When you get up in the morning, do you find it hard to choose what clothes to wear If so, you probably need help to make the bigger choices(选择)in your life, like what to do when you’re older.
Brave New Girls, by American author Jean Gadeberg, will help you make such choices. To make them, it says you must be a brave new girl. A brave new girl is one who is confident, healthy and happy. A brave new girl can realize her dreams.
To be brave, you need to make decisions (决定)for yourself. Other people may tell you what to do, but you should not listen to them. You must only do what you want. If you always wear clothes like your favourite TV star, for example, you must stop doing so. Instead, you should become your own star and wear the clothes you want.
The book also tells girls to start liking how they look. You have to like your body, it says. If you don’t, you will not take good care of it and won’t stay healthy.
The book also says that girls must start becoming more confident. If you are confident, you’ll succeed(成功)in life. A good way to become confident is to realize that you are as clever as boys. In fact you are. Just look at their grades! Today’s brave new girls will become tomorrow’s brave new women. Only they can realize their dreams and become who they want to be.

Check your skills and personality.
Certain hobbies require certain skill sets.

You may study differently from your friends, but your study habits are not wrong!
Kelly and Maria are best friends with a lot in common. They love doing things together, such as going to movies and concerts, shopping, or just sitting at a small cafe. Since they take a lot of the same school subjects, they would love to study together, but they find this impossible. Their working styles are so completely different that they can’t be in the same room while they are studying.
Kelly would like to study in a clean, open space, while Maria works best with books, papers and other things around her. Kelly prefers to study in a totally silent room, but Maria loves to play music or even have the TV on. Kelly can sit for hours without moving, and often gets all her homework done in one sitting. Maria, however, is always getting up, and says that she thinks best when she’s on the move.
You might be asking yourself: which way of studying gets better results Many people believe that a silent, tidy setting(环境)is the way to go, ________. Some research has even shown that outside noise and untidiness help some people focus(聚 焦)their attention, because it makes them form a “wall” in their mind around what they are doing and improves their focus.
So, if you’re a student who chooses to study while sitting at a table in a busy shopping center, don’t worry about it. If you work in total silence, that’s OK, too. Judging from Kelly’s and Maria’s study habits, the best way to study is the way that works for you. In their very different ways, both of them do well in school, and both finish their work within the required time as well.
37. Kelly and Maria are mentioned as an example in this passage to ____.
A. discuss two different study habits
B. compare the differences in their hobbies
C. show the importance of a good study habit
D. express the writer’s worry about their friendship
38. Which of the following is the best to fill in the blank in Paragraph 4
A. and they have difficulty in study
B. and it can be true for most of them
C. but that doesn’t seem necessarily true
D. but nobody does research on this question
39. What can we infer from the last paragraph of this passage
A. Students who like to study in silence will be more successful.
B. Both study habits can help students make progress in their studies.
C. Only a small number of students can study well in a noisy situation.
D. Friends with different study habits can do better by studying together.
40. What can be the best title for the passage
A. Are you studying the “right” way
B. How can you improve your study habits
C. Is it possible for friends to study well together
D. What are the advantages of different study settings
D(原创)
“Just do it” seems to be the most common “recipe(秘诀) for success” that we share with everyone. But when it is advised to us, it turns out that it does not work. But the good news is that there are more realistic(现实的) ways on how to make your dreams come true.
Almost each student has his or her own dream. Everyone’s dream is not always the same. And his or her dream can be big or small, such as getting the first prize in the sports meeting.
How do you usually deal with your dream as soon as you have a dream Do you ever try to make your dream come true
A famous writer named Andrew Matthews tells us that making your dreams come true is the life’s biggest challenge. You may think you’re not very good at some school subjects, or that it’s impossible for you to become a writer. Those kinds of ideas stop you from realizing your dream.
In fact, everyone has the ability to achieve his or her dream. The first thing you must do is remember what your dream is. Don’t let it leave your heart. Keep telling yourself what you want every day and then your dream will come true faster. You should know that a big dream is, in fact, made up of many small dreams.
Never give up your dream. There will be difficulties on the way to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will help you to get better exam results, and saving five yuan instead of buying an ice cream means you can buy a new book.
As you get closer to your dream, it may change a little. This is good as you have the chance to learn something more useful and find new hobbies.
Use these recommendations on how to make your dreams come true and never give up until you reach the result.
41. Almost everyone’s dream is ____ according to the passage.
A. same B. different C. easy D. strange
42. Where does the biggest difficulty on the way to your dreams come from
A. Yourself. B. Your friend. C. Your school. D. Your parents.
43. Everyone has the ability to achieve ____ according to the passage.
A. customs B. hobbies C. dreams D. habits
44. If you don’t remember what your dream is, you may make your dream come true ____.
A. faster B. more slowly C. more easily D. more possibly
45. What’s the best title of this passage
A. How to live happily B. How to achieve dreams
C. How to make friends D. How to study well
