Firefly is just a name.They are actually very cool insects. And they are not even flies, they are beetles.They have a way of sending out light signals every now and then.If you see them at night on a tree, you might think it is a brightly lit Christmas tree.That is the kind of light these fireflies produce. But the light they send out does not have heat,like the bulbs we use.The firefly's light is cold. Aetually these beetles could be the most efficient bulbs if only we knew how to use them. For almost all the energy they produce gets changed into bright lightcool light. How do they do it? The back portion of their stomachs are transparent.There are cells of crystals or chemical substances inside which get broken down by enzymes.Some energy is released in the form of light. The fireflies send out 1ight signals at fixed intervals.And the purpose behind it is to attract beetles for mating.But one firefly's signal is different from another's, depending on its sex and the type of family it belongs to.If a firefly sends a signal at a fixed interval but gets a response either too soon or too late,it will ignore the signal.It is like a perfect dance sequence.If you are faster or slower than your partner,the dance fails. Fireflies come from two families of beetles.One family of fireflies is usually found in Europe.North Ameriea and Australia.They are found on trees.The other family of fireflies is found in the Pacific islands.There is another type of beetle which gives out a softer 1ight.It is called the glow worm. Which of the following would be the best title for this passage? A) Insects and Beetles B) Bulbs and Fireflies C) Strange Christmas Lighfs D) The Cool Firefly

One day when I was driving on the freeway, I noticed all the way there were large dividing walls, which had been built between it and the road running parallel to it, for noise reduction and a sense of separation. The purpose was to create a sense of privacy for people on the other side. This got me thinking: How often do we put up mental barriers that keep us distant from others? Lifting the artificial barriers that keep us apart can offer opportunities to express our goodwill and create better relationships. If we can do like this, maybe our life will be a little different. There is a little post office in a nearby town, and since it is closer to me than the post office in my own town, I go there. One day, with many people jammed into the little building, a man came hurrying in to mail a letter, and the girl at the counter saw he had too little postage on it. She told him he needed 2 more cents. Obviously he was a little at a loss. He had hurried over from his office, and didn't have any money on him or time to stand in line. He was going to run back to get the needed money and wait in line again, but he hurried to get the letter mailed in the first place. As we were watching him, one woman volunteered a two-cent stamp, and the whole line became very quiet. It was a beautiful moment. The man hesitated for a little while and asked her if she was sure, and she assured him she was fine with giving him the stamp. He offered to go back to his office to get the two cents, and she told him not to bother. It was a small thing, but it meant something to both of the people involved, and to the rest of us. We aren't a yard that needs defining or a freeway that needs barriers. We are human beings who can contribute to each other's wellbeing by taking time to pay attention and interact. After all, we are all parts of a whole living in society. What happened after the man being told he needed two more cents? A) The man went back to his office immediately. B) The man turned to a lady for help. C) A woman offered a stamp to the man. D) The man waited in line patiently.
