Here are five cooking habits that could be costing you important nutrients, causing you to overeat——or even making you sick.

Boiling vegetables

A 2015 review showed that boiling vegetables resulted in a high loss of vitamin C. 1. "If you're not drinking a soup, you're missing out on nutrients," says Nishta Saxena, a dietitian based in Toronto .

Washing chicken

While your favourite old cookbooks likely tell you to wash a chicken before cooking, this outdated advice is a safety risk. Cleaning meat in water may remove some of the bacteria, but it's also likely to pass it around your kitchen. 2. And clean your hands after you've finished the cooking.

Removing skins from fruits and vegetables

"Large amounts of nutrients are found in the skins." says Liz Powell, who is a dietitian from Vancouver. " Concern about chemical remains isn't a good enough reason to do the removing. 3."

Mixing everything

A smoothie (a mixed drink) is a smart way to eat some greens. 4. They're often short of protein and healthy fat. These things work together to keep us feeling full and satisfied. Without them, it's not really a balanced meal, Powell suggests adding some foods which contain protein or having a piece of wholewheat(全麦的)bread on the side.

Overdressing salads

We think we can add anything to salads, and they'll still be a nutritious choice. But it's just not true. If you're topping your bowl with dried strawberries and sweet cheese, you've easily added 30 grams of sugar to your so-called healthy lunch. 5.

A.You should choose healthy produce for your family.

B.But these kinds of drinks are likely to be unbalanced.

C.To stay safe, don't wash the meat when preparing it.

D.Cabbage. for example, loses about 33 % of its vitamin C.

E.Nuts are better choices to improve the taste of your greens.

F.The skins of potatoes contain more nutrients than its inside part.

G.Washing your produce will remove some chemicals from the surface.

Time wasters are real enemies of success. Time wasters could be people, events or habits that lead to the opposite path away from our goals. The most important starting point in removing the time wasters in life is to know about them. We need to sit down and analyze the activities which take our time.

Start by making a list of our activities and sort out the neither urgent nor important ones. Sometimes it could be a simple addiction to a TV Soap Opera, constant distractions, or even one of our core （核心的）activities that we are not excellent at doing. We can, for instance, imagine that we are a business owner and we keep sabotaging our business deals, leading the company into great financial problems. It may be time for us to have our associates do the marketing while we concentrate on the areas we are best in. The next thing would be to make sure that we plan our daily activities. One of the obvious reasons is that we will have an upper hand in fighting against time wasters in our schedule. If what we want to do or what we don’t want to do becomes clear, our focus is strengthened.

Moreover, when we think of people we spend time with, we are sure to notice that some have a more positive impact on our success while others have a negative one. It is important to be able to distinguish them especially with regard to our schedule. While we do not advocate for everyone to throw away relationships, it is good to know that helping a friend who is emotionally disturbed can wait till dinner time. Finally, do the same to our habits. List all the habits and addictions that take any amount of our time. Then, take a little time to straighten them out in line with their importance and urgency.

Depending on our analysis, kill those that are harmful to our goals in life.

1.Which of the following is the best title for the passage?

A. The Importance of Developing Good Habits

B. The Significance of Planning Daily Activities

C. Ways of Distinguishing People we Spend Time with

D. Ways of Removing Time Wasters from Our Lives

2.The underlined word “sabotaging” in Paragraph 2 is closest in meaning to

A. promoting　　 B. offering

C. damaging　　 D. striking

3.What do we know about time wasters from the passage?

A. They fail to set clear goals for their life.

B. They arrange things on importance and need.

C. They turn away our attention from achieving goals.

D. They are addicted to sorting out the important activities.

阅读下面短文，根据其内容写一篇60词左右的内容概要。

Eighty-five percent of the jobs that today's students will do in 2030 don't exist yet,the Institute for the Future has predicted.That might seem like a high number to reach in only 10 years.But think about the non-mainstream careers that did not exist just a handful of years ago: social media manager,app developer and cloud computing engineer,etc.What role should colleges and universities play in preparing students for a workplace that is constantly changing? Educational institutions are trying to answer that question."We hope they will not only be prepared for whatever the job market looks like in 10,20 or 50 years but be the ones shaping it," said Jenn Stringer,professor at the University of Californian,Berkeley.Here are some of the approaches they're taking.

Some experts argue that the four-year learning model needs to be rethought in a big way. They say education can no longer be seen as something that stops when a person graduates from college.If students could take a year or two off school,get a job,and then return to school a few years later,the education system would offer true life-long learning and better adapt to changing technology.

