2 . China has named the nation’s first Mars rover (火星车) Zhu Rong. For all of us, Zhu Rong is a well-suited name.

In an ancient Chinese story, Zhu Rong had the face of a man and the body of an animal. H rode on two dragons.

When he had a big fight with Gong Gong, the god of water, Zhu Rong won. But after the fight, the human world came into complete darkness. Then he brought fire from heaven to the world.

“Zhu Rong is regarded as the earliest god of fire in traditional Chinese culture,” a space official said. “The first Mars rover was named Zhu Rong. The name symbolizes light and hope for space exploration in our country, and means to guide humans to continue exploration.”

After leaving the earth last summer, Zhu Rong circled Mars for several months and landed on it in May. In recent years, our country has sent up the world’s first quantum satellite (量子卫星), and Chang’e-4 has made a soft landing on the moon. We have made great progress in space technology and will soon start building our own space station.

3 . The Lunar Calendar (农历) Modern Chinese use the solar calendar (阳历) as English people do. But at the same time, they use their own lunar calendar. Each lunar year is given the name of one of these animals: the rat, the ox, the tiger, the hare, the dragon, the snake, the horse, the goat, the monkey, the chicken, the dog and the pig. This list lasts for 12 years and then starts again.

Each Chinese month starts on the day of the new moon. And the full moon comes on the 15th day of the month. The New Year always starts between January 21 and February 20. On the last day of the lunar year, there is a big family dinner. All members of the family except married daughters try to be present at this meal, even they have to travel many miles to reach the home of their parents. Old quarrels are forgotten, and everybody is happy. After the dinner, the children keep awake to welcome the New Year.

The New Year celebrations last for 15 days, from the new moon to the full moon. On the first day , children and unmarried people go to visit their elders.

Recent research examined data on the sports habits and mental health of 11,235 kids aged 9 to 13. Parents reported on several aspects of the children’s mental health by    1     (fill) out a form known as the Child Behavior Checklist. The researchers looked for any associations between the mental health data and the kids’ sports habits, while also accounting for other    2     (factor) that might impact mental health.

In line    3     the researchers’ expectations, the study showed that kids     4     (involve) in team sports were less likely to have signs of emotional, social and attention problems. The researchers also expected playing individual sports to be associated with    5     (few) mental health problems than playing no sports. However, they found that children    6     only played individual sports were likely to have greater mental health problems than those who did not play sports at all.

These findings add to a growing body of evidence ( 证据) that playing team sports is     7     (positive) associated with mental health for children     8     youth. The researchers suggest that longitudinal ( 纵向的) observations are needed     9     (investigate) any causal ( 因果的) relationships between sport    10     (participate) and mental health.

Pearl Harbor is a U.S.naval base near Honolulu, Hawaii, which was     1    scene of a destructive surprise attack by Japanese forces     2    December 7, 1941.Just before 8 a.m.that Sunday morning, hundreds of Japanese fighter planes attacked on the base,     3    they managed to destroy or damage nearly 20 American naval ships,     4    (include) eight battleships, and over 180 airplanes.More than 2,000 Americans     5    (die)in the attack, including common people, and another 1,000 people     6    (wound).The day after the attack, President Franklin D.Roosevelt asked Congress     7     (declare) war on Japan. 

During the Pearl Harbor Attack in 1941 the USS Arizona sank with a     8     (lose) of more than 1,000 men.A white concrete and steel structure now spans the remains of the     9    (sink) ship, which was dedicated as a     10    (nation) memorial on May 30, 1962.Present facilities at Pearl Harbor include a naval shipyard, supply centre, and submarine base.

The world’s first ship with     1    intelligent unmanned system was launched in Guangzhou. The ship     2     the world’s first scientific research ship     3    can work by remote control in open waters. It will provide an     4    tool for China     5    out marine scientific research and develop the marine economy.

The equipment on the ship is highly localized (本十化的), because the key parts have all been     6     developed by Chinese scientists. The ship has a     7    of 88. 5 meters, width of 14 meters and a depth of 6. 1 meters. With a broad deck, the ship can carry a dozen different observation instruments. Construction of the ship     8    on July 20, 2022, and it is expected to be put into use by the end of this year. In the future, the use o the ship will be     9    great importance for getting real-time ocean observation information,     10    the level of ocean observation.
