Mulch(护盖物;护根层)is important to farmers.Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.Mulch not only protects the soil against wind and water damage.It also helps keep the soil from getting too dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds, from growing.
Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water.Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.
The United States Department of Agriculture says it is easy to find organic mulch materials.Cut-up leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants.Mulch from newspapers works well in controlling weeds.
The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil.As a result, mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.

Several years ago, my parents, my wife, my son and I ate at one of those restaurants where the menu is written on a blackboard.After a wonderful dinner, the waiter set the check in the middle of the table.That’s when it happened:my father did not reach for the check.
Conversation continued.Finally I realized that I should pick up the check!After hundreds of restaurant meals with my parents, after a lifetime of thinking of my father as the one with dollars, it had all changed.I reached for the check, and my view of myself suddenly changed.I was an adult.I was no longer a kid.
Some people mark off(区分)their lives in years, I measure mine in small events.I didn’t become a young man at a particular age, like 16, but rather when a kid who wandered in the streets called me “mister.” These events in my life are called “milestones”(里程碑)
There have been other milestones.The cops(policemen)of my youth always seemed big, even huge, and of course they were older than I was.Then one day they were suddenly realized that all the football players in the game I was watching were younger than I was.They were just big kids.With that milestone gone was the dream that someday, maybe I, too, could be a football player.Without ever having reached the hill, I was over it.
I never thought that I would fall asleep in front of the TV set as my father did.Now it’s what I do best.I never thought that I would go to the beach and not swim, yet I spent all of August at the shore and never once went into the ocean.I never thought that I would appreciate opera, but now the combination of voice and orchestra attract me.I never thought that I would prefer to stay home in the evenings, but now I find myself passing up parties.I used to think that people who watched birds were strange, but this summer I fond myself watching them, and maybe I’ll get a book on the subject.I feel a strong desire for a religious belief that I never thought I’d want, feel close to my ancestors(祖先)long gone, and echo my father in arguments with my son.I still lose…
One day I bought a house.One day-what a day!–I became a father, and not too long after that I picked up the check for my own father.I thought then it was a milestone for me.One day, when I was a little older, I realized it was one for him, too, another milestone.

Our boat floated on, between walls of forest too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains.Nowhere did we find a place where we could have landed:where the jungle did not actually spread right down into the river, banks of soft mud prevented us going ashore.In any case, what would we have sailed by landing?The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way.So we stayed in the boat, hoping we reached the sea, a friendly fisherman would pick us up and take us to civilization.
We lived on fish, caught with home-made net of string(we had no hooks), and fruits and nuts we could pick up out of the water.As we had no fire, we had to eat everything, including the fish, raw I had never tasted raw fish before, and I must say I did not much enjoy the experience; perhaps sea fish which do not live in the mud are less tasteless.After eating my raw fish, I lay back and dreamed of such things as fried chicken and rice, and ice-cream.In the never-ending damp heat of the jungle, ice-cream was a particularly frequent dream.
As for water, there was a choice:we could drink the muddy river water, or die of thirst.We drank the water.Men who had just escaped what had appeared to be certain death lose all worries about such small things as diseases caused by dirty water.In fact, none of us suffered from any illness as a result.
One day we passed another village, but fortunately nobody saw us.We did not wish to risk being taken prisoners a second time:we might not be so lucky to escape in a stolen boat again.
