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.

My Best Friend

Hello, I'm Xia Ming. I have a best friend.

 If you are looking for a simple place to stay for a few nights, a capsule(胶囊) hotel might be a good choice. Providing small rooms and just a few basic services, these hotels can help people save lots of money.

 What do the rooms in capsule hotels look like? The rooms are usually the size of a bed. They are very small, but they have enough space for you to sit up on the bed. Rooms in capsule hotels are usually side by side and on top of one another. So, if you are staying on the top level, you have to use a ladder to climb into your room. There are also curtains( 帘布) for you when you' re sleeping. Although there's little you can do inside your room apart from ( 除了……还 ) sleeping, capsule hotels usually provide other services. Shared bathrooms and dining areas are available (可提供的) for you to use.

 The first capsule hotel appeared in Osaka, Japan in 1979. Many Japanese loved the idea, so more capsule hotels opened all over the country. From there, capsule hotels spread to several other countries such as India and Iceland. China has also seen a rise in the number of such hotels in recent years. And they are quite popular with young people.

 Many experts(专家) believe capsule hotels will become more popular as time goes by. What do you think?

 Welcome to life in the future! You get up in the morning and look into the mirror. You' ve recently had a new anti-aging(抗衰老) treatment, so you look like a 30-year-old. And many people your age could live to be 120 now, so--at 60--you' re not old at all.

 Science has also found amazing ways to keep people healthy. Nanotechnology(纳米技术) can help cure(治愈) many illnesses, including cancer(癌症). And if any part of your body is unhealthy, you can"grow" a new one in a laboratory(实验室).

As you get dressed, you say to your shirt, "Turn red." It becomes red. In 2045, "smart" clothes contain nanoparticles(纳米粒子) that carry electricity. So you can program clothes to change colors or patterns.

 On the way to the kitchen, you want to call a friend. Your cell phone is by the window because it gets its energy from the sun. But you don't need to pick up the phone. You can just touch your jacket sleeve(袖子) to make the call.

 It's breakfast time. You reach for the milk, but a voice says, "Don't drink that!" Your fridge knows the milk is old and tells the supermarket to replace it. Ten minutes later, it's delivered by a drone(无人机).

 As you leave for work, the lights turn off by themselves. Your home goes into"sleep" mode to save energv. In 2045, cars drive themsclves, so you just tell your driverless car where you want to go.

 Will all this come true? Perhaps the future is much closer than we think.
