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.

Dear Peter,

How times flies! It had been almost a year since you left China to Sweden. During your home stay at my home, we had such wonderful time that it seemed as if everything had been happened yesterday. I have been long to hear all about you and missing you so much. Fortunate, I was selected as one of the student representative to pay a visit to your school. The visit will last on July 7th to 20th. And as a super soccer fan, I’d really love to visit our local soccer club.

I can’t wait for the day to come where I can see you.

Yours,

Li Hua

Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock 1. Here is how to make one.

● 2. In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.

? Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 3. That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

? Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 4.

? Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record. 5. If not, take another look at other methods you could try.

A. Get a sleep specialist.

B. Find the right motivation.

C. A better plan for sleep can help.

D. And consider setting a second alarm.

E. If the steps you take are working, keep it up.

F. Stick to your set bedtime and wake-up time, no matter the day.

G. Reconsider the 15 minutes you spend in line at the café to get coffee.
