The line graph demonstrates the incomes of three Australian car retail companies, Acme Sports Car, Branson Motors and Curtis Car Mart, in month for the 1994 financial years.
Acme Sports Cars made large profits in the first quarter. Its profit is A$70000 in beginning, and after a slight decrease, the number climbed to A$ 80000. However, there was a dramatic reduction during the next quarter, which was maybe caused by the execution of the luxury goods tax. Attributed to the Australia economy boost, the fourth quarter witnessed a boom after the increase of the third quarter.
As for the Branson Motors, its profit kept raising in the first two quarter A$ 40000 in Sep 94 and about A$ 70000 in Dec 94 separately. Then, there was a fluctuation in the third quarter. Despite of the boost in economy, the amount of profit increased by A$ 10000 only. The income of Curtis Car Mart reached its bottom (A$20000) in Sep 1994. But an obvious rising up to A$ 80000 in Jun 1995 was showed in other three quarters.(173)

Raising pets has existed for hundreds of years in human civilization history. It is one of the proofs that animals and human being live together in the earth harmoniously. But some opposite arguments say that raising pets costs too much, moreover, dangerous and dirty are unavoidable. Disadvantages are definitely brought, in my view, and meanwhile advantages accompany obviously.
Disadvantages of having pets primarily present in the three aspects as follows. First, some citizens love their pets so much that their normal family relationship has been ignored. To some extent, the deterioration of family relationship will influence the stabilization of the whole society. Second, as the criticism says, if overmuch dollars are spent in pet food, toys and treatment, it is a waste of money indeed. In addition, nobody can promise that their lovely puppies will never hurt themselves and others.
However, there are several advantages that pets give us. Trained dogs have been employed to be nurses and guiders for blind man. Their contributions to human will never be forgotten. Furthermore, in order to cultivate children's personalities and teach the to cherish the life, teachers always suggest parents buy some rabbits and cats and raise with their children. At last, reports expressed that pets can help the senior citizen and some mental illnesses patients.
As for the question whether too much money are spend on pets, in my opinion, the phenomenon have not gone that worse. Nevertheless, I strongly support that much attention should been paid to pets and establishment of correct relationship between pets and masters are essential. (259)

The graph demonstrates the changes of acid levels in mouth caused by eating fruit sugar, cane sugar and honey sugar separately with time elapsing. It can be seen that PH value is used to describe the level of acid and PH 5.5 is the boundary of decay happening.
As you can see, when you eat any kind of these three categories sugars, the acid levels in mouth decrease quite quickly, and all will reach their lowest points in 5 minutes. Whereas, their lowest values are different, PH3.5 for honey, about PH4 for fruit sugar and PH4.7 for cane sugar approximately.
The PH value of honey nearly levels off in the period between 5 minutes and 10 minutes. Then, there is a obvious increase trend in the PH value until 25 minutes elapsing. After that, the value reaches 7 and remains steady. The one thing we give attention is that it is at 13 minutes point that the PH value is equal to PH 5.5.
In contrast to the honey sugar, though the acid level begin to decrease 5 minutes later, the influences of cane and fruit sugar to your tooth are by far worse, since the PH value need more time to exceed the safe value PH5.5. As for cane fruit sugar, the PH value is over PH5.5 after 20 minutes you eat them and increases to 7 in 35 minutes. What is the worst is that the cane sugar makes your tooth in decay state more than half an hour.
So we can conclude that, through the analysis above, the honey sugar is the safest sugar, while the cane sugar affects your tooth most.
超大法了,晕!!!

The steps of technological development never halted before in the civilization history of humankind. Even greater advances in technologies, which involve electronic engineering, telecommunication, medicine, computer science, and so on, have been witnessed in the 20th century. Among these fast developing technological domains, in my view, computer science should be the one that influence the humankind most and has made a considerable number of traditional life modes and behavior modes of human changed. However, these changes are both in positive direction and negative direction.
Why do I support the notion that the evolution of computer science is the most important technology? The reasons are mainly presented in two aspects. Initially, it is the computer science that has bought the global boom of productivity. Undoubtedly, productivity is the drive force of the human society in essence. Therefore, the progress of productivity motivates will motivates the advancement of human society entirely.
In addition, computer science has effected our daily life so enormously that there is not another technology surpass it so far. It dose change our life and enter every corner of our life indeed. Without computers, you would not withdraw you cashes from ATM machines, which means more time would be spent in queue in bank counters. Another example, the complex procedures of industry would never be controlled precisely, as most of them are out of human capacities and are hazardous. In one word, our life is more convenient and comfortable by far, contributed to the help of computer science.
Unfortunately, accompanied with merits, negative affects of computer science come into our sights. The wide utilization of computer in factories replaces thousands of workers, which promote the unemployment rate and lead to the instability of society at last. Moreover, computer games that the youth are easily addicted to are always the focus of criticisms.

From the first graph, we can see that, in the Republic of Freedonia, male labor forces occupied more positions than women in all of the working sectors in 1975. For example the in the public (***) sector more than 200000 worker were male labor forces, in contrary, the figure for female decreased to less than 50000. A considerable number of workers engaged in public sector(non****) and retail trade area, approximate 8300000 male and 630000 female for public sector (non ***) and about 650000 male and 670000 female for retail trade area. There are about 300000 female employed in manufacturing sector, however, the number doubled for the male employer. At the same time, a little gap was presented in communication sector.
What we can observe from the second graph is that more women workers were recruited in retail trade, communications and finance banking sector in the year 1995. Especially, overcoming the number of male working, female workers hold more positions in communications and retail trade sectors. While, the percentage of different gender workers in manufacturing and pubic sectors(non***) kept steady. More and more female workers joined the finance/banking sector and the distance with male workers reduced obviously and the same trend can be find in public sector(***)
Through the analysis and description above, we draw a conclusion that the number of female worker had gained an enormous growth over the twenty-year period.
