Many strong spirits have been broken by it. It springs from the lips of thoughtless people each morning and robs us of the courage we need that day.

As a result, we often miss the love ing from the other end.Love is a telephone which is seldom programcontrolled or directly dialed. You cannot get an immediate answer with a simple “hello”, let alone go deep into your lover’s heart with one call. Usually it has to be relayed by an operator, and you have to wait patiently.Love is a telephone that is always busy. When you are ready to dial for love, you only find, to your disappointment, the line is already being used by someone else.Love is a telephone, but it is difficult to know when to dial. You will miss the opportunity if your call is either too early or too late.Passage 23 JealousyThe experience of jealousy varies enormously from age to age, from culture to culture, from couple to couple, from person to person, and can be different within the same person from time to time. In the United States, there has been a change of attitude toward jealousy in recent years. “Normal” jealousy, which has been seen as an inevitable acpaniment of love and support of marriage, has e to be seen by some as evidence of personal insecurity and weakness in the relationship, and therefore a threat to the partnership.Most jealous flashes e from feeling left out of an activity involving your partner and another person or other people. When your partner pays attention to another, your first reaction is to note that they are “in” and you are “out”. You feel excluded, ignored, unappreciated.This kind of experience is not unmon, and dealing with it gracefully is part of the etiquette of our time.Passage 24 Differences Between Television and Radio AnnouncersWhen television first began to expand, very few of people who had bee famous as radio announcers were able to be equally effective on television. Some of the difficulties they experienced when they were trying to adapt themselves to the new medium were technical. When working on radio, for example, they had bee accustomed to seeing on behalf of the listener. This art of seeing for others means that the mentator has to be very good at talking. In the case of television, however, the announcer sees everything with the viewer. His role, therefore, is pletely different. He is there to make sure that the viewer does not miss some point of interest, to help him focus on particular things, and to help him understand the images on the television screen. Unlike his radio colleague, he must know the value of silence and how to use it, at those moments when the pictures speak for themselves.Passage 25 The African ElephantThe African elephant, the largest land animal remaining on earth, is of great importance to African ecosystem.

Passage 19 Little Boy’s Big IdeaThe Intellectual Property Owner Association (IPO) is running a project to encourage young inventors. Samuel Houghton, a fiveyearold boy has bee the youngest Briton to hold a patent after watching his father struggling in the garden. Samuel developed a garden tool after watching his father Mark use two brushes to sweep up leaves outside their house. His father used a large brush to gather leaves and small branches, and then got a small brush to pick up what was left. Samuel came up with the idea for a laborsaving tool, which has been patented and named the Improved Broom.It is a simple idea that bines two ordinary brooms with differentsized bristles and brushheads to enable differentsized dirt to be swept up more efficiently. “The small one gets the first bits and the one at the back gets those left behind, Samuel explains.The IPO says that Samuel is its youngest known patent holder.Passage 20 Cultural DifferencesMeeting people from another culture can be difficult. Different cultures emphasize the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in small talk, usually over a glass of tea, before they do any job.In many European countries—like the UK or France—people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar value。t just sit on a cloud and wait for the girl he39。 the tall trees make a canopy of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds. Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is a deliberate tactic to prevent the spread of any tree diseases and make life more difficult for leafeating insects.They are not called rainforests for nothing!
