Hanging Gardens of Babylon(巴比伦空中花园)
The Hanging Gardens of Babylon were built in the 7th century BC and are considered one of the Seven Wonders of the Ancient World. The Hanging Gardens of Babylon were amazing not only because of their beauty, but also because of their location.
In the 7th century BC a king named Nebudchadnezzar II created the gardens as a sign of love for his wife, Amyitis. According to legend, Amyitis, the daughter of the king of the Medes, was homesick. She missed the green hills and valleys of her homeland.
Upon marrying Nebudchadnezzar II, Amyitis moved to the ancient chief city of Babylon. The area was in the Mesopotamian desert, and the climate there was totally different from where she had left. So the new queen was very sad about the flat and the sun-baked desert. To make Amyitis happier and more comfortable the king decided to build her a series of magnificent gardens.
Many think of the gardens as an otherworldly creation that hung in the air somehow. But experts agree that the gardens were actually built on a mountainside, rather than actually “hanging”.
The hanging Gardens of Babylon are famous. Stories of them spread throughout the ancient world, and ancient writers recorded a large number of descriptions of the gardens, but some wonder whether this paradise of the past ever existed. There are no historical records of it except stories. Whatever may happen, even the idea of the Hanging Gardens of Babylon is amazing. They were essentially impossible to create because of the climate, but they were kept in the minds of many as a botanical beauty created in the middle of unattractive desert scenery.Hanging Gardens of Babylon are considered one of the Seven Wonders of the Ancient World, aren’t they?

Did you know that a new weblog is being created each second? Many of these bloggers are teenagers. While their parents wrote in a diary to express their emotions, or shared their interests by spending time with friends, teens are now using blogs instead. In fact, in the US, one in every five school-aged teens has a blog. Most of these are just chatter, some are funny or clever, but a few have become Internet success.
For example, Chloe Spencer’s blog ‘Neopets Fanatic’ gets around 300,000 hits per month. When Chloe was 15, she started the blog out of her strong liking for Neopets, a kind of pet website. One reason her blog has so many visitors is because she gives instructions and tips for the popular pet site.
Then there is Tavi Gevinson’s blog ‘Style Rookie’. It is said to get 1.5 million hits per month. Tavi, who started her blog when she was just 12, puts up her photos of her own clothes online as well as designers’ collections. Tavi’s blog has caught on because she knows a lot about style for someone so young, and she is not afraid to try out unusual clothes or see things in a different way.
Blogs like these are interesting, but they only become really popular after better-known websites link to them or they get noticed by the media(传媒). For example, Tavi’s blog became an overnight(一夜之间) success after being written about in The New York Times. Popular blogs can even earn money, usually from advertisements that companies pay to put up on the bloggers’ sites.
So for some, blogging is just a recreation(消遣), but for others, it can become a source of income and even a full-time job! Teens nowadays ________ than their parents did.
A.have more ways of communication |

C.write in diaries more often |

In today’s world many people seem to be hungry for money. Money does have its most useful effect on the poor. But even if a person has already got plenty of money, he can’t get everything.
If money were everything, all millionaires would have real love, true friendship, good health and a long life. However, this is not always correct.
Since the beginning of time no three words have ever invited more pleasure than “I love you”. But can love be bought? I’m afraid not. Love means to give, not ________ (78). To every person, health and a long life are probably the best things. Well, can health and a long life be bought with money? The answer is “No”.
(79) Of all the longest living people in the world, few of them are millionaires. True friendship can’t be bought, either. In a word, where money is dreamed too much, it can cause brothers to quarrel, marriage to end, lovers to hate, and strangers to fight. No matter how much money you have, it is still not enough to make a happy person if you have no one to laugh with, no one to cry for.
