How to Learn English Well
All English learners want to improve their English, but as you know, it can be difficult! For you to learn, you need to work on all areas. The four main areas for you to focus on are: Reading, Writing, Speaking, and Listening. 1.
Speaking
This is the best way to learn English! There is nothing better than conversation to help you improve. 2. Also, get into the habit of thinking in English and don’t translate from your own language into English, which will slow you down. It’s fun to sing in English, so learn some English songs and sing your heart out!
Listening
3. Like speaking, it’s better for you to be in a totally English-speaking environment. It’s also good to watch TV shows, or movies in English. The news can be difficult to learn from for beginners, but the more you listen the more you'll pick up.
Reading
Reading English is something you can do to help you learn on your own, outside of the classroom. Have a dictionary with you to look up new words and then write them down in a notebook. 4. Newspapers are good for higher-level students, while lower-level students can try reading children’s stories or books which have been especially written for English learners. The Internet is full of stuff you can read and learn from.
Writing
Try keeping a diary. Start with small sentences and make them longer. 5. Try to make friends online, visit chat rooms, or post comments on blogs. These are all useful tools for you.
A. The four abilities are very important.
B. Here are some ways to help you learn.
C. Meanwhile, write or read some newspapers.
D. Again, the Internet is indeed a great way to help.
E. This really is a skill that needs to be worked on every day.
F. Using these new words in conversation is a great way to learn.
G. The quickest way to learn English is to be surrounded with English speakers.
Imagine a store where you could buy what you need using your plastic garbage. Not just food or household items but valuable goods such as minutes for your cellphone, WiFi and even health insurance.
This isn’t imagination for the future, or a strange society that uses trash for cash. It’s the idea behind Plastic Bank, a company formed in 2013 by David Katz and Shaun Frankson. As a diver, Katz was upset—and thus inspired to act—after he saw the shocking amount of plastic trash in the ocean when he travelled to other countries to dive.
Although important, simply cleaning up the oceans wasn’t enough, he decided. “To understand why, imagine walking into a kitchen to find the sink（洗碗池）overflowing and water pouring onto the floor. What would you do first? Turn off the tap.”says Katz. And he believes we need to turn off the tap for plastic junk and stop it from getting into the sea in the first place.
With Plastic Bank, people in parts of Haiti, the Philippines and Brazil can transform plastic trash into cash, goods or services. Collectors gather the plastic and bring it to a collection center to be weighed. In exchange, they’re paid in the form of cash, items from the store, or points that can be used at any store or recycling center that uses the Plastic Bank app; in some places, the points can also be exchanged for mobile money.
A collector can earn up to the equivalent of ＄ 5 a day, according to Plastic Bank. This can double or triple people’s real incomes. In Haiti, for example, the majority of the population earns below ＄ 2.41 a day.
After the collectors turn in their plastic, it is sent to a recycling center, where it’s sold to companies that use it in their products. Many businesses pay a premium（额外费用）for recycled plastic, in part to meet their social responsibility goals. But it can also benefit their bottom line-they’re able to tell consumers that by buying goods made with what Katz calls “social plastic”, their purchase（购买）benefits both the environment and people's livelihood.

It is interesting to see that the force of only 6 or 7 people pushing in the same direction can cause up to 1,000 pounds of force—enough to break brick walls. During a fatal stampede (蜂拥), people can even die standing up. People die when pressure is put to their bodies in a front to back direction, causing them not to be able to breathe.
If you are in a crowd, the first and most important thing is to make yourself familiar with your surroundings and find different exits. No matter where you are, make sure you always know how to get out.
Make yourself aware of the type of the ground you are standing on, and know that in a crowd of moving people wet ground can cause you to fall.
When in danger, a few seconds can make a difference, giving you the possibility of making use of your escaping route. Always stay closer to the escape route. If you find yourself in the middle of a moving crowd, do not fight against the pressure and do not stand still or sit down, because you can easily get trampled (踩踏). Instead, move in the same direction of the crowd; make use of any space that may open up to move sideways to the crowd movement where the flow is weaker.
Keep your hands up by your chest, like a boxer—it gives you movement and protects your chest. If you fall, get up quickly. If you can’t get up because you are injured, get someone to pull you up. If you have kids, lift them up. If you fall and cannot get up, keep moving in the same direction of the crowd, or if that is not possible, then cover your head with your arms; do not lie on your stomach or back.

Scientists in Colombia have trained a team of rats to help remove land mines from the countryside. Land mines are small bombs hidden in the ground and designed to explode(爆炸) when someone steps on them. When trained, the rats can smell special metals in the mines and then signal(发信号) to their human team. Then why use rats for such an important job?
In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.
The rats have already been used in Tanzania, an African country with many land mines. Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. “They even train their babies to perform their jobs, which saves us a lot of time, ” Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world. Last year, land mines killed 695 people — 56 of whom were children. A criminal group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia’s government. The group has placed mines all around its own bases and in many places in the countryside.
In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救). “These rats will be a great help,” he said.
1.How do rats help to find land mines?
A.By their special sight. B.By their light weight.
C.By their sense of smell. D.By their excellent hearing.
2.The advantage of rats over dogs in finding bombs is that _____.
A.they are cleverer.
B.they run faster.
C.they have a better sense of smell.
D.they don’t make mines explode as easily.
3.The underlined word “They” may refer to ______.
A.scientists. B.Wistar rats.
C.dogs. D.Méndez and her team.
4.What is the passage mainly about?
A.Specially-trained rats help clear land mines.
B.People in Tanzania are suffering from land mines.
C.Dogs are no longer used to find land mines.
D.Land mines have become a great danger to Colombians.
