Объяснение:

от легкого венозная кровь превращается в артериальную(за счет кислорода) далее кровь с кислородом поступает из капилляров в венозные сосуды, которые, соединяясь, образуют в каждом легком две легочные вены, впадающие в левое предсердие.

как читается текст по английскому языку CLIMATE

But recently the climate has changed a lot in our country especially in its European part. Some scientists think the woria as becoming hotter. If you compare Moscow's winter and summer term peratures at the beginning of the century and at its end, you will see that the climate has really changed. Winters have become war er. Sometimes there is little snow in January, and there were win- ters when it rained (not snowedl) on the New Year's Eve. Many people say that it is so because of the greenhouse effect. Have you ever heard about it? It works like this: sunlight gives us heat, Some of the heat warms the atmosphere, and some of the heat oes back into space. Nowadays the air surrounding the earth has ecome much warmer because the heat can't go back into space. That's why, winter and summer temperatures in many places have become higher.
