While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (针鼹鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鳄鱼), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
小题1: What can we learn about the platypus according to the text?

Like Xie, 17-year-old Liu Yan at Beijing No. 22 Middle School is also a big NBA fan. “Since early May, I’ve not missed one game in the NBA,” said the senior 3 student.
Basketball is becoming popular in middle schools across the country. And more young players are starting to like the sport. More students are playing the game.
Jiang Hui, a basketball teacher at Beijing No. 2 Middle School, said that 85 percent of the students at this school like the sport. “Students are full of passion for the game,” Jiang’s team won the regional first prize in the 2004 National High School Boy’s Basketball League in march. The league is the first national basketball competition for high school students.
Playing basketball is a good way to exercise. But students also enjoy it for other reasons. For Li Yan, a Senior 2 at Shanghai No. 12 Middle School, basketball teaches him lessons in life. “When I am in a game, I feel more confident about my studies, “ he said. “ It also teaches me to have a good team spirit and to enjoy friendship.”

On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion.About half of the piece is destoryed but the remaining part hits the South Atlantic at 200times the speed of sound.The sea boils and a huge gole is made in the sea bed.Huge waves are created and spread outwards form the hole.The eall of water,a kilometer high,rushes towards southern Africa at 800 kilometers an hour.Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America.the second piece of the comet lands in Argentina.Earthquakes and volcanoes are set off in the Andes Moutains.The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles,San Francisco and Tokyo are completely destroyed by earthquakes,Millions of people in the southern half of the earth are already dead,but the north won’t eacape for long.Because of the explosions the sun is hidden by clouds of dust,and temperatures around the world fall to almost zero.Crops are ruined.The sun won’t be seen again for many years.Wars break out as countries fight for food.A year later,no more than 10 million remain laive.
Could it really happen?In fact,it has already happened more than once in the history of the Earth.The dinesaurs were on the Earth for over 160 million years,Then 65 million years ago they suddenly disappeared.Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out .Will we meet the same end ?

I wasn"t ready to retire. Teaching is in my blood! (My mother always reminded me that when I was little, I dragged the neighborhood kids in to play school whether they wanted to or not!) I still have the strong desire to make a difference for teachers, parents, and students. I"m passionate about the joy of knowing how to read and write and want every child to have the experience of closing a book with a sigh, "Wow, that was a good book!" The only way they can do that is by having the necessary skills and strategies to become independent readers.

This isn"t quite that simple for pupils at Royal West Academy. As if classes and homework weren’t already enough, students are also required to complete a range of extracurricular activities, or ECAs.
The range of ECAs being offered at the school is various, including everything from guitar and jewelry-making clubs, fund-raising marches, to student committees, swimming and tennis.
“I love ECAs. I’m so happy we have them,” said grade 11 student Adrienne, who is a soccer player and member of the graduation committee. “They motivate the students, and they’re a great bonding experience. I think that without them, not half as many students would be joining up for the soccer team.”
Requiring students to complete ECAs is a sign of the times. That’s because young people are preparing for the future in ways that weren’t considered necessary before. This is an era when ECAs are seen as important. Whether it’s for leadership experience, sports, craft skills or volunteer these things are seen as rounding out the individual and improving their future.
ECAs can also help students discover their likes and dislikes. But as the old song says, you can’t always get what you want, especially when so many students are all trying to sign up for the most popular activities.
ECAs can cut into study and homework time if you’re not careful. You really have to get organized or you’ll fall apart.
小题1:The students at Royal West Academy may do the following ECAs except ______.
| A．to play musical instruments |
| B．to raise money for an organization |
| C．to attend sports events |
| D．to have classes discussions |
| A．most of his classmates are interested in football |
| B．one can make many new friends in ECAs |
| C．students get encouraged to join in ECAs |
| D．half of his classmates are unwilling to join in ECAs. |
| A．They prepare the students for their future. |
| B．They can make students get what they want. |
| C．they can help students find their strong points. |
| D．They can reduce students’ learning time. |
| A．ECAs can increase your burden of learning |
| B．you may fall down when playing in ECAs |
| C．too many ECAs may leave you in trouble |
| D．you need to organize other students in ECAs |
In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports --- or other kinds of materials --- could one day contain a color-changing material. It will turn red before a structure collapses(倒塌) or falls apart.
The secret behind the color-changing material is a particular type of molecule(分子). Molecules come in all shapes and sizes, and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms(原子) it contains, and how they"re held together.
To get a rough picture of one way atoms are held together in a molecule, imagine you and your friends standing in a large circle, holding hands. Each person represents one atom, your clasped hands represent the bond, and the entire circle represents a molecule.
The molecule being used to turn the material red is called mechanophore(机械响应性聚合物). When one chemical bond in the mechanophore molecule breaks, the rest of the molecule turns red.
There is a way to get rid of~ the red color: light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers who want to use the color-changer in big construction projects that will be outside, in the sunlight. And if bright light keeps the red color from appearing, then the mechanophore"s warning system will be useless.
Scientists still have a lot of work to do before the color-changing molecules can be used outside the lab. If mechanophore can be used in the real world, they are suggested to be employed in a new kind of paint.
小题1:The first paragraph mainly tells us __________.
| A．the color red is widely used in our life |
| B．how to prevent car accidents |
| C．the color is an important signal of warning |
| D．how to use color red |
| A．tell different materials used in the building |
| B．warn people that the building is dangerous |
| C．make the building more beautiful |
| D．tell people the building is under construction |
| A．the way atoms are held together in a molecule |
| B．how a molecule behaves in an object |
| C．how to play an old game |
| D．how people get along with each other |
| A．Paints | B．Water | C．Poor building materials | D．The bright light |
