【推荐3】On the morning of Nov. 24, China made history by starting the world’s first lunar return mission of the past 44 years. On that day, a Long March 5 rocket was sent into space from the Wenchang Space Launch Center in Hainan province. It’s carrying the Chang’e 5 lunar probe. The mission will last about 23 days, according to the China National Space Administration. The Chang’e 5 mission is special for several reasons.
A return mission
It’s China’s first sample return mission. This means that the Chang’e 5 probe will take back samples of the moon’s soil and rocks. The samples will return to Earth sometime in December.
The last lunar sample return mission was the former Soviet Union’s Luna 24 mission in 1976.
Larger samples
The Chang’e 5 mission plans to bring back larger samples than missions in the past. The former Soviet Union brought back 330 grams of lunar soil samples, while Chang’e 5 is aiming for 2 kilograms of lunar samples. Chang’e 5 doesn’t need a return cabin, so it only needs a small amount of fuel. This lets it carry heavier samples.
A new landing site
Chang’e 5’s lunar landing site is known as the Ocean of Storms. It’s on the near side of the moon seen from Earth. No probes have visited this site before. It’s geologically younger than the sampling sites from the US and former Soviet Union missions. The new samples will help us learn more about the moon’s history.
| A．The mission will last over three weeks. |
| B．Chang’e 5 is a carrier rocket. |
| C．The mission started 44 years ago. |
| A．Find out if there is water on the moon. |
| B．Carry soil samples from Earth to the moon. |
| C．Take back soil and rock samples from the moon. |
| A．It has a better return cabin. |
| B．It can take heavier samples back. |
| C．It can get more kinds of samples. |
| A．It is the youngest place on the moon. |
| B．Many countries have landed their probes there. |

【推荐1】There is an interesting part of your body. It is always dying, and it is replaced (更新) every 28 days. Everywhere you go, you leave very small pieces of it on the ground or the floor. It is the largest part of your body. It is your skin (皮肤).
When we think of parts of the human body, we usually think of the heart or the brain. But the skin is also a part of your body. In fact, it makes up about 15% of your body weight and covers an area of about two square meters (m2).
The skin is always replacing itself. Dead skin cells (细胞) are always falling off your body. In fact, scientists say that half of the dirt in your house is made up of dead skin. But your skin does not just make you look pretty or old. It does some very important things.
The skin protects your body. Your skin is a covering for the inside parts. It also works hard to keep your body warm or cool. Very small holes in the skin can open or close to help control body heat.
Your skin is also a “feeler” for your body. It feels touch or pain. Parts of cells that feel touch are connected to the brain. When you touch something, your brain decides what to do and then tells your muscles (肌肉). But the parts that feel pain are connected straight to muscles. If these feel sudden pain, they tell the muscles to move quickly. The muscles don’t need the brain to tell them to jump. Because of all the things the skin does, it truly is an amazing part of your body.
