The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:
1. Get a reusable water bottle
Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.
2. Eat less meat
You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.
3. Switch to energy-efficient light bulbs
Most households use standard incandescent (白炽的) bulbs. But compact fluorescent (荧光的) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.
4. Buy organic and local food
Did you know that only 1 percent of pesticides (杀虫剂) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.
5. Recycle your electronics
Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (有毒的) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.
72. The readers of this passage are called on to ______.
A. help reduce global warming B. use water in a wise way C. donate money for charity D. keep a balanced diet
73. What is an advantage of CFLs according to the passage?
A. They use more energy but produce more light. B. They can last longer so don't need to be replaced often. C. They cost less than standard incandescent bulbs. D. They are as energy-efficient as incandescent bulbs.
74. Which of the following figures is correct according to the passage?
A. Every year an American buys 63 plastic water bottles on average. B. Eating meat one day less a week helps cut environment costs. C. 99 of the pesticides used on crops is effective in practice. D. Electronics account for half of poisonous heavy metals on the earth.
75. Which can be the best title for this passage?
A. Why is the earth getting warmer? B. What can we do about pollution? C. How can you lead a greener life? D. Who is to blame for global warming?

Like human beings, dogs may catch cold because of cold weather, wet conditions or can also get it from other sick dogs. If a dog has a running nose and watery eyes, coughs or sneezes （打喷嚏）, then it is quite probable that the dog has caught cold.
A dog's cold can get over after a few days without treatment but it totally depends upon the owner to treat it with medications or improve its immune power （免疫力） to get rid of the cold naturally. Following are some of the things you can do if your dog gets a cold.
You can improve its immune power by giving it proper nutrient diet. Healthy food can really do wonders. Try to give it food which is either suggested by the vet（兽医） or is healthy for your pet. Increase the intake of food which is rich in vitamins A, C and E.
Keep your dog warm. The best place for your dog in winter is inside your house. Do not keep your dog outside when it is cold and wet. At home you can also keep the dog warm with the help of carpets. This will make him comfortable and help him to recover fast.
Increase the fluid（流质） intake as it helps a lot. Water can be the best choice but you can also add broth （肉汤）in water which will give your dog strength. Warm water will make your dog more comfortable and will also keep the dog away from the respiratory infections（呼吸道感染）.
Steam treatment is considered to be effective in getting rid of cold. It makes the nasal（鼻的） passage wet, which helps proper breathing. Just fill your bathroom with steam and leave your dog inside the bathroom for 15 minutes. Do it nearly 2 to 3 times a day and you will see your dog recovering.
These are some of the things you can do to help your dog recover from cold. However, if you are not able to find any improvement in its health, then turn to the vet for help immediately. Take your dog for regular checkups so as to avoid complications（并发症）.
67．From the first paragraph we know about __________.
A．causes and symptoms（症状）of cold in dogs
B．characteristics of sick dogs
C．the similarities between dogs and human beings
D．the difficulty in keeping a dog as a pet
68．When your dog catches cold, you should feed it on _______.
A．its favorite food B．the suggested food by the vet
C．some meat and water D．food rich in vitamin B
69．When a dog catches cold, it is wrong to ________.
A．keep it inside during cold and wet weather B．let it eat too much solid food
C．leave it inside the bathroom full of steam D．keep it sleeping on rugs at home
70．It can be learnt from the text that _________.
A．a dog’s cold can always disappear naturally
B．it’s quite easy to make a sick dog recover from cold
C．treating a dog’s cold sometimes needs a vet’s help