Fewer employers are willing to train people on the job than the employers 50 years ago, largely as part of an effort to cut costs.To fill the job skills gap,some courses are offered as an add-on to a student's main degree.For example,the courses may include data analysis,web design and digital marketing.The goal is to offer students,a degree aside,some advantages when they seek jobs or promotions in the future.

Other institutions are trying to imitate the workplace within the traditional classroom. Several colleges have partnered with private companies,such as the software company Adobe, to integrate their products into the classroom.Professors at schools who partner with the company are encouraged to use the product for assignments.The idea is that students learn how to create a project that can be used in the real world and the"soft skills"such as teamwork and creativity.

Is there anybody out there? For centuries human beings have been wondering. As we've gained greater understanding of the universe, however, our searches have taken on a more concrete form. Questions about aliens have become a subject for science rather than science fiction and philosophy.

Now a new cooperation(合作)between the Very Large Array observatory in New Mexico and the privately funded Seti Institute in California could mean that our curiosity about aliens is closer than ever before to being satisfied. Data from the VLA's 28 giant radio telescopes will be fed through a special supercomputer that will search for distant signals. Scientists who work at the Seti Institute said the announcement means their research is now “almost mainstream".

How likely it is that a signal will be found, and what this might mean, are hard questions to answer. Seti's existing projects haven't detected any life signals from other planets so far. But recent discoveries in space and Earth sciences have provided some encouragement to those who are enthusiastic about the likelihood, however remote, of detecting other civilizations.

While once it was thought that our solar system could be unique, since the discovery of the first exoplanet (a planet in another solar system) in the 1990s, thousands more have been located(确定位置). Around one in five stars are now thought to have a planet in their orbit in a so-called “habitable zone"—that is at a distance from the star where the temperature(neither too hot nor too cold) means that life is theoretically feasible.

If there is another life form somewhere, could it be as intelligent as us? Or cause a risk to us, as the physicist Stephen Hawking once warned? As investigations of Mars continue, our interest in the possibility of alien life appears clear—especially when conditions in our own earth appear even more unstable.

1.What can we learn from the first two paragraphs?

A.Global cooperation helps to study aliens.

B.Searching for aliens is becoming a trend.

C.Aliens have caught wide attention globally.

D.There are many uncertainties about aliens study.

2.What is the encouraging news to searchers for distant civilizations?

A.VLA has developed new radio telescopes.

B.Seti has detected signals from other planets.

C.More and more exoplanets have been found.

D.Other civilizations have been located in a habitable zone.

3.What does the underlined word “feasible" in paragraph 4 most probably mean?

A.Possible. B.Tough.

C.Easy. D.Certain.

4.In which section of a newspaper may this text appear?

A.Literature. B.Health.

C.Education. D.Science.

Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

Many people are in the habit of pressing the “close” button because they don’t have the patience to wait for the lift doors to shut. But lifts’ “close” buttons are a complete scam (骗局), at least in the US － the doors will not close any faster no matter how hard you press.

It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

But to normal lift riders, the buttons aren’t completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

“Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “having a lack of control is associated with depression（沮丧）.”

Experts have revealed that a lot of buttons that don’t do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workplace.

Pedestrian(行人) crosswalk buttons don’t live up to their names either. Pressing them used to help make the traffic signals change faster, but that was before computer-controlled traffic signals were introduced.

But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

“That habit is here to stay,” John Kounios, a psychology professor, said. “Even though I have real doubts about the traffic light buttons, I always press them. After all, I’ve got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

1.What was the author’s main purpose in writing the article?

A.To analyze the functions of fake buttons.

B.To describe some different kinds of fake buttons.

C.To explore people’s different habits when it comes to pushing buttons.

D.To explain the advantages and disadvantages of fake buttons.

2.In America,the“close”buttons on lifts_______.

A.work only when people press them hard for a while

B.cannot speed up the process of closing the door in any case

C.are fake for the convenience of disabled people

D.were specially designed to give people a sense of control

3.The underlined part“for this same purpose”in Paragraph 6 refers to_______.

A.helping people to build up confidence

B.making people more patient

C.making people with depression feel better

D.giving people perceived control

4.According to John Kounios,people who press fake buttons______.

A.don’t know that what they press is fake

B.should give up this habit

C.consider what they do to be meaningless

D.probably do so to kill time

In a world where nearly 6 million fingerprint records of government employees are stolen in one computer hack, and here millions of people are victims of identity theft every year, the next step in cybersecurity may well be mapping your brain.

