| A. Careful biological research B. The information of global warming C. Solution to the terrifying result D. Greater danger of extinction E. Examples of species in danger of extinction F. A shocking report |
The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane (沼气) and nitrous oxide. These gases, called “greenhouse gases”, prevent the heat of the sun from leaving the earth’s upper atmosphere and this makes the earth warmer.
A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.
More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plants and animals from extinction.
The scientists studied some regions of the world with a very rich biology. These regions were Europe, Australia, Central and South America and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in greater danger of extinction.
The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100 of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in this region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.
Most Americans would find it hard to imagine what life would look like without cars. . The polluted air becomes poisonous and dangerous to health.
. That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of the car engine by something else. . Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down..
Although cars have led us to a better life, they have also brought us new problems.
| A．Inventors are now working on steam cars as well as electric cars |
| B．Americans know cars very well. |
| C．However, some have realized the serious problems of the air pollution that is caused by cars. |
| D．One way to get rid of the polluted air is to build a car that does not pollute. |
E. However, the number of vehicles has continued to increase in recent years.
F. Americans won’t live without cars!
G. Thus the problem of air pollution would become less important than that of unemployment.

When your pet is sick, you know it needs medication. But pets, like babies, don't know the pill you want them to take will help them. Here are some tips to help get your pet to take liquid medicine.
If the answer is yes, then your easiest path is to mix it with canned food. First give your hungry pet a small amount of canned food without the medication. It's important that the pet nibbles (一点一点地吃) at the food and sees that there's nothing wrong.
Next, while the pet is still hungry, mix the medication in a small amount of food and present it. Repeat as necessary to get the entire dose (剂量)down. If the pet decides not to finish the meal, the dose will be wasted.
If the chemist says the medication cannot be taken with food, you need a syringe (注射器) or a dropper (滴管) to get the liquid down your pet's throat. Keep a cheerful tone in your voice so the pet doesn't sense your stress or hesitation. Position your pet where it cannot run away, perhaps having a dog sit with his back against a wall or chair ---- or a cat on your lap.
Use your other hand to insert the syringe or dropper between the cheek and back teeth. Slowly squeeze the medication so the pet won't choke. Try to keep your pet's mouth closed for about 30 seconds until you see it has swallowed. If your pet is being obstinate (倔强的) , stroke (抚摸) its throat gently or blow on the face.
Be sure you end the process with praise and perhaps a treat so your pet will not associate medication with a bad experience.
| A．Before you call your pet in, be sure to have the medication and any other materials you’ll need ready. |
| B．Once the pet is in position, use one hand to gently open the pet's mouth from above, tilting(倾斜) back the head slightly. |
| C．Ask the vet(兽医) if the liquid medication can be given with food. |
| D．You should know the reason why the pet refuses to take medicine. |
E. Never mix the medication with the full meal.
F. They just know it smells funny and they don't want it.
G. Don’t force your pet to swallow all the medicine

●Does failure really exist ?
If you believe you have failed, then you have. If you believe you don’t have the ability to succeed, then you don’t. The moment you decide to give up or stop working toward your goals, failure is born.
●
Most people give themselves an out without even realizing it. They are willing to work hard on reaching their goals, but only until the going gets too rough or their energy dies down. Don’t do that! Never quit, never admit failure, and never lose heart.
●Don’t believe in a clear finish line for goals.
It’s a good idea to set a general timeline, but remember that something will be beyond your control. If you lock yourself into a given timeline, you might make yourself feel like a failure! Instead, get a general idea of when you’d like your goal to be completed. Then take it one day at a time and focus on making progress instead of reaching the finish line in as little time as possible.
●Be sure that you don’t see difficulties as failures.
Difficulties mean only one thing: it’s not time for your goal to be completed yet. That’s it! It doesn’t mean you failed; it doesn’t mean you’re weak; it doesn’t mean you’ll never achieve your goals. You’ve got to keep moving forward and find a way over, around, or through the difficulties.
| A．Never give up on yourself. |
| B．Failure only exists in your own mind! |
| C．That’s exactly how failure makes us feel. |
| D．It simply means you have not done enough yet. |
E. You can never say exactly when your goal will be reached.
F. Instead, make up your mind to make your goal happen, no matter what!
G. Work hard towards your goal, and you will be likely to get good results.
