Throughout seafaring history, ships and sailors have been lost to storms, accidents and war. Until recently, most of these ships were weak wooden sailing vessel (船只), their skeletons(骨架) quickly eaten away by sea creatures. Now, large vessels made of steel float on the seas. Thousands of these huge ships have been lost in times of war and in times of peace.
The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks(残骸) often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need.
The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae(海藻), but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home.
In warm waters, coral polyps(珊瑚虫) settle on the wreck and begin the process of building a rock-like crust on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck.
Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef (礁石). Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea.
【小题1】Which of the following is NOT TRUE about shipwrecks?

Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory（呼吸系统）and heart diseases.

Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.

So the need to emphasize environmental protection while developing the economy is heard everywhere.

Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.

At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.

China needs to develop its economy and invest(投资) in high-tech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.

What the public wants is a strong and beautiful China. Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's resolution to address the environment issue.

Growing up in the U.S.A., I always wanted to experience another culture. The   1  came when I was 15. After several months of   2 , I was ready to spend the second term of my first year of high school as an exchange student in Australia.
Landing in Perth was one of the most exciting moments of my life. I   3  then that there was no turning back. The family I would live with was waiting for me, and it would be only five days   4  the new school year started.
The Catholic school I   5  was different from my public school back in the States. The uniform code was very strict.

Our   9  were as extensive as our nationalities: we traveled to Sydney, Canberra, Mildura, Coober Pedy, Uluru, Kings Canyon, Alice Springs, Mount Isa, Airlie Beach, and the Cold Coast.
The few weeks we enjoyed together were crowded with   10  . We took a day-cruise on Darling Harbor and visited the Sydney Opera House. We slept in an “underground town”. We walked around the famous Ayers Rock and went sailing on the Pacific Ocean.
At the end of our   11  in Australia, we had three weeks of traveling time to share our stories and help each other deal with leaving. It was   12  that our last day together was filled with tears. We packed our camp, exchanged e-mail addresses, and gathered together for a final good-bye.
