China plans to launch the Chang’e-5 probe in 2020 to bring moon samples back to Earth. The Long March-5 carrier rocket, China’s current     1     ( large) launch vehicle, will be used to send the probe into space. The second Long March-5 rocket     2     (launch) from the Wenchang Space Launch Center in the southern province of Hainan on July 2, 2017, but a malfunction happened less than six minutes after    3     ( it) liftoff. China’s space engineers have spent over two years    4     (look) for the cause of the malfunction. The third Long March-5 rocket is being transported to the Wenchang Space Launch Center    5    a new flight. The    6     (succeed) of the flight will be the key for China’s future space missions including the Chang’e-5 probe. The Chang’e-5 probe includes a lander, an orbiter, an ascender and a returner. The key of the mission will be lunar sample collection, takeoff from the moon, rendezvous and docking on lunar obit and high-speed reentry into Earth’ atmosphere. China’s current lunar program includes three phases: orbiting, landing, and returning. The first two phases have been accomplished, and    7     next step is to launch the Chang’e-5 probe     8     (collect) 2 kg of moon samples and bring them back to the earth. China is also drawing up the plan for the fourth phase of the lunar exploration program. In the fourth phase of the program, China will conduct scientific detection in the south polar region of the moon by     9     (main) using high intelligent robots, and realize long-term exploration in the complicated lunar environment. There might be some ancient craters and frozen water at the south pole of the moon,     10    is of great research value.

Falling on December 7 this year, Major Snow, also known as “Da Xue” in Chinese, is the     1     (three) solar term of winter. As its name implies, Major Snow reflects the phenomenon of precipitation,     2     (indicate) the time and intensity of snowfall.

Plum blossoms usually flower in mid-to-late December in some southern cities of China, and sometimes bloom even     3     (early). The plum blossom, along with the pine and bamboo,     4     (consider) one of the Three Friends of Winter.

In some areas, eating lamb is excellent for nourishing the body, promoting blood circulation and providing protection     5     the cold. In     6     (add), people often eat lotus (莲花) root,     7     can clear away heat in the chest and prevent dryness-heat.

During Major Snow, it is suggested that people     8     (keep) their feet clean and dry, wash and massage their feet every day     9     (stay) healthy, and try to reduce outdoor activities. Also, drinking a bowl of warm porridge in the morning is     10     excellent way to nourish the stomach.

Nature’s Lungs

We know that trees are nature’s purifier (净化器): They absorb carbon emissions (碳排放)and release oxygen. But their     1       (able) to do that changes as they age. According to Newsweek, trees     2       are at least 20 years old can absorb carbon better than younger ones and older ones. And a recent study by researchers from South Korea’s Forest Research Institute     3       (find) exactly how much carbon that each 25-year-old cherry tree can absorb: 20 pounds (9.1 kilograms) each year.

According to the study, there are     4       (current) about 1.5 million cherry trees in South Korea, which means they can take in as much as 13,650 tons of carbon each year.

This may sound like a lot,     5       it’s only the annual emissions of 6,000 cars. And it’s pretty     6       (shock) if you think about it: The annual emissions of a single-car requires 250 mature cherry trees to absorb     7       carbon.

Yet, planting trees is still considered the most effective way     8       (reduce) global warming, according to Professor Tom Crowther of the Swiss university ETH Zurich. “Forest restoration isn’t just one of our climate change     9       (solution), it’s the top one,” he told the Guardian. “What blows my mind is the scale. I thought restoration would be in the top 10, but it is much    10     (powerful) than all of the other climate change solutions proposed.”

The construction of the main structure of Xiongan railway station’s west section     1     (complete) last Friday, according to sources from the China Railway. It marks an important step in the construction of the intercity railroad     2     (link) Beijing and Xiongan New Area in North China’s Hebei Province,     3     is set to be operational by the end of this year.

With a total construction area of 475,000 square meters, the Xiongan railway station is the biggest one among the five     4     (station) along the 92.4-kilometre-long intercity railroad. The project of the railway station will make Xiongan well     5     (connect) with the central, southern, northwestern, southwestern and northeastern parts of China.

In a master development plan for Xiongan New Area published in 2018, the Chinese government described the new area     6     having national significance following the Shenzhen Special Economic Zone and Shanghai Pudong New Area. About 100 kilometers southwest of Beijing, Xiongan New Area, known as China’s “city of the future”, has been designed     7     (become) a zone for innovation, a digital city and an     8     (energy) and business-friendly area. According to the plan, by the middle of the century, Xiongan New Area, will become a significant part of the world-class Beijing-Tianjin-Hebei city group,     9     (effective) performing Beijing’s non-capital functions and providing     10     Chinese solution to big city malaise (不适).

Hardly had I received your letter when I couldn’t help     1    (write) back to you. You truly need correct ways to read successfully. I’m glad to tell you     2    (me) suggestions.

First of all, you’d choose the books     3    are neither too difficult     4    too easy for you. Secondly, the books should not only interest you but also benefit you.

Best wishes! If there’s anything I can do     10    you in future, please don’t hesitate to tell me.
