How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?

In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.

Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces. They are taller, to reach higher branches. They have shorter tusks (象牙), and most importantly, longer trunks to dig for water in riverbeds.

Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families, They drink only every 3-4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders — they seldom root up trees and break fewer branches, and thus keep what little food sources are available. Yong elephants may even eat the dung (粪便)of the female leader of a group when facing food shortage.

During drought (干旱) they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine (尿液) to make them muddy!

As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt (适应) as extraordinarily well to change as the desert elephant.

1. The underlined part in Paragraph 2 means “_______”.
A.remains in the African countries
B.drinks 120 liters of water a day
C.manages to live in desert areas
D.eats 150 kilograms of food daily
2. Desert elephants are called careful feeders because they_______.
A.rarely ruin trees
B.drink only every 3-4 days
C.search for food in large groups
D.protect food sources for their young
3. What can be inferred from the last sentence in the passage?
A.Overheating the earth can be stopped.
B.Not all animal species are so adaptable.
C.The planet will become hotter and hotter.
D.Not all animals are as smart as desert elephants.

文章大意:本文是一篇说明文。文章讲述了格里姆斯比蓝十字宠物食品银行创办的背景和原因。

【推荐1】Richard Croft had never struggled to feed his three dogs before, but when he was forced to stop working after being diagnosed with cancer, their monthly food bill was difficult to keep up with. He is one of dozens of people who have turned to the Blue Cross pet food bank in Grimsby, set up in June to help people in the area struggling to feed their pets amid the cost of living crisis.

Stocked (提供货物) entirely by donations from the local community, there is a steady stream of people stopping by to pick up food for their dogs and cats every Tuesday and Thursday. In a two-hour period last Tuesday, the food bank helped 76 animals from 32 families.

“Week on week we’re seeing more and more people. As fast as the food is coming in, it’s literally touching the shelf and going back out again,” said Cristina Pool, who runs the service alongside her fellow veterinary (兽医) nurse, Hannah Cardey.

“A lot of people come and they actually get quite emotional,” said Cardey. “Some people feel a bit embarrassed that it’s come to the point where they can’t feed their pet. For some people their pet is like their child, so they feel quite ashamed.”

The origins of the food bank started in January, when staff at the Grimsby Blue Cross animal hospital noticed an increase in emaciated (憔悴的) animals coming in for treatment who clearly were not getting the right nutrition. “There was a particular one, a really emaciated boxer dog. So she was one of the cases that made us think, there really is a need for this,” said Pool.

After first operating out of a cupboard, the food bank is now based in a small building next to the animal hospital, and the Blue Cross is rolling out the pet food bank plan nationally.

1. What information can we get about the Blue Cross pet food bank?
A.It is run by volunteers.B.It was set up in January.
C.It distributes pet food twice a week.D.It relies on partly donations from the local community.
2. How do some people feel when they get pet food?
A.Excited.B.Guilty.C.Grateful.D.Anxious.
3. What’s the main idea of Paragraph 5?
A.The cruel conditions of some pets.
B.The function of the Blue Cross pet food bank.
C.The reason for opening the Blue Cross pet food bank.
D.The present situation of the Blue Cross pet food bank.
4. What is the future of pet food bank like?
A.Uncertain.B.Promising.C.Risky.D.Upsetting.

【推荐2】The millipede (千足虫)


Forest life

    1     We enjoy watching television programs about bears, bats or monkeys. We knew a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film?

    2     A French scientist, Francois-Xavier, Joly, is studying one of them — the millipede.


The importance of leaves

When leaves begin to die in autumn, they turn from green to yellow and fall from the trees.

    3     Life in the forest needs these nutrients— without them, plants could not grow and so there would be no food for other animals.


Food on the forest floor

Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to break down than others, sometimes years. So what happens to these?     4    

More on the menu

The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types — But when they eat waste, they will eat any kind.     5    

So next time you are walking through a forest, remember that something may be having a meal right under your feet!

A.This is where the millipede can help.
B.However, not all leaves are equally rich.
C.Millipedes do amazing things in the soil in our forests.
D.Forests are amazing places, and so are the animals that live in them.
E.As they break down on the ground, nutrients are returned to the soil.
F.Many small animals that live in forests are very important for the soil.
G.This is how the millipede turns dead leaves into food for others and helps life continue.

文章大意:本文为一篇夹叙夹议。文章主要介绍了在新西兰海岸发现了一只阿德利企鹅,本属于南极洲的小企鹅,且这是记录里的第三次在新西兰发现了这种企鹅,并说明了这应该引起我们的重视,应该去了解是否是海洋的生态系统发生了变化。

【推荐3】The Adélie penguin, who has been named Pingu, was discovered by a local resident Harry Singh “looking lost” on the shores of New Zealand, over 3,000 kilometers away from its natural habitat.

“At first I thought it was a soft toy,” Singh told the BBC. “But suddenly the penguin moved his head, so I realized it was real. It didn’t move for one hour... and looked exhausted.” He then called penguin rescuers as he was concerned that it was not getting into the water, making it a potential target for any predatory (捕食性的) animals wandering on the beach.

On arriving at the scene, Thomas Stracke, who has been rehabilitating (康复) penguins on New Zealand’s South Island for the last 10 years, was shocked to find that the penguin was an Adélie — a species that lives exclusively on the Antarctic peninsula. Stracke said, “It is quite unusual since they are known only living in the Antarctic area. Fortunately, apart from being a bit starving and severely dehydrated, he was actually not too bad, so we gave him some fluids and some fish smoothie.”

It is only the third recorded incident of an Adélie penguin being found on New Zealand’s coast — the previous were in 1962 and 1993 — and although sitings remain incredibly rare, if they become more common it could be a worrying sign, say experts.

“I think if we started getting annual arrivals of Adélie penguins, we’d go actually, something’s changed in the ocean that we need to understand,” Otago University zoology professor Philip Seddon told The Guardian. “More studies will give us more understanding where penguins go, what they do, what the population trends are like — they’re going to tell us something about the health of that ocean ecosystem in general.”

Pingu has now been released into a bay on the Banks Peninsula, and it is hoped he may be able to make the journey home.

1. What happened to Pingu?
A.He was hunted by local people.B.He lost his food and looked upset.
C.He was finding a new natural habitat.D.He landed New Zealand by accident.
2. What does the author intend to do in paragraph 4?
A.Introduce a new topic to discuss.B.List numbers to prove an opinion.
C.Add some background information.D.Summarize the previous paragraphs.
3. What can be inferred from Philip’s words?
A.The number of penguins is on the decrease.
B.The health of ocean ecosystem should be concerned.
C.More studies about penguins have been undertaken.
D.Adélie penguins have built habitats in New Zealand.
4. What can be the best title of the text?
A.Unexpected Arrival of Rare PenguinB.Dangerous Situation of Adélie Penguins
C.Amazing Discovery by Local ResidentD.Magical Travel to New Zealand
