Chris is not a traditional explorer— he usually {#blank#}1{#/blank#} (work) in an office for a large organization. However, Chris' job can be just {#blank#}2{#/blank#} exciting and dangerous as being an explorer.

    Chris is a doctor from France and he works for MSF,{#blank#}3{#/blank#} is also known as Doctors Without Borders. MSF sends its doctors all over the world {#blank#}4{#/blank#}(help) people after a war or a disaster. The organization received the Nobel Peace Prize in 1999.

    At the moment, there are over 27,000 trained doctors taking part in MSF projects and tasks. This year, more than 2300 international doctors will join {#blank#}5{#/blank#} (they) to provide medical help around the world. All kinds of doctors can volunteer for MSF. They need to be {#blank#}6{#/blank#} (prepare) to go almost anywhere and, of course, they should expect difficult conditions. When MSF accepts a doctor for a task, he has to go for {#blank#}7{#/blank#} least six months.

    When {#blank#}8{#/blank#} (ask) why he left a comfortable life and a good salary to join MSF, Chris said, “The experience I gain is a great help in my career. More {#blank#}9{#/blank#} (important), it is great to know at the end of each task that I have made a real {#blank#}10{#/blank#} (different) to people's lives.”

    Ask helpful Hannah

    Dear helpful Hannah,

    I've got a problem with my husband, Sam. He bought a smart phone a couple of months ago and he took it on our recent ski vacation to Colorado, it was a great trip except for one problem. He has a constant urge {#blank#}1{#/blank#} for next messages; he checks his phone every five minutes! He's so addicted to it that he just can't stand the idea{#blank#}2{#/blank#} there may be an important text. He can't help checking even at inappropriate times like when we are eating in a restaurant and I am talking to him! He behaves {#blank#}3{#/blank#} any small amount of boredom can make him feel the need to check his phone even when he know he shouldn't. The temptation to see {#blank#}4{#/blank#} is connecting him is just too great. When I ask him to put down the phone and stop {#blank#}5{#/blank#}  (ignore) me, he say, “In a minute.” but still checks to see if {#blank#}6{#/blank#} has posted something new on the Internet. Our life {#blank#}7{#/blank#}  (interrupted). If we go somewhere and I ask him to have the phone at home, he suffers from withdrawal symptom. May this dependency on his smart phone has become more than an everyday problem.

    I recently read an article about “nomophobia,”{#blank#}8{#/blank#} is a real illness people can't suffer from the fear of being without your phone! I am worried that Sam maybe suffering from this illness because he feels anxious if he doesn't have his phone with him, even for a short time.

Who would have thought that little devices like these could have brought so much trouble!

    Jack Ma, the chairman and founder of China's e-commerce giant Alibaba Group, took down on Google's artificial intelligence AlphaGo at the Big Data Expo{#blank#}1{#/blank#}(hold) in Guiyang, Guizhou Province, and urged Chinese enterprises not to develop such things{#blank#}2{#/blank#}AlphaGo. Chinese Go player Ke Jie, current world No. 1, has admitted defeats in his three{#blank#}3{#/blank#}(match) against computer program AlphaGo in Wuzhen, Zhejiang Province,{#blank#}4{#/blank#}led to heavy online discussions regarding the future of mankind and AI.

    “Machines must have its own special thinking and must do thins human cannot do,” Ma added,{#blank#}5{#/blank#} (believe) AI should work for humans to do useful things that human are unable to achieve, rather than just spoiling human's fun.

    But speaking for myself, I don't really care. I{#blank#}6{#/blank#}(especial) advised that many fellow enterprises should not develop such things and we can do many other useful things.”

    Ma also explained{#blank#}7{#/blank#}he didn't like AlphaGo: “Go game is{#blank#}8{#/blank#}interesting and fun thing where I can wait for my competitor{#blank#}9{#/blank#}(play) wrong and I can win. But the machine never plays wrong and it can work out the next 300 steps{#blank#}10{#/blank#}you can only think about the next three.”

