Topic Sentences

There were three reasons why I did not enjoy the school trip. Firstly, the journey to our hotel was long, hot and boring. Secondly, we spent all our time in museums doing boring worksheets. And thirdly, we had to go to bed really early. There are many things that ESL students can do to improve their English more quickly. They can join an after-school club which will give them the chance to practise spoken English while doing an activity that they enjoy. They can also watch films, particularly DVDs with the English subtitles turned on. Best of all, however, is to do plenty of reading for pleasure. Non-fiction in particular is an excellent way of acquiring a strong academic vocabulary. There were three reasons why I did not enjoy the school trip. Firstly, the journey to our hotel was long, hot and boring. Secondly, we spent all our time in museums doing boring worksheets. And thirdly, we had to go to bed really early. The school could do much more to protect the environment. I don't understand, for example, why we cannot use metal cutlery instead of plastic ones that just get thrown away after the meal. We could also have different trashcans to recycle paper and cola cans. We could also limit the number of copies that teachers and students are allowed to make on the photocopier machine. Topic Sentences Exercise 1.1 Underline the topic sentences in the following paragraphs. 1. Adventure Tourism Adventure tourism is a different way for tourists to see New Zealand. This type of tourism uses the plentiful natural resources - mountains, rivers, lakes, wilderness areas and historical sites to provide adventure, thrills and challenges which are low risk but high in excitement. For example, the coastal areas in New Zealand are great for canoeing and kayaking. White-water rafting is another popular water adventure tour. However, if you would rather keep your feet on the ground, New Zealand has over 100 developed walkways in addition to the tracks in the 12 National Parks. Because more and more tourists are interested in learning about New Zealand by doing exciting and unusual activities, adventure tourism will continue to grow. 2.Time Management No matter how you slice it, there are only 24 hours in a day. To be successful at university, students need to learn good time-management skills. The first skill is not taking on more than you can handle. If you are a working part-time, have a family and are involved in a community organisation, then taking a full course-load at university will be too much. Another time management skill is reasonably estimating the time required to perform each of the tasks at hand. For example, deeply reading a chapter from a course text cannot be completed in between television programmes. Finally, actually doing what needs to be done seems obvious, but is a very difficult skill. You may find that cleaning out your wardrobe becomes vital when you are avoiding study. Procrastination is a time manager's enemy. By learning time management skills your university study will be successful and most importantly enjoyable. 3.Have Heart The heart weighs about 11 ounces and is the size of a clenched fist. The heart of a man performs at about 60 to 80 beats a minute. In a year it beats some 40 million times. At each beat it takes in nearly a quarter of a pint of blood; in a single day it pumps 2,200 gallons of blood, and in the course of a single lifetime about 56 million gallons. Is there any other engine capable of carrying on such heavy work over such a long period of time without needing to be repaired? Obviously the human heart is a small yet highly efficient piece of equipment. Topic Sentences Exercise 1.2 Read the following paragraphs carefully.

Topic Sentences Exercise 1.3 The topic sentence of each of the following paragraphs has been omitted. After a careful reading, write your own topic sentence for each. This is the suggested topic sentence for this paragraph: Student success at university is the result of a number of inter-related factors. Topic Sentences Exercise 1.3 1. Factors in success at university _______________________ The most important factor is a student's past experience of study. If a student has already developed good study habits, study at university should not be difficult. Good study habits need to be complemented by interest and motivation, factors which are important when competition gets tough. We should however not underestimate the distracting effects of financial and personal difficulties. All students have to grapple with these at some stage of their university life. Beyond the personal factors it has to be said that there is also a certain element of luck involved in success: this includes finding excellent teachers and the subject matter that inspires one to give one's best. This is the suggested topic sentence for this paragraph: Whether genetic engineering indeed has the benefits promised for us all without the dangers remains open, but it is certainly here to stay. 2. Genetic engineering: no going back? Animal breeding for particular features may soon become obsolete with the new-found ability of scientists to work at the level of genes. On the one hand there are those who embrace the new bio-technology: genetic engineering. They argue that many genetic changes will be hugely beneficial and harmless. As long as safeguards are in place, they claim, humans would be foolish not to take advantage of the many benefits genetic engineering has to offer. Others have seen the speed with which gene manipulation can get out of hand, mixing species so that vegetable and animal are no longer distinguishable. They want to wind the clock back. But can they? _________________ Topic Sentences Exercise 1.4 In this exercise you are given topic sentences and two key points to include to support the topic sentence.

Two further key points suggested for a paragraph with the given topic sentence: ? New Zealand no longer so dependent on Australia and Asia ? increased interest in Spanish language and culture A paragraph based on the given topic sentence may look like this: New Zealand trade efforts have recently started to focus on South America as a new destination for our export products. There are several economic and even cultural beneifts to be gained from increased trade with South America. First, it means that New Zealand is no longer so dependent on Australia and Asia. Secondly, New Zealand gains the benefit of the many diverse trading opportunities that this huge region has to offer. Thirdly, since the major South American economies are stable and growing, trading opportunities are likely to increase. Lastly, more New Zealanders will become interested in this region and want to learn Spanish and enjoy cultural exchanges. Thus closer ties with South America will benefit New Zealand economically and culturally in the same way as has already happened with Asia.
