③ 初中英語作文沙塵暴是怎樣形成的
沙塵暴的形成需具備4個條件。
一是地面上的沙塵物質。它是形成沙塵暴的物質基礎。
二是大風。這是沙塵暴形成的動力基礎，也是沙塵暴能夠長距離輸送的動力保證。
三是不穩定的空氣狀態。這是重要的局地熱力條件。沙塵暴多發生於午後傍晚說明了局地熱力條件的重要性。
四是乾旱的氣候環境。沙塵暴多發生於北方的春季，而且降雨後一段時間內不會發生沙塵暴是很好的證據。
春季沙漠的邊緣地區，由於長期乾旱，而且地表少有植被覆蓋，當有大風來臨的時候地表的沙塵很容易被吹起且被輸移，但由於沙子粒徑較大，不易形成懸移(懸浮移動，是小顆粒物質保證長距離輸移的必要條件)，因此不能長距離輸移，這也是距沙塵較遠的地區只有降塵而少見揚沙的主要原因。如果風持續的時間很長，形成懸移的浮塵能夠被輸送到很遠的地方，所經過的地區就會出現沙塵暴；當風速減弱到一定程度後，浮塵就會降落，該地就會出現降塵天氣。如果此時降水，就會形成所謂的「泥雨」。
從沙塵暴形成過程所需的4個條件看，黃土高原、廣袤的沙漠及由人為因素的破壞正處於荒漠化過程中的土地，北方春季末耕種的土地及處於施工過程中的基礎設施(如高速公路等)為沙塵暴的發生提供了充分的物質源；而春季北方地區的乾旱，又使沙塵暴發生的可能性增強；大風的產生是一種復雜的大氣現象，主要是冷鋒活動或經緯向環流調整作用的結果。由此可見沙塵暴的產生是多種復雜因素共同作用結果，人類活動對自然界的破壞導致土地荒漠化的加劇，對沙塵暴發生產生了極其重要的作用，而近幾年全球乾旱(其原因目前尚未知)等異常天氣現象也對沙塵暴的發生起了不可估量的作用。所以說人類活動對沙塵暴的產生只起到一定作用，並不能說沙塵暴就是人為因素造成的。
The formation of the sandstorm to have the four conditions.
One is the st on the ground material. It is the material basis of form sandstorm.
2 it is winds. This is the power of the formation, is fundamental to the power of the sandstorm long-distance transport of guarantee.
Three is not stable air condition. This is an important local thermal conditions. Sandstorm occurs more often in the afternoon that incorporates the evening the importance of thermal condition.
Four is the dry weather environment. Born in the north of the sandstorm multiple spring, and rain after a period of time within a won't happen very good evidence is st storms.
The edge of the desert in the spring, e to long drought, and surface vegetation cover, when there is little wind comes on the surface of the earth is easy to be blowing st and sand, but e to lose move large particle size, is formed not easily movable (suspension movement, it is small particle material guarantee to lose the necessary conditions of long distance move), and therefore can not move long lost, this is far from the st in the st and rare only micrometeorology main reason. If the wind last time is very long, form the st suspended loads can be transported to a very far place, through which areas will appear sandstorm; When the winds weaken to certain degree, floating st will the landing, the st weather will appear. If the precipitation, can form the so-called "NiYu".
The formation process from the four conditions look, the loess plateau and vast desert and by the destruction of the human factors in the process of desertification is in the land of the north, at the end of the spring farming land and in the construction process of infrastructure (such as high speed road, etc.) for the st storm occurrence providing full source material; And the spring drought in the north, and the likelihood of the sandstorm strengthened; The winds generated is a complex phenomenon, mainly is the cold air activities or to the circulation of the regulatory role longitude results. This shows the generation of sandstorm is DuoZhong complex factors results of human activity on the natural world to disruption of the desertification intensifies, st storms happen to have an important role, and in recent years the global drought (the cause isn't yet known) abnormal weather phenomenon also to the st storm occurrence have played an important role. So that human activities for the generation of st storms only play a role, and can't say st storms are caused by human factors.

Nowadays sandstorm becomes such a serious problem. It pollutes the air and disturbs the daily lives of people.
I think we should solve this problem as soon as possible. My suggestions are as follow: for one thing, more funds ought to be put into trees planting and forest protection so as to keep more water resources within the surface of the earth. For another, governments of all countries should found some laws concerning environmental protection.
Everyone knows that there is only one earth, lf we go on destroying her, it won』 be fit for us to live in any longer. Now it』s time for us to love her, take good care of her and cure her.
