In spite of the advances made in agriculture, many people around the world still go hungry.Why is this the case? What can be done about this problem?
Despite [“尽管”，介词，后面接名词] the development of agriculture, famine still exists globally. This miserable situation happens for at least a couple of reasons; however, fortunately, it does not have to persist [（顽固地）存在，不及物动词].
The first reason is that [名词性从句作表语-表语从句] although farming and breeding have developed, the prices of agricultural products have not accordingly been reduced to affordable levels. It is not farmers to blame. As a matter of fact, after a harvest is reaped, it is collected by traders before shoppers can choose the produce [“农产品”] on the shelves of markets. Those intermediary businesses [“中间商”], including retailers[“零售商”] , raise the prices to profitable [“有利润的”]levels that are often too high. Another reason is the inaccessibility of some areas. The inconvenience transportrenders these areas out of reach of modern vehicles, and therefore, foodstuff cannot arrive where it is needed.
One solution, in response to [“应对于”] the first reason above, is toregulate food prices and make basic foodstuff affordable for all people. For example, legislators [“立法者”] could intervene in [“介入干预”（褒义）]the pricing process and curtail the profits that may be excessive [“过度的”]. If [“如果”，条件状语从句] food prices could drop to reasonable levels, every household would afford enough food to feed every mouth. Another solution, to the second reason above, is to develop transportation. Since [“因为/既然”，引导原因状语从句] some regions whose food supply depends on imports may not have proper infrastructures [“基础设施”]of transport, such as roads, rail lines or airports, facilities must be constructed to ensure food delivery.
In conclusion, although agriculture has been progressing [“进步/进展”，不及物], many people, around the world, still starve. A minimum of two reasons can account for [“解释”] this phenomenon, and two corresponding solutions are proposed.

The two maps illustrate the planned changes of a university’s sports center based on its current conditions.
First, the entrance hall and the reception area will be expanded, with a sports shop and a café in the west and east corners. However, the central area of the premises will not change enormously, except that the gym will be extended eastward. The 25-meter swimming pool, the changing room and the seating space will remain the way they are.
Immense changes will happen to the outdoor courts that are now independent of the central area. Replacing the west court, a leisure pool and a changing room on its south will be built. The east court will also be removed, and where it is now, there will be a number of facilities. First, a sizeable sports hall will share the wall with the seating area of the 25-meter pool. Second, directly opposite the sports hall, there will be a pair of dance studios. In addition, a changing room, closely adjacent to the café, will be built in the southeast corner.
Overall, the sports center will have greater versatility.
