You slowly open your eyes. Ah, another beautiful morning. You think to yourself, "It's great not to have anything to worry about". OH NO! Today is exam day and you haven’t studied enough! 【小题1】  How can you deal with the mountains of stress that exams seem to create? Read on to find out some useful study tips to prepare for exams:
Get into a routine
If you get started early enough before your exams, you will find you don’t need to put in any all-nighters. Find the time of the day that you study the best. Pick a couple of hours and stick to this study time. Get to know how you learn the best.  【小题2】  
Plan ahead
Planning ahead is the best way to maximize your chances of good grades. You may have only limited time to study.   【小题3】  Ask your teachers to help you make a list of the most important topics to study. If you stick to a schedule, it will start to seem manageable.
Look after yourself
Fresh fruit and vegetables will give you reserves of energy and increase your ability to concentrate. Don't stay awake all night trying to study. Wind down after study and try some relaxation exercises. Having regular exercise will keep your mind active.   【小题4】 
Assistance and resources
Your teachers will usually be more than happy to meet with you outside of class times. Make appointments to meet with them regularly. Don't waste their time, however. Plan what you want to discuss and have some questions written down.   【小题5】  Practise on past exam papers, but don't rely only on them. There is no such thing as a short cut when it comes to exams. 

When I was growing up in the suburbs of New York, our first local Earth Day was organized around a drive to a town field where families were urged to empty items from their basements （地下室）for recycling rather than dropping them in the dustbin. It was an eye opening idea for a kid in 1970.

But as an environmental reporter, I'm bored of the large amount of deals and promotions that arrive by email or in my office or home mailbox on Earth Day. Like Valentine's Day, Earth Day has become a huge marketing opportunity—a way to promote consumption.

In fact, Earth Day is such a good sales opportunity that some shops, like Target, have expanded Earth Day into Earth Month.

There isn't time to give you a variety of the Earth Day shopping opportunities I was informed of this past week. They included deals on buying bottled water and earth-friendly wipes.

My award for the silliest promotion: a plan to gift 25 of the most environmentally conscious stars with unique, useful and “green” products and services, including skin care products, cheese-

cake and artwork. My guess is most of the stuff will end up in celebrities' garbage.

Is buying and selling a good way to celebrate and protect the environment? I would argue that Earth Day might be an occasion to consider giving up purchases or habits that are environmentally questionable or that we could happily do without. How about not buying bottled water, but refilling a water bottle? How about not buying foods—even “organic” foods—that are packed in non-recyclable plastic?

Don't get me wrong. The company of Bridgestone is celebrating Earth Day by promising to repurpose a spent tire（利用废旧轮胎）for every tire that it sells. Verizon will plant a tree for each cell phone you trade in. Some coffee stores will even refill reusable cups at no charge. Target is giving out free reusable carrier bags without requiring a purchase.

But few shopkeepers are taking the next step－charging a fee at the cash register for disposable plastic bags, a common practice in Europe－to encourage customers to use those new reusable carriers.

Earth Day is transient（短暂的）. If you only showed love on Valentine's Day, would that really mean anything at all?
