It’s a sound you will probably never hear, a sickened tree sending out a distress signal. However, a team of scientists at the U.S. Department of Agriculture’s Forest Service has recently heard the cries, and they think some insects also hear the trees and are drawn to them like vultures attracted to a dying animal.
Researchers hypothesized that these sounds – actually vibrations produced by the surface of plants – were caused by a severe lack of moisture. They fastened electronic sensors to the bark of drought-stricken trees and clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50–500 kilohertz range. (The unaided human ear can detect no more than 20 kilohertz.) They experimented on red oak, maple, white pine, aspen and birch and found that all make slightly different sounds. With practice, scientists could identify the species of tree by its characteristic sound signature.
The scientists surmise that the vibrations are created when the water columns inside tubes that run the length of the trees are cracked, a result of too little water flowing through them. These fractured columns send out distinctive vibration patterns. Because some insects communicate at ultrasonic frequencies, they may pick up the trees’ vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also have a different smell from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Writing an Essay (Về Béo phì)
Prompt:
More people are overweight. What are the causes and what are the solutions?
Nowadays, many people are overweight. This is a big problem. There are two main reasons for this.
Ngày nay, nhiều người bị thừa cân. Đây là một vấn đề lớn. Có hai lý do chính cho việc này.
First, people eat too much unhealthy food. Fast food like burgers and pizza has a lot of fat and sugar. This makes people gain weight quickly. Second, people are lazy and do not exercise enough. Many people sit at computers all day and watch TV at night.
Thứ nhất, mọi người ăn quá nhiều thực phẩm không lành mạnh. Đồ ăn nhanh như bánh mì kẹp thịt và pizza có nhiều chất béo và đường. Điều này làm cho mọi người tăng cân nhanh chóng. Thứ hai, mọi người lười biếng và không tập thể dục đủ. Nhiều người ngồi máy tính cả ngày và xem TV vào ban đêm.
To solve this problem, we need to change our habits. People should eat more vegetables and fruits instead of fast food. Also, everyone should do exercise every day, like walking, running, or playing sports. Schools should teach children about healthy food.
Để giải quyết vấn đề này, chúng ta cần thay đổi thói quen. Mọi người nên ăn nhiều rau và trái cây thay vì đồ ăn nhanh. Ngoài ra, mọi người nên tập thể dục mỗi ngày, như đi bộ, chạy hoặc chơi thể thao. Trường học nên dạy trẻ em về thực phẩm lành mạnh.
In conclusion, obesity is bad for health. If we eat well and exercise more, we will be healthier.
Tóm lại, béo phì có hại cho sức khỏe. Nếu chúng ta ăn uống tốt và tập thể dục nhiều hơn, chúng ta sẽ khỏe mạnh hơn.
