Scientists are not alone in the fight against the virus, as various products and apps are giving them a hand. Here are some examples.

Drones (无人机)

Drones have played a major role in disinfection (消毒). Police officers also use them to spread the latest information. What's more, they use drones to remind people to wear masks or warn them not to gather in large groups.

Robots

Robots are good helpers on the frontlines. They do many tasks in hospitals, including sending medicine or meals, doing disinfection and measuring patients' body temperature. This not only greatly reduces the burden for medical workers, but also prevents the cross-infection (交叉感染).

Mini-programmes

Different mini-programmes, or apps that you don't need to download but can use on Wechat, have also come to help. For example, you can check whether you have unknowingly travelled alongside infected patients. Community workers can collect information about people more easily with the help of mini-programmes.

Health QR codes (健康码)

People in more than 100 cities can get their own health QR codes by applying through Alipay or Wechat. This way, they don't have to fill in information like their names, ages and living addresses over and over again when they enter public places.

Imagine you are thinking about entering a senior high school, but have questions. So you go to the school's website to find answers. A message appears on your computer and says, "How can I help?" You are not communicating with a human being, but a chatbot. It is using artificial intelligence (AI) to communicate with you. This might sound strange, but in recent years, chatbots have become an usual tool for banks and large companies around the world.

Having workers answer people's questions and complaints can be expensive. And workers canonly work several hours a day, making customers wait longer for a response (答复). So not only companies, but more schools have also begun using chatbot technology, says Keith Rajecki. He is with Oracle Higher Education, a computer software company that serves these institutions.

Rajecki notes that reducing costs and response time is one of the main reasons why schools and companies are turning to this technology. However, the purpose of many schools is to find ways to better serve students, since students are used to communicating online through Facebook or WeChat, says Rajecki.

Now Oracle is offering many schools a chatbot which can do everything from helping students register (注册) for classes to helping them ask for a few days off. Oracle is not the only company working on chatbot technology. Businesses like AdmitHub and Ivy.ai are involved in similar efforts.

Western Governors University, or WGU, also received a $750,000 award to experiment with a new kind of chatbot. "We're not trying to create a bot that answers simple questions," said Jason Leven, the director of WGU Labs. "We're trying to create a chatbot that can help decision making for students."

Ian Jacobs is with the market research company Forrester. He suggests that technology like chatbots can work well if it is able to do what users ask of it. Jacobs says the problem will appear when cost cutting becomes an important reason for using the technology. This means schools and companies are more likely to try using chatbots for things they are not yet able to do, such as communicating in the way humans do. For one thing, there are hundreds of ways to word even simple requests. For another, chatbots aren't able to deal with emotions (感情). They can't understand how humans feel, not to speak of comforting (安慰) them.

1.Which of the following is not the reason why more schools are turning to chatbot technology?

A.Schools want to serve the students better.

B.Chatbot technology can help schools save money.

C.Students are used to communicating with chatbots.

D.Chatbot technology makes students wait shorter for a response.

2.Chatbots may work well in the following situations except ________.

A.when students want to know more about a school

B.when students are wondering how to register for classes

C.when students want to have two days off because of illness

D.when students are in need of some help because a parent dies

3.The following sentence would best be placed at the end of ________. However, not everyone is ready to consider the possibilities this kind of technology presents.

A.Paragraph 5 B.Paragraph 4 C.Paragraph 3 D.Paragraph 2

4.What can we infer from the passage?

A.A chatbot is able to do whatever users ask of it.

B.A chatbot is a kind of completely new technology using AI.

C.A new chatbot may appear to help students to make decisions.

D.Chatbot technology has been used in both schools and companies.
