Global warming is when the earth heats up，the temperature rises.It happens when greenhouse gases—carbon dioxide，water vapor，nitrous oxide(二氧化氮)，and methane(沼气) trap heat and light from the sun in the earth’s atmosphere，which increases the temperature.This is like when heat is trapped in a car.On a very hot day，the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car，by going through the windows，but it can’t get back out.Once the light is inside the car，it is trapped and the heat builds up，just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere，but it can’t get out.As a result，the temperature rises.

Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it，the earth would be freezing，or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day，especially during the summer，it would be burning because the sun would be up with no atmosphere to filter(过滤) it，so people，plants，and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the earth can get unusually warmer，and many plants，animals，and people will die.They would die because there would be less food (plants like corn，wheat，and other vegetables and fruits)．This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat，but it would also limit the food that animals have.Gradually，people，plants，and animals would all die of hunger.

People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.

Another thing that people are doing is being more careful about leaving things turned on like the television，computer，and the lights.A lot of people are taking time away from the television，and instead，they are spending more time outdoors.This helps our planet out a lot.Now，more people are even riding buses，walking to school，and riding their bikes to lower the amount of greenhouse gases in the air.

Planting trees and recycling also help.If you recycle，less trash goes to the dump，and less trash gets burned.As a result，there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming，kids can do just as much.

1.By the example given in Paragraph 1，the author wants to ________.

A．explain how greenhouse gases work

B．show his feeling in a car in hot summer

C．tell us cars are causes of greenhouse gases

D．say that there are greenhouse gases in every car

2.The underlined word “it” in Paragraph 2 refers to “________”．

A．light　                                 B．heat

C．temperature　                             D．greenhouse effect

3.What is the main idea of Paragraph 3?

A．If there is greenhouse effect，all the plants will die.

B．Human beings are likely to disappear from the earth.

C．Crops can’t take the heat if there is greenhouse effect.

D．Although greenhouse effect is necessary，too much of it causes us to die.

4.What will the author most probably discuss in the paragraph that follows?

A．Why cars and buses pollute the air a lot.

B．What kids can do to help stop global warming.

C．What global warming is doing to the environment.

D．Who should be responsible for the environmental problems.

When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.

That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.

Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today's vessels (船)can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines (多钩长线) would have been more filled with fish. Some individuals would therefore not have been caught, since no baited hooks (带饵钩)would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now。

Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline". The idea is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield （产量）that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels。. Most fisheries are well below that, which is a bad way to do business.

1.The extinction of large prehistoric animals is noted to suggest that____.

A.large animals were easily hurt in the changing environment

B.small species survived as large animals disappeared

C.large sea animals may face the same threat today

D.slow-growing fish outlive fast-growing ones

2.By saying these figures are conservative , Dr. Worm means that____ .

A.fishing technology has improved rapidly

B.the catch-sizes are actually smaller than recorded

C.the marine biomass has suffered a greater loss

D.the data collected so far are out of date

3.Dr. Myers and other researchers hold that____ .

A.people should look for a baseline that can't work for a longer time

B.fisheries should keep the yield below 50% of the biomass

C.the ocean biomass should restore its original level

D.people should adjust the fishing baseline to changing situation

4.The writer seems to be mainly concerned with most fisheries’____ .

A.biomass level B.management efficiency

C.catch-size limits D.technological application

The best tool needed for survival in the event you get lost when you travel is your skill of advanced planning. You must expect the unexpected and plan accordingly. Even if you are going out for just a few hours, pack enough essentials that you can stay hydrated (体内水分), fueled and prepared for any type of weather. Your essentials should include at least:

• More than enough food and water for the activity you plan.

• A compass that you know how to use. You may want a GPS device, but those sometimes do not receive a signal or the battery fails. Cell phones also likely will not work because of a lack of signal.

• Appropriate maps. Study the terrain (地形) and your planned route. Know where you are going and how you will return.

• Comfortable hiking boots, clothes that you can wear depending on the weather conditions and additional socks in case the ones you arc wearing get wet.

• A blanket, flashlight, matches kept in a water-resistant container, and other items that will help you survive overnight if necessary.

• Cheek with the local forest office for special warnings, such as fires in the area, bear sightings, flooding, trail or road closures, etc.

It’s also important that once you have planned your outing, tell someone. Give them exact details of where you are going, the trail you plan to follow, when you will return, the vehicle you are driving (and where you plan to park) and how many people will go with you—do not go alone.

If you do become lost, your most important tool is keeping a positive mental attitude.

1.What docs Paragraph 1 mainly tell us?

A. Getting lost outdoors is common in life.

B. Surviving in the wild is really a tough thing.

C. Hope for the best, but prepare for the worst.

D. Advanced planning can prevent future troubles.

2.What probably is continued with the text?

A. The means as to traveling around.

B. The story of the author having a tour.

C. The ups on how to be positive when in trouble.

D. The details of how to reach for rescue.

3.Where docs the text probably originate from?

A. A sports magazine.　　 B. A tourist guide.

C. A grocery list.　　 D. A science instruction.
