Sometimes I really doubt whether there is love between my parents. Every day they are verybusy trying to make money for my schooling. One day, my mother was sewing a quilt (缝被子). I silently sat beside her.

    " Mum, is there 1 between you and dad?" I asked in a very low voice.

    With surprise in her eyes, she2her work for a while. Then she said, "Susan, look at this thread (线). It can hardly be seen, 3it's really there. It makes the quilt strong. If life is a quilt, love should be a thread. Love is inside. "

    I couldn't understand her4 the next spring. At that time, my father suddenly got sick seriously. My mother had to stay with him in the hospital for a month.

    After they were back, my mother helped my father walk5on the country road every day. They were so kind to each other and it seemed they were the happiest couple.

    After two months my father6couldn't walk by himself.

" Dad, how are you feeling now?" I asked him one day. "Susan, don't7me, " he said, "I just like walking with your mum. I like this kind of life. "8his eyes, I knew he loves my mother deeply.

     Now I understand that love is just a thread in the quilt of our 9. Love is inside , making life10and warm.

    A little girl was born in America. She was1ill when she was 4. The illness left the girl a useless(无用的)2. She couldn't walk like other children, 3she had to wear a leg brace(支架). 4 , she had a good mother. Her mother5her to the doctor every week. So at 9, she could walk 6 the leg brace, like other children.

    At 13, the girl 7 running She took part in every race at school, but every time she was the 8 to reach the finishing line. Everyone knew that it was really9for her to run a common person. The girl kept practicing. One day, she started to win. Then she had a10. She wanted to be the world's greatest woman11.

    Later the girl went to university and met Ed Temple, a coach(教练). She asked Temple to be her coach and he12. Ed Temple trained the girl so13that she went to the Olympic Games in 1960. Guess14? She won two gold medals in the 400-meter and 200-meter races. With a good term, she also wen the 400-meter relay race(接力赛).

    The girl was Wilma Rudolph—one of the15woman in the world.

Future astronauts could travel with emotional support robots

    To help astronauts of the future survive (幸免于) the mental (精神的) challenges that come with staying in space for quite a long time, space travelers‟ tasks could soon be accompanied(陪伴) by AI-powered, empathetic (有同理心的, 同感的) robotic helpers.

    Not only does space travel present astronauts with lots of physical stresses, spending months or years in such a physically demanding (要求高的) place with limited space and the same people can also raise many mental tests as well. According to MIT Technology Review, scientists are working to alleviate astronauts from some of the latter challenges by creating "an AI assistant that's able to feel human emotion and respond (做出反应) with empathy."

    While such a technology would prove itself useful by being able to predict the needs of the

crew members in space and "intervene (干预) if their mental health is in danger," it has the potential to be life-saving when humans choose to explore beyond Earth's gravitational field (引力场) and towards deep space.

    Though astronauts currently on the International Space Station have an intelligent robot to interact with called CIMON, it is short of proper emotional intelligence according to NASA CTO Tom Soderstrom. As a result, a team at the organization's Jet Propulsion Laboratory is working on a more complex (复杂的) emotional support companion that can control a spacecraft's functioning in addition to tracking the crew members‟ behaviours.

    Right now in the lab, an AI-equipped robot called Henry the Helper can be found walking around the grounds assisting visitors who appear confused or lost based on their facial expression. Two more emotionally intelligent robots are expected to be introduced later this year, one of which is said to be able to take part in conversations more complex than giving navigation(导航) assistance.

    The team's final goal is to make a companion named Fiona the Future a reality, an emotionally intelligent cross-platform system. Fiona, if all goes according to the JPL's plans, will help keep astronauts of the future stay mentally fit as they start their journeys to deep space.

Hi, everybody. Here we're in front of the South Gate. Go straight on, and you'll find the Panda House. Pandas are cute. They like to eat bamboo and lie down all day long. Every year, lots of visitors come here to see them. 

Walk along the road. To the north of the Panda House, you'll find the lions. Lions are the kings of the animal world. Remember that they're dangerous. Never go near them. 

Turn left, and to the west of the Lions' Area, you'll find the World of Birds. Birds make beautiful sounds when they sing. To the north of the World of Birds is the Monkeys' Forest. Monkeys are clever and funny. They jump around and make people laugh. 

Then turn right, and to the east of the Monkeys' Forest, you'll see the giraffes(长颈鹿). They're quite tall. Their long necks help them eat the leaves from trees. 

Northeast of the giraffes there's a bridge. Cross the bridge, and you'll see the elephants. Their large ears are like open fans.
