【题目】Do Cyber Schools Make the Grade?

Students in Caldwell, Idaho, can attend class in their pajamas!

At Vallivue Virtual Academy, courses are taught online. Students work at home with parents, who serve as learning coaches. A certified teacher oversees the students' progress.

The cyber school was launched as a free option for students in kindergarten through grade 8 who have trouble succeeding in the district's traditional public school. Supporters of the program say that virtual learning can help students work at their own pace. If students struggle with subjects, they can take those courses online and spend more time on them. Valerie VanSelous, a teacher from Hopewell Township, N.J，agrees. "Teachers, students, and parents need to accept new technology and not be afraid of it. Offering different teaching aids just might be the key to unlocking a student' s potential. "

Some also believe that attending virtual school can prepare students for college and for work after graduation. "We need to be responsible for working on our own,” says Angela Goscilo, a senior from Pound Ridge, N.Y. "We need to develop technology skills that will help us in whatever we do. Getting an early start is a good idea."

Not everyone gives cyber schools a passing grade， however. Some educators argue that online learning makes it hard for students to make friends. Payton Mcdonough, 13, a seventh grader from Glencoe, m., agrees. " I don't know how I could sit at a computer all day without actually interacting with my peers and teachers," he says.

In addition, virtual schools don’t have enough structure. Students who take online courses can set their own schedules, which will cause problems for students who have trouble staying motivated.

Many parents also feel that cyber schools put unrealistic time demands on them because they have to oversee their kids' daily work. Many of them have full-time jobs. How are they going to run their children's education, excel in their jobs, and take care of their other responsibilities at home?

【1】What is the cyber school intended for?

A.Reducing the time students spend online.

B.Helping those who struggle in traditional schools.

C.Allowing teachers to work at their own pace.

D.Encouraging students to learn about technology.

【2】What does the underlined sentence mean in paragraph 5?

A.Not everyone approves of cyber schools.

B.Not everyone has attended a cyber school.

C.Not everyone has given cyber schools a test.

D.Not everyone cares about students in cyber schools.

【3】How do working parents feel about overseeing their kids' daily work?

A.It's worthwhile.

B.It's unnecessary.

C.It's demanding.

D.It's discouraging.

【4】What is the main idea of the text?

A.Students in Caldwell can attend class at home every day.

B.There are various arguments for and against virtual schools.

C.It's important for students to learn to work in the virtual world.

D.Cyber schools are better than traditional schools in many ways.

【题目】Climbing Without Ropes

The popular image of the mountain climber is of a person carefully climbing a steep cliff with a network of safety ropes, but it is not the only kind. Many climbers now enjoy bouldering. It’s more accessible and better for the environment.

What is bouldering?

Bouldering is a sport that involves climbing on, over, and around boulders up to approximately twenty feet above the ground. Participants employ no safety ropes.

Why boulder?

places to climb, such as climbing walls at gyms and parks, easy to find

less time commitment to bouldering than to mountain climbing

intellectual and physical enjoyment as one solves problems

Bouldering Terms

crimp: a very small handhold

foothold: a place where one may place a foot to aid in climbing boulder

jug: a very large handhold that is easy to use

Here is an example of a climber addressing a bouldering problem.

Figure 1: The climber has two routes she could take, one to the left and one to the right. The left one appears easier because it has a jug within easy reach, but look what happens if she chooses that direction. She gets stuck on the rock and has to go back down. Sometimes that is even difficult than going up.

Figure 2: The climber takes the one to the right this time. using a foothold and placing her right hand in a crimp, she is able to life herself up and locate other handholds. After only a few moves, she is able to throw her leg over the top of the boulder and pull herself up.

The Rise of the Smart City

The information revolution is changing the way cities are run - and the lives of its residents. Cities have a way to go before they can be considered geniuses. But they’re getting smart pretty fast.

In just the past few years, mayors and other officials in cities across the country have begun to draw on 【1】 - about income, traffic, fires, illnesses, parking tickets and more - to handle many of the problems of urban life. Whether it’s making it easier for residents to find parking places, or giving smoke alarms to the households that are most likely to suffer fatal fires, big - data technologies are beginning to 【2】 the way cities work.

Cities have just 【3】 the surface in using data to improve operations, but big changes are already under way in leading smart cities, says Stephen Goldsmith, a professor of government and director of the Innovations in Government Program at the Harvard Kennedy School. “In terms of city governance, we are at one of the most 【4】 periods in the last century,” he says.

Although cities have been using data in various forms for decades, the modern practice of civic analytics（民情分析）has only begun to take off in the past few years, thanks to a host of 【5】 changes. Among them: the growth of cloud computing, which dramatically lowers the costs of storing information; new developments in machine learning, which put 【6】 analytical tools in the hand of city officials; the Internet and the rise of inexpensive sensors that can track vast amount of information such as traffic or air pollution; and the widespread use of smart phone apps and mobile devices that enable citizens and city workers alike to monitor problems and 【7】 information about them back to city hall.

All this data collection raises understandable privacy 【8】. Most cities have policies designed to safeguard citizen privacy and prevent the release of information that might 【9】 any one individual. In theory, anyway. Widespread use of sensors and video can also present privacy risks unless 【10】 are taken. The technology “is forcing cities to face questions of privacy that they haven’t had to face before,” says Ben Green, a fellow at Harvard’s Berkman Klein Center for Internet and Society and lead author of a recent report on open-data privacy.
