题目内容

11．A new school ___________ in the village last year．（　　）

A．

built

B．

is built

C．

was built

D．

has built

分析去年村里建造了一所新的学校．

解答答案：C．主语a new school是动词build的承受者，构成被动关系，结合last year表达的是过去的事情，故用一般过去时的被动语态was/were+过去分词，主语单数，故was，build的过去分词built，故答案是C．

点评被动语态由"助动词be+及物动词的过去分词"构成．被动语态的时态变化只改变be的形式，过去分词部分不变．疑问式和否定式的变化也如此．

Vitamin A helps to protect skin from becoming dry．It is also helpful to the eyes．Without vitamin A，you cannot see well in darkness．Vitamin A is found in animal liver and yellow part of eggs．Sweet potatoes，carrots and other dark colored fruit and vegetables have something that the body can change into vitamin A．

Vitamin B helps to produce red blood cells．It is found in foods like eggs，meat，fish，milk and green leafy vegetables．

Vitamin C is needed for strong bones and teeth，and for healthy blood vessels（血管）．It also helps wounds to heal（意合） quickly．The body stores little vitamin C，so we must get it in foods like oranges，and cabbage．

Vitamin D increases the levels of calcium（钙） in the blood．Calcium is needed for verve and muscle（肌肉） cells to work normally，as well as to build strong bones．Fish liver oil has vitamin D．In some countries，milk producers add vitamin D to milk so that it will be good for children．

3．Pollution means adding dirty or harmful（有害的） things to land，air，water and so on．
As a result，they are no longer pleasant or safe to use．Pollution is bad for animals and plants，and it even makes people's health in danger．In our daily life，we can see different kinds of pollution in many places．There are three main forms of pollution：land pollution，air pollution and water pollution．
    Land pollution is caused by solid waste，such as cans，bottles and some plastic things which aren't broken down quickly．It makes the environment look very bad．However，air pollution is more serious than land pollution．It is much worse in cities and towns because of the fumes（废气） from traffic and the waste from human（人类的） activities．When people drive their cars，fumes which are most made up of CO2，NO2 and SO2 are given off．After the gases get into the air，they may mix wit h clouds．Then they will become some harmful chemicals falling on the ground with rain．It is one of the reasons for soil erosion（土壤侵蚀） which is one example of water pollution．
    Various kinds of pollution will cause many health problems．People have realized they must change this serious situation．There are many ways to control pollution．To develop alternative energy（替代能源）is very popular in many countries．China，for example，has made up its mind to be a leader in this field．It is trying hard to make full use of energy from the sun and wind．It has paid plenty of money to make electric cars and trains instead of traditional traffic．We should also take action to make our environment cleaner every day．Take cloth bags while going shopping and drive cars less．We have only one earth．We must take small steps no w to help protect our environment for the future wherever we are．
