Will our parents check our homework? Not really. Since having already growing up, we can’t act like little baby and rely on our parents all the time.
When I was in Grade Three, my parents asked us to check my homework by myself. I don’t know what to do in that time, so I cried. Before that, I got used to correcting my own homework and became more independent.
Check homework by ourselves is very good habit. It can not only help us find mistakes in exams more easy but also let our parents worry less about our studies. Because parents will leave us some day, so we should learn to do everything by ourselves.
One day, when I was 12, my mother gave me________: I was to walk to the public library and borrow at least one book for the summer. This was one more weapon for her to________my strange problem-inability to read.
In the library, I sat down on the floor in the children’s section, and________a few books off the shelf at random. The cover of a book caught my eye, it___a picture of a dog. I had recently had a dog, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone,_____to someone who had a space and money to care for him. I never forgot my dog.
There on the book’s cover was a dog which looked___to my dog, as if they were the same one. I ran my fingers over the picture of the dog on the cover. My eyes ran across the________, Amos, the Dog with a Plan.________I had read the title. Without opening the book, I borrowed it from the library.
Under the_____of a bush I started to read about Amos. I read very slowly with difficulty. Though________were turned slowly, I got the main idea of the story about a dog who, like mine, had been________from his family and who finally found his way back home. At the end of the story, my mind________the final scene of reunion, on and on,________my own lost dog and I were, in my mind, running together.
My mother’s_____returned me to the real world. It___to me that I had read a book, and I had loved reading that book. Books________be incredibly wonderful and I was going to read them.
I________told my mother about my “miraculous” experience that summer, but she saw a slow but remarkable improvement in my classroom____during the next year. And years later, she was______that her son had read thousands of books, was awarded a PhD in literature, and____his own books, articles, poetry and fiction. The power of the words has held.

Most young adults prefer to have a separate or independent life from their parents or families as soon as possible. This is because they have strong urge for freedom in doing what they desire.1.. This should not be surprising since often they, actually not ready mentally although they are physically ready. It’s widely understood that to live independently requires a lot of energy and it’s not easy at all. In this twenty first century, people may need more and more preparation because competition is increasing rapidly.2.. Therefore, they will not be able to support and fulfill their necessities.
3., some young adults may need to take more time to prepare themselves before going out to struggle. Taking time to get more education and living with their families for a longer time may lead them to a better independent life because they will be well prepared for the hard life outside. Still living with families for too long will not be good idea because they could get too used to it and tend to be less independent.
4.. He or she must decide whether they’re ready to leave their parents to have an independent life or not. The decision will vary from one person to another. A person should judge that he is capable of fulfilling his needs without being dependent on his parents; this indicates that he is ready for his independent life.5..
A.But in fact many of them fail
B.Conflicts appear between young adults and their parents
C.So living independently at an early age is not suitable for all young adults
D.Otherwise he might need to stay longer with his parents
E.The time to live independently depends on the person himself
F.Enjoying freedom is the first thing young adults take into consideration
G.An observation shows that many University graduated students are unemployed
The beginnings of life provide scientists with some of the most difficult questions on modern science. Our knowledge of the development of cells, from which all forms of life are made, is not complete because we do not understand very well conditions on our planet four billion years ago. Why and how did cells first appear? Was this very likely to happen under the conditions then, or was it due to chance? Might this happen in other places in the universe?
A group of scientists at London University are trying to answer these questions. They started by studying the way in which the first cells on Earth might have been formed. Next they will use powerful new telescope to look at places far away in the universe. The scientists hope that the results will improve our understanding of the development of life on Earth and help us to find life on other planets.
Dr. Nick Lane, who is in charge of the team, has suggested that four billion years ago warm water springs on the floor of the earth ocean might have helped create life. Each spring consists of tiny connected holes that water passes through. The team have created models of these springs in their labs. You have found that they encourage chemical reactions between hydrogen in the liquids that come out of them and the carbon dioxide in the sea water. These chemical reactions can create the “building blocks” of life, these building blocks are not living themselves, but when they are enough of them joined together in the right way, they can make living things. The water in the system of springs move the building blocks around until there are a lot of them in a small area. Things that look very much like real living cells can be made in this way.
These reactions and changes show us how life on earth and on other planets could begin. When sea water goes through tiny holes in the earth’s surface, it gets very hot and causes a chemical reaction with rocks. When this very hot water goes back up and meets cold sea water again, other chemical reactions happen. Lane explains, “The conditions needed for life are rock, water and carbon dioxide. This could be found on millions of exoplanets (planets beyond solar system), so basic life should be everywhere.”

