Basketball is a much loved and active sport that is enjoyed by many for fun and exercise. It is over 100 years old and is played by millions of people all over the world. It is believed that the first basketball game in history was played on 21 December,1891.Then in 1936 in Berlin,it became an event at the Olympics.
Basketball was invented by a Canadian doctor named James Naismith,who was born in 1861.When he was a college teacher,he was asked to think of a game that could be played in the winter. Dr Naismith created a game to be played inside on a hard floor. Dr Naismith divided the men in his class into two teams and taught them to play his new game. Players on the same team must work together to get the ball in the other team’s basket. At the same time,they need to stop the competing team from getting the ball into their own basket.

（2023·河北改编）
Last week we went on a school trip to a science museum. Ms Liu,the guide,showed us around a smart home.
We started with the front door. Ms Liu asked me to ring the doorbell. I didn’t notice the tiny camera that was fixed just above it. After I pressed the doorbell,the camera sent a live video to the home owners."They can electronically open the door when they are not at home," said Ms Liu.
The other thing I couldn’t see on the door was a lock."There must be one," I thought. At this time,Ms Liu took out a smartphone and put it against the door. And it opened."Oh,the key is on the smartphone."
After entering the living room,I saw a computer on a table. By using the computer,the owners can control how much energy is used. In this way,they can manage their living cost.
One of the rooms I wanted to see most was the bedroom. To my great surprise,the bed disappeared into the floor at the touch of the smartphone. The window has a smart blind（百叶窗）.It can be raised and lowered with a voice.
As I left the smart home,I looked back on what I had just seen. Scientists often say that these products are improving our life.I think the technology in the smart home may make us lazier.However,there is no doubt that it will become more popular in the homes of tomorrow.
15. Where is the key to the door？（不超过10个词）
