1 . 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.

2 . Dog walkers should show consideration, not just for the dog in their home or car, but also for their environment. Doing so will help keep the local area clean and pleasant, especially for people out walking their dog or taking children to the park.
A considerate dog walker will take steps to prevent their pets from producing waste wherever they want to. Dog waste is particularly unpleasant and should be avoided at all costs. Not only is it nasty to walk in a dirty area, but it is also a serious health risk. Dog fouling ( 污垢) is a criminal offence in the UK and carries a maximum fined ￡1,000 if the case goes to court (法庭). Dog walkers should always be prepared to pick up after their dog by carrying dog waste bags or even plastic carrier bags that can be used. Do not run the risk of allowing your dog to make a public area dirty by always having a steady supply of bags with you during dog walks. Carrying a single bag during a walk is not always enough, as some dogs will need to go twice or perhaps even three times during walks.
Some dog owners are not willing to admit that their pets is a challenge or troublesome. Rather than dislike the suggestions that dogs should be kept under control, you should see it as your duty to protect other dogs, children and anyone else from harm. Do know troublesome behaviors such as aggression (攻击) towards other dogs or children and make every effort to keep your dog under control. Avoid areas where you know other dogs or children will be. They can do this by showing respect for other people’s property, picking up after their dog and by keeping challenging dogs under control.

3 . Children need to be prepared for an earthquake as much as adults, if not more.
Infants and Toddlers (初学走路的儿童) For infants and toddlers, special emphasis should be placed on making their environment as safe as possible. The beds should be placed away from windows and tall bookcases that could slide or fall. A minimum of a 72-hour supply of extra water, bottles, food, juices, clothing and medications should be stored where it is most likely to be reached after an earthquake. Also keep an extra bag with these things in your car. Install bumper pads (防撞垫) to protect babies during the shaking. Install latches (闩锁) on all cupboards (not just those young children can reach) so that nothing can fall on your baby during a quake.
Preschool and School-age Children By age three or so, children can understand what an earthquake is and how to get ready for one. Take the time to explain what causes earthquakes in terms they understand. Include your children in family discussions and planning for earthquake safety. Conduct drills and review safety procedures every six months. Show children the safest places to be in each room when an earthquake hits. Also show them all possible exits from each room. Teach children what to do wherever they are during an earthquake (at school, in a tall building, outdoors). Make sure children’s emergency cards at school are up-to-date. It’s important that they know what gas smells like. Advise children to tell an adult if they smell gas after an earthquake.

4 . Tips for Green Travel with Kids
Travelling doesn’t mean letting go of all the eco-friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids.
Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn’t have nonstop flights to a certain place, check with other local airports to see if nonstop flights are available.
It’s easy when travelling to pull in to fast food restaurants for snacks.
| A．Walking is good for your health. |
| B．Try to cut back to save water and energy. |
| C．But you can pack healthy food from home. |

| E．Reusable water bottles are easy to bring along wherever you travel. |
| F．Save energy by turning off the hotel room lights when you head out for the day. |
| G．You might have to drive a bit farther, but saving on carbon emissions makes it worthwhile. |
5 . Now, Earth Day is celebrated every year on April 22. A man, called Senator Gaylord Nelson Take, was determined to change the way we treated our planet. He didn’t stop his work until he had made a difference.
In 1963, Senator Gaylord Nelson wasn’t happy with the earth’s condition. He wanted to clean up the planet and solve pollution and environmental problems. As a senator, Gaylord Nelson was someone chosen by US citizens to help make laws, so he had a lot of power. He went to John F. Kennedy, the President at the time, with his concerns. The President agreed that the planet’s environment was a serious issue, so President Kennedy went around the country on a fiveday tour to promote (宣传) the idea of cleaning up the planet. People began making small changes, but it wasn’t enough.
A few years later, Senator Nelson decided to put one day aside every year for the cause of saving the planet. On April 22,1970, the first Earth Day was celebrated; 20 million American demonstrators (示威者) took part in Earth Day activities. Since then, Earth Day has become an international holiday. People all over the world are doing something to make the earth a cleaner, better place. Today more than 500 million people in 164 countries participate (参与) in Earth Day festivities!
Then, what can you do to make a difference?
*Encourage your family to recycle on a regular basis. It is a good way to help the earth!
*Switch to energyefficient light bulbs in your house to reduce the effects of global warming.
*Every glass bottle you recycle saves enough energy to run a TV for an hour and a half, while recycling an aluminum (铝) bottle can save enough energy to run your TV for three hours!
*Turn out the lights when you leave a room — unless someone’s still there!
*Use reuseable containers for your school lunches and snacks.

