How to Improve Your English
Define your learning objectives early: what do you want to learn and why? Make learning a habit. 1. It is much better to study (or read, or listen to English news, and so on) for 10 minutes each day than to study for 2 hours once a week.
Choose your materials well. You will need reading, grammar, writing, speaking and listening materials—beginners can use a basiclevel English guide, and then move on to an advancedlevel English guide. 2. It will make learning more enjoyable—thus more effective.
Vary your learning routine. It is best to do different things each day to help keep the various relationships between each area active. 3.
4. Learning English together can be very encouraging. You can find friends to speak English on the Internet.
Relate grammar to practical usage. Grammar by itself does not help you use the language. You should practice what you are learning by employing it actively.
Move your mouth! Understanding something doesn't mean that the muscles of your mouth can produce the sounds. 5. It may seem strange, but it is very effective.
Be patient with yourself. Remember that learning is a process—speaking a language well takes time. It is not a computer that is either on or off!
A. The Internet is the most exciting, unlimited English resource.
B. Try to learn something every day.
C. Practice speaking what you are learning aloud.
D. In other words, don't just study grammar.
E. Find your own interests.
F. Choose articles that relate to what you are fond of.
G. Find friends to study and speak with.
When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked .It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, then he asked, “Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it. “That's just for you，” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feel hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.” Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.
