The microplastics(微型塑料) problem in the oceans...

The microplastics(微型塑料) problem in the oceans has made its way to sea turtles in a big way. A new study has found microplastics in the stomach of every single turtle they tested—a total of 102 sea turtles.

The researchers tested more than 100 sea turtles from all seven kinds and three different oceans, and they were looking for man-made things less than 5 mm long. The most things the team found were fibers, which most likely came from clothing and fishing equipment.

“The influence of these particles on turtles is unknown,” said Emily Duncan. “Their small size means they can pass through the stomach without causing a problem, as is frequently reported with larger plastic pieces.”

The researchers found more than 800 man-made particles in the turtles, but since they only tested part of the stomach, they believe the total number of particles could be 20 times higher. They don’t know how the turtles take in the particles, but they think they are from polluted seawater and polluted plants.

Professor Brendan Godley said that eating microplastics isn’t the biggest problem to sea turtles at the moment, but it is a clear sign that we need to do a better job watching global waste.

This turtle study shows that we need to reduce the amount of plastic waste, so we can keep clean and healthy oceans for future people.

1.The underlined part in paragraph 1 probably means “________”.

A.has gone into B.has made great effect on

C.has been walking to D.has tried to escape from

2.How did the researchers find out the microplastics problem？

A.By giving examples. B.By comparing sea life.

C.By studying different sea animals. D.By testing turtles from different seas.

3.What can be inferred from Emily?

A.Larger plastic pieces cause trouble to sea turtles

B.Eating microplastics is the biggest danger to sea turtles

C.Scientists know clearly how sea turtles eat plastic pieces

D.The number of particles inside sea turtles is much higher

4.The purpose of the text is to call on people to ________.

A.stop killing sea animals B.find out more plastic waste

C.control pollution to oceans D.carry out further researches

Not long ago, Egypt marked the 150th anniversary of the opening of the Suez Canal. The canal connects the Mediterranean Sea to the Red Sea and the Indian Ocean. It helped speed world trade between the East and the West. But the man-made waterway has also helped speed the rise of other things, such as invasive(入侵的)non-native species (物种). Scientists say the invasive creatures have damaged the Mediterranean’s environment and caused native species to disappear.

The number of non-native creatures has risen since the Suez Canal was widened in 2015. The “New Suez Canal” has raised concerns in Europe and brought disagreement from many Mediterranean countries. Bella Galil is an Israeli biologist who has studied the Mediterranean for over 30 years. She says much of the ecological(生态的)damage cannot be repaired. She said urgent action is needed to ease the effects of the invasive fish and other sea life.

Galil works at Tel Aviv University’s Steinhardt Museum of Natural History. She noted that the widening and deepening of the Suez Canal has created a “moving aquarium” of species. These creatures could make coastal waters almost unusable for human beings. Galil believes the number of invasive species has reached 400. That is twice the number 30 years ago. She said this is a “historic example of the dangers of unintended consequences.”

Israel is now dealing with huge numbers of poisonous(有毒的) jellyfish that affect coastal power centers and keep people from visiting the seashore. Other poisonous species, such as the lionfish and silver-cheeked toadfish, are also appearing.

Galil said the problems of invasive species can be compared to those of climate change, pollution and over-fishing. She argues that the new species have caused a major “restructuring” of the environment. This has endangered native species.

Some experts have suggested that increasing salt levels in the canal itself could create a barrier(障碍物) that would keep invasive species out.

1.What lesson can we learn from the effects of the Suez Canal?

A.Seeing is believing. B.Every coin has two sides.

C.Let nature take its course. D.Everyone makes mistakes.

2.What’s the attitude of many Mediterranean countries towards the“New Suez Canal"?

A.Uncaring. B.Unclear. C.Supportive. D.Against.

3.What is the ecological environment like after the Suez Canal reconstruction?

A.It is from bad to worse. B.It remains the same.

C.It improves a great deal. D.It has become a completely new one.

4.Why did Galil mention climate change,pollution and over-fishing in paragraph 5?

A.To add some background information. B.To stress the harm of invasive species.

C.To solve the problem of invasive species. D.To compare their similarities and differences.

The Great Barrier Reef has seen its third mass bleaching (大规模白化) event in five years. For the first time, all three sections of the Australian reef have been badly affected. The damage happened in February when the area was exposed to the hottest month of water temperatures on record.

