3 . A common claim states that a sheet of paper cannot be folded in half more than seven times. But is this true?

In 2002, Britney Gallivan, then a junior in high school in Pomona, California, folded a single piece of paper in half 12 times. She currently holds the Guinness World Record for the most times to fold a sheet of paper in half.

The prompt that led Gallivan to accomplish this was an extra-credit challenge in math class to fold anything in half 12 times. Her teacher asked the students to fold something thicker: a piece of paper.

Gallivan said “it was very frustrating, as I had many unsuccessful attempts at trying to fold different papers in half. I began to question if folding paper in half more than eight times could be impossible.” However, Gallivan recalled. “I knew I needed to understand what was limiting the folding progression.”

The equations (方程式) that Gallivan came up with calculated how many times a sheet of paper could be folded. She found that in order to fold many times, a long thin sheet is needed — the more a sheet is folded, the thicker the resulting stack becomes, and once the stack becomes thicker than it is long, there is nothing left to fold. She ultimately set her record with a sheet of tissue paper she found online that was 4,000 feet (1,219 meters) — more than three-quarters of a mile, or over a kilometer long, Guinness World Records noted.

“Working on the problem took a tremendous amount of time and effort,” Gallivan said. “As frustrating as it was at times, I learned an immense amount from the experience, which has been valuable to me throughout my life in more capacities than one would expect.”

Since Gallivan set her record, others have made claims of folding a sheet of paper more than 12 times. Still, “I anticipate that my current record will be surpassed,” Gallivan said.

1. What prompts Gallivan to accept the challenge?

A．Peer pressure.

B．Mathematics anxiety.

C．Academic requirement.

D．Guinness World Records.

2. Under what circumstances is it impossible to fold a paper in half more times?

A．The stack is as thick as it’s long.

B．The paper is neither long nor thin.

C．The stack is thicker than it’s long.

D．The paper is longer than it’s thick.

3. What can we learn about Gallivan’s attempts?

A．It’s risky.

B．It’s fruitless.

C．It’s meaningless.

D．It’s energy-consuming.

4. What can we infer from the passage?

A．Gallivan’s record is impossible to break.

B．Folding paper in half is merely a math problem.

C．Folding things in half may not be limited to 12.

D．Folding paper 12 times is a required credit in high schools.

5 . Social media networks have been shown to have greatly changed students’ social behaviour. But the relationship between social media and students’ English language writing has been largely ignored (忽视). So our team of four researchers studied one English as a Second Language (ESL) class at Fiaseman SenirHigh School in Tarkwa, southwestern Ghana. Our research focused on a Form 2 class, made up of 47 students aged 17 and 18 on average. It was one of the largest classes in the school, which offered English as a general subject.

The study found that the students spent really long periods of time on various social media platforms (平台) . But most of the sites they visited were not about learning. That was worrying. One student said, “I visit social media every day. I can’t count. I’m always there. It is very difficult to control my presence there. I truly don’t know what to do.”

We also found that their social media use had resulted in their use of shortened forms of English words-such as “4” in place of “for”, “u” in place of “you” and “d” in place of “the” --in their writing, including in their English examinations. These are the unacceptable written forms of English.

We concluded that the way in which English is being used in examinations by students is being undermined by their use of the English language on social media. This is a growing trend (趋势) that will see students struggle to get ahead in the subject, as more formal English language writing is needed for examinations and further studies.

We recommend that those involved in education should consider connecting teaching practices that take advantage of social media to attract students. This would allow students to learn during their time on social media platforms. Also, teachers should help students choose proper social media sites. They should tell students about the importance and dangers of social media and how to use them, especially for educational purposes.

1. What does the student want to convey through his words?

A．He used social media for educational purposes.

B．He was worried about his privacy on social media.

C．He lacked the knowledge of properly using social media.

D．He was interested in new information on social media.

2. What has students’ social media use led to according to the study?

A．Creativity in English expressions.

B．More chances to master new words.

C．Increased competition among them.

D．Disappointing English writing performance.

3. What does the underlined word “undermined” in Paragraph 4 probably mean?

A．improved slowly.	B．proven scientifically.
C．influenced negatively.	D．corrected effectively.

4. What does the author suggest doing?

A．Guiding students in using social media as a learning tool.

B．Encouraging students to join in outdoor activities regularly.

C．Limiting the time of students’ using their phones strictly.

D．Providing different online courses for students.

6 . Here are five common mistakes distance learners make.

Choosing the wrong school.     1     “Diploma mill” schools charge unsuspecting students thousands of dollars for worthless degrees, whereas trustworthy schools are able to give their students diploma they are proud of. Before you enroll in an online school, do some research to find out what type of program, resource and support will be provided.

Putting off things. Many students never finish their degrees because they lack the self-discipline and motivation to sit down and get their work done on a daily basis.     2     Many students have found it beneficial to create a deadline for receiving their degrees and set small monthly, weekly, and daily goals that will allow them to reach that deadline.

Failing to connect with their peers and professors.     3     Building meaningful relationships with your peers and professors can allow you to learn more, stay motivated, and have a way to express your own understanding of the subject matter. So stay connected through message boards, chat rooms, email, and other virtual resources.

Scaring potential employers. More and more people are recognizing the validity (有效性) of online education.     4     Some potential employers may see warning signs if you announce that you have earned your degree through the Internet. Even if you attend a famous school, avoid calling attention to the fact that your studies are done online.

    5     There’s a lot of online material available to help out students. Make sure you know where you can get the help you need. Be aware of the general resources such as virtual dictionaries, online books, and resources that relate to your specialized subject matter.

A．Paying too much.

B．Paying no attention to online resources.

C．However, be aware that it is not completely accepted by all people.

D．Many students attend an online course feeling as if it is very easy.

E．Selecting the right school is the biggest difficulty that distance learners face.

F．If you often put off your work, set some specific goals for yourself and stick to them.

G．One of the most rewarding experiences in education is learning through teamwork.
