China’s government has been trying all measures to reduce pollution in the past few years. Now people can enjoy a fresh environment everywhere. The following two graphs are adopted from the column of “City Information” on the webpage of Beijing Review.
Graph 1: Olympic Cities Air Quality Report
| City | Date | API | Major | Air Quality | Quality |
| Beijing | Sep. 8 | 37 | N/A | Ⅰ | Very good |
| Qinhuangdao | Sep. 8 | 52 | PM10 | Ⅱ | Good |
| Qingdao | Sep. 8 | 68 | PM10 | Ⅱ | Good |
| Shanghai | Sep. 8 | 67 | PM10 | Ⅱ | Good |
| Shenyang | Sep. 8 | 88 | PM10 | Ⅱ | Good |
| Tianjin | Sep. 8 | 54 | PM10 | Ⅱ | Good |
Graph 2: Chinese National Standard
| API Values | Levels of health concern | Colors |
| When the API is in this range: | ...air quality conditions are: | ...as symbolized by this color: |
| 0 to 50 | Very good | Blue |
| 51 to 100 | Good | Green |
| 101 to 150 | Slight pollution | Yellow |
| 151 to 200 | Moderate pollution | Orange |
| 201 to 250 | Medium pollution | Red |
| 251 to 300 | High pollution | Purple |
| 301 to 500 | Hazardous | Brown |
Notes:
**API stands for Air Pollution Index(指数).
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.
**Sulfur dioxide(SO2) acts as an acid．Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.

C.Qingdao D.Shenyang.
2.If your city is symbolized by either red or purple, the pollution in your city is .
A.Moderate or high. B.Moderate or slight.
C.Medium or high. D.Medium or slight.
3.Which of the following statements is TURE?
A.With API value below 150 the air is free from being polluted.
B.The colors from purple to Yellow indicate the air quality is becoming much worse.
C.When there are floating solid particles and dust in the air, it is dangerous pollution.
D.On September 8th the color-symbol of Beijing City’s air quality is ‘Blue’.
4.When more citizens are beginning to have labored breathing soon after they are in the open air, it suggests that .
A.there is a large amount of sulfur dioxide in the air
B.it is so cold that they may have caught a cold
C.they are starting to cough or have a fever
D.they must be infected with permanent lung disease

Breathing dirty air can cost someone's life span(寿命) months—even years, a new study finds.Worldwide, air pollution lowers average life spans by a year. Scientists shared their new findings in Environmental Science & Technology Letters.
Air pollution has been linked to many health problems.Most earlier studies has looked at how tiny air pollutants affected rates of illness or death. But now an environmental scientist, Joshua Apte, is going even further. He works at the University of Texas, Austin. He together with his team is looking at life expectancy, hoping to make the threat easier to understand.
PM 2.5 is what scientists call tiny particles of pollution in the air. Higher levels of PM 2. 5 can cause health problems and cut months, if not years, from the average life span. This analysis show show pollution affects life expectancy in different parts of the world.
The World Health Organization(WHO) recommends limiting PM 2.5 to 10 micrograms(微克) per cubic (立方)meter of air. Apte's group used data to try to find how this low level would help people. But meeting the WHO standard won't get rid of health damage from dirty air.That's because even below 10 micrograms per cubic meter pollution still causes huge risks.
Reducing air pollution could increase life expectancy. The scientists also compared how other threats shorten life spans across the globe. These risk factors included smoking and cancer.
These results show that in poor countries, cleaning up dirty air could greatly increase life spans. It could have as big an effect as cleaning up drinking water, or curing lung cancer. However, in wealthier countries air pollution shortens life expectancy by less than half a year. All forms of cancer, in fact, shorten the average life expectancy by more than 3.5 years.“Knowing this can really help people, or policymakers, decide where to spend their money,” says Kirk Smith.
1.What is Joshua Apte's team trying to do?
A.Let people understand air pollution better. B.Know how small air pollutants are.
C.Study the life expectancy of different people. D.Study many different healthy problems.
2.What will happen if one country limits PM 2.5 to 10 micrograms per cube meters?
A.Its people will live a healthy life. B.Its air is very clean.
C.It will get a prize from WHO. D.It still has pollution risks.
3.What can we infer from the last paragraph?
A.Cancer is the leading killer in all kinds of diseases.
B.It's very hard to clean up dirty air in a short time.
C.The study will help different countries take different policies.
D.Reducing air pollution can increase all people's lifespans much.
4.What can be the best title for the text?
A.The Effect of Cancer Is Worse than Dirty Air
B.Air Pollution Is Shortening Lives Worldwide
C.Many Factors Are Affecting People's Health
D.Governments Are Trying to Make Life Span Long

The COVID-19 pandemic has spread far and wide. Because of this, countries around the world have implemented containment measures(实施遏制措施)to help stop the virus in its tracks. As more and more people stay inside to stay safe, the outside world seems to have become much quieter. In fact, scientists have seen this change in their research, too.
Seismologists–scientists who study earthquakes–have heard less seismic(地震的)noise recently. Seismic noise is made from vibrations(震动)in the ground that are caused by things like ocean waves and human activity, such as construction work and traffic. This noise makes it difficult for scientists to pick up seismic activity that is made at the same frequency.
Thomas Lecocq,a scientist at the Royal Observatory of Belgium, located in Brussels, was the first to notice this phenomenon.
According to Lecocq, the amount of seismic noise in Brussels has been reduced by about 30 to 50 percent since mid-March. Interestingly enough, this is around the same time Belgium started its containment measures.
Because of this reduction in background noise, scientists like Lecocq have been able to pick up on smaller earthquakes that some seismic stations–like the one in Brussels–wouldn’t have been able to before.
This phenomenon isn’t unique to Brussels, though. Once Lecocq shared his findings online, seismologists from all over the world echoed similar findings.
Celeste Labedz, a graduate student at the California Institute of Technology, mentioned in a tweet that Los Angeles also experienced less background noise.
Researchers from the UK, France and New Zealand also noted a decrease in background noise since containment measures were put in place.
These global efforts to contain the COVID-19 virus have helped to shed light on seismic activity that may have gone unnoticed. It also shows that people are listening to health officials and following lockdown guidelines.
“From the seismological point of view, we can motivate people to say,‘ You feel like you’re alone at home, but we can tell you that everyone is home.…Everyone is respecting the rules.’Lecocq told CNN.
1.What did seismologists find out recently?
A.More smaller earthquakes are likely to happen.
B.Less seismic activity has been detected recently.
C.Seismic noise is caused by vibrations underground.
D.Reduced seismic vibration makes Earth quieter.
2.What can we learn from Paragraphs 4-8?
A.More data on smaller earthquakes is being collected.
B.More seismic noise is being picked up.
C.Scientists will shift their focus to smaller earthquakes.
D.Future big earthquakes can be more accurately predicted.
3.The underlined word “echoed” in Paragraph 6 is closest in meaning to“______”.
A.questioned B.demanded C.explored D.repeated
4.What can we conclude from the text?
A.human activities cause more seismic noise than ocean waves.
B.The drop in seismic noise is unique to Europe.
C.The phenomenon proved that people are following the lockdown rules.
D.Many seismologists wanted tighter restrictions for their research.
