【題目】Who could have imagined that a treadmill（跑步機(jī)）on wheels would one day become a thing?!? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question “How can I use a treadmill outdoors?” He finally came up with a new design, adding an electric motor, and the Lopifit was born. It’s similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery（電池）and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast（慣性滑行）, all you have to do is stay still and admire the view. To stop, you have two hand breaks.

The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you’re going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you “walk” really fast without much effort, or walking at cycling speed, if you will.

【1】Lopifit is an electric bicycle which ________.

A. can be powered by the drive chain

B. can work without an electric motor

C. works when you walk on the treadmill

D. stops when you slide the treadmill forward

【2】What is Paragraph 3 mainly about?

A. The design of a Lopifit. B. The function of a Lopifit.

C. The structure of a Lopifit. D. The operation of a Lopifit.

【3】What is probably the author’s attitude towards Lopifit?

A. Confident. B. Concerned.

C. Curious. D. Doubtful.

【答案】

【1】C

【2】D

【3】A

【解析】這篇文章主要講了電動(dòng)自行車Lopifit是一款與眾不同的交通工具，你可以通過(guò)在跑步機(jī)行走來(lái)為它充電。作者對(duì)這款電動(dòng)自行車的構(gòu)造和如何操作進(jìn)行了詳細(xì)的說(shuō)明，并且作者認(rèn)為這款電動(dòng)車的前景非常好。

【1】根據(jù)Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill. 可知電動(dòng)自行車Lopifit是一款與眾不同的交通工具，你可以通過(guò)在跑步機(jī)行走來(lái)為它充電。所以選C。

【2】根據(jù)To use the Lopifit, simply turn on the battery（電池）and use your foot to slide the treadmill backwards and start the motor. 可知，第三自然段主要講了電動(dòng)自行車Lopifit如何操作。

【3】根據(jù)But the Lopifit does have the special advantage of helping you “walk” really fast without much effort, or walking at cycling speed, if you will. 可知作者對(duì)于電動(dòng)自行車Lopifit的態(tài)度是非常有信心。

【題目】With busy lives, it can be hard to find time to volunteer. However, the benefits of volunteering are great to you, your family, and your community(社區(qū)).

One of the better-known benefits of volunteering is the effect on the community. Volunteering allows you to connect with your community and make it a better place. Volunteering also strengthens your ties to the community and broadens your support network, exposing(使暴露) you to people with common interests, neighborhood resources, and fun and satisfactory activities.

While some people are naturally outgoing, others are shy and have a hard time meeting new people. Volunteering gives you the opportunity to practice and develop your social skills, since you are meeting regularly with a group of people with common interests. Once you have the desire, it’s easier to make more friends and contacts.

Volunteering provides many benefits for both mental and physical health. You’re doing good to others and the community, which makes you experience the pleasure of success. Your role as a volunteer can also give you a sense of pride and identity.

Reducing the risk of depression(沮喪) is another important benefit of volunteering. A key risk factor for depression is social isolation. Volunteering keeps you in regular contact with others and helps you develop a solid support system, which in turn protects you against stress and depression when you’re going through challenging times. Volunteering is good for your health whether you are young or old, but it’s especially good in older adults.

Volunteering offers you the chance to try out a new career without making a long-term commitment. It is also a great way to gain experience in a new field. Volunteering work can expose you to professional organizations or internship（實(shí)習(xí)）that could be of benefit to your career. That volunteer work is unpaid doesn’t mean the skills you learn are basic. Many volunteering opportunities provide training. In addition, volunteering can also help you build upon skills you already have and use them to benefit the greater community.

Volunteering is a fun and easy way to explore your interests and passions. Volunteer opportunities that match both your goals and your interest are most likely to be fun and satisfying for you. Doing volunteer work you find meaningful and interesting can be a relaxing escape from your day-to-day routines of work, school, and family commitments. Volunteering also provides you with renewed creativity, motivation, and vision that can be carried over into your personal and professional life.

【題目】Before your child's final exam: and the graduation announcements, you face a significant task together: choosing the right college or university. There is no "one size fits all" approach to selecting a college—it's a very personal process for most teenagers. Consider a wide range of factors to help your child make the best possible choice.

Discuss with your child her post-high school choices, such as college, finding work or starting a business, or joining the army. If you determine together that college is the best choice for your child, talk about the importance of college, and her longer-term goals by going to college.

Talk to your child about what she thinks is important in a college experience and share your opinions as well. Identify the issues that will directly impact her college choice, such as her grades, test scores and family finances. Then make a list of the key criteria for her dream school, including factors such as the school's location, its size, the types of prograM:, the after school activities available and the type of financial aid available.

Prioritize the item: on your child's list, at least to the extent of sorting it into "must-haves," "highly desirable" and "nice-to-have" categories. Put these factors into an online search engine specifically designed to identify colleges and universities that best meet your criteria, such as that offered by CollegeBoard.org. Start with the most important criteria, then experiment with additional factors to narrow the search results to a number you can work with, such as 10 or 20 different schools.

Use the search results as a guide to further focus your college search. Research each school by reviewing its website, requesting information directly from the school and attending local presentations about the school.

【1】The underlined word "prioritize" in Paragraph 4 probably means "______".

A. list in order of importance B. write down

C. add to D. do research into

【2】What can we learn from the passage?

A. It's better to decide the college for your child.

B. It's necessary to take your child's opinion into consideration.

C. There is a "one size fits all" way to select a college.

D. An online search engine is of great help to you.

【3】What's the author's purpose of writing the passage?

A. To argue B. To persuade

C. To introduce D. To amuse

【4】Which of the following shows the structure of the passage?

Khan Academy is a website providing a free education for any person. The website includes more than 4,000 short teaching videos about many different subjects. Every month, over 7 million people go to the Khan Academy website to watch its videos.

Khan Academy began with one man named Salman Khan. As a young man, Khan got a degree from Harvard Business School and began to work in business.

In 2006, Khan used the Internet to help his young cousins, who lived far away, with their mathematics schoolwork. He drew numbers and pictures on the website to teach them. After a time, he put his videos onto the website YouTube, where his cousins could watch them any time they wanted. But Khan noticed that other people were also watching his videos on YouTube.

By 2009, the number of people watching his videos on YouTube was getting very large. Khan decided to make the videos his job instead. So he officially began Khan Academy, providing videos on mathematics and other school subjects.

Some people did give Khan small amounts of money, but he was still having a hard time. Later, a woman told Khan that Bill Gates uses Khan Academy for his kids. After that, the Bill and Melinda Gates Foundation began giving money to Khan Academy. In 2010 Google gave the website money too, wanting Khan to translate his videos into the world’s most common languages. Today, people can see Khan’s videos in many different languages.

Some people think that Khan Academy will be the way more and more people learn in the future. Teachers can use it in their classrooms. Khan believes that Khan Academy will never, and should never, replace a school. But he believes teachers and students can use it to make schools better.
