正如上面兩張曲線圖所示，從1990年到1995年蛋類的平均價格不斷上升，并且其需求量也相應增加。曲線圖還表明，從1995年到20xx年期間蛋類價格下降，而且需量也下降。這種現象是很奇怪的并值得研究。根據市場經濟法則，需求量增加會引起價格上漲。也就是說，當價格上升時，需求就下降，而當價格回落時，需求就增加。但是現在的現實恰好相反。
產生這種奇怪的現象的原意是很明顯的。從1990年到1995年期間隨著我國社會主義市場經濟的發展，人民的收入，其中包括工資、獎金和各種補貼迅速增加。雖然蛋類價格的.需求量也急趨增加。另一方面，當蛋類的需求達到某一點時，需求量就停止上升，因為人們開始把越來越多的錢花在衣著、娛樂和國內外的旅游上。普遍認為，從1995年到20xx年旅游開支占我國人民總消費量的很大一部分。因此，同期蛋類需求量的下降也似乎是合理的。
我的看法是，由于家禽養殖業的不斷發展，蛋類價格很可能下降，因為對蛋類的需求有限，消費量的下降也是必然的。
as is shown by the two graphs above, the average price of eggs was on the rise from 1990 to 1995 and the demand for them increased correspondingly. the graphs also indicate that during the period from 1995 to 20xx the price eggs declined, and so did the demand. the phenomenon is quite strange and worth studying. according to the law of market economy, the increase in demand results in higher prices. that is to say, when prices climb, the demand decreases, and when prices fall, the demand grows. now the reality was just the other way round.
the reasons for this strange phenomenon are obvious. during the period from 1990 to 1995 with the development of our socialist market economy people＇s income, bonus and different kinds of benefits, increased rapidly. though the price of eggs rose gradually, the demand for them grew sharply, too. on the other hand, when the demand for eggs reached a certain point, it stopped rising because people began to spend more and more money on clothing, recreations and tours round the country and even round the world. it is generally assumed that the expenses for tours accounted for a great part of the total consumption of the people in our country from 1995 to 20xx. as a result, it seemed reasonable that the demand for eggs declined during the same period of time.
as far as i＇m concerned, with the domestic poultry farming continuing to develop, the price of eggs is likely to decline because the demand for them is limited and the fall in consumption of them is also inevitable.(270 words)
