We always think that it's OK for us to leave our plants home during our vacation as plants won't scream like pets, right?

    A recent study done by a group of scientists at the Tel Aviv University has discovered that some plants will scream when they are under stress.

    The research was carried out on tomato plants and tobacco plants by cutting their stems (茎) and depriving (剥夺) them of water. A microphone was placed 10cm away from them. When their stems were cut, the plants started "screaming" between 20 and 100 kilohertz, and the scientists guess that this scream is probably meant to warn other plants nearby.

    When the tomato plants' stems were cut, 25 ultrasonic (超声的) pain sounds were recorded in an hour, and at the same time, 15 ultrasonic pain sounds were recorded from the tobacco plants. When they were deprived of water, the tomato plants recorded even more pain sounds with 35 pain sounds in an hour while the tobacco plants recorded about 11 pain sounds.

    The plants also acted differently to different kinds of stresses. For example, the tobacco plants gave out a stronger "scream" when they were deprived of water than when their stems were cut. But plants that were in no immediate (立刻的) danger gave out less than one ultrasonic sound per hour.

    The group of scientists said that plants are not as quiet as we had always thought, but in fact their voices are so high-pitched that we just can't hear them.

    Last year, another study has found out that plants feel pain when they are touched or hurt and they will give off a terrible smell.

Dear Jenny, 

I am very busy on Friday. At 8:00 I have math. It is not fun. The teacher says it is useful, but I think it is difficult. Then at 9:00 I have science. It is difficult but interesting. At 10:00 I have history. After that, I have P. E. at 11:00. It is easy and fun. Lunch is from 12:00 to 1:00, and after that we have Chinese. It is my favorite subject. Our Chinese teacher, Mrs. Wang, is great fun. My classes finish at 1:50, but after that I have an art lesson for two hours. It is really relaxing!

How about you? When are your classes? What is your favorite subject? 

Your friend, 

Yu Mei 

According to a research, more than 130 billion pounds of uneaten food go to waste in Laura's country each year. That is about 30% of the yearly food supply(供应). It is a sad fact, especially when you consider how many families and homeless people are in hunger.

When Laura saw her school dining hall throw away food that was not eaten at all every day, she came up with an idea. She started a project to help her school dining hall to give away uneaten food to homeless shelters(庇护所) in her community. In the past three years, the same project has spread to other schools and some fast food restaurants throughout the city. The project is called Feed & Find, and has already fed thousands of people in her city.

How does it work? Through an app, Feed & Find matches local homeless shelters with school dining halls and restaurants that have uneaten food to provide. When dining halls or restaurants have uneaten food left, they can use the app to share the information about the food. A truck driver working for the project is then sent to pick it up and take it to a shelter.

Pretty cool, right? It's not surprising that people in other cities have got in touch with Laura, hoping that she could help develop similar projects for their communities.

Some people, however, have concerns about the safety of the uneaten food. They think such food may not be clean enough. Still, this

project is a clever way to help solve the problem of food waste and it helps those in need.
