Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.

Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.

The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.

The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is total amount of carbon stored in land plants.

The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.

Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用). That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.

Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.

All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.

Which of the following is in charge of the study?

A. The space agency NASA of the US.

B. The Department of Energy of the US.

C. Ramakrishna Nemani in Missoula.

D. Ranga Myneni in Massachusetts.

What’s the main cause of the plant growth put forward by the study?

A. Growth in population.

B. Regional features.

C. Seasonal variation.

D. Weather conditions

Why do scientists believe that reduced cloud cover has led to the plant growth in the Amazon area?

A. Because plants could take in more sunlight.

B. Because plants could get more rainfall.

C. Because plants could enjoy cooler air.

D. Because plants suffer less from natural disasters.

Which of the following descriptions about the years from 1982 to 1999 is TRUE?

A. It was the warmest on record.

B. Rainfall decreased little by little.

C. World population grew by 25%.

D. Stored carbon increased by 6%.

When you are little, the whole world feels like a big playground. I was living in Conyers, Georgia the summer it all happened. I was a second grader, but my best friend Stephanie was only in the first grade. Both of our parents were at work and most of the time they let us go our own way.

It was a hot afternoon and we decided to have an adventure in Stephanie’s basement. As I opened the basement door, before us lay the biggest room, full of amazing things like guns, dolls, and old clothes. I ran downstairs, and spotted red steel can. It was paint. I looked beyond it and there lay even more paint in bright colors like purple, orange, blue and green.

“Stephanie, I just found us a project for the day. Get some paintbrushes. We are fixing to paint.” She screamed with excitement as I told her of my secret plans and immediately we got to work. We gathered all the brushes we could find and moved all of our materials to my yard. There on the road in front of my house, we painted bit stripes (条纹) of colors across the pavement (人行道). Stripe by stripe, our colors turned into a beautiful rainbow. It was fantastic!

The sun was starting to sink. I saw a car in the distance and jumped up as I recognized the car. It was my mother. I couldn’t wait to show her my masterpiece. The car pulled slowly into the driveway and from the look on my mother’s face, I could tell that I was in deep trouble.

My mother shut the car door and walked towards me. Her eyes glaring, she shouted, “What in the world were you thinking? I understood when you made castles out of leaves, and climbed the neighbors’ trees, but this! Come inside right now!” I stood there glaring hack at her for a minute, angry because she had insulted (侮辱) my art.

“Now go clean it up!” Mother and I began cleaning the road. Tears ran down my cheeks as I saw my beautiful rainbow turn into black cement.

Though years have now passed, I still wonder where my rainbow has gone. I wonder if, maybe when I get older, I can find my rainbow and never have to brush it away. I guess we all need sort of rainbow to brighten our lives from time to time and to keep our hopes and dreams colorful.

“Indeed”George Washington wrote in his diary in 1785, “some kind of fly,or bug,had begun to eat the leaves before I left home.” But the father of America was not the father of bug.When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the Enlish were soon to stop using the bugs in their language, leaving it to be the Americans to call a bug a bug in the nineteenth and twentieth centuries.
The American bug could also be a person, referring to someone who was crazy about a particular activity.Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs and the like.
Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burlar alarm, from which comes the expression to bug, that is, “to install(安装) an alarm”. Now it means a small piece of equipment that people use for listening secretly to others’ conversations.Since the 1840s,to bug has long meant “to cheat”,and since the 1994s it has been annoying.
We also know the bug as a flaw n a computer program or other design.That meaning dates back to the time of Tomas Edison.In 1878 he explained bugs as “little problems and difficulties” that required months of stdy and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering′a bug′ in his invented record player.”
