according to Paragraph 3？

①The seeds are sent for X-rays.

②The dried seeds are put into a special room.

③The seeds are put into a room at -20℃.

④The broken seeds are taken out.

A. ②→④→①→③ B. ②→①→④→③ C. ④→②→①→③ D. ④→①→③→②

(4) According to Li Pei，the work at GBOWS is ____. A. creative B. challenging C. meaningful D. dangerous

(5) What's the passage mainly about？ A. The bank's ways to preserve seeds. B. The contributions GBOWS has made. C. China's efforts to protect plant species. D. A bank that collects seeds for the future.
