1 . Everyone complains. Even if you argue that you are the happiest person in the world, you still complain sometimes. Sometimes you complain without even realizing it, but rarely is it ever helpful.     1     Here are some tips to stop complaining and give up the negative thoughts.

    2    

When you find yourself thinking or saying a negative comment about something or someone, stop and force yourself to say something positive instead. Seek the help of a cheerful friend to change you when you complain and help you to see the positive in the situation.

Make a list of things you are grateful for.

You often complain about the things you don’t have without noticing those things you already have. Be grateful for what you have in your life because you are lucky simply for being yourselves.     3    

Learn to adapt to the changes.

There are many things you can’t change.     4     Always find the positive side of each situation, regardless of however difficult the situation is. With parents’ and friends’ support, you can survive any life changes.

Allow yourself to vent (发泄) your feelings every once in a while.

Constantly ignoring negative thoughts could add up. If you are really going through a rough time, don’t be afraid to share your feelings with a close friend or family member or see a therapist.

Find what makes you happy.

    5     Maybe it is time to make the hard decision to move on to another job or career. Uncover what your biggest complaints are about and see if you can change the situation to make you happy. Choose happiness, focus on the positive, and be kind always!

6 . Pearl Moss looked out her front window in Bethel Park, Pennsyvania. She was instantly _________. A major snowstorm over the weekend had dropped_________ a foot of snow in her driveway, and there was more on the way. She was recovering from shoulder surgery and didn’t have family members nearby who could _________ to dig her out.

A few hours later, there was a _________ on her door. Moss looked out and was surprised to see two teenage boys with shovels (铁铲). David Shelpman and Aidan Campbell _________ in the same neighborhood as Moss and are on the football team at Bethel Park High School. Head Coach Brian DeLallo had emailed his team members on Sunday to _________ them that their Monday’s workout in the school gym wasn’t going to _________. DeLallo also instructed them to find an elderly or disabled neighbor and shovel their driveway. Shelpman and about 40 other team members took their _________ seriously.

Helping elderly and disabled residents to dig out after snowstorms is a Bethel Park _________ that goes back two decades. In Bethel Park, community support of the football team is strong. “Our games are always well __________ so giving back is the right response,” DeLallo said.

Pearl Moss said she’s grateful for the teens adding that if they hadn’t shown up, she probably would have been stuck in her house for a while.

7 . NASA’s spacecraft Dart hit an asteroid (小行星) 11.3 million kilometers away at a speed, changing the asteroid’s orbit and lowered its cycle period by 15 minutes, the space organization announced on Monday.

Some said the move shows the world might now be able to prevent asteroids—the kind that made the dinosaurs extinct—from hitting the Earth. The asteroid that was controlled belonged to a double-asteroid system. It had a 160-meter diameter while the other asteroid’s diameter is over 500 meters. The bigger asteroid can be compared to the one that ended the dinosaur era 67 million years ago. A hit from an asteroid that size can cause unimaginable destruction.

However, it is too early to assert that the world has gained the ability to prevent asteroids from hitting us. The asteroid that was controlled was only 160 meters in size. Its cycle period was changed, without changing its orbit significantly. It is still not clear if the orbit of a much larger asteroid headed toward the Earth can be changed successfully.

In brief, NASA’s success in changing the course of a harmful asteroid is definitely praiseworthy, but much more needs to be done before we can say the world’s security from some unpredictable asteroid is guaranteed.

It should be noted that changing the orbit of an asteroid involves more than just sending an object into space and commanding it to hit the asteroid. While it is hard enough to hit an asteroid, it is even more difficult to lock onto one in the first place. It means having the ability to observe approaching asteroids, measuring their respective speeds, and deciding which ones might pose a danger to the Earth.

Therefore, there’s more to Dart hitting the asteroid than meets the eye. And these are key areas where global scientists need to work harder in the future.

Discovering yourself plays an important role in inspiring your confidence. By doing so, you could know     1     you are weak in. And you may also realize you’re quite a great person     2     great strengths. So when you’re in a hard situation, you will believe in yourself and spend the most difficult time with confidence. Otherwise, you may give up and then lose everything. Therefore, the ability     3     (trust) yourself will decide your future a lot.
