We must study hard we can get good grades.
I once worked at a restaurant. One night，an elderly couple signaled（夫妇示意）to me that they were ready to order. I quickly went to them and gave them the menu.
The man began ordering but he talked stutteringly（结结巴巴地）. It was very clear that he had a speech disorder His wife told him what she wanted and the man took the ordering as a way to practise speaking. It took some time for him to order. At the same time his wife was sitting there and she looked so proud.
I had to say they touched me a lot. It just made me realize that love is about acceptance, tolerance and support（接受、宽容和支持）. His wife could have made the order and made things easier for the man, but she didn't. Instead, she supported him and was proud to see him order by himself.
I also learned that life is difficult for us most of the time. The most important is to face the problems in life and try our best to solve them.
—Sorry, I don't know. I ________ the math problem.
Do you know the whales in the sea? There are many relatives(亲属) in the whale family and they always live together with whales.
Few people know dolphins(海豚) are part of the whale family. Dolphins are not fish. They are mammals(哺乳动物). They breathe air, and they have babies and feed them with milk. Dolphins are famous for their wonderful shows. They can jump high out of the water and show turns in the air. These jumps give the dolphins time to breathe.
Porpoises(鼠海豚) are also in the whale family and are quite like dolphins. But they are different in the size and shape of the mouth. The dolphin's mouth is long and thin, but the porpoise's is short and thick. Dolphins are also more talkative than porpoises. Dolphins make sounds to talk with each other under water. But porpoises do not do this. Both of them are smart and friendly to humans.
Not all the members of the whale family are friendly. Big whales are much easier to be angry than smaller dolphins or porpoises. An angry whale can be dangerous. Perhaps this helped to create the story of Moby Dick that sank (使下沉) a ship and made all the people on it die in the sea.
