Selecting the right person for the job involves more than identifying the essential or desirable range of skills, educational and professional qualification necessary to perform the job and then recruiting the candidate who is most likely to possess these skills or at least is perceived to have the ability and predisposition to acquire them .This is a purely person /skill match approach to selection.

plan .Identification of this plan makes it possible to differentiate dinosaurs from any other types of animal , even other archosaurs（祖龙，古蜥） . Most significantly, in dinosaurs, the pelvis and femur had evolved so that the hind limbs were held vertically beneath the body, rather than sprawling out to the sides like the limbs of a lizard. The femur of a dinosaur had a sharply in-turned neck and a ball-shaped head, which slotted into a fully open acetabulum (吸盘，关节窝)or hip socket. A supra-ace-tabular crest helped prevent dislocation of the femur. The position of the knee joint, aligned below the acetabulum, made it possible for the whole hind limb to swing backwards and forwards. This unique combination of features gave dinosaurs what is known as a ‘fully improved gait’. Evolution of this highly efficient method of walking also developed in mammals, but among reptiles it occurred only in dinosaurs.

It is widely believed that because cats prey on native birds they could bring about their extermination. But predation seldom leads to extinction in such a simplistic way. If it did there would be no animals left in Africa, as those big cats called lions would have eaten them all up.

i. Decrease in food yields
ii. Drop in yield affected by reduction in research iii. Pollution ruining crops
iv. World at risk due to predicted food shortage v. Lack of international interest vi. Bid to retain Asian farmers vii. Desperate situation for Asian
viii. Environmental degradation due to changed farming methods
ix. Need to increase soil fertility
x. Population explosion compounds Asian problems xi. International commerce threatens Asian agricultural xii. Food shortages have wide effects
From the mid 1960s when the Green Revolution began, Asian food production doubled through a combination of high-yielding crops, expanded farming area and greater intensification. From now on, growing enough food will depend almost entirely on increasing yield from the same, or smaller, area of land. However, a mysterious threat is emerging in the noticeably declining yield of rice from areas that have been most intensively famed. Unless scientists can unravel why this is so, food output in Asia may actually stagnate at a time when population will double.

List of headings
i. Responsibilities of responding police officers ii. Perceived advantages of rapid response iii. Police response to public satisfaction
iv. Communicating response time to people requesting help v. When rapid response is and is not necessary vi. Role of technology in improving police response vii. Response time and success of response viii. Public demand for catching criminals ix. Obstacles to quickly contacting the police
It becomes clear that the importance of response time in collecting evidence or catching criminals after a crime must be weighed against a variety of factors. Yet because police department officials assume the public strongly demands rapid response, they believe that every call to the police should be met with it. Studies have shown, however, that while the public wants quick response, more important is the information given by the police to the person asking for help. If a caller is told the police will arrive in five minutes but in fact it takes ten minutes or more. Waiting the extra time can be extremely frustrating. But if a caller is told he or she will have to wait 10 minutes and the police indeed arrive within that time. The caller is normally satisfied. Thus, rather than emphasizing rapid response, the focus of energies should be on establishing realistic expectations in the caller and making every attempt to meet them.
