The volcano is one of the most surprising frightening things of nature. Maybe you have seen pic??tures of these " fireworks " of nature. Sometimes when a volcano erupts, a very large wall of melted rock moves down the side of a mountain. It looks like a " river of fire". Sometimes volcanoes ex??plode, throwing the melted rock and ashes high into the air. But where does this melted rock come from?

The earth is made up of many layers (层). The top layer that we see is called the crust. Under the crust are many layers of hard rock. But far, far beneath the crust the rock is so hot that it is soft. In some places it even melts. The melted rock is called magma. Sometimes the magma breaks out to the surface through cracks (裂缝) in the crust. These cracks are volcanoes.

Most people think of mountains when they think of volcanoes. But not every mountain is a volca??no. A volcano is simply the opening in the earth from which the magma escapes. The hot magma, or lava as it is called, cools and builds up on the surface of the earth. Over thousands of years, this pile of cooled lava can grow to be very, very big. For example, the highest mountain in Africa, Kilimanja??ro, is a volcano. It rises more than 16,000 feet above the ground around it.

8. The underlined word "erupts" means ______.

A. moves down   B. breaks away    C. builds up        D. suddenly throws out lava

9. Which words in the passage have the same meaning as "melted rock"?

A. volcano and crust                  B. crust and hard rock

C. magma and lava                  D. volcano and magma

10. Which is the correct order of the layers of the earth (beginning with the top layer)?

A. crust — hard rock — magma — soft rock

B. crust — hard rock — soft rock — magma

C. agma — soft rock — hard rock — crust

D. volcano — cracks — magma — crust

11. The best title of the passage should be______.

A. The Volcano         B. Kilimanjaro Volcano   C. The Mountains   D. The Melted Rock

Diamonds may be forever. But what’s a girl to do when she gets dumped (失恋) or divorced (离婚) and those rings, necklace and love gifts lose their emotional (情感) sense?
Help is just a click away on new Web sites that provide an outlet for selling jewelry(珠宝) from past relationships, sharing break-up stories and helping broken hearts heal (愈合).
“You go through a divorce. What do you do with that ring? Maybe you have a child you can pass it on to. Maybe you don’t. It just sits there, ” said Megahn Perry, who with her stepmother (继母) Marie Perry runs www.exboyfriendjewelry.com.
Three months after its start with the slogan(口号) “You Don’t Want It. He Can’t Have It Back,” the web site has 3,000 registered users and more than 600 postings of rings, bracelets and earrings for sale—all with a personal tale attached.
As one woman posting a diamond ring for $3,500 wrote:
“Beautiful ring came with a wrong man. Decided to sell to regain the money that I spent finishing payments on the ring that my ex didn’t.”
The idea was born when Megahn Perry, a Los Angeles actress and writer, was looking for a safe place to sell a wedding set after a divorce and realized others might have former boyfriends’ jewelry with memories(记忆) that make them too painful to wear.
The local pawn shop(当铺) proved an unattractive choice. So she teamed up with her stepmother Marie, researched the market and found a gap in it.
【小题1】 The passage is mainly about _____.

A.how a web site is set upB.how sad the love stories are

【小题4】Who set up this website?

C.Megahn and her stepmother.D.Megahn and her exboyfriend.

Have you got a Facebook account? Are you thinking of getting one? Jamie Simmonds has just signed up. Let’s see how she’s getting along.

My Diary

MONDAY: I’m officially a Facebooker. I find a few people I used to know and I’ve soon got seven friends. I’ve never felt so popular! I wonder if my old university flatmate Steve is on here…What do you know! He is! Maybe Facebook has its uses.

TUESDAY: I’ve received lots of nice welcoming messages on my wall. Later, I meet up with Steve for a drink after not seeing him for five years. We get on really well! Then, he uses his Facebook app for iPhone to suggest me as a friend to some other former classmates. Some of them even come to the pub and it’s just like old times – possibly a bit too much like old times. During the night, photos are uploaded to Facebook.

WEDNESDAY: Disaster! My mum’s on Facebook! Has she seen the photos of me dancing on the table from last night? Has she shown them to dad? Oh. And I have a friend request – mum again!

THURSDAY: There’s a message from my boyfriend, “so, it’s over then, ;is it?” Evidently I haven’t changed my settings to show I’m “in a relationship”, and I haven’t even added him as a friend. Ah, well, I wonder what my ex-boyfriend is doing… Whoops! I accidentally type his name into my status box instead of the search ‘ and now every one can see it on their news feed.’

FRIDAY: Time to update my status:“Work is boring. Can’t wait for the weekend!” Yeah, that about sums it up. Oh, look, I’ve received a comment! Someone must feel the same way. Lots of my friends now“like” this status.

SATURDAY: Good news! I’ve got 100 friends But wait! Someone’s “un-friended” me! I look through my “friend list” to try to work out who it was. Why did they do that? Am I really such a terrible person? I never knew Facebook could be this cruel.

SUNDAY: Wake up. Check my Facebook page. Make coffee. Check my Facebook page again. Get ready to leave. Change my mind and check my Facebook page … again. I am becoming addicted to it! I think it’s time to end it all before it takes over my life. I delete my account. Back to good, old, simple e-mails. Oh, look, I’ve got a message: A friend invited you to join Twitter. . .

In July 2010, Facebook had more than 500 million active users. The average Facebook user has 130 friends. Facebook is translated into more than 70 different languages.
