The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature.

David Tilman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how a diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized (工业化), population increased and earnings rose, more people began to adopt what has been called the Western diet.

The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tilman says overweight people are at greater risk of noninfectious diseases like diabetes (糖尿病) and heart disease.

Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20­year period. And that is happening all across the world, in Mexico, in Nigeria and so on.

And, a diet bad for human beings is also bad for the environment. As the world's population grows, more forests and tropical (热带的) areas will become farmlands for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.

Mr. Tilman calls the link between the diet, the environment and human health, “a trilemma” — a problem offering a difficult choice. He says one possible solution is leaving the Western diet behind.

1.According to the passage, more greenhouse gas might be given off in the future from ________.

A．transportation　　　　　　 B．developing countries

C．agriculture　　　　　　　　 D．developed countries

2.David Tilman believes that ________.

A．the diet, the environment and human health are closely connected

B．the Western diet is the only choice as the nation industrializes

C．people in tropical areas are more likely to have heart disease

D．traditional diets are more balanced than the Western diet

3.We can infer from the passage that ________.

A．Nigeria has the largest number of diabetes cases

B．overweight people are at higher risk of infectious diseases

C．the examined information comes from developing countries

D．industrialization contributes to the spread of the Western diet

4.The main purpose of the passage is to　 ________.

A．call on us to protect the environment

B．warn us of the danger of the Western diet

C．remind us of the importance of health

D．advise us to have a balanced diet

The COVID-19 pandemic has spread far and wide. Because of this, countries around the world have carried out containment measures 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 a lot 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.

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. “The drop is seriously wild,” she wrote. 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.

1.What did seismologists find out recently?

A.More smaller earthquakes are likely to happen.

B.Less seismic activity has been detected recently.

C.Reduced seismic vibration makes Earth quieter.

D.Seismic noise is caused by vibrations underground.

2.What can we learn from the text?

A.More seismic noise is being picked up.

B.More data on smaller earthquakes is being collected.

C.Scientists will shift their focus to smaller earthquakes.

D.Future big earthquakes can be more accurately predicted.

3.What does the underlined word “echoed” in paragraph 5 mean?

A.Questioned. B.Demanded.

C.Explored. D.Repeated.

4.What can we conclude from the last two paragraphs?

A.The drop in seismic noise is unique to Europe.

B.Seismic noise is mainly caused by human activity.

C.Many seismologists wanted tighter restrictions for their research.

D.The phenomenon proved that people are practicing social distancing.

Three other Canadian cities came in the top 20. Montreal and Vancouver tied for ninth and Toronto came in at 18th.

The scores are based on air pollution levels, availability and quality of hospitals and medical supplies, as well as the efficiency of waste removal and sewage systems.

In America, the lowest scoring city was Atlanta, which was ranked 76th. Athens was the lowest scoring city in Western Europe, ranking 120th because of its air pollution. London was ranked 59th.

1.How many Canadian cities are in the top 20?

2.Which of the following is NOT taken into account when the cities were scored?