Researchers at Binghamton University, State University of New York are working on a biometric system that records how your brain reacts to certain images. With a little more polishing, the scientists’ brainchild could become the way you get into a safe deposit box, your office or past scanners at the airport. It could replace the password for your online banking, your email or your social media accounts.

The started their project by measuring the brain waves of 30 subjects, The subjects were fitted with a cap that had 30 electrodes attached to it, and then shown various images and symbols—celebrity faces, words, pictures of food—on a computer screen in 200- millisecond bursts. The brain's reaction was recorded.

The idea is that every time a person needs to use a “password”, he or she goes through the same procedure, and the results are matched with their first-time reaction. If the “brainprint”' is compromised—like what happened with the fingerprint records—then the system is merely reset by running another set of images and collecting a different set of brain waves. “Even if that was stolen, you could just cancel it and record one to something else”, says professor Laszlo.

Laszlo and her team have shown that their system can be 100 percent accurate. So one of the more difficult parts of making the system practical already has been overcome. Now they're spending much time recording accurate brainprints with as few as three electrodes, which could make recording in the future as easy as wearing a pair of special glasses. They're also working with cheaper material and methods to see if they can bring the cost down.

1.What does the underlined word “brainchild” in Paragraph 2 refer to?

A.The brain function. B.The fingerprint record.

C.The biometric system. D.The online password.

2.Why were the images and symbols shown to the subjects?

A.To create their brainprints. B.To check the brain's reaction.

C.To match brainprints with pictures. D.To connect brain waves to electrodes.

3.What are the researchers doing with the program now?

A.Making it user-friendly. B.Improving its accuracy.

C.Recording more brainprints. D.Increasing the number of electrodes.

4.Which's the best the title of this passage?

A.Brain waves—the necessity of passwords B.Biometric systerm—the hope of cybersecurity

C.Brainprint—the future of passwords D.Fingerpint—the challenge of cybersecurity

“Super-agers” have long puzzled scientists, but now researchers say they are unpicking why some people live beyond 80 and still appear to be well.

Researchers say studies show that super-agers appear to adapt more easily to the slings and arrows of life, and are more open-minded and less sensitive. But they have also made another discovery. Looking at the brains of 10 super-agers after they died, Prof Emily Rogalski, from Northwestern University said they discovered these individuals have more of a certain type of brain cell known as Von Economo neurons ( 神经) than average elderly individuals. “We can’t explain how they ended up with more Von Economo neurons or why that is important. But these are a special type of neurons that have only been found in a couple of regions of the brain.”

Studies have shown there are other differences as well. “When we look at the rate of cognitive ( 认知的) thinning in the cognitively average 80-year-olds, their brains are thinning at nearly two and a half times that of the super-agers,” said Rogalski.

Being underweight also seemed to matter, with those who had a very low body mass index after the age of 80 more likely to die. It’s not bad to be skinny when you’re young but it is when you’re old.

The researchers say they have also found that the common bad habits do not necessarily lead to an early grave, with many super-agers saying they smoked and enjoyed a drink. “We ask them why is it that you think you are a super-ager, how did you get here, and there are a couple of funny ladies and they will say, well it’s　 because I have some alcohol with my friends every day at 5 o’clock. Others have never had a drink,” said Rogalski.

However, Rogalski added, that did not mean that people should take up bad　 habits to live longer, noting that some people might have a genetic makeup that allowed them to tolerate smoking and drinking. Nonetheless, Rogalski thinks we can learn from super-agers. “We are getting quite good at extending our lifespan but our health span isn’t keeping up and what the super-agers have is more of a balance between those two, they are living long and living well,” she said.

1.What can we learn about Von Economo neurons?

A.They can be found all over the super-agers’ brains.

B.They lead to super-agers’ easier adaptation to hardships.

C.Super-agers are found to have more of them in their brains.

D.Scientists have discovered how they are produced in brains.

2.Compared to the average elderly, super-agers　 .

A.have better life habits

B.tend to drink more alcohol

C.are usually much slimmer

D.are slower in brain thinning

3.What does Rogalski intend to tell us by the underlined sentence?

A.We should develop good habits to live longer.

B.We should seek to live well while living long.

C.Super-agers should help us extend our health span.

D.Extending lifespan is harder than keeping health span.

4.What is the writer’s purpose in writing the passage?

A.To reveal some secrets of super-agers.

B.To introduce the ways of staying young.

C.To explain the advantages of living long.

D.To describe various habits of super-agers.
