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(与直觉不符的), but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released(释放)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 blanke
t.
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. In most scientists’ opinion, the global warming is mainly caused by .

Horton
At first glance, there is little in Horton to attract people. The other nearby towns have much more to offer: Bradfield has its river and historic buildings, while Newtown has shops and entertainment. The buildings of Horton look dirty and unloved. For shops, there is a small supermarket, a few bargain shops, a bakery which, strangely, does not sell bread and a florist which has one stand of sad-looking flowers. Even so, Horton has several advantages over its neighbouring towns.
Firstly, it has a country park. Four thousand years ago, this was an important fort. There are no historic remains here now, but there are wonderful views over the countryside. On sunny weekends you can often see kids out with their parents, kicking balls or flying kites.
There aren’t many job opportunities in Horton, and the roads to nearby cities aren’t really fast, but there are excellent rail links. You can be in London in an hour and a half, and other cities are less than an hour away. That means that parents can earn a good salary and still get home in time to spend the evenings with their families. Houses in Horton aren’t pretty, but they’re functional and cheap. The streets are quiet and safe, and there are plenty of parks and playgrounds. It has a library, three primary schools and a secondary school, St. Mark’s. It is friendly and offers a wide range of subjects and activities to children of all abilities and backgrounds. The town also has a swimming and a sports centre, and the community halls hold regular clubs and events for people of all ages.What is the writer’s main purpose?

After having worked in the University of Maryland for three years, I got a job offer from another university---Lynn University. I left my letter of offer on my present boss's desk, turned around, and closed the door quietly. I was expecting a call from my boss saying congratulations, which would show her approval of my leaving.
In the afternoon, my boss called me, saying, "Can we meet tomorrow? "That was a good signal. The next day, I met with my boss. She said, 'Nicholas, we want you. What do you want?" I said, "Boss, I deserve a significant pay raise this year due to my outstanding performance. I think I need a 10% pay raise next year as a condition for me to stay here." My boss said, "No problem.''
When I left her office, I called Lynn University and told them that I was going to get a 10% pay raise. They had to give me 10% more than their original pay offer in order for me to accept the job.

He said, "The problem is that your colleague will earn less than you, so you will feel guilty(内疚)and uncomfortable. But, I can still give you 5% more than the original offer."
I delivered this massage to my present boss, and she told me that she would give me another 5% pay raise if I promised to refuse this new job offer.

Have you ever heard the saying “All roads lead to Rome”? At one time, this was pretty much true. During the Roman Empire, lots of roads were built in order to move armies, send messages by courier (信使), and make trade easier.
The network of Roman roads was begun in 312 BC. It was demanded that the roads be built strong so that they would not fall down. Roman soldiers, supervised (监督) by engineers, laid down the roads in a special pattern of layers. There were all together 4 layers, which was made of different materials, such as sand, rocks, stones and so on.
Also, Roman roads were cambered(拱形). This means that they were built higher in the middle than on the edges, allowing rainwater to run off, which prevented flooding. We use the same technique in building roads today. The Romans also laid out roads over hills when necessary, setting them down in a zigzag (之字形的)pattern to make the road rise gradually.
All Roman roads had milestones (里程碑), placed every thousand paces (a Roman mile). The milestones told when the road was built, who was emperor at the time, the road’s destination, how far the traveler was from the destination, and how many miles had been traveled since the beginning of the road. This information was a great help to travelers.
Because of their excellence in construction, it really is no surprise that many parts of Roman road still exist today. These roadways are one of the most impressive achievements of the Roman Empire.The following description about Roman roads is true EXCEPT _____.
| A.Roman roads were built by the Roman soldiers directed by the engineers |
| B.Roman roads could prevent flooding using the technique we don’t use today |
| C.Roman roads had milestones that were placed every Roman mile |
| D.Roman roads still exist today as an impressive achievement of Roman Empire |
What information can you find on the milestones?
| A.The builders of the road. |
| B.The materials used in building roads. |
| C.The distance from one city. |
| D.The time spent in building roads. |
The passage mainly ______.
| A.explains the saying “All roads lead to Rome” |
| B.praises ancient Romans for their great achievements |

I am a vegetarian(素食主义者).Many people are quick to think of vegetarianism as strange behavior.I treasure our Earth, and since we only have one, we should protect it and the wildlife that lives on it.But that’s only one of the reasons to be a vegetarian.
Vegetarians may live longer, healthier lives.There is a connection between red meat consumption and various diseases.From an economic standpoint, it requires less land, money and energy to produce foods for a vegetarian diet.While there are many benefits to being a vegetarian, only a handful of those who attempt to adopt this lifestyle succeed.
The most important quality required to be a vegetarian is firmness since surrounded by the temptation of meat, we tend to give up vegetarianism easily.Creativity is almost as important as commitment.It’s easy to tire of eating nothing but salad.But with a little creativity and some soy products, almost any meal can become vegetarian-friendly.
Not everyone wants to be vegetarian.Accepting this is part of being a vegetarian with style.Forcing your beliefs on others is disrespectful.Stylish vegetarians should also be able to turn down a meaty dish politely without annoying their hosts.
Being a successful vegetarian has been easy for me, but it may not be so for others.A common mistake is quitting before your body has adjusted to the change.It can be difficult to keep the lifestyle in the beginning because of temptation.However, it fades over time.Another common mistake is quitting because you’ve been misinformed about the nutritional wisdom of being a vegetarian.That’s why it is vital to be educated.Countless people will tell you that it’s impossible to obtain the nutrients and protein(蛋白质)your body requires without meat, but they are incorrect.People actually need only 44-55 grams of protein a day, and that is easily found in a vegetarian diet.Many meat eaters are consuming three times that amount, which is not beneficial.It leads to diseases.Vegetables can also supply all the vitamins, minerals and nutrients your body needs.However, if you’re still not convinced, you can take a multi-vitamin.According to the passage, being a vegetarian helps ______.
