If a traffic accident happens and someone is injured, the following steps can be used to treat the injured.In the first place, we should make sure that the accident scene is safe so that we won’t get hurt. We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds. If he is bleeding badly, it is vital that we should try to stop the bleeding by applying pressure to the injury. This is because if a person loses too much blood, he may die. If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.

The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply

知識探究（一）：普查與抽查像人口普查這樣，對每一個調查調查對象都進行調查的方法，稱為全面調查（又稱普查）。 在一個調查中，我們把調查對象的全體稱為總體，組成總體的每一個調查對象稱為個體。為了強調調查目的，也可以把調查對象的某些指標的全體作為總體，每一個調查對象的相應指標作為個體。問題二：除了普查，還有其他的調查方法嗎？由于人口普查需要花費巨大的財力、物力，因而不宜經常進行。為了及時掌握全國人口變動狀況，我國每年還會進行一次人口變動情況的調查，根據抽取的居民情況來推斷總體的人口變動情況。像這樣，根據一定目的，從總體中抽取一部分個體進行調查，并以此為依據對總體的情況作出估計和判斷的方法，稱為抽樣調查（或稱抽查）。我們把從總體中抽取的那部分個體稱為樣本，樣本中包含的個體數稱為樣本量。
