Помогите переводом текста Secretion is a process generally brought about by an organ called a gland. A gland whether simple or complex in structure may be looked upon as a tube whose walls are composed of highly specialized epithelial cells, gland cells. The tube is closed at the end. In many glands the other end of the lumen opens up, either directly or by means of a special duct, onto a free surface, such as the skin, the in terior of the mouth, etc. The materials produced by the gland are poured onto this free surface, for which reason the secretion of this type of gland is spoken of as an external secretion. The gland is sur rounded by a dense network of capillaries. The distinct process takes place in a gland: the gland cell serves as a transfer agency or it acts as a manufacturing plant or both. In the first instance, certain materials, water and NaCl are taken out of the cell, passed into the duct and secreted on a free surface. All types of glands transfer water in this manner. Other glands take certain materials out of the blood stream and chemically transform them into new compounds, they then being poured into the duct. The activity of the gland is normally accompanied by a great dila tion of its blood vessels. Without this increased flow of blood a gland cannot function for any appreciable length of time. Nevertheless in many instances its blood flow in itself is not the direct cause of secretion, for by administering certain drugs it is possible to stop the secre tion completely although the flow of blood continues.
Read the text below and look carefully at each line. Three of the lines are correct, and the others have a word which should not be there. Put a tick (v) if the line is correct or write down the odd word. • The first is done for you. It just happened on one day. We woke up and everything was purple:[on] 1. the people, the animals, everything you could see, even the sea and the sky. 2. We looked in the amazement. Were we dreaming? Was everything really 3. purple? At first it seemed strange, then it seemed funny, even the king 4. and queen were purple, but no one could explain what had happened. Although 5. the scientists did tests and argued about the results for months, they couldnt 6. find the answer to the mystery. As time went by it was got boring in our purple 7. world. We had sat down to eat our purple food, looking at the purple faces 8. across the table. At the school, our purple teacher taught a class of purple 9. children, who has came to school on their purple bikes. One day we saw a 10. strange bird - it was yeilow, so yellow it hurt our eyes. We were all so been used to violet. 11. The bird flew down to rest on a tree and the tree turned back on to its old 12. colour with the green leaves. Slowly the grass under the tree became green again. Ответить
Read the text and answer the question. More than one answer may be correct. We spend about one-third of our lives sleeping, and when not dreaming, we аге completely without consciousness. Even the humble fruit fly sleeps while some creatures, such as dolphins, sleep with half their brain at а time. Sleep matters: go one night without it and we suffer the next day; go too long and we would die. As we fall asleep, the rapid electrical activity found in normal waking fades away and slow, deep waves start coursing throughout the cortex. Most sensory input is blocked and nerve signals to muscles are interrupted, preventing us from acting out our dreams. Despite this, the brain remains almost as active as when we are awake. Sleep is usually divided into three stages of increasing depth, plus the "rapid eye movement" (REM) stage in which brain activity is similar to waking and most dreams occur. There are many theories about why we sleep. Some researchers think sleep helps consolidate memories from the previous day. Others believe it rebalances neurotransmitter levels. Dreams are even more mysterious. Freud believed that they represent wish fulfillment of the subconscious. А more recent theory argues that they are just the brain making sense of its own activity when cut off from the world. Dream consciousness is different from normal consciousness. When dreaming, we easily accept bizarre events, show reduced self-awareness, and generally lack experiences of volition. This may have to do with lower activity in the prefrontal cortex during dreaming. And dreaming is not limited to REM sleep – dream reports are also common after waking from early "slow wave" sleep, though these dreams are relatively static, snapshot-like images and usually lack а "self" character. What happens when we fall asleep, according to the text? 1)The rapid electric activity is shifting deeper into the brain stem 2)The brain ignores most information coming from the periphery 3)Higher levels of neurotransmitters such as dopamine are being released 4)The cortex is experiencing slower electrical activity 5)Nerve signals cannot affect muscles 6)Brain shuts itself off from the rest of the body
