Прежде всего, какие виды живых существ ученые относят к вымирающим? Вымирающие животные — это такие виды организмов, популяция которых на данный момент имеет очень низкую общую численность в результате воздействия разных неблагоприятных факторов. К сожалению, следует признать, что вредным влиянием практически всегда является либо непосредственная деятельность человека, направленная на уничтожение этого вида, либо создание невозможных для его выживания условий. Разумеется, на все организмы люди воздействуют в той или иной степени, однако не все они вымирают. Виды живых существ попадают в категорию “вымирающие животные”, если наше отрицательное влияние слишком интенсивное. Также это происходит, если у групп живых организмов, например, имеются особенности физиологии, связанные с излишне длительным созреванием взрослой особи или малым количеством потомков. В результате вид, на который воздействуют вредные факторы внешней среды, не успевает воспроизводить себе подобных, численность сокращается и он вымирает.
There are four seasons in a year: winter, spring, summer and autumn. All seasons are good in their own way. Winter, for example, is full of celebrations, presents and snow. Spring is the time of nature awakening and flower blooming. Autumn can be rainy and yet beautiful, full of multi-coloured leaves.
However, my favourite season is summer. I choose summer not only because my birthday is in June, but also because it’s the time of holidays. Summer is the season when the sun shines brightly, the sky is rarely cloudy and the water in the sea becomes warm enough to swim. Even if it becomes too hot, you can always go for a walk in the shady woods. I also like summer because there are many berries, fruit and vegetables, not to mention numerous flowers on the fields. Among them roses, dandelions, daisies, and other flowers. Sometimes the air in summer becomes stuffy, but occasional thunderstorms bring relief. After the thunderstorms the air becomes remarkably fresh and very often we can see the rainbow in the sky.
Summer is also the time when I and my family go on holiday to the seaside. It’s a wonderful time, when we can have a rest from the intense academic year and relax. I think all children love summer because of long school holidays and I’m no exception. I also enjoy my free time, playing with my friends, watching TV, and doing other fun activities. Nevertheless, I don’t forget to do some useful reading from time to time.
