1．A Many people miss out on learning opportunities because they let their feelings get in the way.They refuse （1） （learn） or ignore what is said because of who the speaker is.It is true that we cannot help （2） （dislike） some people.But do not forget you can still learn from them.Active learners do not judge people （3） （base） on first impressions or personal feelings.Instead，they separate the message from the messenger.

C Most gardeners will probably say gardening （7） （be） good for you.According to a study，people who garden have a （8） （healthy） diet，get more exercise，and feel less stress.Researchers studied the benefits of gardening in shared community gardens （9） people work together.They suggest gardening may reduce stress because it exposes people to nature，while community gardens also provide （10） （chance） for social interaction.Therefore，they hope the results will encourage doctors and government leaders to regard community gardens as a vital part of the public health system.

2．    Soda and sports drinks are the largest single source of added sugars for Americans.They add an average of 145 calories a day to our diets.Most efforts to reduce drinking focus on soda.That is not enough.Juice is as bad.
    Americans drink a lot of juice.The average adult drinks 6.6 gallons per year.More than half of preschool-age children drink juice every day.These children drink about 10 ounces every day.That is more than twice the amount that is good for them.Fruit juice contains some nutrients（營(yíng)養(yǎng)物）.But it has tons of sugar.One 12-ounce glass of orange juice contains ten teaspoons of sugar.That is about what is in a can of Coke.
    The government is not right when it says up to half of daily fruit servings can be served in the form of 100 percent juice.One-hundred-percent fruit juice is not a natural source of vitamins and calcium.The government also recommends drinking fortified（增加營(yíng)養(yǎng)的）orange juice.This is to get vitamin D.Some brands of juice are even marketed to babies.So what parents should do is read the label and be more careful.
    Government food programs for kids are also at fault.Children in these programs drink more fruit juice than they should.
    Drinking fruit juice is not the same as eating the whole fruit.Fruits like apples and grapes reduce the risk of diabetes（糖尿病）.Drinking fruit juice is the opposite.Juice has more concentrated sugar and calories.It also has less fiber.Juice is easy to drink.It is harder to eat the whole fruit.
    No expert says that juice improves health.It is like other sugary drinks.You can drink it one once in a while.But it is not because your body needs it.Parents should serve their kids water.They should serve the whole fruit.Schools and day care centers should stop serving juice.Government guidelines should not say that fruit juice is like the whole fruit.

3．    Many college students turn to ADHD（注意缺陷障礙）medicine during the exam week，which is regarded as "smart drugs" that will help their academic（學(xué)術(shù)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 will 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（一段時(shí)間）in the lab.The students took the standard 30 mg 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.
