Many college students turn to ADHD(注意缺陷障碍) medicine during exam week, which is regarded as “smart drugs” that will help their academic(学术的) performance. The thinking is that if the drugs help students with ADHD improve their focus, they should provide the same benefit for people who don’t have the disorder.
But a new study shows that drugs can actually damage brain function of healthy students who take the drug hoping to boost their intelligence. “It’s not a smart drug which suddenly improve their ability to understand information they read,” said Lisa Weyandt, a professor at the University of Rhode Island.
To test whether this effect is real or not, researchers organized 13 students to take part in two five-hour study sessions(一段时间) in the lab. The students took the standard 30mg ADHD drugs before one session, and a sugar pill before the other. Students on ADHD drugs did experience an increase in their blood pressure and heart rates. “The medicine was having an effect on their brain,” Weyandt said. The students also showed an improvement in their ability to focus, the researchers found.
However, students on ADHD drugs experienced no improvement in reading comprehension, reading fluency or knowledge reviews, compared to when they’d taken a sugar pill. “We read aloud stories to them and asked them to recall information from the stories,” she said. “That didn’t improve.”
Worse, the ADHD drug actually harms students’ memory. It’s often misused because people pull all-nighters and they’re tired, and they think it’s going to keep them awake. Maybe it does, but it’s certainly not going to help their academic work. The brain is still developing until the mid to late 20s. It’s important to keep it healthy. There’s also a chance that ADHD drugs could endanger a student’s heart health.

Many high school students consider a college education useless. Therefore, they choose not to go to college. If you’re one of them, think again. Here are some reasons why you should go to college and receive a good education there.
Schools and universities are the first sources of knowledge. We take that knowledge later on to build our careers after graduation. More knowledge will be gained after you start working, but without an education, that job will not be within easy reach. Knowledge leads to knowledge.
While limited within the walls of the educational institutions, we openly explore other cultures of the world. We come to know that ours is not the only culture. Other cultures have valuable insights to share, enriching our own. Education also makes us want to travel and interact with various cultures, broadening our horizons.
When there’s a downturn (衰退) in the economy, those who attended college will be more likely to find a new job than those who only finished grade school and have a limited skills set. The more education you have, the more chances you will get to improve the quality of your life as you have a better job and earn a higher salary.
When you’re skillful and knowledgeable, you get to “rub knees” with people of similar backgrounds and tastes. It means a good education leads to excellent networking. Good networking can benefit you a lot in your later life.
A good education makes you a more interesting person. You can talk about ideas and events instead of just other people and what’s on sale in stores. An educated person doesn’t gossip, having a preference to discuss ideas and listen to what other people have to say.
1.Paragraph 2 mainly shows that going to college allows you to ______.
A. have a chance to study abroad B. keep gaining knowledge
C. become a more interesting person D. realize the importance of knowledge
2.According to Paragraph 3, what is the advantage of going to college mean?
A. Having a greater understanding of different cultures.
B. Being limited within the walls of a college.
C. Valuing our own culture much more.
D. Thinking differently from others.
3.By giving the example of a downturn in the economy, what does the author want to show?
A. A good education can improve your tastes.
B. A good education sometimes means nothing.
C. A good education means you will not lose your job.
D. A good education allows you to keep a life of high quality.
4.What is the text mainly about?
A. Sources of knowledge.
B. Benefits of attending college.
C. The disadvantages of not being educated.
D. The reason why some people think college useless.

Have an open mind. Especially if you are going to a bigger school, it’s important to have an open mind. 2. Yet when you get to college, there are people from all over that have different views on things and act in a different way.
