Students who say they never or hardly ever use dictionaries often speak English well but usually write poorly, because they make many mistakes.

The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English.

The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables (音节), they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionary.

A. choose a good dictionary, and you’ll be successful in learning English

Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet’s health, and people’s health may be suffering from it.

The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content(含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn’t have fluoride(氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that’s behind the recent rise in bad teeth.

Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals(化学物质) into the water.

According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.

In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.

So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.

●Drink from your tap. Unless your government warns against this, it should be fine.

●Get a container(容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.

●Keep it cool. Don’t drink from a bottle that has been sitting in the sun, don’t store it near chemicals, and don’t reuse plastic bottles.

●Choose glass containers over plastic if possible. When finished, recycle!

1.What is the main idea of the article?

A. Drinking tap water is the only choice for people.

B. Glass containers are better than plastic bottles.

2.What can we learn about plastic bottles from the article?

A. They break down in less than 300 years.

B. They can be used for many other things.

C. They are a risk to the environment.

D. They are cheap to make.

3.According to the article, we can know that bottled water is ______.

A. no problem for the environment

B. more expensive than tap water

C. always safer than tap water

D. better for babies

Selfie

Social media and the mobile web have given rise to a strange phenomenon called the selfie(自拍). It refers to a picture of yourself, usually shared on any social networking website.

1. Some selfies are extreme close-ups(特写镜头), and others show part of an arm held straight outward. A few of them even feature the subject standing in front of a bathroom mirror.

Everyone takes selfies, but the younger crowd seems to be especially involved in the trend. Young people are relatively heavier digital users. They are interested in staying connected to their friends. 2.

There are also kinds of psychological factors driving people to take a selfie and upload it to a social networking site. 3. A quick and easy way to attract other's attention is to get "likes" and comments from friends. Secondly, it's human nature to show off your own great achievements. When you feel good about yourself or look good, it's far too easy to take out your phone and document it all through one or several selfies. 4. That's right. Sometimes people are bored at work, bored at school, bored at home and even bored on the toilet. Last but not least, social media is about being social! If that means uploading as many selfies as possible, then so be it. It's fun, and it's a cool way to sort of document your own life.

Finally, there are things to be mindful of when you're posting. It's easy to think you're sharing a photo with a few people. 5. So don't post anything online, selfie especially.

A. There are lots of selfie styles.

B. The rise of selfies has become universal.

C. Social media, to some extent, is the driving force of their selfie activity.

D. The desire to take, post and get "likes" on selfies goes back to a biological behavior.

E. But the whole world of social media is public and every individual can get access to it.

F. There are also people who will take selfies because they have nothing else better to do.

G. The leading factor is that people want to get attention from as many people as possible.

For long, there was a little boy with a bad temper. His father gave him a bag of nails and told him that every time he lost his temper, he would hammer a nail in the back fence.

The first day the boy had driven 37 nails into the fence. Then it gradually dwindled(逐渐减少) down. He discovered it was easier to hold his temper than to drive those nails into the fence. Finally the day came when the boy didn't lose his temper at all.

He told his father about it and the father suggested that the boy now pull out one nail for each day when he was able to hold his temper. The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence. He said, “You have done well, my son, but look at the holes in the fence. The fence will never be the same. When you say things in anger, they leave a scar just like this one. You can put a knife in a man and draw it out. It won't matter how many times you say I'm sorry, the wound is still there. A verbal (言语的) wound is as bad as a physical one. Friends are a very rare jewel, indeed. They make you smile and encourage you to succeed. They lend an ear, they share a word of praise, and they always want to open their hearts to us. Show your friends how much you care.”