    On arriving in the United States, I felt everything was different. There were many new things I had to adapt to. One thing that really {#blank#}1{#/blank#}(take) me a long time to adapt to was speaking the language.

    I remember {#blank#}2{#/blank#}(clear) that I had to struggle to learn English because I couldn't even write a short paragraph to introduce myself at the first day of my English class. The teacher asked me {#blank#}3{#/blank#}it was difficult for me. If it was, I could change to level one!

    However, I was stubborn and swore that I was going to succeed. I started to spend many {#blank#}4{#/blank#}(hour)per day, even though it was stressful, because I wanted to take advantage {#blank#}5{#/blank#}this special chance to study English in the USA.

    I felt depressed because I couldn't understand {#blank#}6{#/blank#}people were saying even though I made great efforts. However, I still kept {#blank#}7{#/blank#}(try) and never gave up.

Now, I can tell you that I have improved a lot, but sometimes it is still easy for me to get{#blank#}8{#/blank#}(confuse) if I don't know what topic people {#blank#}9{#/blank#}(talk) about. To adapt to this new language, I had to tell {#blank#}10{#/blank#}(I) that I could do it. I really believe I can!

    China successfully landed the Chang'e 4 lunar probe(月球探测器)on the far side of the moon on January 3,2019, becoming the only country in history{#blank#}1{#/blank#}(touch) the lunar surface unseen by those on Earth. The far side of the moon has been seen and mapped{#blank#}2{#/blank#}(previous) by astronauts of the Apollo missions. But it is the first time that the moon's far side{#blank#}3{#/blank#}(set) foot on by any spacecraft, and the successful landing of Chang'e 4 is seen as a major milestone in space {#blank#}4{#/blank#}(explore).

    The Chang'e 4 spacecraft consists{#blank#}5{#/blank#}two parts:a lander and a rover(巡视器). Representing China's{#blank#}6{#/blank#}(new) step in the lunar probe project of all time, it landed at 10:26 am Beijing time. Then it sent back a photo of the landing place.{#blank#}7{#/blank#}(shoot) through cameras on the probe's lander, the photo marks the world's first image taken on the surface of the far side of the moon. One of the photos published by the China National Space Administration shows the place{#blank#}8{#/blank#}Chang'e 4's rover-named Yutu 2~will be heading hours later for{#blank#}9{#/blank#}purpose of conducting further research. The name Chang'e has its roots in the Chinese goddess of the moon. In the ancient tale, Chang'e{#blank#}10{#/blank#}(fly) to the heavens and landed on the moon as her final resting place.

    Moving silently through Alibaba Group Holding Ltd's "FlyZoo" hotel, black disc-shaped robots about a metre in height deliver food and drop off fresh towels.

    The robots are part of a set of high-tech tools that Alibaba {#blank#}1{#/blank#} (say) extremely cuts the hotel's cost of human labour and removes the need for guests to interact {#blank#}2{#/blank#} other people.

    Inside the hotel, softly-lit white panelled walls bring to mind {#blank#}3{#/blank#} insides of Hollywood spaceships. Guests check in at reception desks that scan {#blank#}4{#/blank#} (they) faces, as well as passports or other ID. {#blank#}5{#/blank#} (visit) with a Chinese national ID can scan their faces using their smartphones to check in ahead of time.

    At the hotel's restaurant, taller capsule-shaped robots deliver food that guests {#blank#}6{#/blank#} (order) via the FlyZoo app while at a separate bar, a large robotic arm can mix more than 20 different types of cocktails. Facial recognition cameras add charges to the room rate {#blank#}7{#/blank#} (automatic).

    The hotel does employ humans, {#blank#}8{#/blank#} Alibaba refused to tell how many. This includes chefs and cleaners as well as reception staff, {#blank#}9{#/blank#} will assist with conventional check-in procedures for guests unwilling to have their faces {#blank#}10{#/blank#} (scan) and want to use electronic key cards.
