"I'm going to learn at least one dish each week. You just need to sit back and watch." I got off the phone with my mom and clicked on the TV-box-shaped icon （图标）of YouTube. We were just having a bet about whether I would ever be able to teach myself to cook without her step-by-step guidance.

Technology has revolutionized the way we learn. That was what I believed then. However, after two weeks of watching those instructional videos, the reality of my barely improved cooking struck me in the face. To be honest, the result didn't come off as too much of a shock. Deep down, I had always known that perfection relies in no small part on endless hours of meaningful practice.

I am not alone in experiencing this type of failure. With an impressive variety of online resources at our fingertips, it is natural that we use them to our advantage and learn new skills through "watching" them.

There's nothing ineffective about this kind of learning in itself. However, a recent study published in Psychological Science shows that if you watch an expert performing a skill unknown to you for too long, it will raise your self-confidence in a way that it arouses （激发）your unrealistic expectations of yourself. The dissonance between your true ability and your false view of it can have a negative influence on your learning outcome. You might become as discouraged as I was. And if your determination isn't strong enough, you might just give up halfway.

If right now you are considering learning something new through watching online videos, be it juggling pins （杂耍），ice-skating, or even Michael Jackson's timeless moonwalk, don't forget to mix it up with the tried-and-true method of practicing and repeating. And most importantly, try not to get caught up in the feel-good act of watching.

1.What do we know about the author?

A.She knew her failure resulted from lacking practice.

B.She was astonished at her failure to be a great cook.

C.She disagreed with her mom on how to cook.

D.She was misled by some so-called experts.

2.What's the author's opinion of online resources?

A.They are of poor quality.

B.They are helpful in a way.

C.They are difficult of access.

D.They have benefited her a lol.

3.What does the word "dissonance" underlined in Paragraph 4 probably mean?

A.Dislike. B.Disbelief

C.Disapproval D.Disagreement.

4.What does the author mainly intend to show readers?

A.Online videos are growing in popularity.

B.Mom is always a good example for us.

C.Watching doesn't make you perfect.

D.Cooking is a useful skill.

If you don’t use it, you lose it. At least, that’s how the old saying goes. It refers to the idea that something which does not get used regularly quickly falls into a state of decline. Muscles, for example, will waste away without use. In order to resist this, people take regular exercise to keep their skills sharp.

Well, what about the brain? As we age, our brains can naturally begin to decline. In some cases, this can lead to certain mental conditions such as dementia (痴呆), which I’m sure you will agree, no one wants. However, all is not lost because these days it’s relatively easy to train your brain. Smart phones and apps have put programmes into our hands that can test, maintain and even improve our memories, mathematical skills and a lot of other mental abilities. With a little practice every day, we can keep our brains nice and sharp, right?

Well, no, actually. According to a report from the Global Council on Brain Health, even though many people thought it was important to play online games, such as puzzles and mind games, which are designed to improve brain health, the evidence of the benefits was “weak to non-existent”.

There are other ways to promote the old grey matter. It recommends seeking out new activities that challenge the way you think and are socially engaging, while leading to a healthy lifestyle. Among their suggestions are practising tai chi, taking photography classes, learning new technologies, gardening, art projects or volunteering.

There’s more good news, too. James Goodwin, chief scientist at Age UK has said that brain decline is not inevitable (不可避免的). As long as the activities are “new to you and require your concentrated attention”, they can provide benefits for brain health. So, hurry up, get out there and try something new. Maybe it’s time to try that hobby you’ve always wanted to do. And as for me? I’m off to learn the piano.

1.From which is the text probably taken?

A.A biology textbook. B.A research paper.

C.A travel brochure. D.A healthy magazine.

2.According to the passage, what can the brain training apps help you?

A.It will improve our brain health. B.It can make us smarter.

C.It does little to sharp our brain. D.It can prevent us from aging.

3.How to maintain brain health according to the author?

