Dangers from Outer Space
What is the greatest threat to life on our planet? Is it climate change? Shortages of food or water? Or might an altogether bigger danger come from somewhere further away: space?
We’re not talking about an attack by little green men here. Instead, how about being hit by a large falling star, beat by deadly universal rays or fried by the energy of an erupting star?
It wouldn’t be the first time that our Earth has had a rough ride over the last 3.7 billion years, with some disastrous events. The most famous mass extinction(灭绝)was 66 million years ago, when it’s widely believed that a meteorite(陨石)killed off the dinosaurs. A 110-mile-wide crater in Mexico with the same geological age supports this theory.
Believe it or not, this wasn’t the worst catastrophe in our planet’s history. That was when 96% of life was wiped out at the end of the Permian period, 252 million year ago. Scientists don’t know for sure why this happened, but any potential explanations carry with them the possibility that similar events could happen again.
Some experts believe that our Sun has a twin star which is too far away to observe directly. This huge sleeping star could twist the paths of orbiting icy rocks and cast them towards the rest of the Solar System.
Is this what happened 252 million years ago? Or is there instead, perhaps, a distant, ninth plant in our Solar System which pulls in passing comets(彗星)and sends them dashing our way?
The Sun that has given us the warmth is gradually turning into a deadly enemy. Like all stars, it is slowing dying, burning through its energy supplies. As it does so, it expands, and in about 2 billion years it will have grown so much that the heat will make life on planet Earth unbearable.
While all this sounds a little horrible, take comfort from the fact that the chance of being hit by a huge interstellar projectile(星际碰撞物)is unbelievably slim, and that 2 billion years is a very long time.
1.When did dinosaurs die out according to the passage?
A. 3.7 billion years ago. B. 252 million years ago.
C. 66 million years ago. D. 2 billion years ago.
2.Why was 96% of life destroyed at the end of the Permian period?
A. The cause is still unknown.
B. A huge falling star hit the earth.
C. A twin star cast icy rocks towards the Solar System.
D. A ninth planet pulled in passing comets.
3.What can we learn from the passage?
A. All stars will eventually run of energy.
B. Our planet will be attacked by little green men.
C. We will be fried by the energy of an erupting star.
D. A huge sleeping star will hit the earth in millions of years.
4.What is the author’s attitude toward the dangers from outer space?
A. Frightened. B. Relieved.
C. Worried. D. Doubtful.

From the outer of New York to the heart of Singapore, nature is everywhere you're not looking in some of Earth's most crowded big cities. Outdoor adventure is often just a few stops on the train - or a short drive- away from the annoying crowds. Here are a few favorites to get you going:
Mount Hollywood Trail, Los Angeles
It's not a skyscraper or a Ferris wheel, and there's no expensive restaurant up top. But if you want an absolutely unforgettable, no-admission-charged, 360-degree view of the entire Los Angeles region , it's yours. All you have to do is walk a little. One of the preferred exercise routes, the Mount Hollywood Trail, is easily accessed from the parking lot of the famous Griffith Observatory; you see what you get at the end of this steep 1.5-mile trail, which winds its way through the Griffith Park wilds up to the mountain's 1,640-foot peak.
Bronx River, New York
It may not be on your Top 10 list of things to do when you finally get to the Big Apple, but exploring the almost-secret river that flows through one of New York's most mysterious boroughs (自治市) is an unforgettable experience. The Bronx River Alliance, a non-profit group that has worked tirelessly to bring the much-abused river back to life , operates cycling and canoeing trips along the river, from the rugged Hunts Point section down near the harbor on up through the borough.
Southern Islands, Singapore
Believe it or not, tightly packed Singapore does have plenty of open space left . There are actual trails right in the middle of everything, if you know where to look . But to really get away from it all, the Southern Islands, a small group of little green dots just off the city-state's southern shoreline, are just the thing.
Lee Valley, London
This East London river valley changed last summer, when anyone near a television got an eyeful of Olympic Park, built directly in the middle of the valley. Inside the park, beautifully landscaped sections quickly became a favorite relaxation spot for games goers. At present, you'll find miles of walking paths worth exploring. Start at the Waltham Cross train and follow the signposted walking route southbound, guiding you past important historic industrial areas, through interesting city neighborhoods, past the western side of Olympic Park and on to the Thames.
