TheBest Placeto Camp in Each State

Washington-SecondBeach, Olympic National Park

Campers put up their tents right on the sand of thisPacific Northwestbeach. Make a campfire, photograph

sunset over the sea and try to absorb this charming spot with your entire being.

Alaska-Bartlett Cove Campground, Glacier (冰川) Bay National Park

In a state full of natural riches,Glacier Bayis a wonder, home to high peaks, whales, 700 miles of coastline, and

light blue glaciers that flow directly into the sea. Set within temperate rainforest along Bartlett Cove, the park's

only campground is impressively green and an easy jumping-off point for boat tours.

Arizona-Havasupai Campground, Havasupai Reservation

Getting to Havasupai is a challenge. Permits are snatched (剥夺) up almost instantly, and even if you get one

it's a 10-mile hike from the border to reach this rural campground that hugs Havasu Creek. Make the journey,

however, and you're rewarded with a series of great waterfalls and natural pools.

Arkansas-BuffaloNationalRiver

America's first national river travels 135 miles through the Ozark Mountains, winding its way over rapids,

forming peaceful pools and passing rocky cliffs topped by green forest. Plan a float trip and absorb the scenery at

a leisurely pace, pausing for hikes to visitLostValley's caves or the 200-foot waterfalls.

ANew Zealandcouncil has announced a month-long road closure in order to allow a sea lion and her pup to

reach the ocean safely.

John Wilson Ocean Drive in Dunedin will be closed after the New Zealand sea lions made their home at a

nearby golf course and started "regularly crossing the road to get to the beach," according to a Facebook post

from Dunedin City Council.

"You can still visit the area on foot or by bicycle, but please give the sea lions lots of space," continued the

post.

Locals applauded the decision, and one even called for the closure to be made permanent.

"No dogs should be on the beach, either," wrote Gaylene Smith. "We need to protect our beautiful sea life."

Dogs are known to attack sea lions, and Chisholm Links Golf Course, where the sea lions have made their

home, also posted advice to dog walkers in a Facebook update.

"We're lucky to have sea lions on our coastline and we need to share the space with them,as this is what

makes our coastline so unique!" wrote the course on Facebook.

The council went on to explain thatNew Zealandsea lions are endangered, and are one of the world's rarest

species of sea lion.

There are an estimated 12,000New Zealandsea lions left, according to the Department of Conservation.

Under local law, anyone who kills a sea lion could face up to two years in prison or a fine of up to

NZ$250,000(US$178,000).

4. What decision has the Dunedin City Council made?

A. Closing an ocean drive for a month. B. Forbidding entry into a golf course.

C. Forbidding walking dogs outside. D. Closing the nearby beach temporarily.

5. How did the City Council announce the decision?

A. By informing on TV. B. By sending out notices.

C. By posting on Facebook. D. By advertising in a newspaper.

6. What is the attitude of the local people toward the closure?

A. Doubtful. B. Supportive. C. Uncaring. D. Critical.

7. What can we learn aboutNew Zealandsea lions from the text?

A. They are afraid of humans. B. They are a common species.

C. They are being killed by dogs. D. They are under legal protection.

A world in which extinct creatures could be brought back to life came a step closer yesterday. Australian

scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active.

Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out

more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活)

creatures that have been extinct for far longer.

“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are

now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very

important step in bringing back those animals that are extinct. And while I think that technically it is still pretty

difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be

brought back to life in my lifetime.”

The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who

extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the

equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to

grow normally, suggesting the tiger gene had been activated.

Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce

(引起) a functional response in another living organism”.

However, the animal’s entire gene structure would have to be revived in the same way to even begin the

possibility of bringing the Tasmanian tiger back from the dead.

Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could

encourage people’s indifference to the protection of endangered species.

“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is

nothing to worry about because we can fix it up later.”

8. What does the underlined word “breakthrough” in the l paragraph refer to?

A. Scientists have recreated new animals.

B. Scientists have resurrected endangered animal.

C. It has turned out that some creatures would not go extinct.

D. A tiger gene has been extracted successfully and activated.

9. Scientists are carrying out the experiments in order to ________.

A. bring extinct animals back to life

B. transplant the genes of tigers into other animals

C. find out what factors lead to the animals’ extinction

D. find a new way to extract animals’ DNA

10. Mike Archer thinks that ________.

A. scientists now have no technological difficulty reconnecting extinct animals

B. it’ll be a century or so before a Tasmanian tiger walks on the earth again

C. humans have come closer in reconnecting extinct animals

D. reconnecting extinct animals is impossible

11. We can learn from Mick Mooncy’s words that_________.

A. he thought it unnecessary to worry about endangered animals

B. his opinion is in contrast with that of the Tasmanian Government

C. he thought people should be encouraged to protect endangered animals

D. he is concerned that bringing extinct animals back to life may have a negative effect

D

Researchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.

It's not the first time that experts have claimed techniques could develop fruit with unusual features:

scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.

But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes

offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make

food taste “hot”.

“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they

promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the

benefits of engineering hot tomatoes.

Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low

productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high

and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.

Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All

these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using

gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he

said.

12. Why are the tomatoes made hot by the researchers?

A. To test the gene-editing technology B. To improve the amount of the tomatoes

C. To explore ways to harvest more capsaicinoids. D. To make the tomatoes more delicious.

13. For what purpose can capsaicinoids be used according to the text?

A. To put on weight. B. To ease the pain.

C. To improve sleep. D. To better the look.

14. What is Zsogon's attitude to the gene-editing technology?

A. Confident. B. Critical. C. Anxious. D. Doubtful.

15. What's the main idea of the text?

A. An introduction to gene-editing plants.

B. Creating hot tomatoes by gene-editing.

C. Problems with capsaicinoid production.

D. The procedure of producing capsaicinoids.

Have you ever felt stressed? Well, you are not alone, as every person in the world has to face stress at one

time or another. Since stress is a part of life, it is essential to learn how to deal with it. Here are some strategies for

dealing with stress and pressure.

___16___To get rid of this feeling, keep yourself organized. For example, you could keep a daily organizer and

plan your activities. Get your priorities straight and focus on things that are really important. Do not get stuck in

minor issues that only create additional work for you. Break tasks down into manageable bits and tackle them one

by one. Proper planning also helps you avoid the stress of doing things at the eleventh hour.

___17___Doing things that you like such as listening to music, taking a walk, or reading a book can take your

mind off things that bother you. Even doing nothing at all can be beneficial. After a short break, you will feel

refreshed and more able to tackle a problem or a piece of work.___18___This would only cause you more stress

when you have to rush to finish your work in the end.

Finally, do not set such high standards for yourself and others that it leads to dissatisfaction and pressure. If

you aim for perfection all the time, you will end up frustrated and stressed out. Learn to slow down, let go and

look at the positive side of things. If you ace too anxious about something, you will not be able to think clearly and

make good decisions.___19___Focus on what has already been done and what is good. Then, negative stressful
