1 . Safe and Easy Workouts for Seniors
As you get older, it’s important to remain active and not to forget your health. There are plenty of all-time best exercises for weight loss, but not all are perfect for older individuals hoping to break a sweat.
You might believe that certain workouts, like pushups (俯卧撑), are only for the young. In fact, they can be changed to best suit someone’s desired difficulty level.
Overhead arm raises can benefit seniors with joint (关节) pain. Using a weighted object such as a bottle of water, position yourself shoulder-width apart. With your shoulders back and arms lifted to 90 degrees, breathe out as you lift the bottles over your head and breathe in as you lower your arms.
Endurance workouts increase your breathing and get your heart pumping. Dancing can improve the health of your heart and lungs and keep you healthy as you perform daily tasks.

2 . My body hit the water with a pounding and I suddenly felt afraid that terrible things could happen. Water gushed（涌出）through my mouth and left its salty taste. My feet touched the ground as I attempted to float back up to the surface. I could see the speed boats in the distance and I started to panic.
I saw something gray from a distance coming closer and closer. As it approached me, I realized that it was not a good one-it was a SHARK! Its fin（鳍）was moving closer and I attempted to swim as fast and as far away from it as possible. My heart beat faster and faster as my body got all stiff（僵硬的）. I looked behind me and saw the huge sharp teeth pointing directly at me. As I turned away, I heard jaws shut with a mighty bite! The shark turned away and left me alone.
I looked at my feet and saw bright red blood flow into the water. I cleaned it with some water and a thought went into my mind-sharks love blood, and that was not good for me. I knew more fins were surrounding me from every direction. I was stuck in the middle of the ocean, surrounded by about ten sharks and they were all heading for me.
They all stared at me with their white sharp teeth sticking out, ready to attack. Slower and slower they got ready to bite. Just then I heard an engine heading my way and I saw a speed boat pushing some heavy waves away. As it came closer, I saw a tall man driving it. The engine roared in my ears and it began to scare the sharks away.
As they swam away, I began to make my way back to the shore. The boat sped towards me and I slowly climbed on it. With relief we headed back towards the shore.

4 . An unmanned Chinese spacecraft left the earth on a trip to the planet Mars on Thursday. The launch （发射）marks the start of one of China's most important space explorations. China's national space agency launched the spacecraft called Tianwen-1 from the Wenchang Spacecraft Launch Center on Hainan Island.
The name Tianwen means “Questions to Heaven” in Chinese. The spacecraft took off on China's largest carrier rocket, the Long March 5, and about 36 minutes later, the spacecraft, including an orbiter（轨道飞行器）and a rover（漫游车），was sent into the Earth-Mars orbit. It is expected to reach the orbit of the red planet next February. Tianwen-1 will finish three scientific goals—orbiting the red planet, landing on the Mars and sending a rover to the landing site.
Tianwen-1 carries several scientific instruments to observe the planet's atmosphere and surface. It will do a series of scientific researches on the planet's soil, geological structure, environment, atmosphere and water. Besides its daily work of exploring the surface of Mars for 90 days, it will also report back to the earth about its experiences on the red planet, which is millions of miles away. According to experts, discovering signs of life will be its first and most important scientific goal.
Tianwen-1's successful landing will make China the second nation to place a spacecraft on Mars. The United States has landed eight vehicles on Mars since 1976. China will be the first to successfully orbit, land and place a vehicle in the same mission. This is China's first independent mission to Mars. The task in 2011 failed when a Russian rocket carrying a Chinese orbiter had problems after launch, and was unable to escape the Earth orbit. Last year, China's Chang e-4 spacecraft became the first to make a landing on the far side of the moon.
