Anyone who has had a long-term disease knows that recovering at home can be lonely. This can be{#blank#}1{#/blank#}(especial) true of children. They may feel {#blank#}2{#/blank#} (leave) out. Now, these children may have a high-tech friend to help fed less alone. A small robot may help children who are recovering from long-term illnesses. The robot like human beings takes their place at school. And their school friends must help carry the robot between classes and place the robot on their desks.

    Through the robot, a child can hear his or her teachers and friends. He or she can also attend classes from wherever they are recovering—whether at home{#blank#}3{#/blank#}from a hospital bed. Dolva, one of the scientists who {#blank#}4{#/blank#}(be) concentrating on developing the robot, explains{#blank#}5{#/blank#}the robot AVI works. She says from home, the child uses a tablet or phone to start the robot,{#blank#}6{#/blank#} (use) the same device, he or she can control the robot's movements. Inside the robots there is a small computer linked{#blank#}7{#/blank#}a 4G network. The robot is {#blank#}8{#/blank#}(equip) with speakers, microphones and cameras,{#blank#}9{#/blank#}makes communicating{#blank#}10{#/blank#}(easy). So it's the eyes and the cars and the voices at school. Hopefully AVI will help some children feel less lonely while they are absent from class.

    For some time, I had been thinking that I wanted to do something to make strangers smile. I decided that I {#blank#}1{#/blank#} (leave) small notes around shops and other public places with positive sayings or kind words for strangers{#blank#}2{#/blank#} (find).

    A friend on Facebook posted that she had received a lot of beautiful paper from an artist friend and was wondering what to do with it. I told her about my idea, and she {#blank#}3{#/blank#} (immediate) said that this must be what her paper was meant for.

    So two friends on opposite {#blank#}4{#/blank#} (side) of the world started leaving these random notes of kindness. I leave my notes without {#blank#}5{#/blank#}(expect) any particular result. It doesn't matter whether they are read{#blank#}6{#/blank#}thrown away. The main thing is that I did this act.

    I now carry around a notebook in {#blank#}7{#/blank#} I write down lovely and inspiring phrases that I find. And I buy packs of Post­ its to write notes on whenever I see {#blank#}8{#/blank#} opportunity to make a stranger smile. I only leave the notes when I am feeling in a {#blank#}9{#/blank#} (happily) mood, as I don't want to pass any negative energy on to someone else.

    I sign them all{#blank#}10{#/blank#} (say) that this note is left for you by a stranger to make you smile. Then, I add a heart.

    For more than six million American children, coming home after school means coming home to an empty house. All of them have something {#blank#}1{#/blank#} common. They spend part of each day alone. They are called latchkey children, who look after{#blank#}2{#/blank#} (them) while their parents work.

    Lynette Smith was once the headmaster of a school. She said, “We had a school rule against{#blank#}3{#/blank#} (wear) jewelry. A lot of kids had chains around their necks with keys fastened. I was{#blank#}4{#/blank#} (constant) telling them to put them inside their shirts. There were so many keys. It never came to my mind {#blank#}5{#/blank#} they meant.” Slowly, she learned they were house keys.

    She and her husband began talking to the children. Fear is the {#blank#}6{#/blank#} (big) problem faced by children at home alone. One in each three latchkey children were scared. Many had nightmares and were worried about their own {#blank#}7{#/blank#} (safe).

    The most common way latchkey children deal with their fears is by hiding. It might be in a shower still, under a bed{#blank#}8{#/blank#} in a closet. The second is TV. They'll often play it at high volume{#blank#}9{#/blank#}Smiths learned it's hard to get statistics on latchkey children. Most parents are unwilling {#blank#}10{#/blank#} (admit) they leave their children alone.

    Thanksgiving was drawing near and I was feeling sad about being separated from my family in Indiana.

    Would I have to prepare a traditional Thanksgiving dinner by {#blank#}1{#/blank#}(my)?

That night at Dubya's Restaurant, which was my favorite place to dine, I chatted with Dubya, the {#blank#}2{#/blank#} (own) of the restaurant. “It's too bad that this place won't be open {#blank#}3{#/blank#} Thanksgiving, or I could just come here.” I said.

    “Why not join my family for the holiday?” he said in a warm voice. I knew Dubya and his wife well, but I didn't think we were close enough {#blank#}4{#/blank#} (share) Thanksgiving dinner. I was sure he was joking. But Dubya soon handed me a note on which directions to their house and their phone number {#blank#}5{#/blank#} (write).

    And two days later, I reached Dubya's house. As{#blank#}6{#/blank#} (expect), the food was great but the company（陪伴）was even {#blank#}7{#/blank#} (good). I truly felt I belonged there.

    Of course, I wrote them {#blank#}8{#/blank#} thank-you letter the next week, but I couldn't really put into words {#blank#}9{#/blank#}that Thanksgiving dinner invitation had meant to me. I've never forgotten their {#blank#}10{#/blank#} (kind) and that very special Thanksgiving.

    During the past ten years, traditional Chinese medicine (TCM) has been gaining {#blank#}1{#/blank#} (popular) across the world. This style of health care has spread to 183 countries. Up to now, approximately 100 international agreements {#blank#}2{#/blank#} (sign) with Chinese government on TCM cooperation. One of the reasons for such a growing trend is probably due to the increase of {#blank#}3{#/blank#} (science) research into TCM. Since Tu Youyou, a Chinese scientist was awarded Nobel Prize for her discovery of the drug qinghaosu, TCM has become even more{#blank#}4{#/blank#}(globe) famous. While quite a few {#blank#}5{#/blank#} (explain) have been given to support TCM theories, it is still faced with the challenge in {#blank#}6{#/blank#} (prove) to the public that it has certain effects when used in medical treatment. That's to say, it is significant in {#blank#}7{#/blank#} long run for TCM to team up with Western medicine. Scientists hold the belief {#blank#}8{#/blank#} using the collective knowledge, rather than regarding the two approaches {#blank#}9{#/blank#} being in competition is where the potential for its enormous effects {#blank#}10{#/blank#}(lie) in.
