    【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Being successful in an exam is not just about studying hard and knowing the subject inside out. 1

    Research has shown that the calmer the mind, the better its ability to register and remember information. 2 When the mind is relaxed, it is in the "state of alpha", where your brain waves are at about seven to fourteen cycles per second, the most helpful state for studying.

    Choose a quiet place for studying and have everything handy that you need: books, pens, something to drink. 3 In this case, you can see yourself being congratulated by your family, friends and teachers. Enjoy the experience. And now you should be completely charged up and ready to absorb and keep important information.

    4 It is a good idea to make a list of all the important things you have to learn, in order of importance, and estimate how much time you need for each one. Add it all up and compare this with how much time you have available. This will tell you if you have time to read slowly and carefully, or if you can only skim; also it will show you how many times you can afford to look over the same information.

    Because stress can have a negative effect on your memory, it’s important to stay calm during tests. 5 Breathing exercises during the examination, for example, can be extremely effective in helping you relax and reverse your stress response: just take deep breaths, and let the stress coe out when you exhale(呼气).

    A. Learn to both read between lines and skim.

    B. Ensure that you sleep and eat well before a test.

    C. Relax your body and mind and imagine the day of the results.

    D. There are some stress relief techniques that can help to calm you down.

    E. There are other things that you can do to help ensure you get good grades.

    F. Every time you sit down to study, give yourself five minutes to calm your mind.

    G. Depending on what you want to study, and how much you have to cover, plan your time.

    How to Use Social Media Positively

    Nowadays so common is Social media in our society that almost everyone is connected to some form of it, whether it is Twitter, Facebook or even Pinterest. We are in a fast-paced, technologically evolving society and we are addicted to social media. 1

    So how does one ensure a positive online reputation? It’s simple:

    Keep it clean. Party photos with alcohol are an absolute no-no. Would you want to have your boss see these photos? 2 Make sure to post contents that you feel positively reflect you, your creativity and your skills.

    3 You have a private Twitter account so you can post anything you want? This is decidedly not the case. Privacy settings make it harder to see your full account, but it’s not impossible. Under no circumstance should you rely on privacy settings as a way to protect inappropriate contents.

    Ensure you’re careful and professional. Keep it classy (优等的)! Discover your brand, or what you want people to think of you. Proper spelling and grammar is always a plus, but it may not be your brand. 4 In this way, you can earn approval.

    Follow these simple rules and you’re on your way to building, or restoring an online reputation. Using social media positively doesn’t mean you can’t have fun and use it to express yourself; however, you want to ensure that you’re OK with anyone seeing everything you post. 5 So your post can get your friends active and happy.

    Like it or not, your social networks reflect you ── make sure you look like the shining star that you truly are.

    A. Try to do everything as well as you can.

    B. In fact, we long for social media and need it.

    C. Social media is very fast to use but very difficult.

    D. Don’t trust privacy settings at all.

    E. Be entirely sure about what you’re posting.

    F. Once you click post, there’s no looking back.

    G. Make sure your post is written personally.
