Although men and women have been growing crops for thousands of years, they have not always had enough to eat. Even today, many people in the world go hungry, and even die of hunger. If we are to grow enough for everybody, we have to grow more crops and better crops.

Plants need the right food in order to grow. In particular, they need three chemical substances (物质) in the soil: nitrogen (氮), phosphorus (磷) and potassium (钾). They also need smaller amounts of other chemical substances like calcium. If there is too little of any of these substances in the soil, plants can’t grow well.

When a plant grows, it takes up these basic substances from the soil and builds them into itself. If we remove the plant from the soil and use it for food, we are taking some of these substances away, and this means that future plants will find less of them in the soil. In time, the soil would become too poor for plants to grow in it at all.

To prevent this  we must put basic substances back. One way of doing this is putting manure (肥料) on the soil. This contains the remains of plants that have been eaten, and, if we add it to the soil, we are returning some of the basic substances. In Europe and in Japan, manure from animals has for long been used in this way. Unfortunately much of the animal waste in India is used as fuel because there is not enough wood to burn. This means there is less manure for the crops.

Even when we use manure, we can not put back into the soil more of the basic substances than have been taken out. Often the soil does not have enough of them in the first place, and so we must provide extra supplies. We can use chemical fertilizers (化肥). Experiments in India have shown that, if we use a fertilizer containing a mixture of nitrogen and phosphorus, we get half as much rice again from the crops on any one piece of land.

             Break Your Bad Mood

Having one of those days or weeks when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster often within a day or two.

Walk it off

Exercise is the most popular bad-mood buster. A person who’s in a bad mood his low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercise can do wonders towards changing that bad mood.

Tune it out

Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.

Give yourself a pep talk

Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper-the pessimistic(悲观的)messages you’ve been giving yourself and then give optimistic answers. (“I still don’t have a job.” Vs “I have two interviews next week.”)

Reduce your stress

Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing(想像), all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to be against distress(痛苦)is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.

Avoid things that won’t improve your mood.

TV may not help much: You need to increase your energy level and stimulate your mind something that TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. A better choice? Research shows that carbohydrates, such as potatoes and pasta(意大利面食),produce a calming effect on people who have a desire for them.

Mountain lions live in mountainous areas of the western United States. Lately, however, people have reported seeing them in quiet neighborhoods all across the country! Usually considered shy and seldom seen, these lions are becoming more noticeable. In addition, the lions appear to be moving east. They were even reported in the suburbs of Boston, Philadelphia, and Chicago.

It seems certain that these “Kings of the mountains” are moving. Why? Scientists are not sure. Some think that as the mountain lion population increases in the west, younger wild cats are leaving the area. These cats are searching for new homes and new places for food.

“The young males are looking for new homes,” says Lynn Sadler, who is the director of the Mountain Lion Foundation in Sacramento, Calif. “People tend to create too many barriers, such as buildings, fences, roads, and noise. As the mountain lions seek new places and food and water sources, these barriers get in their way.”

The sightings(亲眼目睹) have made people increasingly watchful (警惕的). Sometimes the “mountain lions” that people report seeing turn out to be large dogs or even house cats. But at least a few of the meetings have been real. The building of new roads, the growing of suburbs and the growing popularity of outdoor activities are all increasing the chances that people in various parts of the country may meet up with a mountain lion.

Because many people are concerned about the reappearance of the American lion, an expert outlined some ways they can avoid attracting the wild cats: Never leave pets or pet food outside; properly care for farm animals; and plan public land use to enable the lions to move safely from one place to another.

“To be fair,” says the expert, “mountain lions are trying to regain their homes. They were here first. Now we need to find ways we can live together.”

After an earthquake or any similar disaster, parents and teachers need to help children overcome the effects of this frightening and sometimes devastating experience. Psychologists say that if children go through a disturbing event before the age of ten, they are three times as likely to suffer psychological problems as so teenagers. After a disaster children may become easily upset, shy, aggressive, or afraid of wind, rain, noises, or darkness. They may have trouble letting go of their parents and resist going to school or daycare. Some children may even feel guilty thinking that they somehow caused the disaster through their bad behavior.  Because of such common reactions, parents and others should begin as soon after the event as possible helping these children. 

Some suggestions include talking to the children about what happened, letting the children express their own feelings, spending extra time with them doing activities together and reassuring them that you love them and won't leave them. For some children expressing themselves through drawing pictures or writing can be useful. Do everything possible to help children get back to a normal routine; however, don't be afraid to "spoil" these children for a while after the disaster.  Let them have extra privileges and more attention than usual.  Encourage the children to grieve after a loss. It should be OK for them to cry. Caring families and friends can do much to heal children victims of disasters.

 There was a time when I thought my dad I didn’t   36   him ever saying the words “I love you.” It seemed to me his only purpose in life was to say “  37  ”to anything I wanted to do, including getting a  38  . Some parents bought their kids cars when they got their driver’s licenses,   39  my dad---he said that I’d have to get a job and buy my own.

So that’s what I did. I got a job at a very nice restaurant and   40  every penny I could. And when I had enough to buy my car, I   41  ! The day I brought that car home, my dad was the first one I wanted to show it  42  to. “Look, dad, a car of my own. If you ever want a ride, I’ll only  43  you five dollars.” I offered with a smile. “I see,” was all he said.

One day, there was something wrong with my father’s truck. So he needed a  44  to work.

The sun wasn’t even up when we left the house,    45  it was already getting warm out. It was going to be a   46  day. As I dropped my dad off, I  47  him, dressed in his work clothes, getting his  48  from the trunk(车尾箱)of my car. Watching his sun-weathered face, and even from a distance I could tell there were   49   lines than I ever remembered being there before. I realized how hard my dad worked for his family. My father is a cement finisher(水泥修整工).

In that instant, it  50  to me that he actually got down on his hands and knees to sweat over hot concrete to make a living for his family. And he did this   51  ,no matter how hot it got. Never, not once, had I heard him   52  about it. To him, we were “worth” it. And never once did he “charge” us for it.

When he closed the truck, his tools set off to the side, he walked over to my window to  53  me five dollars. I rolled down the window and said, “Good-bye, dad. Keep your five dollars. It’s  54  me. Don’t work too hard. I love you.”

His eyes met mine, then glanced away in the direction of his waiting tools, he cleared his  55   and said, “Oh, and…me, too.”
