2、 B阅读下面短文,根据内容完成表格中所缺的信息(每空不超过3个单词)。
My name's Marly. I'm from an Inuit(因纽特人的) village in the far north of Canada. Our lives are closely connected to the natural world of the Arctic(北极).
Although we live in regular houses, we stay in temporary shelters called" igloos(冰屋)"when we go hunting. Igloos are made of snow or ice. On the one hand, they are quite warm inside and the building materials can be found everywhere. But on the other hand, they can only be kept for around 50 days.
We get our food from the nearby sea. Eating a lot of fish and meat keeps our bodies strong so that we can fight the cold. But the disadvantage is that the cold weather makes it difficult for us to grow enough vegetables and fruit.
It's completely dark here for three months of the year, which is a period called" polar night(极夜)". So, life can sometimes be boring! But the good thing is, during that time the elders tell us stories about our people. It gives us more time to be with our family and friends.
Nowadays, ships bring tourists to the Arctic. The advantage to this is that it brings more money and job opportunities, but the disadvantage is that our environment is being polluted.
One thing is for sure, though: No matter how things change, our traditions will remain an important part of our lives.

15、 机器人会控制世界吗
Are you troubled by housework, such as cleaning tables or tidying your room? A new robot is here to help! Recently, short videos of a robot called Mobile Aloha cooking at someone's home caught lots of attention online.
In the videos, we can see the robot preparing dishes on its own, from cutting vegetables to cooking eggs. It's also good at watering plants, petting cats, cleaning the floor and washing clothes. Linda, a 40-year-old housewife joked, "As long as this thing doesn't try to hurt me while I am asleep, I am in real need of it. "
Well, another video may disappoint her. Mobile Aloha carelessly broke glasses and plates, knocked into things and even burned a dish. In fact, Mobile Aloha isn't good at doing housework on its own. Instead, it learns from human actions before doing each kind of housework. When the situation changes, it can't work well without a human" teaching" it. The robot can successfully move chairs 80 percent of the time. For cooking dishes, it's only 40percent. In short, it's far from perfect.
AI robots are good at tasks such as math and playing chess, but they perform worse than a one-year-old child when it comes to simple tasks like cleaning. And it's the same for Mobile Aloha. ④For example, if its body doesn't move correctly even just with a small deviation, its arm may move too far to pick up a glass.
Well, robots are not ready to control the world yet!

D、By asking programmers for help.(2)、Which is TRUE about Mobile Aloha?A、Mobile Aloha is ready for sale. B、Mobile Aloha is popular with housewives. C、It is expensive to have Mobile Aloha do housework. D、Even kids may do cleaning better than Mobile Aloha.(3)、The underlined word "deviation" in Paragraph 4 means"____".A、difference B、adventure C、experience D、experiment(4)、Which may be the best title for the passage?A、AI— Perfect for Housework B、AI Controlling Humans C、Mobile Aloha Beats Humans D、Mobile Aloha— Cleaning or Messing up -
