Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming． Countless recent reports from the world’s leading scientific bodies have said the same thing． For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity．”
The idea that humans could change the planet’s climate may be counter-intuitive（與直覺不符的）, but the basic science is well understood． Each year, human activity causes billions of tons of greenhouse gases to be released（釋放）into the atmosphere． As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket．
Of course, the planet’s climate has always been changing thanks to “natural” factors（因素） such as changes in solar or volcanic（火山的）activity, or cycles relating the Earth’s going around the sun． According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes．
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question． As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without． That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty．

【小題1】 In most scientists’ opinion, the global warming is mainly caused by ________.

As I sit at home thinking about my upcoming adventure and the things I need to bring, it makes me even more excited to begin my travel. I will be making my way around the world.
The first places on the list are Andalusia and Africa in the book The Alchemist. I will need to pack a lot of things and make sure I have enough money to provide myself with food and enough to drink. The Sahara desert is always hot and requires plenty of water.
Next I will head to Mexico in the book Born to Run, where I will meet the Tarahumara Indian tribe(部落). I will need to get into shape and do some jogging(慢跑) if I want to keep up with them. I will have to pack my running shoes, though, because the Tarahumarans have mastered the art of running on the tough land.
After Mexico, my journey takes me to the Egyptian desert in the novelThe Paris Vendetta. There I hope to help uncover an ancient conspiracy (陰謀) that goes back centuries. Just like my trip to Andalusia, I will have to make sure I have plenty of water. Packing the Camelbak products seems like the best idea, so I will have enough on hand at all times. I expect this adventure to be quite interesting, and I am very excited about it.
Lastly, I will make my way back to America in the book Shattered: Struck Down, But Not Destroyed. This makes me feel excited because like the main character in the book, I also wanted to become a professional athlete when I was younger. For this trip, I will go with an open mind and hopefully meet some friends along the way.
I am ready to embark on my adventure of traveling, and I cannot wait any longer!

【小題1】 In most scientists’ opinion, the global warming is mainly caused by ________.

My family moved into our home nine years ago and we spent a lot of time and energy in the yard to get it looking like it does today. We live on a corner and the yard is   41   by a rock wall. We call this area our “rock garden”.

Last summer, I found a tiny little   42__in the yard that I could not immediately identify. I knew I didn’t plant it. We   43   to let it continue growing until we could   44   what it was.

Weeks passed and as I made my way back to the   45   plant, it appeared to be a sunflower. I decided to treat it with care and   46   the weeds around it. As I pulled rocks from the area to get to the weeds, I noticed something   47  . The sunflowers had not   48   where I saw the stalk (莖) began. It   49   had begun under a big rock and grown under and around it to reach the   50  .

That’s when I   51   that if a tiny little sunflower didn’t let a big rock stand in its   52   of developing, we too have the capability of doing the same thing.   53   our environment begins to see that we believe in ourselves like that little sunflower, we can   54   the same nutrient as well.

  55  , we need to believe in ourselves knowing we have the capabilities in   56   our desires. Like the sunflower, it knew it had the capability to overcome its obstacle because it   57__ in the universal truth and had   58   that it would succeed.

Stand tall like the sunflower and be   59   of who and what you are and the environment will begin to support you. You will find a way to go under or   60  your big obstacle in order to reach your desires.