A.Using smart phone regularly. B.Trying something new.

C.Playing games online. D.Doing what you are good at.

4.What does the passage mainly tell us?

A.How to spend time meaningfully at an old age.

B.How to keep brain sharp.

C.Disadvantages of using smart phones.

D.Advantages of trying something new.

You’ve heard it repeatedly: Make sure you drink at least eight glasses of water per day. The key words are "at least", because, unless you are a child, you need more water than that. The rule is, for every 50 pounds of body weight you carry, drink one quart of bottled or filtered (过滤的) water per day. The average person weighs 150 pounds, so they should drink three quarts per day. A 200 pounds person should drink a full gallon per day. Athletes should drink even more than that. Follow these and you’ve adopted one of the most important health habits.

Our bodies are mostly water, and water is essential to our every function. Drink the appropriate amount, and everything is much more likely to function at the best levels. If you don’t drink enough water, over the short term you will experience tiredness, dry skin, headaches and constipation (便秘); over the longer term, every body function will degrade more quickly. It really is as simple as that.

Things get a bit more complicated in what type of water to drink. Bottled water and filtered water are both good options. Do not drink tap water or distilled water (蒸馏水).Bottled water should be bottled in clear glass containers, not the plastic containers that transfer far too many chemicals into the water. Filtered water can be obtained through low-cost filters.

Tap water should be avoided because it contains chlorine (氯) and may contain fluoride (氟化物), which is poisonous and can have terrible consequences for the body. Distilled water should also be avoided because it can burn up your body of necessary minerals. It has been tied to hair loss, which is often associated with certain mineral lack.

Finally, drink water at room temperature if possible, as ice-cold water can harm your stomach.

1.What’s the meaning of the underlined word “degrade”?

A. Improve.　　　　　　 　　 B. Reduce.

C.　 Strengthen　　　　　　　　 D. Recover.

2.What kinds of water are proper for drinking?

A. Tap water and bottled water.

B. Tap water and distilled water.

C. Bottled water and filtered water.

D. Distilled water and filtered water.

3.What’s the main reason that distilled water isn’t recommended to drink?

A. It leads the body to lack certain minerals.

B. It isn’t clean enough to drink.

C. It contains too many chemicals.

D. It contains fluoride.

4.Which of the following statements is NOT true according to the passage?

A. It is harmful to drink plenty of icy water.

B. One may feel tired due to lack of water for a short time.

C. The water with chlorine is not suitable to drink.

D. The water in plastic containers is safe to drink.

The behaviour of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放)by 80 percent by 2050, part of which will be achieved by all new homes being zero carbon by 2016. But this report shows that sustainable building design on its own—though extremely important—is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.

“Technology is going to assist but it is not going to do everything，”explains Katy Janda, a UKERC senior researcher，“consumption patterns of building users can defeat the most careful design.” In other words，old habits die hard, even in the best designed eco home.

Another part of the problem is information. Households and bill payers don't have the knowledge they need to change their energy use habits. Without specific information，it's hard to estimate the costs and benefits of making different choices. Feedback (反馈) facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension (方面)，suggesting that individuals' behaviour in the home can be personal and cannot be predicted—whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.

Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

1.As to energy use, the new research from UKERC stresses the importance of ________.

A. zero carbon homes

B. the behaviour of building users

C. sustainable building design

D. the reduction of carbon emissions

2.The underlined word “which” in Paragraph 2 refers to“________”．

A. the ways 　　 B. their homes

C. developments　 D. existing efforts

3.What are Katy Janda's words mainly about?

A. The importance of changing building users' habits.

B. The necessity of making a careful building design.

C. The variety of consumption patterns of building users.

D. The role of technology in improving energy efficiency.

4.The information gap in energy use________.

A. can be bridged by feedback facilities

B. affects the study on energy monitors

C. brings about problems for smart meters

D. will be caused by building users' old habits
