七、阅读理解
Governments and businesses worldwide are creating smartphone apps to help track (追踪)the spread of COVID-19.
Tracking the spread of a disease is an important step in stopping its outbreak. By tracking down people who have been in contact with COVID-19 patients, health researchers can warn them, and keep COVID-19 from spreading further. This is called "contact tracing"(接触者追踪).
As governments remove COVID-19 limits, they’ll need to be able to quickly find and control new outbreaks. Contact tracing will be an important part of the process.
But because COVID-19 spreads so quickly to so many people, it's almost impossible to trace all contacts with phone calls. That's why many people hope that digital (数字的)contact tracing with smartphones will help.
Most contact tracing apps collect information about where people have gone and the people they've had contact with. The apps can tell users when one of their recent contacts has been found to have COVID-19. Some systems also tell governments or health care workers.
Now many apps have been developed all over the world. But some people worry the apps are being made too quickly and may not protect people's private information.
What do you think of this kind of app
1.Contact tracing apps are mainly used on 　　　　.
A. smartphones B. computers
C. cars D. telephones
2.What should we do to prevent COVID-19 from spreading further
A. We should bring smartphones.
B. We should control all people's movements.
C. We should tell governments or health care workers.
D. We should track down people who have been in contact with COVID-19 patients.
3.What does the underlined word "they" in Paragraph 3 refer to
A. Users. B. Governments.
C. Researchers. D. Health care workers.
4.What's the disadvantage of the contact tracing apps
A. To control the spread of COVID-19.
B. To make health care workers in danger.
C. To trace all contacts with patients.
D. To make people's private information public probably.
5.What could the passage be
A. A story. B. A science article.
C. A notice. D. A speech.
