A cellphone is one of the few things that we hold close to our faces all the time, and yet it could possibly explode - this is what made the recent Samsung’s Galaxy Note 7 smart-phone accidents so shocking.

According to technology news website The Verge, flawed（有瑕疵的）phone batteries might be to blame.

Even if you are not a science student, you probably know that it is common sense that the anode (the negative（负的）end of the battery) and the cathode (the positive end) should never touch. If they do, the battery will short-circuit（短路）, causing a powerful electrical reaction that can destroy the battery and cause a fire.

This is why all lithium-ion（锂离子）batteries - the kind that can be found in many of our devices like tablets and cameras - have a separator layer inside to stop the two ends from touching one another.

But somehow, the separators in some of the Samsung phones broke, causing explosions.

Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

The two “somehows” may sound random（随机的）and hard to explain. But they actually both come from the fact that phone producers have been pushing the limits of batteries to meet customers’ demand for a longer battery life.

According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers’ demand that their devices get thinner has also given producers little choice but to try to put more power into thinner batteries.

“The more energy you put into a box, the more dangerous it’s going to be,” Billy Wu, a lecturer at Imperial College London, told The Guardian.

A thinner battery also means producers have to use thinner material for separators, and thinner material has more chance of breaking.

1.A separator layer is put in lithium-ion batteries in order to ___________.

A. ensure a longer battery life

B. prevent a battery from short circuiting

C. connect the anode and the cathode

D. reduce a certain electrical reaction

2.What are the direct reasons for the Samsung phone explosions?

A. Short circuiting and overheating

B. Pushing the limits of batteries

C. Overcharging and thinner batteries

D. Automatic charging and broken separators

3.Lynden Archer’s comments indicate that ___________.

A. demands for thinner cellphones are unreasonable

B. lithium-ion batteries can’t hold much more power than that they do now

C. producers can use 10 percent of a lithium-ion battery

D. new material for batteries is needed to meet consumers’ demands

4.What is the writer’s main purpose of writing the article?

A. To describe problems facing cellphone producers

B. To explain the reasons for the Samsung phone explosions

C. To teach us common sense when it comes to batteries

D. To warn us about the dangers of lithium-ion batteries

We are humans, and we all make mistakes. The mistakes that we make are not usually on purpose, whether it is breaking a vase, or not completing a task. 1. This article will provide you with ideas as to what to do once a mistake has been made.

Admit that you make a mistake as soon as you discover it. Delaying it longer will only make you feel worse, or may drive you toward making the wrong decision to try and cover it up.

2. Do not play the “blame game”. Most people are smart enough to realize that this is just a poor attempt to protect yourself. Perhaps you gave a task to another person and it was never completed. But is it really the entire fault of the person you gave the task to or is it partially your fault for not following up? Keep this in mind before placing the blame on someone else.

3. Maybe you broke your mother’s favorite vase, or even forgot a friend's birthday. Just an apology can sometimes be viewed as a “quick fix”, and apologizing and asking to be forgiven gives the person opportunity to forgive you.

Offer some compensation(补偿) for loss, damage, or injury caused. 4. By doing this, it may soften the blow to the person we've disappointed.

Learn from your mistakes. In the case of a job or a task, write a "to-do" list with the deadline before leaving the meeting. As for forgetting a birthday, put the birthday on an electronic calendar for next year.

Do better next time. 5. We should try to understand what happened and try to make sure that it won’t happen again.

A. Take responsibility.

B. Never repeat your mistakes.

C. Apologize and ask for forgiveness.

D. People’s faith in us can reduce quickly.

E. So sometimes it is necessary to write a letter to say sorry.

F. But not everyone knows how to admit making a mistake.

G. Offer to immediately complete the late task or pay for the vase.

高二英语七选五中等难度题查看答案及解析

So we should all maintain an_______belief that the world is more forgiving than is commonly supposed.

A. optimistic　　　　　 B. instant

C. previous　　　　　　 D. imaginative

Many people believe that all ice cubes are created equal, but they are not. At least that’s what the folks at California’s Glace Luxury Ice Company would like us to believe. The Davisbased company says that the ice cubes they make are healthier and last longer than the ones that we throw into our drinks on a daily basis. What’s more, the company also says that their ice cubes do mot leave behind an aftertaste(余味)in drinks, like regular ones do.

In order to create these unique ice cubes, Glace Luxury begins with water that has been rid of the hazardous impurities(杂质)that the company says can lead to cancer and exist in regular ice. They then freeze it in large blocks. Once ready, the ice is carved into perfect cubes and each cube measures 2.5 inches across. Besides being healthier, these ice cubes apparently also take longer to melt. The company says that each ice cube can last up to 30 minutes.

Of course, those ice cubes do not come cheap. Those that wish to have a taste of this “tasteless” frozen perfection will have to pay $325USD for a bag of 50 ice cubes. That comes to $6.50USD for a single cube of ice!

The unique product is the brainchild of Robert Sequeira, a former business school lecturer who said that he wanted to establish a profitable business that could be easily scaled. Given that he can make as mush Glace Luxury ice as he needs for as little as $0.12USD per cube, he thinks that the idea certainly meets the standard. Now, if he can find that the few people can afford to buy this Glace Luxury ice, life would be great!

1.People at California’s Glace Luxury Ice Company probably want consumers to believe that _____.

