【題目】Exercise is a way of keeping the body healthy through being active. Another name for exercise is physical fitness. Most people exercise in their spare time. Sports are some of the most popular ways to get exercise.

The two main kinds of exercise are aerobic exercise(有氧運(yùn)動(dòng))and anaerobic exercise (無氧運(yùn)動(dòng)).Sports such as football and basketball are great forms of exercise 【1】

Exercise affects every part of the body in positive ways. It improves balance and coordination (協(xié)調(diào)). 【4】Exercise strengthens the heart and increases the lungs′ ability to take in oxygen. Through exercise the bones and muscles get stronger, and the whole body becomes healthy and strong.

【題目】Time for a Brainstorm

A brainstorm is a session where a small group of people come together to solve a problem. People voice spontaneous ideas, sometimes just shouting, and a note-taker writes them all down.【1】By getting different ideas out there, ideas are said to bounce off each other and even can help solve the problem at hand. Brainstorming is often a group exercise but individuals can also conduct personal brainstorms.

【2】He defined it as using the brain to storm a creative problem and do so in commando (突擊隊(duì)）fashion, with each stormer attacking the same objective. According to him,, it was easier to tone down a wild idea than think up a new one. He placed importance on the collection of as many ideas as possible and dismissed scientific thinking.

Brainstorming has become one of the most popular ways to solve problems and hold discussion in schools and businesses. Many students brainstorm for a group assignment or even for a personal essay. Sarah Grace, 24, is an Australian marketing analyst and uses brainstorming during all her creative duties. She thinks brainstorming is the best way to work as a team. The sessions get everyone on the same page, everyone moving together and with a clear understanding about the foundations of an event or idea.【3】.

However, a big problem with brainstorming is creating a mess that leads people further away from a solution. 【4】If you don’t have a strong moderator or leader of the brainstorm, can go really off track, and people just start discussing something totally different. Brainstorming can sometimes confuse the human brain.【5】If you brainstorm too much and your page is filled up with all the messy links, you can paint yourself into a bit of comer and get trapped with ideas.

You need to move past brainstorming as soon as you have something workable.

A. The ideas can be smart, strange or crazy.

B. It is caused by a lack of direction from a leader.

C. Brainstorming really helps her organize her thoughts.

D. Brainstorming really is the best way to build team spirit.

E. It can open too many doors and not suggest a clear direction.

F. Brainstorms were popularized in the 1940s by American advertising boss Alex Osborn.

G. They can be words; phrases, paragraphs and anything that can help answer the question.

【題目】Every person wants to achieve the goals set at the beginning of a new school year. The following are some ways to help you achieve your goals.

●【1】When it comes to choosing your goal, ensure that it states precisely what it is that you want to achieve. Don’t generalize. Your goal should involve both what you want to achieve and the effort that you will put in to achieve it.

●【2】Having a copy of your goal makes it real. You can write you goal in a journal you’ll be keeping all year, or you can write it on a poster and stick it on your desk so that you can look at it each day. Every time you remind yourself of your goal, you’re training your brain to accept the effort needed to make the goal happen.

●Try various methods. One may not work while another may be just right for you. 【3】Some people learn best through writing, some through listening and reading, and some through talking it through. Once you realize which way works for you, you can work better and achieve your goal easily.

●Think positive. 【4】Negative thoughts are unhelpful and they became roadblocks. Stop telling yourself you can’t and start telling yourself you can, and talk about you are doing rather than hoping you can do something. Always believe that you’re capable, even if you have difficulty along the way.

●Reward yourself along the way. 【5】Occasionally, when you’ve achieved certain “milestones” in your goal plan, take a break and reward yourself. Watch a movie, visit a friend who lives across town, go to the ice cream shop with your friends or buy yourself something new.

A. Write down your goal.

B. Choose specific and realistic gals

C. Be aware of the way you learn best

D. Remember that everyone makes mistakes

E. Set aside some time each week for exercise

F. All study and no reward can break your spirit

G. If you’re not in the right state of mind, you won’t be able to succeed.

【題目】There are many benefits of singing in a choir. They range 【1】the social: having the opportunity 【2】(make)new friends, to the physical benefits of learning to breathe 【3】(proper). Research has also shown that young people 【4】sing in choirs do better in their studies and have【5】tendency to be healthier.

But the first question you should ask【6】(you)if you are considering joining a choir is “can you sing in tune?” It might seem obvious, but 【7】you can, there is little point in seeking out a choir because you’ll only get rejected. Every choir you apply to join is going to audition(面試)you. Don’t worry if you can’t read music; that can be taught later. If you 【8】(accept), you’ll find choir practice to be hard work, but great fun, because they’re social events as much as music training. You will learn to read music and how to sing with confidence. Your voice and technique will develop, probably quite quickly with proper 【9】(instruct), and you may just end up【10】(wonder)why you didn’t do this years ago.

You may have grown up living with sisters and brothers, or this may be your first time sharing your living space with someone else. 【1】However, it can also be a great part of your college experience. Follow these tips to make sure you and your roommate keep things pleasant and supportive throughout the year.

Be clear from the beginning.

Maybe you hate it when someone interrupts you when you are sleeping every morning. Maybe you need ten minutes to yourself before talking to anyone after you wake up. ___【2】 It's not fair to expect him or her to pick up on them right away, and communicating what you need is one of the best ways to get rid of problems before they become problems.

____【3】

This may seem simple, but it's probably one of the biggest reasons why roommates experience conflicts. Don't you think he'll mind if you borrow his shoes for a quick soccer game? For all you know, you just stepped over the line. Don't borrow, use, or take anything without getting permission first.

Be open to change

You should expect to learn and grow and change during your time at school. _【4】As the term progresses, realize things will change for both of you. Be comfortable setting things that unexpectedly come up, setting new rules, and being flexible to your changing environment.

Follow the golden rule.

__【5】 No matter what your relationship is at the end of the year, you can take comfort knowing you acted like an adult and treated your roommate with respect.

A．Respect your roommate's things

B．Let your roommate know about your preferences

C．Treat your roommate like you'd like to be treated

D．Living with a roommate is really a wonderful thing

E．Having a roommate surely has its challenges

F．You should correct your bad habits first
