Detectives often look for footprints when they try to solve crimes. Scientists use footprints, too—dinosaur footprints when they try to figure out how dinosaurs lived and moved.
Dinosaurs died out about 65 million years ago. Today scientists work to solve the mysteries of these ancient animals.
Footprints, or tracks(脚印), are an important way to learn about dinosaurs. Christian Meyer of the Natural History Museum in Basel, Switzerland, calls dinosaur tracks “the closest thing to a movie” of dinosaurs.
“They tell us something about the size of the animal, the way they were walking…they tell us something about their speed,” Meyer said.
Tracks also show that dinosaurs sometimes traveled in groups. Traveling in groups probably helped dinosaurs protect themselves from enemies. Plus, some meat-eating dinosaurs may have hunted in groups, much like wolves do today. Bein
g in a group could help dinosaurs work together to kill large animals.
Dinosaur footprints can be as small as a few inches across, but they can also be as big as a few feet across. Dinosaur footprints have been found throughout the world at ove
r 1,500 sites, including a T. Rex footprint in New Mexico. “Trackways” are groups of footprints.
And scientists aren’t the only ones finding dinosaur tracks—kids can, too! Eleven-year-old Mark Turner and nine-year-old Daniel Helm discovered dinosaur tracks in British Columbia, anada. Soon scientists began studying the tracks.
Scientists and other people interested in studying dinosaurs are working to save the trackways from activities like construction and mining.The passage mainly tells us that_______.

Despite the fact that it has never been seen almost everyone is familiar with the legendary unicorn(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.
According to the legend, anyone attempting to catch a unicorn had to be extremely careful as it was very fierce and dangerous. A clever trick suggested by unicorn-trappers, in order to catch this amazing animal without being hurt by its horn, was for the hunter to stand in front of a tree and then to move quickly behind it as the unicorn dashed angrily. Hopefully, the creature could then be caught when its horn was stuck in the tree.
When hollowed out and used as a drinking-cup, the unicorn’s horn was said to have the power to offer protection against person. It was believed that nobody could be harmed-by drinking the contents of a unicorn’s horn. Right up until the French Revolution in 1789, the French court was said to have used cups made of “unicorn” horn in order to protect the king. In addition, the horn was said to have medicinal value, so much so that it could be sold for more than ten times the price of the same weight of gold. What, then, was “unicorn” horn? We know at times the rhino(犀牛) was confused with this legendary creature.

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.
Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.We can infer from the first paragraph that ________.
| A．learning better at school shows power in your job |
| B．the better you are at school subjects, the more helpful they are in your career. |
| C．learning each subject well is an ability in many jobs. |
| D．we should think about how to find our career |

Lots of kids go through times when they’d like to change their hair. Often, it’s girls who are most concerned(关心的), but boys may be interested in how their hair looks, too. Sometimes hair will change as you get older----all by itself----when you go through puberty(青春期).
Maybe it used to be lighter and now it’s darker. Or maybe it’s oilier than it used to be, and now you need to wash it more. It’s also normal, as you’re getting older, to notice your appearance more often. You might suddenly decide you want a hairstyle like other kids at school have. But some styles and looks require chemical treatments and long hours in the chair at the hair salon. Some people dye(染)their hair a different color, get a bunch of braids(辫子），or make their hair straight when it’s curly（卷曲). Are these treatments OK for kids? That’s something you should discuss with your parents. At any age, any chemical or heat applied to(应用于) the hair can damage the hair or cause it to break off.
Any styling that pulls hard on the hair can also hurt the scalp(头皮) or cause hair loss. Styling tools, such as curling irons and straightening irons, get very hot and can cause burns. And chemicals used to color, curl, or straighten hair can be very harmful if they get into your eyes or onto your skin.The word “kid”in this passage refers to ____________.
| A．girls | B．boys | C．students | D．not only girls but also boys |

| A．Change the hair style to act in a play. |
| B．It changes naturally with the age. |
| C．You want to make yourself look beautiful or cool. |
| D．A boy’s hair may become darker and darker when he gets older. |

| A．If you want to change the color of your hair, you have to use chemical. |
| B．Hair can be straightened with an instrument. |
| C．You’d better change your hair with the help of your parents. |
| D．Hair change by chemicals or instruments can harm the hair or the scalp。 |
When my daughter was in the fifth grade, she came home from school almost every night with three or more hours of homework. It was my duty to help her get it done. One night she worked until midnight doing her homework.
I felt annoyed, but I didn’t want the teacher to think I was lazy. So I never complained. I wasn’t sure, but it seemed to me that five hours of homework was a bit too much for a fifth grade student.
Later, I found out that parents and educators have discussed about homework for more than a century. Parents who like more homework want to give their children every advantage to succeed in today’s world. Some educators see homework as a way to help students perform better in tests.
Other parents dislike the recent trend toward more homework. They don’t want to stay up until midnight helping their children. They would prefer to spend their time going to the park or reading some really good books with their children. Added to the opposition(反对)are those who say that homework increases the gap(差距)between the rich and the poor. That’s because middle class families do better when it comes to helping their children with their homework.
So, who is right? Is homework an enemy or a help? According to experts, the truth lies somewhere in the middle.The author thought that her daughter’s homework _________.
| A．was too difficult |
| B．was too much to finish |
| C．was done more carefully than other students’ |
| D．could be done as long as she helped her daughter |
The author never complained to the teacher because _________.
| A．she was too angry to talk with the teacher. |
| B．she did not like complaining. |
| C．she was afraid of being thought lazy by the teacher. |
| D．her daughter would be annoyed if she complained. |
In the last paragraph, experts __________.
| A．think middle school students should do lots of homework. |
| B．haven’t come up with any idea to solve this problem. |
| C．think homework should be given, but not too much. |
| D．support the idea that homework is good for students. |
