阅读表达,阅读下面短文,根据短文后的要求答题。

    The Clean Your Plate Campaign was set up by nongovernmental organizations, which urged people to save food by not wasting anything on the dining table and finish all the food on the plate. The campaign, launched on weibo, was soon joined by millions of netizens across China in order to control food wastage.

    A study show that the grain that people waste every year in China is about 50 million tons , enough to feed about 200 million people for one year.

    Nearly 750 restaurants in Beijing have joined the Clean Your Plate campaign against wasting food by offering smaller dishes, half dishes and assorting dishes to reduce waste, and encourage customers to take leftovers home.

    Now (1)         (share) the empty dishes after dinner is popular with many youngers, and they are proud of it.

    ⑵ Our government is trying its best to put an end to food wastage, and is taking the lead to save food.

根据短文理解,选择正确答案。

    Do you want to live a happier, less stressful(有压力的) life? Try laughing for no reason at all. That's how millions of people start their day at Laughter(笑声) Clubs around the world and many doctors now think that having a good laugh might be one of the best ways to stay healthy.

    The first Laughter Club was started in Mumbai, India, in 1995 by Dr. Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr. Kataria. “Everyone is naturally good at laughing—it's the common language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 in the world.

    Many doctors are also interested in the effects(效果) of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.

    So what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest, I wasn't interested in laughing with a group of strangers, and I was worried about looking silly. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha” while looking at each other. However, our bodies can't tell the difference between real laughter and unreal laughter, so they still produce the same healthy effects.

    Surprisingly, it works! After ten minutes everybody in the room was laughing for real and some people just couldn't stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you're under stress, then start laughing. You might be very pleased with the results.

    One day, a woman walked into a pet store to buy a bird for her Thanksgiving Day party. The guy said, “We only have one parrot. But I think you do not want it because it can talk…”

    The woman said happily, “That's great. I've always wanted a talking bird.”

    So the guy said, “Since you are a nice lady, I'll give it to you as a gift.”

    And the lady went home and put the bird on her bed and walked out of the room. But as soon as she walked into the kitchen, the bird started to speak dirty words as loud as it could. The woman walked back into the room thinking, “I can't have this at my party!” So she took the bird and put it in the fridge.

    A few hours later, while the woman was eating, she remembered that her bird was still in the fridge. Quickly, she opened the door and found it was shivering. Then she took out the bird at once. She said to the bird, “I'll keep you out of there if you don't use that language again. Do you agree with me?”

    The bird nodded and asked, “Can I just ask a quick question?” The lady nodded and said, “Yes, you may.”

    The bird pointed at the turkey behind him and asked, “What did he do?”

阅读下面短文,从短文后所给的A、B、C、D四个选项中选出能填入相应空白处的最佳选项。

    Mr. Black was over fifty years old. He sometimes made some mistakes in his work, and he lost his work. So he had 1 time every day to do something. Then he often met his old friends under a big tree. They had drinks there and talked 2 anything they liked.

    One day, some old men were sitting together again and talking about young people in this world. They all agreed that the old people were 3 than young people. Then one of the old 4 said that young men were stronger than old men. 5 of them agreed that this was true, 6 Mr. Black didn't. He said, “No. I am as strong now as when I was a young man.” His friends were surprised 7 what he said. “Well,” said Mr. Black, “Near my house there is a big stone. When I was a young man, I used 8 to move it, but I couldn't because I was not 9. I am an old man now, and when I try to move it, I still 10. So, I am as strong as when I was young.”