A.Rock, water and carbon dioxide are three things to make life.
B.How different chemicals mix together to produce cells.

B.The new powerful telescope can help us find cells on the other planets.
C.The ingredients for life are basic and should be all over the universe.
D.Chemical reactions can happen everywhere in the universe.
4.What is the best title for the text?

Dolphins make a wide range of communicative sounds and also display something called vocal learning, which is the ability of an animal to modify its vocalization(声音)based on its experience with other animals.
Mainly, there are three types of dolphin vocalizations: whistles, clicks, and burst pulses. People still don’t know their precise meanings, but people do know that dolphins use their vocalizations as a way to communicate with one another.
The dolphin whistles are very high frequency sounds, partially above the range of human hearing. What’s fascinating is that each dolphin has a signature whistle, which is unique to each individual dolphin. It allows them to call to or identify each other.
No two signature whistles are same-sounding. As members of the same family, their signature whistles have similar elements. Dolphins use them as a contact calls. They call to each other while travelling and searching for food. It helps keep the group together and helps mother and children find each other. The uniqueness of each dolphin’s signature whistles is just like the following example: if you were travelling in the forest with one other person who was just out of sight, you would call out, “Are you there?” and the other person would respond. But if there were several people in the forest, you would have to call that person’s name.
In addition to whistles, dolphins produce clicks, which are actually sonar or sound waves. They use clicks to communicate, but more importantly to navigate and hunt. How? The sonar clicks bounce off objects and then the dolphins convert the incoming signals into a three dimensional picture, a mental map of what’s around them. The clicks are extremely sensitive and accurate. The sonar clicks are also very strong. One reason why dolphins swim side by side is to avoid interference from each other’s sonar clicks. Interference would be confusing and it would prevent them from getting an accurate picture of their surroundings. And what’s interesting is dolphins will turn off their sonar when another dolphin passes in front.
The third category of dolphin vocalizations is burst pulses. These are all the other sounds the dolphin makes-squeals, barks, groans and so on. Burst pulses are used to display dislike, claim their living area and attract a mate.

Night after night, mom came to my bed and said good night, even long after my childhood years. As part of her nightly routine she would lean down, push my long hair out of the way and then kiss my forehead.
I can’t remember when it first started annoying me-her hands pushing my hair that way. But it did annoy me anyway for they felt rough against my young skin. Finally, one night, I lashed out at her, “Stop doing that-your hands are too rough!” She didn’t say anything in reply, and never did she end ml y day with that special expression of love again. That night, I found myself lying awake long after she left my room. Regrettably, I never told her I was sorry.
Time after time, with the passing years, my thought would often return to that night. I missed my mother’s hands, and her goodnight kiss upon my forehead, sometimes the memory of that unspeakable night seemed very close and sometimes far away. It was always there in the back of my mind.
Years have passed, I’m no longer a young girl, and mom is in her mid-seventies. Those hands I once thought to he rough are still taking care of me and my family. Over the years, those hands have reached into a medicine cabinet for the remedy that would calm a young girl’s upset stomach or soothe boys painful knee. The very same hands have also cooked the best fried chicken in the world, gotten stains out of my jeans and dished out ice cream on a hot summer day.
Now my own children are all grown and gone, and mom no longer has clad. On special days, I find myself drawn to her house to spend the night with her. On the Eve of one Thanksgiving, as I was about to fall asleep in my old bedroom, a rough, but loving hand, hesitantly stole across my face and brushed the hair from my forehead. Then a kiss, ever so gently, touched my eyebrow.
For the thousandth time I recalled the night when my young voice and gratefully complained, “Stop doing that-your hands are too rough!” then I caught Mom’s hand in mine involuntarily with the deepest regret, I told her how sorry I had felt about that night all those years. To my surprise, Mom didn’t know what I was talking about. She had forgiven and forgotten long ago. That night, I fell asleep with new appreciation for my gentle mother and her caring hands. The guilt that I had felt for so long suddenly disappeared, and nowhere was it to be found.
