Books which give instructions on how to do things are very popular in the United States today. Thousands of these "How to" books are available; in fact, there are about four thousand books with titles that begin with the words "How to". One book may tell you how to earn more money, another may tell you how to save or spend it, and another may explain how to give your money away.

Many "How to" books give advice on careers (职业). They tell you how to choose a career and how to succeed at it. If you fail, however, you can buy a book called “How to Turn Failure into Success”. If you would like to become very rich, you can buy the book “How to Make a Million”. If you never make any money at all, you may need a book called “How to Live on Nothing”. One of the most popular types of books is one that helps you with personal problems. If you want to have a better love of life, you can read “How to Succeed at Love Every Minute of Your Life”. If you are tired of books on happiness, you may prefer a book called “How to Make Yourself Miserable”.

Many of these books help people use their time better. Some people want books which will give them useful information about sports, hobbies, and travel. Other people use their free time to make repairs and improvements on their homes. They prefer books which give step by step instruction on how to repair things like plumbing (卫生管道工程) and electrical wiring, or on how to redecorate (重新装饰) or enlarge a house.

Why have "How to" books become so popular? Probably because life has become so complex(复杂的). Today people have far more free time to use, more choices to make, and more problems to solve. "How to" books help people deal with modern life.

Study hard. Get plenty of sleep. Eat a good breakfast. Each of these things can help students do their best on exams. Now scientists say another thing might also influence students’ test scores. Students in stuffier (通风不畅的) classrooms did worse on tests than students in buildings with fresher air, new research (研究) found.

Opening windows can help provide fresh air. Some buildings also use fans to bring in outdoor air. Each time someone breathes, he or she breathes out CO2. When rooms are stuffy, the level of CO2 in those rooms can build up. A 2012 study showed that college students had more difficulty giving all their attention to their learning when indoor CO2 levels were high. And other research has found that primary school students in stuffier classrooms stayed homesick (想家的) more often. In a different study, researchers examined the air quality (质量) in 100 fifth-grade classrooms. They found that in most classrooms, the air quality did not meet the standards (标准).

These same research groups now find that better air is connected with better test scores too. As part of the research, Richard Shaughnessy measured CO2 levels inside and out of 140 fifth-grade classrooms at 70 schools. The CO2 levels helped them know how much fresh air was running through each classroom. The quality of indoor air in each classroom was then compared to its students, scores on a Maths test. Overall, the average score for this test was 2,286 points. But kids in classrooms with the best air quality scored about 144 points higher than students breathing the stuffiest indoor air. The study shows that air quality and test scores are really connected, but the influence is small.
