Traveling Light
By Joel Hanson
Well I was doubling over the load on my shoulders
Was a weight I carried with me everyday
Crossing miles of frustrations① and rivers a raging
Picking up stones I found along the way
I staggered② and I stumbled③ down Pathways of trouble
I was hauling④ those souvenirs⑤ of misery
And with each step taken my back was breaking
Till I found the One who took it all from me
Down by the riverside
（Down by the riverside)
I laid my burdens down
Now I’m traveling light
My spirit lifted high
（I found my freedom now）
I found my freedom now
And I’m traveling light
Through the darkest alleys and 轻装前行
乔伊·汉森
如双倍的重量压在肩上
感觉自己每日在负重前行
走过挫折的道路，穿越伤痛的河流
不断俯拾寻找路旁的卵石
我摇晃着，坎坷前行
眼前是充满烦恼的路
我拖曳着这些痛苦的负重
每一步都感觉后背要被压垮
直到我发现了他
卸下了我全部的负重
走在河滩上
我卸下了负重
现在我轻装前行
我的精神在升腾
我找到了自由
我轻装前行
在黑暗的隧道和孤独的山谷里
我曾背负那些沉重的锁链
充满不安和恐惧
可现在一句简单的话语,锁链已打开
他引导我来到了再也不要流泪的地方
走在河滩上
我卸下了负重
现在我轻装前行
我的精神在升腾
我找到了自由
我轻装前行

up ＆ Lesson 1-Comprehending
Can we take the heat?
In the last few decades①， scientists have reached consensus② and reported that human be ings are causing changes in the Earth’s climate—something previously seen as beyond our control③。

They claim④that in the last 50 years， gases pumped into⑤ the Earth's atmosphere by the factories and vehicles have been speeding up⑥ the process of global warming and affecting our climate. Looking ahead⑦, scientists believe that global warming could be one of the biggest environmental problems facing the 21st century⑧。

But what exactly is global warming， why is it seen as⑨ a danger， and how is it relevant⑩ to our lives?
Global warming refers to⑪an average increase in the Earth’s temperature that, in turn⑫，leads to⑬climate change. Scientists found that the temperature of the Earth is controlled by greenhouse gases such as carbon dioxide which trap heat from the sun in the Earth’s atmosphere⑭. Without these naturally occurring gases， the sun’s rays⑮ would bounce⑯ back into space leaving the Earth cold and impossible to live on⑰。

When the presence of these gases in the atmosphere increases, however, more heat is trapped⑱and the Earth’s temperature rises。

我们受得了这么热吗？
在过去的几十年里，科学家们一致认为，人类正在造成地球气候的变化—-这是一种原来被认为是超出我们控制能力的现象。

他们声称，在过去的50年里，工厂和车辆排入地球大气层中的气体加速了全球变暖的进程，影响了我们的气候.展望未来，科学家们认为全球变暖可能是21世纪面临的最严重的环境问题之一。

但是，确切地说，什么是全球变暖？为什么把它视为一种危险？它如何与我们的生活相关呢?
全球变暖指的是地球温度平均增长，继而导致气候变化。

科学家们发现地球的气温受温室气体如二氧化碳的控制，这些气体能将来自太阳的热量留在地球的大气层里。

如果没有这些自然产生的气体,太阳光线将会被反射回太空中去,地球将处于寒冷之中，生命也就不可能在地球上存活.然而,当大气层中的这些气体的浓度不断增加时,更多的热量被留在地球，造成地球气温上升。

Over the last 100 years， the global average temperature has increased by 1°F and many experts insist⑲ that the blame for this global warming can mostly be pinned on⑳human activities. As a result of increased industry，agriculture , the cutting down of forests， the increase in transport and the burning of fuels, nearly 6 tonnes of carbon dioxide goes into the atmosphere every year for every one of the Earth’s 6 billion people。

The amount of carbon dioxide in the atmosphere has risen by more than 30% in the last 250 years with half of this increase occurring since 1960。

Given this data, it seems that the link between human activities and rising global temperatures is not merely a coincidence 。

A temperature increase of 1°F may not sound like a lot, but if we continue to produce carbon dioxide and other gases in such huge quantities , we are condemning life on Earth and should expect severe consequences . Recent
reports warned that global warming will cause terrible climate changes including more frequent flooding， heat waves and droughts 。

Serious diseases will spread and industries that rely on nature such as fishing will be badly affected. Increased temperatures will also cause the polar ice to melt, raising sea levels and flooding many islands and cities✍。

How can we stop these disasters from happening?
Governments all over the world have a responsibility to reduce the amount of carbon dioxide which their countries are producing✌. If less carbon dioxide goes into the atmosphere，global warming will slow down 。

