任务型阅读

    Every student is eager to achieve the goals they have set earlier. Here is what experts advise on how to do it.

    ____When it comes to choosing your goal, make sure that it states exactly what it is that you want to achieve. If your goal seems too big, divide it into simpler, easier tasks.

    Write down your goal. You can write it in a journal or write it on a sticky note. Writing keeps your memory fresh and helps you clear up the clutter (杂乱) in your brain. Try to keep a journal or a diary.

    Break your goal down. By chopping your goal up into manageable sections, it allows you to mentally make your way through the goal until the end of a year.____Therefore, you're far less likely to give up or dodge (逃避) your goal by taking shortcuts or refusing to do anything.

    Put a brake (阻力) on distractions. Turn off all distractions like TV, the Internet, your phone and every other gadget you have at home.____

    Make it happen.____ Thinking is a useful start but thinking doesn't do the heavy work and thinking certainly won't move mountains. Go out every morning knowing what you need to do and then do it!

    Stay positive. Keep saying that you can do it. Stay motivated and be confident.

    Reward yourself.____ Every once in a while, if you complete a goal, treat yourself than extra bar of chocolate or make time to read that book you've been wanting to read since two months ago.

A. Don't think to yourself that over time you will manage to do it

B. Choose a specific, realistic and important goal

C. It is necessary to choose a proper way to finish the goals

D. Carry out your goal as soon as possible

E. Don't be too hard on yourself
