Return to the moon
It might not be long until humans uncover the secrets of the far side of the moon. China’s Chang’e 4 robotic probe (探测器), which is set to become the first probe to land on the moon’s far side, was launched successfully on Dec 8, Xinhua reported.
The moon rotates (自转) at the same speed that it orbits (绕…运行) Earth. Therefore, the same side of the moon always faces Earth. The far side of the moon is the side that we cannot see. We don’t know much about it so far.
However, the far side of the moon is an ideal (理想的) place for scientific research(研究). It is exposed (暴露) to solar winds that may have formed unique minerals (矿物质) and other resources. And since the far side is less affected by Earth’s gravity, scientists can make clearer observations of deep space from there, according to China Daily.
But it is hard to land on the far side of the moon. Spacecraft that land there cannot receive any radio signals(信号) from Earth. To solve this problem, China launched a relay satellite (中继卫星) called Queqiao into space in May. Through Queqiao, scientists can control and operate Chang’e 4 and make sure it will land in a specific(特定的) area.
The probe’s travel time is also important. Chang’e 4 is expected to land on the moon on Jan 2, China Daily reported. It will travel through space for more than 20 days before landing. This is longer than Chang’e 3, which was in space for about 12 days before landing.
The travel time was changed because scientists want Chang’e 4 to land on the moon when it is daytime. This way, the spacecraft’s solar panels ( 太 阳 能 板 ) can receive energy from the sun and allow the probe to start working. A single day on the moon is about 28 days on Earth. Therefore, Chang’e 4 will keep orbiting the moon before landing as it waits for daytime, according to Sun Zezhou, chief designer of Chang’e 4.
Did you know? Chang’e 4 took some plant seeds and eggs to the moon. It was hoped that Chang’e 4 was able to do experiments with them. These were the first biological experiments to take place on the moon.

Food is a major（主要的）of every culture. After all, everyone needs to eat! But each country has its own traditions on what people eat and when.
Egypt
Egyptians commonly start the day with a drink, sometimes going with bread. Breakfast can be eaten any time after this but before the day’s main meal. In the past, this main meal was served at around 3:00 p.m. But now people work longer hours and eat when they get home at around 6:00 p.m. Dinner parties are held later, around 9:00 p.m.
Most Egyptian meals include bread or ice, cooked vegetables and beans or meat.
France
France is known for its fine cooking, and its people take food seriously. Most eat three meals a day at fixed times and never snack between meals. Breakfast is a light meal of bread and coffee. They eat lunch at around 1:00 p.m. and a dinner with multiple courses after 8:00 p.m.
The French consider eating a social activity. Eating alone is hard to see, and eating while doing something else is unheard-of. The French take time to enjoy their meals and visitors should do the same.
Brazil
Like the French, Brazilians usually eat a light breakfast. Lunch, the largest meal of the day, usually consists of meat, rice, potatoes, beans and vegetables. Between 6:00 p.m. and 8:00 p.m., people enjoy a smaller meal with their families.
Brazilians don’t mind eating a hurried or light meal and sometimes buy food from street carts (手推车). But they always finish eating before walking away.
The United States
American’s ancestors came from many countries, so American eating habits differ. Some take time to prepare and eat a hot breakfast. Others take a bagel (面包圈) while rushing out the door or just skip breakfast. For lunch, most Americans eat a sandwich or leftovers. Traditionally, families got together for a large evening meal around 6:00, but now busy schedules force many families to eat in turns. American restaurant servings tend to be huge. But you don’t have to finish them; taking leftovers home is common.
