We often praise the world of science. It explains the world and makes our lives easier with technology. One of the most exciting fields in science is artificial intelligence (人工智能，AI). This is an area where scientists are working on creating machines that think like humans.
However，one of the most famous scientists has a very dark warning for us about this type of technology.
“The development of full artificial intelligence could lead to the end of the human race,” said Professor Stephen Hawking to the BBC.
Hawking is a well-known British Physicist and writer of bestselling science book A Brief History of Time. This warning came from a serious disease called ALS; he needs an AI computer to communicate. The computer learns how Hawking thinks and suggests the words he may want to use next.
This is a basic type of AI, which is very useful, yet Hawking fears the possibility of creating technology that can match or go beyond human intelligence. And it’s easy to imagine how terrible things may be. Many TV shows and films display big, killer machines that are far cleverer than us. “Humans, who are limited by slow biological evolution(进化), couldn’t compete, ” said Hawking.
But not every scientist is pessimistic(悲观的)about AI technology. “I believe we will remain in charge of（掌控) the technology. “ The potential(潜力)of it to solve many of the world problems will be realized.” In what direction do you think AI is going? Should we be hopeful or fearful?
1.Which of the following is TRUE about AI？
A. The technology is not very popular now.
B. Scientists haven’t controlled the technology.
C. It is now much smarter than humans.
D. It makes our lives easier.
2.The writer took Hawking as an example to ____________.
A. explain how AI has helped us
B. show the great hidden use of AI
C. show AI has already become part of our life
D. suggest that AI become dangerous for humans
3.What would be the best title for this passage?
A. AI: a friend or an enemy?
B. The development of AI
C. The future of human beings
D. The fight between humans and AI

How could we tell time if there were no watches or clocks any where in the world?
The sun was probably the world’s first “clock”, except in the far north, where the Eskimos live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun fully, if you don’t have a clock that shows time, you still know that when the sun shines, it’s day, and when it’s dark, it’s night. The sun can not only tell you whether it’s day or night but also it’s morning, noon, or afternoon. When the sun is almost over your head, it’s noon.
People who live near the sea can tell time from the tides（潮水）. In the daytime, for about six hours, the water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every twenty-four hours.
Seaman on a ship tells time by looking at the moon and the stars. The whole sky is their clock.
In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.
A sand clock is an even better clock. If you had fine dry sand in a glass shaped like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom part in exactly one hour. When the hourglass is turned over the sand will take another hour to go back again.
1. From the passage we can know there are ____ ways to tell time besides the clock and watch.
A. three B. four C. five D. seven
2. The Eskimos in the far north can’t use the sun for a clock because ___________.
A. they know very little about the sun
B. the sun there never goes down in winter
C. It’s too cold for them to go out to watch the sun
D. it has long dark winters and long light summers
3.This passage is probably a kind of ___________.
A. news B. science
C. advertisement D. sports
4.What’s the best title for the passage?
A. Different ways to tell time.
B. How the clock was invented.
C. The development of the clock.
D. A useful machine to tell time.

阅读与回答问题。
Camping in your backyard is full of fun, whatever your age. It's great for keeping us relaxed. It offers chances to check the night sky and to be noisier than usual. It lets us have friends over to stay who might not fit inside the house! Follow these instructions and you'll have a night you’ll never forget!
Put up your tent.
Depending on the number of family members and guests, you may need more than one tent. Tell your friends to bring their tents if needed. Follow the instructions or check out the articles on how to put up a tent on the Internet.
Prepare your bedding.
You'll want your guests to be able to relax in comfort. Put something soft to lie on on the floor: A blow-up air mattress or thick comforters may work well. Fill the tent with soft toys and blankets (毯子). Have lightweight sleeping bags or cotton blankets. They are especially important because the night temperatures may drop greatly.
Prepare a seating area.
If you have a picnic table, that would work best. If not, set up a few chairs and a small table to set out drinks and food. A simple choice is to lay out a blanket in the sun, so that your friends can eat and talk. Be sure the grass isn’t wet!
Make memories.
Plan some activities. You're camping in the backyard, so it's time to make the most of being outdoors.
Have a camera nearby to take silly photos of you, your family members, and your friends. Take one large group shot with everyone smiling and laughing. Be sure to make copies for everyone!
