The Horn of Plenty is one of the largest natural health food stores within the Greater Hamilton area. We are big supporters of buying locally and we are here to tell you why it is so important for your family, the community and the environment.
The concept of buying locally is simple: buy food produced, grown, or raised as close to your home as possible. Not only will your food be fresher and tastier, but you are helping protect the environment and are supporting businesses within your community and reducing pollution.
Better for the Environment
Sustainability(持续性) and global warming are such hot topics at the moment, and many people want to do their bit to help support a healthier environment. Small action carried out by many people can make a big difference. Most materials in an average North American meal have traveled about 1,500 miles to get from farm to plate. To cut out a big part of this travel would greatly reduce not only pollution from transportation and refrigeration but also customers’ expenses as well.
Taste and Nutritional Content
Locally-grown fruits and vegetables are usually sold within 24 hours of being harvested. Because they are picked at the height of ripeness and travel only a short distance to the market, their freshness, nutrition, and flavor are kept. Produce trucked in from far away may lose both taste and nutritional content.
Community and Home Values
When you buy direct from a farmer or buy locally-grown foods, you are engaged in a time-honored tradition between a grower and an eater. You also help keep dollars within your community.
1.According to the author, when you buy locally-grown foods ________.
A. you are making money from your community
B. you will contribute to protecting the environment
C. you will become much healthier and prettier
D. you can see how fruits and vegetables grow
2.It can be inferred from the third paragraph that ________.
A. the cost of transporting food is passed on to the customers
B. global warming is the most serious problem now
C. North American food is rich in various kinds of materials
D. most people support buying legally
3.Locally-grown fruits and vegetables taste good mostly because ________.
A. they are sent to the market at a high speed
B. they aren’t polluted by chemical fertilizers
C. they can be harvested at any time
D. they are picked when they are fully grown
4.What does the passage mainly talk about?
A. The popularity of the Horn of Plenty.
B. The way to keep your food tasty and healthy.
C. The benefits of buying locally.
D. The importance of protecting the environment.
Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into a
physical object. This is now possible with the help of 3D printers. Such machines were once used just
by universities and big companies, but now, stores with 3D printing services are appearing around the
United States.
Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The store
is filled with tools like a laser cutter, an industrial sewing machine and 3D printers. The Jaycoxs offer
3D printing classes and services for anyone who is interested.
"I think 3D printing is going to be huge. It's going to have a huge effect on society as a whole."
One of the students in a recent class was KiChong Tran. He plans to open a 3D printing business in
Cambodia.
3D printing services are becoming available for American consumers.
The UPS Store is a nationwide retailer (零售商 ) that provides shipping, copying and other
services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke
Jones owns one of the stores in San Diego.
"The demand has been amazing. It's been much more than I would have imagined." The UPS
Store plans to add 3D printers in three more stores.
At The UPS Store, the cost of the object depends on the amount of materials used. The store
charges up to $95 an hour to design the object with computer software that creates a digital file to
guide the printer.
Mr. Jaycox predicts that within five years, 3D printing technology could become more popular.
But KiChong Tran says even current technology can make a difference in a developing country like
Cambodia.
"With 3D printing, you can give them tools; you put it in their hands so they are responsible
more for their own development and they learn skills beyond just learning English and becoming a
tour guide or something like that or working at a bank; you can actually create things that give value
to the world."
He says it's not just in Cambodia but anywhere where there is a 3D printer that it can turn a good
idea into reality.

A. attract consumers to buy 3D printers B. explain the importance of 3D printing
C. introduce a new technique-3D printing D. describe the rapid development of technology
2.The Build Shop LLC is a store .
A. promoting 3D printers B. offering 3D printing classes and services

3.At the UPS Store, the price of a 3D object depends on

C. the size of the object D. the labor service it needs
4.The attitude of KiChong Tran towards the development of 3D printing technology is
A. positive B. objective C. uncertain D. critical
As a little child,1 was always plump（胖的）.In college I started blowing up. It got out of control
when l went to law school.
I'd made a decision a thousand times: I'm going to lose weight now. But what motivated（激发）
me to get serious about it was turning 30.1 weighed 414 pounds.1 was always tired. Some of my
family members have suffered from heart disease, and l was frightened. I also wanted to look better.
So after my birthday,1 walked into the office of a weight loss doctor.
She was very understanding. Her focus was on balanced meals and she wanted me to exercise.
Walking was all I could do at first. I started by walking a few blocks and gradually increased the
distance, until one weekend, I heard myself saying, "Wow, this seems pretty easy." So I started to run.
1 was losing nine or ten pounds a month, and I had more energy. I started to think about the New
York City Marathon. For years,1 watched the runners and thought, "This looks like fun, but I could
never do that." But now I realized that maybe I could.I joined the New York Road Runners.I ran a
l0km, then a half marathon.I still wasn't confident I could run a full 26 miles. But I told myself I was
going to do it, no matter what.
By my 33rd birthday,1 was down to 180 pounds. I started formally training for the marathon.
And on the morning of November l, I stood on the Verrazano Bridge in Staten Island with more than
40,000 0ther runners, waiting for the event to start.
It was unbelievable to have the audience cheering me on, handing me cups of water. And I
crossed the finish line. My friends sprayed（向……喷射）me with beer, as if I'd won the Super Bowl.
And at that moment,I knew: If I set my mind to something, nothing is impossible.
