1970 was "World Conservation Year". The UN wanted everyone to know that the world was in danger - they hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only remain 860. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives here. We can't live without these things. If it continues like this, we shall destroy ourselves.

       What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record called NO ONE'S GOING TO CHANGE OUR WORLD. It was made by the Beatles and other singers. The money from it will help to conserve wild animals.

One of the things to be learnt in a foreign language is guessing. You guess what kind of thing to come when listening to someone talking. People do this all the time in their own language, so it is necessary(必要的) to do this in a foreign language, too. Here are some examples.

1. " What's thematter?""I went to a party last night, so I…"

2. "I feel so tired these days. "" I think you'd better..."

3. " Of course, she never stops talking. She is one of the most..."

You can see from the above three examples that the context(上下文) helps a lot in understanding what is being talked about. So" guessing " is very important in understanding English, especially(尤其) spoken English.

People at some time feel life is stagnating (停滞的) and think life is not very exciting.

Then, they need to do something to improve the quality of life. Life is what people make it. So, read the list of things to do now to make life better and more enjoyable.

Help Others

One of the best ways of creating positivity is to help other people. Those who often help others do feel good about themselves, and other people will benefit from involvement (参与). They can offer help in a shop or in the old people's home.

Take Up a Hobby

Hobbies are great because they can give people something different to do. When someone leads a boring life, it is great to have something to think about. It will take him into another world. They love to read, spending time just sitting with a book and losing themselves in an imaginary world.

Learn a Skill

A great way to learn a skill is to join a class. Not only will they learn a skill, but also they will make new friends in the class. Whether they are going to learn to cook or play a musical instrument, there is always a class near their homes.

It happens every spring. Flowers come out everywhere on the same day. But how do plants "know" when to flower?

For years, it has been a difficult question for scientists. But a US research group may have finally answered it—the secret lies in a protein(蛋白质)called FKF1. This helps plants to know when the days become long and when they get short. Then they can tell the seasons(季节)are changing.

Researchers found the FKF1 protein when they were studying a plant called Arabidopsis. It is sensitive(敏感的)to sunlight, and can be made active by sunlight.

Plants produce this protein every day in the late afternoon all year. If there is no light at this time, for example, in winter when the sun goes down early, the protein won't be active. But when spring comes and the days get longer, the FKF1 protein can be made active by day light and the plants "know" it is time to flower. " If there is light in the late afternoon, plants will know that the days are getting longer and that it is the best time for flowers to come out,"explained Takato Imaizumi, leader of study. But when conditions are poor for growing, such as during autumn or winter when the weather is cold and days are short, plants won' t flower.

Although researchers have only studied how the FKF1 protein works in the Arabidopsis, they believe that it is the same with many other plants, including crops such as rice and wheat.

"If we can control when flowers come out, we might be able to increase crop production," Imaizumi said.

What is the perfect(完美的)life like? And what should we do to reach that?

We all hope to be healthy, to have much energy(能量)and to live healthily and happily. Today, with the quick development of medical science, the quality of our health can be better and the life will be much healthier and more beautiful! It's reported that people with excellent health habits are far healthier, have more energy, and live longer and better than people who have poor health habits. 

It's really important for us to enjoy excellent relationships with the people we like and respect(尊敬), and they like, love and respect us in turn. Fully 85% of your happiness will be decided by the quality of your relationships at each time, and in each place, of your life. How well you get along with people and how much they like, love and respect you, have more effect on quality of your life than perhaps any other reason. 

It's essential to do work that we enjoy, to do it well, and to be paid for it. You want to be able to get and keep the job you want, to be paid more. You want to make the very most that is possible for you at each area(领域), whatever you do. 

It's a great feeling to achieve financial independence(经济独立). You want to reach the point in life where you have enough money so you never have any financial worries. You want to be really free of them.
