Around the world,facial recognition（FR人臉識(shí)別）has slowly become a part of our daily life.

After helping people to make payments and open bank accounts,FR now is used in the subway of Zhengzhou,Henan Province. FR was introduced in September and now it can be used by passengers who link their online payment systems to the subway's smartphone app. China Daily reports that other cities in China,including Beijing,are testing a similar system.

It's not hard to see why. FR technology could help speed up security （安全） checks greatly. Yuan Xiaoqin,a park manager in Hangzhou,told CCTV the reason why the park upgraded （升級(jí)） its entry system,"FR can help a visitor enter the park in two or three seconds. Fingerprint information sometimes isn't sensitive （靈敏的）,especially when the fingers are injured or too dry." Before,the park used a fingerprint entry system.

However,there are some problems with the use of FR. Some people are afraid that their personal information will be leaked.

In fact,sometimes people can refuse the app if they don't want their facial information disclosed （暴露）,but sometimes people don't have a choice.

1.Which city is using facial recognition in the subway?

A.Zhengzhou. B.Beijing. C.Hangzhou. D.Chengdu.

2.How can a passenger use FR technology to take the subway?

A.Buying a smartphone in the subway station.

B.Opening a bank account on a smartphone.

C.Taking a photo of his face and sending it out.

D.Linking his online payment systems to the subway's smartphone app.

3.Why did the park improve the entry system?

A.Because FR technology was more fashionable.

B.Because sometimes the system didn't work well.

C.Because the system could injure visitors' fingers easily.

D.Because the manager found it hard to manage the visitors.

4.What does the underlined word "leaked" mean in Paragraph 4?

A.Secret smartphone apps are used, B.Secret information is known by others.

C.Facial recognition technology is used widely. D.Personal information is stored in the smartphone.

Once upon a time there was no tea at all in England. People there used to drink a light beer. No coffee or milk but large glasses of beer stood on the breakfast table.

When tea was first brought to England, an old couple got some as a special treat. But they do not know how it should be used. They cooked the leaves in hot water, and spread them on a piece of bacon (熏肉) which they were going to have for dinner. They ate the leaves, and threw the tea away! However, tea is becoming as popular as coffee and milk in England today.

Tea is the leaf of a plant which grows widely in China, Japan and some other countries. Tea farmers usually grow many tea plants on a large piece of land. When the leaves are ready to be picked, it is the busiest time for tea farmers in a year. They pull off the leaves and dry them.
