3 . Landslides and earthquakes are even more dangerous now than in the past because around half of the world’s population now live-in cities. Many people in cities and towns in South America and Asia are at risk from landslides. In April 2017,the city of Mocoa in Colombia was hit by a landslide, leaving many dead and injured. A great number of people live at risk from earthquakes too. These have claimed more than 1.6 million lives in the last hundred years.
Most disaster experts believe that things could get a lot worse. Professor Hou Ming of Peking University studies volcanoes. He warns that the world has not seen the worst yet. The worst eruption in human history was probably Mt Tambora in 1815,in Indonesia. Dust from the volcano rolled across the Earth’s skies. There was no summer in Europe and America the following year. But evidence shows that 73,000 years ago there was a much greater eruption. “It reduced temperatures by maybe 6°C in some places, and the whole planet was sent into winter for years. And there are about two of these events every 100,000 years...”
Why is Mt Tambora mentioned in the text?
| A．To demonstrate the world could get worse. |
| B．To show volcano eruptions have taken many lives. |
| C．To explain a natural disaster by showing an example. |
| D．To describe the worst volcano eruption in human history. |
4 . A restaurant owner’s remarkable act of heroism saved many lives during a storm in Rolling Fork, Mississippi, which destroyed a local restaurant.
Tracy Harden, the owner of Chuck’s Dairy Bar, rushed her staff into a walk-in cooler moments before a tornado hit the establishment on Friday.
Harden spoke to Good Morning America reporter Robin Roberts on Monday alongside two employees, Barbara Pinkins and Carolyn Washington, who were both in the restaurant when the tornado hit.
As the horrible tornado tore through the local area, Harden said she only had a minute of advance notice before it came moving rapidly through the restaurant.
“I got two text messages back-to-back from my sister and my daughter in Vicksburg and they both said, “There’s a tornado down, get to a safe place.’ At the same time I had my teenage cashier came running towards the back of the building saying, ‘My mother is on the phone and she said there is a tornado down here.’ At that point, most of us were towards the back of the building and the lights flickered(闪烁). And I just shouted, ‘Cooler!’ And my husband opened the cooler door and started pushing us in.”
Harden said that once her husband got them all inside, including himself, “he lost control of the door, the wind took the door and somehow he was able to get the door back.”
“Just before it shut, he looked up and he said, ‘I see the sky,’ so that let us know that this was way worse than anything we could have imagined,” she continued. “And the roof was gone.”
Pinkins, meanwhile, recalled the chaos(混乱场面)before the tornado touched the restaurant, as Harden led people to safety. She said she remembered hearing Harden say,“Calm down. Everybody gets to the cooler!”
“By the time we got to the cooler, I couldn’t hear anything but the ceiling falling,” Pinkins said through tears, hugging Harden.

6 . Our Earth’s oceans contain some of the most valuable resources. As the use of fossil fuels and greenhouse gas emissions began to rise in popularity, the polluting of the Earth’s oceans did as well, leaving lifelong effects on all of its ecosystems.
Commercial whaling has left several whale species in danger of extinction. The blue whales of the Antarctic have less than one percent of their original numbers. Over 90 percent of plastic isn’t recycled, and a large part of that number finds its way into the ocean and surrounding beaches. The huge amount of plastic damages whales’ existence. Plastic is being eaten by sea life as well as entangling(缠住) them, putting them all at major risk. Without change, our Earth’s oceans will not be able to continue on for much longer.
The Delta Corporation was set up in 1972, later known as Ocean Conservancy. In the beginning years of Ocean Conservancy, its main initiative(倡议) was the Whale Protection Fund. This fund focused on saving the species and protesting against commercial whaling. They gained the support of many.
Ten years later, the International Whaling Commission finally banned commercial whaling. It then changed its focus to not only whales but to seals and sea turtles as well. Though they made great progress with these animals, they came to the conclusion that these animals cannot develop well without a healthy, sustainable environment. The workers of Ocean Conservancy then expanded their focus to the marine ecosystems and habitats.
Ocean Conservancy is one of several organizations working toward a common goal: saving the Earth’s oceans. They have started doing this by creating the Whale Protection movement that still exists. Though they have made significant progress throughout the years, there is still much to be done. Only when the common goal is shared by all groups, governments, and individuals, will real change be made. If successful, the electric bicycle meal program will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement.

8 . The sighting of a new family of gray wolves in Oregon’s Cascade mountains has given wildlife protectors hope that the recovery of the endangered animal in the state is on the way. The state’s fish and wildlife department (部门) said a group of two adults and two babies was recorded by a track camera in August.
The wolves were found in the area of Warm Springs and officials have named it AKW — a new area of known wolf activity. If the group still has all four members surviving at the end of the year, the animals will be known as the Warm Springs group, the state’s third one in the northern Cascades. “Wolves will move to different places, but when we have resident wolves, like we know they’re sticking in that area, that’s when we create an AKWA to make sure the wolf count rise constantly.” the agency’s worker, Michelle Dennehy, told USA Today.
Many years of hunting of gray wolves almost made them die out across the nearby 48 US states by the middle of the last century. In Oregon at the end of 2009 only 14 wolves were known to exist. With protections from the Endangered Animals Act beginning in 1974, numbers have risen slowly since, to 175 in Oregon by the end of last year, living in more than 35 groups.
“I hope this will be an exciting new chapter in the story of wolf recovery in the state. Having more wolves establish families in western Oregon will be important for the long-term survival of these beautiful animals,” Amaroq Weiss, senior wolf protector at the Center for Biological Diversity, said in a statement.

9 . At 5:13 on the morning of April 18th 1906, the city of San Francisco was shaken by a terrible earthquake. A great part of the city was destroyed and a large number of buildings were burnt. The number of people who lost homes reached as many as 250, 000. About 700 people died in the earthquake and the fires.
Another earthquake shook San Francisco on October 17th, 1989. It was America’s second strongest earthquake and about 100 people were killed. It happened in the evening as people were travelling home. A wide and busy road which was built like a bridge over another road fell onto the one below. Many people were killed in their cars, but a few lucky ones were not hurt.
Luckily the 1989 earthquake did not happen in the centre of town but about 50 kilometres away. In one part of the town a great many buildings were destroyed. These buildings were over 50 years old, so they were not strong enough. There were a lot of fires all over the city. The electricity was cut off for several days too.
Why do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates. At San Francisco the Pacific plate which is moving towards the northwest meets the North American plate. The Pacific plate is moving very slowly—at 5.3 centimetres a year. Sometimes these two plates stop and do not move for years. Then suddenly, they jump and an earthquake is felt. As a result of the movement of these plates, west America near the sea has always been a bad place for earthquakes. When the 1906 earthquake happened, the Pacific plate jumped 5-6 metres to the north.
Scientists are afraid that one day an even bigger earthquake will hit the area around San Francisco. They call it “The Big One”. However, people today are still building more houses. The population in and around San Francisco is now ten times more than it was in 1906. This means that if there is another big earthquake, a great many houses and buildings will be destroyed.