This is no easy task, however, and some governments, for example，the USA's federal government, express reservations about whether global warming is really caused by human activities☜。

Many people believe that they are simply not prepared to sacrifice☞ the amount of money they make from industry to save the Earth。

But why wait around for governments to take action☝? Experts advocate☟that each person play their part✋。

They suggest making small changes like taking public transport，recycling☺， using low。

flow shower heads, and buying light bulbs that use less energy。

Even simple things like using recycled paper or switching off the lights when you leave a room can help。

If we add up☹ all these small changes made by everyone worldwide ， they won’t be such small changes。

They could be the changes that save our future。

After all☠, there’s no substitute for our Earth。

It’s all we've got to live on .

在过去的100年里，全球的平均温度上升了 1 华氏度,许多专家坚持认为，在很大程度上，人类的活动是导致全球变暖的重要原因.随着工业、农业规模的不断扩大，成片成片的森林被砍伐,交通运输日益频繁，燃料消耗不断增长，每年有接近6吨的二氧化碳被释放到供地球上60亿人中的每一个人呼吸的空气中。

在过去的250年里，大气中的二氧化碳含量已经增加了30%以上，而其中的一半是在1960年以后增加的。

考虑到这一数据,人类活动与正在上升的全球温度之间的关联似乎不仅仅是一个巧合。

气温升高1华氏度也许听起来无关紧要，但是如果我们继续制造如此多的二氧化碳和其他气体，我们将毁灭地球上的生命，后果将非常严重.近期的报告警告说，全球变暖将导致气候急剧变化,包括更加频繁的洪水、热浪和干旱。

严重的疾病将四处扩散，自然产业如渔业将会受到严重影响。

温度升高还会引起极地冰山融化,海平面上升,从而淹没许多岛屿和城市.我们怎样才能防止这些灾难发生呢？
世界上的每一个政府都有责任降低自己国家二氧化碳的排放量.如果少向大气中释放二氧化碳，全球变暖就会慢下来。

然而，这是一项非常艰巨的任务。

一些政府,例如美国的联邦政府，对于全球变暖是否真的是由人类活动引起的仍持保留意见。

许多人认为他们只是不愿意牺牲自己从工业中赚到的钱来拯救地球。

但是为什么要等待政府来采取行动呢？专
家主张每个人都发挥作用。

他们建议做一些小的改变，比如搭乘公共交通工具，回收利用,使用节水淋浴喷头，购买节能灯泡。

甚至是一些非常简单的事情,如使用再生纸或离开房间时关上灯，都会有用。

如果把全世界每个人做的小改变累加起来，它们就不是小的改变了，而是拯救我们未来的改变。

毕竟,我们的地球是不可替代的,它是我们必须赖以生存的全部.

There are a few fresh book.group ideas for improving your gatherings。

Start one of your own or join one that surprises and delights you。

The Under.One。

Hour。

of.Reading Club
Joanna Goddard always wanted to join a reading club， but she knew she was a slow reader and that she’d never finish a 300。

page novel。

Her idea? Start a club based on something that takes only 45 minutes to read。

She says, “Articles are real。

life，which makes them easier to relate to.”And the ideas discussed in those articles from magazines tend to be controversial，which leads to lots of fun， even heated debate。

The Choose­Your.Own。

Novel Club (with a Side of Pizza）
If you’re the kind of person who buys many novels but you’re still trying to finish the book you started in 2004, this club is for you. Tiffany Sun just couldn't find the time, energy or willpower to read. She and a friend decided to approach reading like “dieting， where you have a friend who keeps you on track with your eating plan, because she's doing it, too”. Once everyone finishes three books，the group will go out for pizza to talk about their choices and experiences. “Frankly speaking，without the pizza，I don’t think any of us would make it all the way to ‘The End’ month after month,”Sun says。

The Club That Shares the Same DNA
When your family are on holiday together， try presenting each member with the same book. As the family hang by the fire at night or stay around the coffeepot in the morning，they’ll read。

At night， over dinner， the group will also have something relatively safe and attractive to discuss， as opposed to talking about exactly how dry the turkey is。

【解题导语】本文是一篇说明文，介绍了几个别具一格的读书俱乐部。

1．How does Joanna Goddard solve her reading problem?
A．By reading short articles.
B．By changing her reading club.
C．By making herself more patient.

