Teachers say the digital age has had a good and a not-so-good influence on the American teenagers. More than 2,000 high school teachers took an online survey.
75 percent of the teachers said the Internet and digital search tools have had a “mostly good” use for their students' research habits and skills, But 87 percent agreed that these technologies "make the students not have enough attention.” And 64 percent said the technologies “do little to help them in courses.”
Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital research tools are helping students learn more, and learn faster. Teachers really like these tools, because they are ways to make some of learning exciting. Young people enjoy using these tools. And the goal is to help them become creative students of meaningful work, and not just that kind of copyist.
But one problem the survey found is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust(信任) too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the online information is good or bad.
Another problem the survey found is something that might not seem like a problem, at all, being-able to quickly find information online. Teachers say the ability of their students to work hard to find answers is becoming weaker. They say students depend too much on search engines (引擎) and do not make enough use, of printed books or research, librarians.
Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities.
【小題1】      of the teachers agreed technologies may stop students from having enough attention.

A.50% B.64% C.75% D.87%
【小題2】 How many problems are mentioned (提及) in the passage'?
A.One B.Two. C.Three. D.Four.
【小題3】Teachers like the digital search tools because they can        .
A.make some of learning exciting
B.help students find answers easily
C.tell whether the information is good or not
D.help students copy the work done by others
【小題4】What does the writer want to tell us by writing this passage?
A.Digital search tools have quite a lot of advantages.
B.Students don't know how to use the digital search tools.
C.Many teachers are worried about the students' abilities.
D.Students should learn how to use the digital tools in a right way.

Hip hop or rap (說唱) music started on the street and in the clubs of the New York City in the 1970s. People rap to express how they feel about their lives and problems.
Rapping in class.
Would you like to rap in class? Well, actually hip pop music is played in more than 10,000 schools in the USA. Why? There is a new school program called “Flocabulary” in which teachers use texts and hip hop CDs to help teach different school subjects. The words of the songs are just what students are studying. This makes learning easy and fun. Students and teachers are excited about the good results it has had on exam marks. Mr. Lee, a teacher in a high school, said, “I’ve used hip hop songs in class, and I have never seen my students so crazy about history! You can’t imagine how well they remember what I teach! We even try to write our own songs.”
Whose idea was Flocabulary?
Blake Harrison, a high school student, was the first person to come up with the idea of Flocabulary. The word “Flocabulary” comes from the word “flow” and “vocabulary”. “Flow” is a rap word for “style”, or the way a rapper says the words of a song. “Vocabulary” means the words you have to learn in a language. How did he get the idea? Well, he realized he could remember the words of a hip hop song very easily. So, why not make lessons into songs? Today together with Alex Rappaport, a song writer, Blake produces hip hop songs for math, science and literature (文學(xué)). They are now used in schools with great success.
【小題1】 Rap music started ______ in the New York City in the 1970s.

A.in a high schoolB.in a music class

【小題2】From the passage, we can learn “Flocabulary” is a program to ______.

Bai Yansong, a famous TV host, expressed his support for students wearing green scarves (綠領(lǐng)巾) at a primary school in Xi’an. He wore a green tie on a TV program on October 19, 2011. “I just want the students to know that I’m also wearing green. And we are all great people and are as good as those wearing red scarves.”
The First Experimental Primary School in Xi’an made children with poor schoolwork and behavior wear green scarves. Parents whose children wore green scarves were angry. “The children still need their self-esteem (自尊心) even though they are very young, and they know the green scarf means something is not quite right,” said one mother. Now, the school has stopped the practice.
Educational expert Li Zhenxi said that primary and junior high school students have strong self-esteem. They are eager to be respected and understood. Punishment will hurt them. “It’s better to encourage them rather than separating some ‘bad’ students,” he said.
A survey made by the Ministry of Education (教育部) shows that 75 percent of students feel nervous and scared when the teacher is about to announce their grades. Some schools have done better in protecting students’ privacy and encouraging them. In American schools, teachers post test results on the wall. Instead of using student names, they use secret numbers. This way, students know their secret numbers and can check their own grades only. Some teachers might call the students up to the desk and tell them their scores one at a time.
But test scores are not the only measures of a student’s ability. Everyone has his own strengths and everyone can make great progress by working hard.
【小題1】Bai Yansong wore a green tie in a TV program in order to _______.

A.show people his special dressing style
B.call on people to live a green life
C.tell students green-scarf students are also good students
D.remind students wearing green scarves means being bad
【小題2】Why did those parents whose children wore green scarves feel angry?
A.Because their children did do well at school.
B.Because they thought the school didn’t have the right.
C.Because it was against the law.
D.Because it hurts their children’s self-esteem.
【小題3】According to the article, which of the following is TRUE?
A.Primary school students are too young to know what self-esteem is.
B.Separating some “bad” students helps create good learning environment.
C.Most “good” students like their teachers to announce their scores.
D.Using secret numbers instead of students’ names can protect their privacy better.
【小題4】Which of the following may the writer agree with?
A.The green scarves system can make students work hard.
B.Student’s ability should not be measured only by test scores.
C.Students who get low marks should use secret numbers.
D.Teachers should tell students their scores secretly one by one.
【小題5】What does the word “measure” mean in the last paragraph?
A.長度B.尺度
C.方法D.標(biāo)準(zhǔn)

It was a cold day, but the students from Prosser Middle School in Chicago were sorting through the waste when they found that their school produces 1,500 pounds every day.
Prosser is just one school that throws out nearly 4,000 meal trays every day. Counting all of Chicago’s public schools, the number comes to nearly a quarter of a million a day. That’s more than 1 million a week and about 5 million a month. 
“None of the trays are being recycled,” said a teacher. “ Everyone agrees that it’s very bad.”
Luckily, concerns about the environment and health have made some US cities take action. Dozens of schools have begun programs to reduce the use of food trays in school.
These schools have also banned (禁止)some fast food, including McDonald’s. Instead, they offer students recyclable trays. They encourage students to sort out lunchroom waste, then wash and recycle milk cartons and trays . So far, the program has helped schools to save a total of 820,000 trays each week.
Jay Stream Middle School in Illinois teaches its students how to collect trays. The school has cut its lunchroom waste by two thirds now that students recycle their used trays instead of breaking them.
Prosser Middle School also sees the benefits of the program. Students have organized about 20 clubs and volunteer activities to cut down on cafeteria garbage. They now recycle 80 percent of the school waste. “ I joined the club,” said Erika Santana, a 16-year-old junior in Prosser, “because I want to make Earth a better place.”

On February 9th, 2013, Sarah Darling was walking along the street when she met a homeless man named Billy Ray Harris. She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act would change their lives.

Sarah didn’t realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the following morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, he also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.
Bob Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet.
That is not enough. Billy is living with a person who is generous instead of living in the streets. And that’s not all—Thanks to the news report, he got together again with his older brother, Edwin Harris who he had been unable to find for 27 years.
