Nowadays, many teens are badly addicted to using phones. It probably won't surprise you that teens are texting more than ever before. Instead of sleeping, Kenny Alarcon, 16, often texts with his friends through the night. Frances Garcia, a high school senior, sends and receives about 1000 texts each day. Both Frances and Kenny wake up several times during the night to text. Kenny even sleeps with his phone under his pillow.
Dr.Elizabeth Dowdell, a professor at Villanova University in Pennsylvania, says that it's common for teens to be interrupted by texts while sleeping. If they often lose sleep, Dr.Dowdell says, “teens may become angry, or depressed. A lack of sleep can lead to weight gain and even obesity because many people turn to junk food for quick energy when they are tired.”
Some experts are worried about how texting is affecting teenagers' lives. One concern is that students might not learn correct grammar and spelling if most of the writing they do is made up of text messages. Some people also worry that teens don't spend enough time talking with others face - to - face, which could be hurting their relationships with friends and family. Moreover, all that texting takes away hours that could be spent studying, exercising, taking up a hobby, or just relaxing.
According to Dr. Dowdell, teens need to learn that they can and should turn off their phones sometimes. She had Kenny and Frances do an experiment. These were the rules: No phone for 48 hours. No computer or Internet either, unless it was for schoolwork.
After 48 phone - free hours, Kenny and Frances were interviewed. “Wow, it was pure torture （折磨）!” Kenny joked. Kenny missed his friends, and he was sad at times. But he also felt relief from the constant texting. He spent time reading books and talking with his family, which he really enjoyed. Frances had an even happier result. “I loved it!” she said, “I was going to the gym and hanging out with friends and playing basketball. I had a wonderful experience.” Frances decided to continue the experiment for a while. “I think I'll be so much smarter and healthier,” she explained, “everybody in the world should try it.”

原文
I soon saw two pirates (海盗) lying at the back of the ship. One was dead. The other, Israel Hands, was hurt and calling for rum (朗姆酒). I gave Hands the rum. As he drank it, the color returned to his cheeks.
“I am taking over this ship, Mr Hands,” I said. “You will treat me as your Captain Jim.”
He looked at me surly, but he could do nothing. I then took down the Jolly Roger flag and threw it into the sea.
“You want to get ashore (海岸), now you need my help.” said Hands, “Tie up my wound, then I’ll tell you how to sail the ship.”
“I want to get to North Inlet.”
Hands agreed to help me, and the Hispaniola was sailing along the coast of Treasure Island. I tied up the knife wound in his leg with a cloth. After eating and drinking, he looked better.
We soon arrived at the North Inlet. Hands was very good at guiding me in, we turned into the beach, and came easily to have a rest.
I was busy bringing the ship in and forgot to watch Hands. When I turned around, Hands was standing behind me, his knife ready. I quickly climbed up the ropes and prepared both my guns.
“One more move, I’ll kill you! Mr Hands.” I shouted.
Suddenly, a knife flew through the air to me, both guns in my hands fired, and fell into the sea together with Israel Hands.
Then I climbed off the ship and swam ashore. I arrived at the fort (城堡) and walked in when my foot touched someone’s leg. Someone was sleeping on the ground. He moved but did not wake. Then suddenly a shrill (尖厉的) voice called out in the darkness:
“Pieces of eight! Pieces of eight!”
It was Long John Silver’s parrot, Captain Flint!
“Who is it?” Silver cried.
I turned to escape, but someone closed his arms around me and held me tight.
------- From Treasure Island
题目
Why did Jim help Hands tie up the wound in his leg?
A. Because Jim took a pity on Hands.
B. Because Jim got on well with Hands.
C. Because Hands would be his new captain.
D. Because Hands could guide Jim to sail the ship.
What does the underlined word “surly” mean in the story?
A. Angrily.
B. Sadly.
C. Politely.
D. Patiently.
Which is the correct time order according to the story?
a. I climbed off the ship and swam ashore.

c. A knife hurt me and Hands fell into the sea.
d. After drinking and eating, Hands feels better.
e. We turned into the beach, and came to have a rest.
A. e - b - c - d - a
B. d - e - b - c - a
C. c - e - b - d - a
D. d - b - e - c - a
What can we infer from the story?
A. Jim was caught by Silver at the fort.
B. Jim was one of the pirates in this story.
C. There were only two pirates in the ship.
D. Hands arrived at the fort with Jim at last.
答案及解析
答案：D
解析：根据文中 “You want to get ashore (海岸), now you need my help.” said Hands, “Tie up my wound, then I’ll tell you how to sail the ship.” 可知，Jim帮Hands包扎伤口是因为Hands能指导他驾驶船，所以选D。
答案：A
解析：前文提到Jim要接管船并让Hands把他当船长，Hands肯定不高兴，surly所在句子“He looked at me surly, but he could do nothing.” 结合语境，他生气地看着Jim但又无能为力，所以surly意思是“生气地”，选A。
答案：B
解析：首先是给Hands吃喝后他感觉好多了（d），接着到达North Inlet，进入海滩休息（e），然后Hands准备用刀袭击Jim，Jim迅速爬上绳子拿枪（b），之后刀飞向Jim，Hands掉进海里（c），最后Jim爬下船游上岸（a） ，所以正确顺序是d - e - b - c - a，选B。
答案：A
解析：根据最后一段 “I turned to escape, but someone closed his arms around me and held me tight.” 可以推断出Jim在城堡被Silver抓住了，A正确；从文章可知Jim不是海盗，B错误；文中只提到两个海盗，但不能说明船上只有两个海盗，C错误；Hands掉进海里了，没有和Jim一起到达城堡，D错误，所以选A。

The Yellow River is known as the mother river of the Chinese people. However, flood control and disaster forecasts (灾害预报) of the river have always been challenging for people. Now, scientists can better work on these problems by giving the river a digital twin.
The digital twin of the Yellow River uses different kinds of technologies, including big data, artificial intelligence and the internet of things. Devices(设备)are set up along the river to collect real - time data about water levels, flow rates, and water quality. Then, this data is used to create a virtual model of the river, which can help scientists predict floods and other disasters more accurately.
For example, if there is heavy rain in the upper reaches of the Yellow River, the digital twin can quickly analyze the data and predict how the water level will rise downstream. This gives people more time to prepare for floods and take necessary measures to protect lives and property.
In addition to flood control, the digital twin can also help with water resource management. By analyzing the data on water quality and flow rates, scientists can make better decisions on how to allocate water resources and ensure the sustainable use of water.
The development of the digital twin of the Yellow River is a significant step forward in China's efforts to protect and manage this important natural resource. It shows how technology can be used to solve complex problems and make our lives safer and more sustainable.

I asked my dad if I had ever made him cry before because I couldn't remember ever seeing him cry.

My father was doing it because he was curious（好奇的）. It was interesting for him to see which one I would pick. He said that I just sat there and stared at the three things. He sat across from me and waited to see the result.
