2 . Like all mammals, whales need to sleep in order to survive. But they are also air breathers, meaning that they cannot sleep in the water all the time. There are around 90 different types of whale, which can hold their breath for about an hour, depending on the species. However, they usually travel up to the surface to breathe every 15 minutes.     1    

Some scientists have found that whales cannot become fully unconscious or they would drown. To deal with living in the water full-time while having to breathe air, these air-breathers have evolved into voluntary ones, as a way to prevent accidentally breathing in water at inopportune moments.     2     Therefore, they have to be awake and alert at all times to prevent themselves from drowning.

Whales have some of the largest brains on the planet.     3     They can actively decide which part of their brains to use at a given time. This particular way of sleeping can be seen most clearly in captive (圈养的) whales. When whales are sleeping, they can be seen keeping one eye closed while the other remains open.

    4     Some species, like sperm whales, enter a deeper sleep where they hang in groups, vertically, not too far below the surface for just over an hour. Other species, such as the humpback whales, have been observed resting motionless at the surface of the water for only 30 minutes.     5     And, killer whales, which are very socially complex, never swim too far from the other members of their pod, sleeping in close groups.

A．So how exactly do they get any sleep?

B．They continue to swim slowly and regularly.

C．They won’t lose their body temperature by staying still.

D．It’s an interesting dilemma for wholly ocean air breathers.

E．This sleeping technique varies slightly among species, however.

F．Whales consciously control their blowholes with powerful muscles.

G．Sperm whales in particular have the biggest brain of any living mammal.

3 . About 40,000 elephants and 1,000 rhinos are hunted in Africa every year, Poachers kill elephants for their tusks and rhinos for their horns to earn money even though it is against the law. Then other people, called “traffickers”, buy the tusks and horns and ship them out of the country. The traffickers sell the tusks and horns again for even more money, usually in Asia.

It has been hard to catch the criminals. Usually by the time the dead animals were found, the poachers were far away. And when traffickers were caught with tusks or horns, it was impossible to say where the horns came from. Until recently, African scientists are using DNA to help find the criminals and send them to jail.

Now scientists in Africa are using DNA tests to connect traffickers with elephants and rhinos that have been killed. They have used computers to build complete lists of the DNA of almost all of the elephants and rhinos in Africa from any part of the animals-blood, skin, hair, horns, or tusks. This DNA records allowed the scientists to build powerful tools for protecting the animals.

Now when tusks or horns are found on a ship in another country, DNA tests can show where they came from. This information can lead to quick actions in the country where the animals were killed. It can also help police discover patterns in the ways the poachers and traffickers work. With the new DNA information, it is easier to prove that someone has been involved in killing animals for their tusks or horns.

So far, these DNA records have been used to send poachers and traffickers to jail in many countries in Africa. People hope that by punishing poachers and traffickers, they can save the lives of more African elephants and rhinos. That's important, since there are only about 400,000 African elephants and 20,000 white rhinos left.

1. What is the problem in Africa according to paragraph 1?

A．The loss of the tusks and horns.	B．The increasing number of criminals.
C．The decline of habitats of wild animals	D．The illegal wildlife hunting and trading.

2. Why do the scientists record the DNA of all elephants and rhinos in Africa?

A．To do scientific research on the animals.	B．To help save more elephants and rhinos.
C．To track the movements of the animals.	D．To recognize African elephants and rhinos.

3. How does the DNA information of animals help police?

A．By providing evidence of the crime	B．By finding the lost tusks and horns.
C．By discovering the tools of criminals	D．By understanding the habits of animals.

4. What can we infer from the last paragraph?

A．DNA tests can help catch all the poachers and traffickers

B．The number of African elephants and rhinos might grow.

C．It's easy to prevent poachers killing elephants and rhinos

D．The sale of tusk and horn products is illegal in the world.

6 . How to Help Kids Save Our Oceans and Be Environmental Heroes

The world’s oceans benefit us in many different ways. Yet, our oceans are being heavily polluted. We need clean and healthy oceans to protect our own health and to support future generations.     1    

• Do a local clean-up

Beach, lake or river clean-ups are a great way to get children involved in keeping our environment free from rubbish.    2     Less trash in the environment in general is less trash that could get washed away in our bodies of water. Gather the family to pick up rubbish together — the kids will really see the difference it makes to an area that they play in.

• Reuse disposed (废弃的) items

A great way to get kids involved in recycling is to encourage them to find other uses for old items. Instead of throwing something away, help them turn it into art!

Local school children in Rome, Italy recently participated in a “Creating art from waste” workshop. The children took a trip to the local beach and were encouraged to pick up different types of rubbish that could be turned into artwork. “    3     It ends up not being trash anymore, but a beautiful piece of art,” one of the children said.

• Reduce plastic use

More than 70 percent of the plastic we use does not get recycled, and a lot of this plastic waste is swept into our oceans.    4    

Often, pre-packaged fruits and vegetables at supermarkets are a big source of single-use plastic. Getting kids interested in growing their own food is a fun and educational way to cut down on plastic and shorten supply chains of foods. Besides, educate kids to use as little plastic as possible.

•     5    

Fish is an essential part of a balanced diet for many people across the globe.

Unsustainable fishing practices threaten the food security of these communities, both by taking away these marine (海洋的) resources but also by harming their livelihoods. You can help by eating fish that are rich in the sea.

A．Fight against overfishing

B．Eat sustainably sourced fish

C．Even a local park will benefit from a clean-up.

D．Trash isn’t just trash, because you can create loads of things with it.

E．Cutting down on plastic is important if we are to protect our oceans.

F．Here are some simple ways to encourage children to protect our oceans.

G．Recycling plastic is an eco-friendly method to deal with plastic in landfill.
