AN EXCITING TRIP

I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the center of Australia. He will soon visit Darwin. From there he will fly to Perth. My brother has never been abroad before, so he is finding this trip very exciting.

I suggest that he _________ a good dictionary. 

Read the text carefully, then answer the questions

In Western countries, electricity, gas and water are not luxuries but necessities. Company now realize that consumers want products that will not only work effectively, but also save money.

For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eight times longer. Therefore consumers can save about US$21 per bulb.

In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and stumble dryers. The label tells the consumers how much energy effectively each model has, compared with other appliances in the same category.

Ultimately, these innovations will save money as well as conserve the Earth’s resources.

If he _________ more money, he’ll have to do more work.
