Easy Ways to Expand Your Vocabulary
Why expand your knowledge and use of words? 1., people will understand you more easily, and you will increase the concept that you are an intelligent person. Besides, learning new words is a fun activity.
Read, read, and read. The more you read — not only novels and literary works, but also magazines and newspapers — the more words you’ll be exposed to. 2., attempt to derive meaning from the context of the words as well as from looking up the definition in a dictionary.
Keep a dictionary handy. 3.. When you uncover a new word, look it up in the dictionary to get both its pronunciation and its meaning. Next, go to the dictionary and find similar words and phrases — and their opposites — and learn the slight differences among the words.
4.. Simply talking with other people can help you learn new words. Once you hear a new word, remember to take it down so that you can study it later — and then slowly add the new word to your vocabulary.
Learn a word a day. Using a calendar or website — or developing your own list of words to learn — is a great technique many people use to learn new words. 5..
A. Get involved in conversations
B. As you read and uncover new words
C. By using the tips outlined in this article
D. Use whatever versions you prefer
E. Because you’ll be able to communicate (speak and write) more clearly and precisely
F. Plus, keeping a journal of all your new words can provide motivation for learning even more words
G. This approach may be too rigid (死板的；僵硬的) for some people, so even if you do use this method, don't feel you must learn a new word every day
Vinegar is great. It makes salad, fries and dumplings taste better, and you can even clean your windows with it. And now, according to scientists, it may even help the plant’s population survive climate change. Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan proved that. They found growing plants in vinegar makes them more resistant to droughts. This could mean that in the future, worries about climate change affecting the world’s supply of food will be much lower.
The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought—like conditions, it produced a chemical called acetate (醋酸盐) — the main component of vinegar.
After discovering this, the scientists experimented further by adding acetate to the soil of other plants before they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died.
It’s hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive. “In the experiment, we targeted the staple foods of the world-rice, wheat and maize… and proved successful” Jong Myong Kim, co-author of the study, told Popular Science magazine.
Kim has already been in touch with people around the world who are interested in trying this simple and cost-effective method out for themselves from farmers to companies and amateur gardeners. “Now we are trying to cooperate with them to make a method to apply this system, and make the process as simple as possible,” he said. Hopefully, this means the end of hunger caused by bad weather in the future.

US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15℃ (59F) left hands as clean as water heated to 38℃ (100F).
National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University — New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water — given to the food industry in the US — held true. They asked 20 people to wash their hands 20 times each with water that was 15℃ (59F), 26℃ (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.
Prof Donald Schaffner said, “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”
However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.
In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various ways to make sure each surface of each hand is clean.
