When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet”when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet”quickly goes away. When other ants detect the“dead”chemical without the“not dead yet”chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the“Wait—I'm not dead yet”chemical, other ants left the treated ant alone. Choe believes this behavior shows that the“not dead yet”chemical overrides the“dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining“dead”chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Sydney is Australia’s most exciting city. The history of Australia begins here. In 1788 Captain Arthur Phillips arrived is Sydney with 11 ships and 1,024 passengers (including 770 prisoners) from Britain. Today there are 2.5 million people in Sydney. It is the biggest city in Australia, and one of the most beautiful cities in the world.
There are over 20 fine beaches close to Sydney. Its warm summer climate and cool winter have made it a favorite city for immigrants(移民) from overseas. There are three things that made Sydney famous –its beautiful harbor, the Sydney Harbor Bridge, and the Sydney Opera House.
But there are many more interesting things in Sydney: beautiful shops and restaurants, for example, rows of interesting old houses built everywhere in the 19th century. Summer or winter, day or night, Sydney is an outdoor city.
Some Americans think it is very British. Some British visitors think it is like America. There is some truth in both these opinions, because Sydney takes from both the Old World-Europe, and the New World – America, and makes it into something that is neither British nor America but truly Australian.

I have recently been diagnosed with an addiction-to coffee. And I am not alone. This is a problem among Americans of all ages. The coffee shop has become a social feature in our culture. Its appealing smell, cozy and inviting atmosphere are difficult to resist, especially if you struggle with an addiction like alcohol.
But, when you look past the leather couches and coffees named after European cities, all you'll find is coffee, milk, and a little sugar. Anyone can buy a Coffeemaker and a container of Coffee Mate and try to create the same drink as a coffee shop does. The only difference between your homemade coffee and coffee shops is that they put it in a cute cup and throw on some whipped (泡沫状的) cream to convince us that we are treating ourselves to a worthy relief from the fast pace of everyday life. And we believe them, silly for the idea that drinking their coffee improves our quality of life.
So, next time this "white chocolate" begins echoing in your mind, you'll have to make a decision: Will you continue to be one of the millions of brainwashed Americans who live for their next trip to a coffee shop, or will you just walk away and ignore it? My advice is -- dare to resist and just say no.
61. The major features of a coffee shop are the following EXCEPT its _______.
A. attractive smell                                      B. comfortable surrounding
C. pleasant atmosphere                                D. alcohol-like addiction
62. The coffee from coffee shops differs from homemade coffee mainly because it _______.
A. is mixed with whipped cream                B. is usually served in a cute cup
C. offers a feeling of precious relief               D. can improve the quality of life
63. "White chocolate" in the last paragraph probably means _______.
A. coffee with cream                             B. chocolate with coffee
C. brainwashed Americans                      D. addiction to shop coffee
64. The author's attitude towards "white chocolate" is _______.
A. positive             B. uncaring          C. negative             D. optimistic

Imagine living in a city made of glass. No, this isn’t a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs.

The reef you’d be looking at is made up of glass sponges(海绵). But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old.

When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms.

Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane(甲烷) gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges.

“It’s a new ecosystem we know nothing about,” said Dr. Johnson.

The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a “kindergarten” by scientists.

Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home.

The Washington coast isn’t the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were stunned to see it.

1.Which of the following is the best title for the passage?

A. Man-made cities under the sea B. The world under the sea

C. Glass “cities” under the sea D. Creatures under the sea

2.It can be learned that the glass reef _______.

3.Which of the following is TRUE according to the passage?

A. The sponges must feel soft.

B. Silica comes from animals’ body fluid.

C. Methane is harmful to glass sponges.

D. Glass sponges depend on the bacteria for a living.

4.Why did scientists call the glass reef a “kindergarten”?

A. Because the babies of many sea creatures grow well there.

B. Because thousands of children visit it every year.

C. Because it is crowded with snails and rockfish, etc.

D. Because all the species call the reef home.

5.What does the underlined word “stunned” in the last paragraph mean?
