How to save drowning people. C. There is a mon ,usually round object that you can see every day and it appears in many expressions—buttons! Buttons, which are made of metal or plastic, are found on all sorts of clothing. They fasten or connect one piece of clothing to another to make sure your clothes don’t fall off. To be cute as a button is an old saying, which means to be attractive or sweet, but in a small way. Babies are often described as cute as a button. Language experts don’t know why. But they do say the expression dates from the late 1860s. Here is another expression associated with button: buttondown. People often wear buttondown shirts to the office. Buttondown as an adjective means to be conservative. People described as buttondown stay as close as possible to the normal way of dressing and behaving. When buttoning a button, you slip it into a buttonhole. A buttonhole traps the button. So, to buttonhole someone means you have trapped him in a spoken conversation. Now, let’s say you find yourself buttonholed in a conversation at a party. Someone just keeps talking and talking and talking! Finally, you can’t stand it any longer. You tell him to button it! This is a direct, but a little rude way of saying “Stop talking!”Button your lip is another equally rude way to stop a person who talks too much. Another kind of difficult person is someone who pushes one’s buttons. To push one’s buttons means to know how to get that person annoyed or upset.

Learns of one’s secret. C. Gets someone to lose his temper. D. Argues with someone. D. As we all know ,trees are important to our life. They provide us with food, wood and most importantly, oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria in water. The discovery was made by some scientists and high school students who were seeking for a natural water filter(過(guò)濾器 )—one that could help people in developing countries that don’t have access to modern water systems.[來(lái)源 :Zx x k .Co m] The researchers, led by Rohit Karnik, a professor ,decided to turn to trees for help because they were able to allow liquid to flow through while blocking out air bubbles(氣泡） . They began by cutting sections of tree bark from the branch of a white pine tree. The researchers then tested the wood’s filtering ability by pouring water containing red dye particles(染料顆粒 )of different sizes through. To their surprise, they found it was effective in trapping all the particles. Encouraged, the team did another experiment, this time with water containing bacteria. Sure enough, the bark held back 99%of the bacteria, allowing only 1% to flow through. Mr. Karnik said the bark was able to filter water containing much smaller particles.
