Soon enough, we will lose some of the most amazing sites on Earth!

The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well. All life supported by the oceans will be affected with this shock to their ecosystem. Coral are some of the most vulnerable marine animals and we are already watching whole reefs disappear. The Great Barrier Reef in Australia is no exception and will continue to shrink as the temperatures rise! These reefs are some of the best in the world for diving, but they will soon disappear!

Venice---Sprawing across(橫跨)hundreds of small islands in Northeast Italy, Venice is at extreme risk of sinking into the Adriatic Sea. Rising sea levels are in fact a serious threat to many coastal cities located at sea level. Lucky for us, however, Venice is developing a series of sea walls to protect the city in times of high tide.

Glacier(冰川)National Park---Glacier National Park was once covered by over 150 glaciers, but by 2005 it only had about 27! Located in Montana, Canada, this park is over a million acres and has a huge plant and wildlife population. As temperatures rise, the glaciers and ice melt, which will upset the ecosystems sustaining over a thousand plant species and hundreds of animals.

The Amazon---The cause behind the disappearance of these fantastic places ultimately comes down to humans. Our expansion usually requires cutting down forests for land, fuel and materials, but rarely considers the consequences. These forests are sources of food and medicine for just about everyone on the planet!

What will happen if we lose these valuable places and beautiful destinations?!

1.According to the text, what is causing coral’s death?

A. Rising sea levels

B. Humans’ diving activities

C. Rising sea temperatures

D. The shrinkage(縮小)of their habitats

2.What can we infer from the part of “Venice”?

A. Venice is the only coastal city of Italy

B. Many places are in the risk of sinking below the sea level

C. Venice will never sink because of the protection of sea walls

D. Italy consists of hundreds of small islands in the Adriatic Sea

3.What can we learn about Glacier National Park from the text?

A. It covers a large area in Montana

B. It is covered by over 150 glaciers

C. Plant species and animals in it have died out

D. It doesn’t support any living thing for its cold

4.Which site’s shrinking reason differs from the other sites?

A. The Great Barrier Reef B. Venice

C. Glacier National Park D. The Amazon

I would always remember that day. When I was 14，all I wanted was a unique necklace with my name carved. It was the “in” thing and it seemed every girl except me had one. On my 15th birthday, my Mum gave me a beautiful necklace with my initials(姓名首字母) carved into it. I was in heaven.

What made it even more special was that it was about the only thing that wasn’t being “replaced”. We’d been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the “new” stuff(東西) we got was really just to replace what we’d lost. But not my necklace. My necklace was new.

Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

Years passed, and a couple of moves later, I was visiting my parents’ when Mum told me that she had something for me. It wasn’t my birthday, nor was it Easter or Christmas or any other gift?giving occasion. Mum noticed my questioning look. “You’ll recognize this one,” she said, smiling.

Then she handed me a small ring box. I took it from her and opened it to find my beautiful necklace inside.

The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom，they found the necklace. As it had my initials carved into it, they realized who owned the necklace. They’d had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

1.The underlined word “in” in the first paragraph probably means “________”．

A. available

B. fashionable

C. practical

D. renewable

2.When she got the necklace back, the writer was about ________.

A. 30 years old

B. 28 years old

C. 15 years old

D. 14 years old

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

A. The writer lost her necklace in the morning when she took it off.

B. The writer never stopped looking for her necklace.

C. The writer’s ring was cleaned up by the new house owner.

D. The writer’s family moved several times during her growth.

4.What would be the best title for the passage?

A. My New Necklace

B. Lost and Replaced

C. Lost and Found

D. A Beautiful Necklace

Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago. 1.

The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses. 2. So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．3. However, a change in food is one of the main differences between life in ancient times and that of today.

Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains. 4..We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

5. But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

A．Stone Age people lived a simple life.

B．But today, we enjoy having a lot of these.

C．In that case, they would live much healthier.

D．Ancient people also got lots of physical exercise.

E．These new sicknesses were not known in ancient times.

F．People today probably don't want to live like our ancestors.

G．Modern people used to suffer from "diseases of civilization".