A. ice cubes are healthy for people to use

B. their ice cubes add tastes to drinks

C. all ice cubes are created the same

D. their ice cubes are different

2.What does the underlined word “hazardous” in paragraph 2 mean?

3.Compared with regular ice cubes, the ice cubes created by Glace Luxury Ice Company_____.

A. taste much bette

B. look much more beautiful

C. have more different shapes

D. are healthier and melt more slowly

4.What does the author think of the ice cubes created by Glace Luxury Ice Company?

A. They will be a big success

B. They are too costly to make.

C. They are just regular ice cubes.

D. They are too expensive for consumers

Did you ever notice that when you’re fat, men don’t look you in the eye? They look across your shoulder. There’s no eye contact.

My name is Leslie. I am a real person. Up until two years ago, I was never looked in the eye by anyone.

I was too tired to be a lover to my husband. I was falling asleep by 8 o’clock most evenings. When I did go out for an evening. my husband was ashamed of me. And he said so to my face. When I walked, my thighs scrape together. I couldn’t even cross my legs. I was fat. Not just “overweight”. Fat! I was 5’55” tall and weighed 205 pounds.

About 18 months ago, my husband Darrell left a “Dear Leslie” letter on my bed and asked for divorce.

I went to a psychologist for advice. I knew that my weight was the source of my troubles. But I’d tried 14 different diets, at which I failed one by one.

He listened carefully and recommended an entirely different program. This was not a “diet.” It was a unique new weight-loss program researched by a team of specialists who help to treat the severely fat. I entered the program. Within the first four days, I lost only three pounds. So I was disappointed. But during the three weeks that followed, my weight began to drop from 205 pounds to 124 pounds. To me it was a miracle.

The reason why the program worked was simple. I was always eating. I could eat six times every day. I could snack in the afternoon. Snack before dinner. I could even have snack at night while watching TV.

How can you eat so much and still lose weight?

The secret is in the combination of foods, approved by the research team, which you eat in each 24 hour period. You will enjoy a variety of meats, chicken, fish, vegetables, potatoes, sauces. Even some light wine or beer if you wish. But be sure to have them in the right proportion（比例）, thus a complete 24-hour fat-reduction cycle is formed.

Without hunger, without nervousness, it lets you lose pounds so easily. Once you lose the weight, you’ll keep it off. Forever, I am sure of that.

Most people hold the belief that young people from poor families whose socio-economic backgrounds are not in bad conditions tend to do less well in the education system. In an attempt to help the children of poor families, a nationwide program called “Headstart” was started in the US in 1965. A lot of money was poured into it. It took children into pre-school institutions at the age of three and it was expected to help them succeed in education. However, the results have been disappointing, because the program began too late. Many children who entered it at three were already behind their peers in language and intelligence and the parents were not willing to get involved in the process.

To improve the results, another program was started in Missouri that concentrated on parents as the child’s first teachers. This program was based on researches showing that working with the family is the most effective way of helping children get the best possible start in life. The four-year study included 380 families who were about to have their first child and represented different social-economic status, age and family structure. The program invited many trained educators visiting and working with the parent or parents and the child. The program also gave the parents some guidance to communicate with their children, and useful skills on child development.

At the age of three, the children involved in the “Missouri” program were evaluated with the children selected from the same socio-economic background and family situations. The results were obvious. The children in the program were more advanced in language development, problem solving and other intellectual skills than their peers. They performed equally well regardless of socio-economic backgrounds or family structures. What they found through the program was that one of the most important factors that affected the child’s development was the poor quality of parent-child interaction. That interaction was not necessarily bad in poorer families.

The “Missouri” program is quite different from “Headstart” program. From what they did we can draw a conclusion: Without a similar focus on parent education and on the vital importance of the first three years, some evidence indicates that it will not be enough to overcome educational unfairness.

1.What can we learn about the “Headstart” program?

A.It helped many children from poor families to make progress.

B.It failed because the children they helped had already fallen behind.

C.It helped the children involved succeed in their education soon.

D.It succeeded in improving the intelligence of all the children.

2.We can learn from the second paragraph that the “Missouri” program ______.

A.focused on the children’s first school teachers.

B.helped the children return to the same home.

C.made the children improved in many aspects.

D.gave the parents advice on their development.

3.What does the underlined word “interaction” in Paragraph 3 probably mean?

A.Intelligence. B.Performance.

C.Education. D.Communication.

4.The last paragraph tells us that ______.

A.parents play an important role in children’s education.

B.it is impossible to overcome educational unfairness.

C.poor families cannot change the fate of their children.

D.The “Missouri” program pay more attention to the ages.

People hold the belief that a fun-filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often things that lead to happiness involve some pain.

As a result, many people don’t like the very attempts that are the source of true happiness. They fear the pain brought by such things as marriage, raising children, professional achievement, commitment(承担的义务)，self-improvement.

Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest, he will tell you that he is afraid of making a commitment, for commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most obvious features.

Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word “fun” to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

Understanding and accepting true happiness is one of the most liberating realizations because true happiness has nothing to do with fun. It liberates(解放) time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actully may not be happy at all.

1.According to the author, a bachelor resists marriage chiefly because____

2. The underlined word bachelor means_________

3.From the last paragraph, we learn that envy sometimes results from______

4.To understand what true happiness, one must________

5.What is the author trying to tell us?
