　　Unit 2　Growing painsⅠ.填词

　　Hair is one of the commonest parts of the body and something that is given a lot of attention.You’ve had it since birth and you take care of it every day.But how much do you know about your hair?

　　The average head of hair is made up of 120,000 strands(根)，each of which has a life expectancy of about three years.While some hairs are growing，others are resting，and others are falling out.

　　A hair is made up of two parts：the shaft(发丝)and the root.The shaft is a visible (or：seen) part.It has a complex structure.The root is the living part of the hair.It is here where cells develop and form the shaft.It also has a very complex structure.

　　Every day a normal head of about 120,000 hairs will lose between 50 and 100 hairs—or 30,000 hairs per year.Hair dies，falls out，and grows again.The life cycle is made up of three stages.First，a long and active growth period that lasts about three years—the hair grows.Second，a very short transition(过渡)period that lasts about three weeks，during which time the hair is inactive—the hair follicle shrinks.Third，a resting period of about three months—at the end of this period the hair is pushed out and lost.This cycle runs constantly throughout life.

　　A hair grows from 1 to 1.5 cm each month and its usual life expectancy is about three years.So very long hair is rarely seen.However，there are some people who do grow long hair.

　　The most common form of hair loss does not come from disease.In fact we can almost say it is a secondary sexual characteristic.It is called androgenetic alopecia(also known as pattern baldness)and results from a combination of genetic and hormonal(荷尔蒙的)factors.

　　There are two sorts of melanin(黑色素)present in all types of hair，in different proportions.These make it possible to get the different shades of color—blonde(or golden)，brown or red.

　　Some scientists say that the world’s oceans are slowly getting more acidic(酸)．

　　According to the researchers from California，the change is taking place due to higher levels of carbon dioxide(二氧化碳)in the air，whether you noticed it or not.

　　The lowering of the water’s PH value is not great at the moment but could make the living things in the sea in great danger if it continues，they warn.

　　Ken Caldeira and Michael Wickett，from the Lawrence Livermore National Laboratory，report their worries in the journal Nature.

　　Increasing use of petrol causes more carbon dioxide to go into the air，and most of it will eventually go to the seawater.Once in the air，it reacts to form a chemical to make the seawater acidic.Scientists believe that the oceans have already become a little more acidic over the last century.But these researchers have tried to work out what will happen in the future by analyzing what we know about the history of the oceans with computer models of climate change.

　　“This level of acidity will increase in the future if we continue letting carbon dioxide into the atmosphere，”said Dr.Caldeira.

　　It is not totally clear what that means for living things in the sea，however.There are still some conclusions we can draw.

　　Most living things live near the surface，where the greatest PH change would be expected to occur，but deepocean life forms may be more sensitive to PH changes.

　　Coral reefs and other organisms may be particularly affected，the scientists believe.The acid in the seawater will react on their shells.It could be much more difficult to build the shells in water with a lower PH.

　　In recent years，some people have suggested storing carbon dioxide in the deep ocean as a way of solving the problem of global warming(全球变暖)．

　　But Dr.Caldeira said the way should now be reconsidered.

　　“Decades ago，most experts had thought that it was good for the carbon dioxide to go to the sea—because when letting carbon dioxide into the air we warm the earth；and when carbon dioxide goes to the sea，it reduces the amount of greenhouse effect(温室效应)．”

　　Now scientists might be in a dilemma as to what to do.On the one hand，this proposal can help solve the problem of global warming.But on the other hand，it will make the sea more acidic.

　　About 10 years ago，a very successful businessman named Josh was traveling down a Chicago neighborhood street.He was going a bit too fast in his shiny，black,12 cylinder(汽缸) Jaguar XKE.

　　He was watching for kids rushing out from between parked cars and slowed down.Suddenly，a brick sailed out and—WHUMP！—it hit the Jag’s shiny black side door! Immediately Josh stopped the car，jumped out，seized the kid and pushed him up against a parked car.He shouted at the kid，“What was that all about and who are you? Just what the heck are you doing？！”Building up a head of steam，he went on，“That’s my new Jag，that brick you threw will cost you a lot of money.Why？”