Surveys conducted by Terry Hughes at James Cook University in Australia and his team during March made it known that 25 percent of the reef had been badly bleached and 35 percent bleached to some degree. The northern, central and southern sections of the reef were all hit.

Terrible bleaching also struck in 1998, 2002, 2016 and 2017, but was limited to one or two sections. This is the first time that all three sections have experienced terrible bleaching at exactly the same time, says Hughes. “It’s heartbreaking.”

Some of the damaged corals（珊瑚）will survive, including more heat-resistant（耐热的） species. But many others were probably “literally cooked” at the peak of the heatwave in early 2020, says Hughes. Others will die more slowly from stress over the next few months, he adds. Hughes has serious concern about the southern reef, which was mostly unaffected in former bleaching events and hasn’t developed the same heat resistance as other parts.

The 2016 and 2017 events killed about half the coral on the reef. It usually takes a decade for even fast-growing corals to recover, meaning the latest damage will seriously weaken the reef’s ability to recover, says Hughes. The high frequency of mass bleaching in recent years has been driven by climate change, which results from human activity and is steadily raising ocean temperatures. The only way to deal with the problem is to immediately reduce the release of greenhouse gases, says Hughes.

1.What can we learn from the surveys by Hughes and his team?

A.The entire reef has experienced bleaching.

B.The surveys about the reef are done once a year.

C.The hottest month of water temperatures is February.

D.60 percent of the reef suffered from serious bleaching.

2.Why is Hughes worried about the southern reef most?

A.Many corals will die slowly from stress.

B.It has been badly bleached for several years.

C.It hasn’t formed the ability to fight against the heat.

D.The government hasn’t shown any concern about it.

3.What is this text mainly about?

A.Surveys on reef bleaching.

B.A report on climate change.

C.An investigation into global warming.

D.Warning messages on human activities.

I don’t think I can recall a time when I wasn’t aware of the beauty of the ocean. Growing up in Australia, I had the good fortune of having the sea at my side. The first time I went to Halfmoon Bay, I suddenly had the feeling of not being able to feel the ground with my feet anymore.

For my 10th birthday, my sister and I were taken out to the Great Barrier Reef. There were fish in different colors, caves and layers of coral. They made such an impression on me. When I learned that only 1 percent of Australian’s Coral Sea was protected, I was shocked. Australian marine life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45 percent of the world’s reefs are considered healthy.

This statistic is depressing, so it’s important for us to do everything to protect them. The hope that the Coral Sea remains a complete eco-system has led me to take action. I’ve become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean’ s species will all have a safe place forever.

Together, Angus and I created a little video and we hope it will inspire people to be a part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.

1.From the underlined sentence in Para.1, we can learn the author ________.

A.seldom went surfing at the sea

B.forgot his experiences about the ocean

C.never went back to his hometown

D.had a wonderful impression of Halfmoon Bay

2.According to the second paragraph, Australian marine life ________.

A.is escaping from the Coral Sea gradually

B.depends on reefs for living greatly

C.may be faced with danger

D.is protected better than that in other oceans

3.The Protect Our Coral Sea activity is intended to ________.

A.contribute to a complete eco-system

B.prevent more marine species being endangered

C.set up a large nature reserve for reefs

D.raise more teenagers’ environmental awareness

4.Angus and the author created a little video to ________.

A.urge more people to take action to protect the marine species

B.inspire more people to explore the secret of the ocean

C.share their childhood experiences about the ocean

D.bring back to people their memories of ocean species

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.

"When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.

Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental non¬governmental organization, and put his plan for an ocean cleanup device into action.

After years of research and develop¬ment in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（挡板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.

Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.

"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持续的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"

1.The underlined word “match” in Paragraph 2 probably means “_________”.

A.compare B.equal

C.measure D.cover

2.Why did Boyan Slat create the Ocean Cleanup?

A.To collect ocean plastic waste.

B.To help to invent System 001/B.

C.To protect the living environment of fish.

D.To do research on the ocean environment.

3.What can we know about System 001/B?

A.It can collect and recycle garbage at the same time.

B.It can only gather ocean waste which floats on the water.

C.It aims to clear up the Great Pacific Garbage Patch in five years.

D.It is an ocean-cleaning device which has already been put to use.

4.What does Slat want to tell us according to the last paragraph?

A.Young generations care less about the environment.

B.The future ecology of the oceans is deeply worrying.

C.People should work hard to decrease plastic pollution.

D.It's quite difficult to repair the damage to the environment.
