One day when I was walking home, I had heard a noise behind me. It was a pretty dog, and he followed me home. Dad was surprised, saying she looked as the Smiths’ pet dog. Realizing she was very tired, I gave her a bath but kept her company until she felt comfortably.
A big surprise came next morning, when I found her with four little cute puppies! I was in great excite. Before long Dad led Mrs. Smith in, that thanked us for taking care of the dog. She asked whether I wanted to keep one of them — I was thrilling for the sudden joy!

When you read a book, you’ve probably noticed that a brand new book has a rather special smell, 1. differs from that of an older book. Where does 2. come from? Three sources — the paper, the ink and the glue.
Around 200 AD, the Chinese first came up with paper, one of the greatest 3. (invent) in the world. It is made 4. wood. The wood must be processed with various chemicals 5. (add) to change its structure, to remove acid and to whiten the paper. Then comes the ink — there are many kinds. Some fade with time, while others get 6. (dark) than years ago. Finally, different glues are used to join the sheets together and attach the covers, whether hardcover 7. paperback. Therefore, you can smell different chemicals 8. (come) out of your new book.
Today, the forms of books 9. (change) dramatically since the birth of eBooks. They might be 10. (convenience), but you can’t give your copy to others as a present, and they don’t smell as nice.
My daughter loved dance, until she didn’t. After an _________ first year, I noticed her interest fading week by week. Then, one day, she slowly walked to me before class and asked if she could just _________ it.
My first reaction was to _________ her to “finish what you start”. _________, sticking with something difficult can teach perseverance (毅力), discipline and confidence. But watching my first-grader _________ herself into each ballet position, I started to question how much _________ that “blanket advice” made. Is it really in my kid’s best _______, or even practical, to make her stick to every commitment through until she reaches a bitter _______? What if there are different but _________ valuable qualities, which can be gained by ________ the things that are not right for her?
With the winter show approaching, I realized she needed to either __________ her class or commit herself to it. After a few days’ consideration, she __________ dance wasn’t for her — a choice I __________. Quitting is never a black-and-white issue. Sometimes, it means ________ a barrier in your way to love something else. In my daughter’s case, ending dance made space for her new hobbies, such as horseback riding and Girl Scouts. She’s into them for now, but it is okay if that __________ changes.
As adults, we are accustomed to __________ the power of saying yes, but what about saying no? The ability to recognize when something isn’t an __________ investment of our time or energy is also important. As my daughter gets older, I want her to feel confident to __________ something that’s no longer meeting her needs. She shouldn’t be held back by the thought that she must __________ something at any cost __________ because she has started.

Imagine you are on a long car trip. It is night and you take a wrong turn onto a dark country road. With a sinking feeling, you realize that you have no idea where you are.
1., and the answer is written in light. A shining compass face, with north, south, east and west at the four points, and a big needle are pointing at north. What a relief! You turn your car around and head in the right direction guided by the sky.
For migrating birds, finding their way over long distances through the darkest nights is their second nature. 2. — directions written by light and magnetism (磁力). Some birds journey thousands of miles in their twice-yearly journeys. 3., like mountain ranges and rivers, to help decide the directions; but birds may also navigate using the stars, and by sensing — or even “seeing” — the Earth’s invisible magnetic field.
For many years, scientists have been studying what’s behind the strong ability of migrating birds to find their way to their winter and summer homes. Here is one thing that they agree on. 4.. This compass leads them to make their very first autumn flight in the direction that has been long-travelled by the rest of their species. 5..
A.Then you glance up at the sky
B.So birds are born knowing which way home is
C.They do it in part by reading directions in the sky
D.Magnetism is important for all animals, especially birds and fishes
E.When they’re on the way, they take the advantage of familiar landmarks
F.Migratory baby birds are already equipped with a kind of present inner compass
G.In birds, migration means two-way journeys — onward journey and backward journey
Rivers are the veins of the Earth, transporting the water and nutrients (营养物) needed to support the planet’s ecosystems, including human life. While many nutrients are essential to the survival of life, there is one element transported by water in rivers that holds the key to life and to the future of our planet — carbon.
Carbon is everywhere and understanding the way it moves and is either released or stored by the Earth system is a complex science in itself. Carbon starts its journey downstream when natural acid rain, which contains carbon dioxide from the atmosphere, melts minerals in rocks. This helps transform carbon dioxide to bicarbonate (碳酸氢盐) in the water that then flows in our rivers. This is a very long process, which is one of the main ways carbon dioxide is removed from the atmosphere. Carbon is transported by rivers to oceans and once that carbon reaches the ocean, it is stored naturally in deep sea sediments (沉淀物) for millions of years.
As carbon travels down a river, different processes may impact whether it continues to flow downstream or whether it is released into the atmosphere. For example, human engineering, like extensive dam construction, will result in dramatic changes to how water and sediments travel down the river. Some carbon that fails to reach the sea may return to the atmosphere in some way, which causes more warming.
Earth’s climate is closely related to the carbon cycle. We all know about the essential role of plants in consuming carbon dioxide, but do we know enough about rivers? Changing the chemistry and the course of rivers may have significant impacts on how they transport carbon. Remember: wherever we live, we all live downstream.
1.Where is the carbon in rivers originally from?
A.The atmosphere. B.The rocks.
C.The acid rain. D.The upstream areas.
2.Why is human engineering mentioned in Paragraph 3?
A.To show how important to life carbon is.
B.To explain how necessary it is to build dams.
C.To show how a natural process is interrupted.
D.To explain how humans fight global warming.
3.What does the author want to convey in the last paragraph?
A.We’d better move upstream to live.
B.We should protect plants along rivers.
C.We’d better seek more help from plants.
D.We should be cautious about river management.
4.What is the best title for the text?
A.What Humans Do with Rivers
B.How Rivers’ Transporting Carbon Counts
C.What the Carbon Cycle Means to Us
D.How Living Downstream Affects the Earth