1.If someone wants to enjoy an unforgettable experience for free , he can go to ______.
A.Mount Hollywood Trail and Bronx River
B.Mount Hollywood Trail and Southern Islands
C.Lee Valley and Southern Islands
D.Bronx River and Lee Valley
2.The writer of the passage wants to ________.
A.inform the readers that nature exists in crowded big cities
B.appeal to more people to outdoor adventure
C.recommend several historical spots to readers
D.present various approach to outdoor adventure
3.We know from the passage ________.
A.it’s difficult to find a proper trail in packed Singapore
B.the Thames is not far away from the East London river valley
C.The Bronx River Alliance has succeeded in running the river
D.you may have trouble reaching the Mount Hollywood Trail

Over the last 50 years, illegal trade in wildlife has become one of the greatest threats to our natural world. Traffickers (贩子) are exploiting communities in developing areas, driving them to illegally hunt down animals for their body parts. These criminal networks only pay a tiny portion of the final price they get for the animals they receive. Beautiful animals are shipped off to faraway markets, whole or apart.
Angry? We’ve barely started yet. The animal parts are being shipped along with weapons, drugs, even people". These heartless profiteers don’t care about the destruction they cause. Live animals are hidden during transport with no thought for their survival. Many of them don’t make it. Perhaps it’s a mercy when traffickers choose to kill and freeze the animals, before hiding them in the containers the size of a small bus. It’s not one or two animals here and there—it’s entire species that we are seeing driven towards extinction, lost forever from our global heritage. And for one reason alone: to put more money in the pockets of these criminals—whatever the cost.
Now, humans reap as they have sown. COVID-19 has “affected us all. It’s breaking our economies. It has sealed us in our homes and is attacking the weakest among us. In a short period? almost every person on the planet has been affected and we still don’t know the final toll. The source could well be these criminal profiteers. We don’t know for certain how the pandemic started. Some scientists suggest that the disease might have been transferred to a person from a pangolin (穿山甲) being traded illegally in one of these markets—these are most trafficked mammals in the world, with over a million consumed by the trade since 2000.
Yet we would never have imagined that these markets for body parts of wild animals would affect us in this way. It’s time to say “enough”. Dr, Rebecca Drury, Head of Wildlife Trade at Fauna & Flora International (FFI) says, We would like to see stronger action to stop illegal hunting, trafficking and consumption of illegally- sourced wildlife. It is no longer an option to ignore the dangers of illegal and unregulated wildlife trade and consumption, to human health and to healthy, functioning ecosystems needed for life on earth to thrive. We must ensure that the lessons from COVID-19 pandemic are applied to prevent repeats of this global crisis.
The governments of the world are doing what they can. But while bans are put in place, the greedy individuals driving the trafficking will try to use their illegal networks to keep selling, lining their pockets until they are stopped. It’s precisely because this is a trade that happens in the shadows, so we must stop it at source. That’s why FFI is raising funds—to help put a stop to this mean trade. To do so they are asking readers of The-Week to make an urgent contribution today.
1.What can we know from Paragraph 2?
A.Most of the live animals can’t survive the long trip.
B.Most of the live animals were killed and frozen during the trip.
C.Generally, the animal parts won’t shipped along with drugs or people.
D.Traffickers will give it a second thought when considering the cost of the trafficking.
2.What does the author want to convey mainly in Paragraph 3?
A.Humans are paying a price for the illegal animal trafficking.
B.COVID-19 has brought disasters to humans.
C.COVID-19 originates from the pangolin.
D.Scientists have known the transferring path of COVID-19.
3.Which of the following statement is TRUE?
A.Dr Rebecca Drury suggests stopping the trade of wildlife.
B.The most trafficked mammals in the world are the pangolin.
C.FFI is trying to find the source of the illegal wildlife trade.
D.Humans can prevent global crisis if they stop the illegal wildlife trade.
4.What is the purpose of the article?
A.To show us millions of endangered animals are being cruelly killed.
B.To confirm illegal wildlife trade threatens some of our beloved animals.
C.To discuss how to stop the trafficking.
D.To call on immediate action to end the illegal wildlife trade.
