To make this tea, the tea trees and fruit trees     5     (plant) together. The practice, passed down from ancestors, guarantees the     6     (tea) fruity and sweet taste.

Traditionally, Biluochun is produced     7     (entire) by hand. About 1 kilogram of leaves     8     (pick) from a big tea tree produce only 0.1 kilogram of tea after processing.

Biluochun must be processed soon after. Tender tea shoots are placed in a heated iron pan and stirred (搅拌) quickly. A person needs to be particularly attentive     9     (adjust) the level of heat to judge the condition of the tea by smell. Next     10     (come) the shaping process. By stirring, shaking and rubbing the tea leaves in the pan at 100℃, they begin to dry and develop a spiral form. The entire process usually takes about 40 minutes. Every minute matters, or the tea will not taste good.

Of all the notable mountains in China, the Huangshan Mountain is probably the most famous. The fairy-land like Huangshan national park     1     (occupy) an area of 160.6 square kilometers possesses not only attractive scenery but also rich resources and diverse animal species, for     2     it has been listed as a World Natural and Cultural Heritage Site.

The absurd stones can     7     (see) almost on every peak of Huangshan Mountain. From different viewing angles, the stones look like human beings, animals or other objects.

The hot springs keep an average temperature of around 42.5℃ all year round. Taking a bath     9     a hot spring while appreciating the wonderful natural landscapes is     10     relaxing that you will get away from the tiredness after the Huangshan hiking.

The first     1     (discover) of water on the moon was made in 2009 by India’s Chandrayaan-1 mission. The team used NASA’s Moon Mineralogy Mapper instrument to     2     (final) discover water. Since then, water has been mapped from orbit in     3     (mission) like NASA’s Lunar Reconnaissance Orbiter.

China’s Chang’e5 lunar lander used its mineralogical spectrometer (矿物学光谱仪),     4     was designed to find water. It did so by     5     (determine) spectral reflectance (光谱反射率) measurements of rocks on the moon. The water was found near the Oceanus Procellarum on the moon’s near side.

The Chang’e 5 landed on the moon on December 1, 2020 with a mission to collect lunar rocks to bring back to Earth. This is China’s first ever sample (样本) return mission;however, the country has had four     6     (success) robotic tasks to the moon before the Chang’e 5.

The lander was     7     the surface for less than 48 hours before it headed back into orbit around the moon.

China is     8     third country to bring samples back from the moon, after the United States and the Soviet Union. China is working hard to launch the Chang’e 6 in 2023. The lander is meant     9     (be)a backup to the Chang’e 5, but it     10     (head) to the lunar south pole for samples.