6 . One day, a woman walked into a pet store to buy a bird for her Thanksgiving Day party. The guy said, “We only have one parrot. But I think you do not want it because it can talk…” The woman said happily, “That’s great. I’ve always wanted a talking bird.” So the guy said, “Since you are a nice lady, I’ll give it to you as a gift.”
And the lady went home and put the bird on her bed and walked out of the room. But as soon as she walked into the kitchen, the bird started to speak dirty words as loud as it could. The woman walked back into the room thinking, “I can’t have this at my party!” So she took the bird and put it in the fridge. A few hours later, while the woman was eating, she remembered that her bird was still in the fridge. Quickly, she opened the door and found it was shivering. Then she took out the bird at once. She said to the bird, “I’ll keep you out of there if you don’t use that language again. Do you agree with me?”
The bird nodded and asked, “Can I just ask a quick question?” The lady nodded and said, “Yes, you may.” The bird pointed at the turkey behind him and asked, “What did he do?”

7 . Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all?
To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That’s why dry deserts everywhere are almost not covered by trees or grass.
Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the cracks of the stones to grow in.
Another thing plants must have before they can grow is food.
What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

8 . Experts say that the ability of dogs to smell is one million times stronger than that of humans. With so much sniff (闻) power, it’s hardly surprising that they stick their heads out of car windows. They don’t care about the scenery. What they’re after are the smells.
When dogs put their faces into the wind, their upper lips and noses are sniffing, their eyes partly closed, and their ears folded back. It looks as if they’re enjoying themselves very much, but mainly they’re concentrating. It’s as though they’re closing down all the rest of their senses to concentrate on this one. Every dog loves to hang his head out of the window, and all dogs have an excellent sense of smell. This ability is increased when they are moving quickly, which is one reason that they take advantage of open car windows. It also probably makes them excellent hunters.
Smell is so important to dogs that they have two systems for it. One is in the nose, which consists of a huge amount of tissue (组织) with scent receptors (嗅觉感受器). This area takes up about 1/2 square inch in humans, but up to 20 square inches in some dogs. As air moves over the tissue, odor molecules (气味分子) reach the millions of scent receptors. The more air flowing there is, the better dogs smell. So they love to put their faces into the wind.
Dogs have a second system in their mouths, where a tiny pipe leads to Jacobson’s organ (犁鼻器). Its task is to catch different types of smells. Dogs depend on it to find the sources of smells.

9 .
Elephant Conservation
Country:Thailand
This is a working vacation at a wildlife centre. Anyone can become a volunteer if he/she agrees to help the elephant keepers with tasks.
Daily tasks
Collect the elephants at 6:30 a.m. Take them to look for food in the forest. Clean the enclosure. Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch satellite television.
How this vacation helps
If these elephants hadn’t been rescued, they would still be living on the streets of Bangkok. A rural environment is much better for them than an urban environment where there is lots of pollution.
Gorilla Safari
Countries:Kenya, Rwanda, Uganda
Departures:Aug.—Dec., 2—3 departures per month
Extras:gorilla permit ￡220
If you’re lucky, you’ll see lions, elephants and rhinos on safari. The highlight of the trip is the opportunity to see gorillas in the mountain forests. However, you must be in good health—if a gorilla caught a cold, it would be extremely harmful to its whole family.
How this vacation helps
There are only about 600 mountain gorillas left in the world as human activity has reduced the area where they can live. When you buy a permit, this will pay for the protection of the national park.
Polar Bear Watching
Country:Canada
Departures:sixty trips between Oct. 1—Nov. 19
Every October and November, groups of polar bears gather in Hudson Bay. As they are normally lonely creatures, this is unusual. The bears wait for the ocean to freeze so they can hunt seals, so this is the perfect opportunity to see them.
How this vacation helps
If the Arctic ice cap melts due to global warming, polar bears will be in danger. We give a share of our profits to the Polar Bears Alive Charity.
Your comment
These awesome bears get all the liquid they need from their food.

10 . As most people know, in the last few years, sandstorms have swept across many cities and areas of North China, polluting the air and disturbing daily lives of human beings. People look dirty and suffer many kinds of illnesses, such as breath difficulty. The sandstorm is such a serious problem that it has not only weakened the industrial and agricultural development of our country but also caused a lot of trouble to the living conditions of the Chinese people.
Therefore, effective measures should be taken as soon as possible to stop its happening. So how should we deal with the frightening sandstorms?
Some experts offer practical advice as follows: For one thing, more money ought to be put into tree planting and forest protection in order to keep more water on the Earth. For another, government of all countries should make laws on environment protection. For example, banning (禁止) the use of throw-away chopsticks and punishing illegal tree cutting. Scientists should also study and find ways to lower the grade of its destruction and to improve the environment. As for some schools, education about sandstorms should be spread properly and timely to make more and more people attach great importance to this problem.
How people look forward to sunny days with soft wind touching their faces now and forever! The golden days can come back so long as we try our best to protect the natural environment from today on. And the fact is that what I expect is not just a dream. There are some sweet fruits from the early efforts.
