One of the best aspects of travel is in discovery. Whether you're burying yourself in a new culture or wandering the streets of a foreign city, you're finding new things to see and experience. Part of that discovery is in what you learn about yourself. 1..
Here are some of those ways:
◆ 2.
Travel means new foods, cultures and places to explore. Try speaking that new language or eat a new kind of food you never knew existed. When you’re thrown outside of your normal circumstances, you’ll discover more about who you are and what you're like.
◆ The chance to reinvent yourself
At home, people can see you a certain way and classify you into a personality type that can be hard to escape. 3.. You're free to break away from how people normally see you and reinvent yourself.
◆ Building confidence
You've just traveled across a country, tried a new language and bargained over prices in a market. They're all things you didn't know you could do before, but you dug up a new-found sense of adventure and somehow made it work. 4.. And the more challenges you take on, the more sure of yourself you become.
◆ Choices and organizing skills
What's the best route to take so I see all the major attractions? What's the best way to get to the next city and back so I don't miss my flight? How should I organize my itinerary (行程)? 5.. You have to organize your trip so that you have a place to stay and transportation to and from certain destinations.
A.With travel, come challenges
B.Travel is about making choices
C.Forcing you out of your comfort zone
D.Trips don't always go according to plan
E.Having time to reflect on your life
F.Travel can give you a chance to explore other sides of your personality
G.Like most experiences, travel can change you in ways you might never have expected
Before war and time destroy more of our important cultural sites, we need to save them in 3-D digital libraries. Across 163 different countries, 1,000 natural and cultural historic places make up our most precious human heritage, which UNESCO calls World Heritage Sites.
We lose a little of that heritage every day. War, climate change and pollution have a bad effect, as do wind and rain. The $4 million a year that UNESCO spends on preservation is not nearly enough to take care of even the four dozen sites considered at approaching risk of being lost forever. Now there’s a better choice. New digital-conservation technologies let us hold on to them, at least virtually(虚拟的), through 3-D scanning, modeling and digital storage. Such projects can be accomplished through cooperation between governments, universities, industry and non-profit organizations.
To make a 3-D model, a laser(激光) scanner bounces light off an object and records the results. To reproduce every corner and opening, the scanner collects overlapping(重叠的) images from all possible angles. A computer then sews them together into one large surface image and draws lines from one point to another to create a wire-frame model. High-resolution digital cameras add color and texture. When fully put together, the models can be viewed, printed or operated.
These scans do more than preserve a memory in a database. With highly accurate measurements, archaeologists(考古学家) can find hidden passages or reveal ancient engineering tricks. School kids can explore places they might otherwise never see. And when a site is destroyed, the scans can even be used to reconstruct what was there. That has already happened for one World Heritage Site, the Kasubi Tombs in Uganda. Built of wood in 1882, they were destroyed by fire in 2010 and rebuilt in 2014, based in large part on 3-D models made in 2009. More than 100 World Heritage Sites have been already preserved as 3-D models, and conservationists are racing to record as many more as possible.

A.By listing the threats to our human heritage.
B.By introducing some damaged historical sites.
C.By quoting some experts’ views on heritage protection.
D.By explaining UNESCO’s research on World Heritage Sites.
2.What is Paragraph 3 mainly about?
A.The function of a laser scanner. B.The reflection of light off an object.
C.The process of making a 3-D model. D.The development of 3-D digital technology.
3.What do we know about the Kasubi Tombs in Uganda?
A.It is metal-framed. B.It is still in its original condition.
C.It was once destroyed in an earthquake. D.It was reconstructed thanks to 3-D models.
4.What does the author intend to say through this text?
A.Never ignore the destructive power of war.
B.Take action to reduce pollution in historic places.
C.Take advantage of 3-D technology to keep history.
D.Invest more money to preserve World Heritage Sites.
A new kind of rice, golden rice, may soon make its way into the world’s food supply by the year 2021, reports Science magazine.
Golden rice was actually first developed back in the 1990s by German scientists who were looking for creative ways to reduce rates of Vitamin A deficiency(维生素A缺乏症) in human body, which continues to be a major concern throughout the developing world. Beta-carotene(胡萝卜素), which exists in some plants, can change into vitamin A in our body.
In view of beta-carotene’s characteristics, German scientists tried and managed to make rice filled with additional beta-carotene, which has a strong red orange color. The beta-carotene that is added to this rice is actually what conduces to its special golden color.
To German scientists, developing this rice was meaningful. But as with all GM(转基因的) crops, some people warn that the golden rice may be unnecessary and even harmful, possibly having some environment consequences. Until now, those voices have prevented golden rice from being planted anywhere.
However, that’s about to change. Bangladesh now plans to become the first country to approve golden rice for planting. Recently, golden rice is receiving a series of tests before the final approval of Bangladesh. Tests conducted by the Bangladesh Rice Research Institute (BRRI) found no new farming challenges with golden rice and no big differences in quality between the crop and the traditional varieties, with the exception that golden rice is more nutritious. Some other organizations are still doing tests about the environmental influences of the crop. If those results are also good, then golden rice will have received all the approval it needs to move forward with planting.
As for the future market for the golden rice, the crop will need to gain the public’s trust. And it remains to be seen whether golden rice will offer a better nutritional and economical choice compared to other sources of vitamin A, such as other vegetables where it occurs naturally.
1.What was German scientists’ main purpose of working on rice?
A.To raise its output. B.To make it look prettier.
C.To collect its beta-carotene. D.To improve its vitamin A content in our body.
2.What does the underlined part “conduces to” in Paragraph 3 probably mean?
A.Causes. B.Changes. C.Removes. D.Lightens.
3.What do BRRI’s tests show about golden rice?
A.It can hardly grow on the farmland of Bangladesh. B.It is nutritionally better than traditional rice.
C.It may do serious harm to the environment. D.It is no different from other rice in taste.
4.How is golden rice’s future market in the author’s opinion?
A.Promising. B.Worrying. C.Uncertain. D.Hopeless.
The other day, my wife and I were in Kent County when we saw smoke on the horizon. We went about our business for a little while, and then curiosity got the better of me, and I decided to go over and check out the fire. It turned out there was a brush fire that got out of control and grew from 25 acres to 100 acres.
What struck me most about that day was the word “volunteer” written on almost every piece of emergency equipment that I could see. No one was getting paid to fight the fire that day. They were there because they chose to be, not because they had to be.
How many of us would wake up early one fine Sunday morning, get dressed in hot, bulky(笨重的) clothing and risk our lives for no money and little reward? These folks do that all the time. I live in a densely populated(人口稠密的) area, and our local fire department is volunteer. Most of the time when we see these individuals, they are either on the way to or back from an emergency. We also occasionally see them collecting money on the side of the road. With either boots or helmets in hand, they ask for donations to keep them in the latest life-saving equipment. I think very few people give them the amount that’s equal to, say, a basic cable(缆绳) bill.
As a small business owner, I really can’t give these people enough money. And I don’t think our communities do enough to honor these people who risk their lives and volunteer. If you ever lose your faith in people, follow one of these trucks to a disaster and watch who jumps off and what they do. I believe you’ll be amazed by what total strangers are willing to do to protect you.
