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 website has been created to provide resources and materials for classroom teachers, reading and resource specialists, speech therapists, parents and students in the area of language arts. Please feel free to download and print anything that catches your eye, but please make sure to leave my name on the poetry and worksheets!

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 |
Alexia was 16 at the time, a student at Westwood High School. The school sponsored a humanitarian trip for 26 students and two teachers to spend 18 days living in a mountain village to build a one-room school. Even though Armato trusted her daughter, the other students and the teachers, she was worried about the side effects from the travel vaccines, possible accidents, and medical care.
Now that Alexia was home, Armato said she saw her daughter’s new maturity, greater confidence and independence. “This is the best thing I ever did,” Alexia said. “The experience was so eye-opening and life-changing. You’re with people who are not as lucky as you are. They live in very poor conditions but they’re so happy and outgoing. You say, ‘My God. I’m taking everything for granted back home.’”
She said they built a one-room school from scratch with no mechanical cement mixers. They used their hands, shovels and basic tools. She and another student lived with a local family in a small village about eight hours outside the capital, Quito. Despite the initial strangeness and knowing only basic Spanish, she said they grew very close and felt like a family.
Every year, groups of students at Montreal High School like Alexia pack their bags and fly off with classmates and teachers to developing countries where they volunteer for a variety of projects.
“Armato’s worries are very common among parents,” says Bill Nevin, a teacher at St. George’s High School. He organizes a humanitarian rip to India to the Sheela Bal Bhavan orphanage and says the three biggest fears families have are health, security and contact.
小题1:When hearing the news that her daughter would go on a school trip to Ecuador, Armato was _______.
| A．proud and happy | B．supportive but concerned |
| C．fearful and nervous | D．excited but puzzled |
| A．having great help | B．using high technology |
| C．ending up in failure | D．starting from the beginning |
| A．Volunteering helps students grow and develop. |
| B．School trips make parents worried about their children. |
| C．Ecuador is the most attractive travel destination in the world. |
| D．Brave Alexia dreams to work in Ecuador one day. |
Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.
Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner.
It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.
小题1:According to the passage, the science of the future is likely to be ________.
| A．electronics | B．biotechnology |
| C．genetic engineering | D．nuclear technology |
| A．as good as wool |
| B．as good as an insect"s body |
| C．better than natural materials |
| D．not as good as natural materials |
| A．to transplant human organs |
| B．to make artificial hearts and eyes |
| C．to produce drugs without side effects |
| D．to make something as good as human skin |
A. the Chernobyl disaster would happen in two years
B. we will never stop using non-renewable power sources biological
C. oil, gas and coal could be repeatedly used in the future
D. power sources would be put into use soon
小题5:What do we learn from the last paragraph?
| A．Biological power will keep all its promises. |
| B．Biological power is cheaper than nuclear power. |
| C．Biotechnology can solve all our future energy problems |
| D．Biological power may not be as dangerous as nuclear power |