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate。

Without the forest cover，these areas would reflect more heat into the atmosphere， warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world。

In the past hundred years,humans have begun destroying rainforests in search of three major resources: land for crops,wood for paper and other products，land for raising farm animals。

This action affects the environment as a whole。

For example，a lot of carbon dioxide in the air comes from burning the rainforests。

People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit。

There are two main reasons for this. Firstly,when people cut down trees,generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply。

Rainforests are often called the world’s drug store。

More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than 1％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking（萎缩的） rainforests。

【解题导语】本文讲述了热带雨林在人们生活中的重要作用。

号召大家保护雨林，不要乱砍滥伐。

4．Rainforests can help to adjust the climate because they ．

Mexican weddings are deep in customs and traditions. Many customs still repeat in Mexican weddings as far back as seven centuries。

Weddings are usually held in a Roman Catholic Church. The bride and groom stand or kneel at the church。

Family and Godparents play a leading role in the ceremony.
In Mexico, the couple choose those who would be “mentors” for themselves during the wedding。

They are usually people who have played a powerful role in the life of the bride and groom or their parents。

Sometimes, in most popular houses or towns, the couple also c hoose the “sponsors” who can support them and pay partly for the wedding。

Mexican brides have various choices for their wedding dress。

Wedding dresses can vary from simple cotton silk to embroidery（刺绣) fabric。

But some brides prefer a traditional wedding. There is a tradition where the bride sews three ribbons， yellow， blue， and red in her underwear for good luck. The ribbons are meant to ensure food, money and passion in the coming years, and yes, no one else can see，but it is a part of the traditions and preparations。

In more modern families, the bride would only wear a blue color.
In a tradition dating back to ancient Rome， the groom gives the bride 13 coins at the ceremony。

The gift of the pieces is blessed by the priest（牧师）in Catholic ceremonies and i s supposed to represent the groom’s promise to support his wife throughout their life together and the acceptance means her promise to take care of him。

In most traditional cities， the wedding menu may include chicken or pork，fresh dishes of rice, and beans。

But menus can get very fancy if the budget allows. In weddings and social events in the Huasteca region， a large tamale called zacahuili is cooked overnight in a hole in the ground and then distributed between 50 and 150 people。

It is made of corn powder， butter，peppers and the ground pork.

Because of work，school or family responsibilities, many people have no time to take an extended vacation. 1. Therefore, there is one popular choice for them-a mini vacation。

A mini vacation is a one to three days' getaway. Unlike the standard vacation，it doesn't require weeks of planning and needn’t cost much. 2. You will have the chance to get your mind off work and take a break from your regular routine。

Quite often, a mini vacation is scheduled around an official holiday or school break, in order to avoid taking too many personal days off from work or having to pull children out of classes. A typical long weekend could start
after work or school on Friday and end the night before a regular schedule comes again. Time is really limited。

3.
An overnight trip to an amusement park nearly could be considered a mini vacation。

It has advantages。

People can enjoy an inexpensive vacation from the stresses of work or school。

4. Many people are surprisingly unaware of interesting attractions located within a few hours of their hometowns，but local hotels and visitor centers often have lots of informational booklets on local attractions。

5． It includes minimal(最少的) packing and little gas. Other costs may include entry fees of the attractions，hotel reservations，meals and souvenirs. Some vacationers on limited budgets may be able to stay overnight with relatives or friends。

They can also save money by purchasing inexpensive meals at local stores or fast food restaurants。

A．Stop at any scenic spot that looks interesting。

B．A mini vacation generally calls for less money。

C．But it will still provide the same basic content of any trip.
D．A mini vacation is also sometimes annoying to prepare for。

E．So people usually look for destinations within a few hours of their homes。

F．Besides，they are still able to drive back home for emergencies if necessary。

G．Others may have the time, but not have the money to travel for a week or longer。

day sail across the Drake Passage to Antarctica.
I have been looking forward to this expedition（探险） for a long time。

We’ll be flexible to operate in the best light of the day and to explore the places we choose。

Being the first expedition of the season means we would encounter really fantastic ice and snow conditions on the Peninsula. If you follow my blog， then you will know I’ve written a series of long articles on How to Choose a Photographic Expedition to Antarctica over the past months。

Everything about this expedition has been designed with the photographer in mind first and foremost。

I like to do a post of what equipment I am taking with me on an expedition。

After much soul searching，and a lot of hesitation, I have decided not to take my underwater housing and Polecam system with me on this expedition。

Simply put，I don't feel I have enough experience with the underwater system now to maximize any opportunities to present them。

Antarctica is a difficult place to operate and photograph， and trying to work with equipment with which you are unfamiliar is at best problematic and at worst a complete waste of time。

It would certainly result in missing other opportunities。

Underwater work in Antarctica is simply going to have to wait until such time as I have become more familiar with the housing controls and the slight difference in working underwater。

Without the burden of the underwater equipment, I can focus on work on land and bring a good range of equipment to work with。

【解题导语】本文是一篇记叙文。
