Ⅰ.閱讀理解

• 1．In Scotland，600，000 tonnes of food are thrown away every year.This amount of food，which could feed about 1.2 billion poor people，is almost a third of household（家庭的） waste.And food waste isn't just a big problem in Scotland.
     Money，time，and resources are often wasted by throwing away good food.It also causes very harmful greenhouse gas，which is perilous to the planet.
     In the production stage，some foods do not enter the food chain for many reasons.Supermarkets usually care about the quality of food from farms.They often refuse strange-looking and unusually sized produce.However，they seem to forget that it is almost impossible to grow the perfect produce.Food waste at the consumption（消費(fèi)） stage includes food going out of date and leftovers（剩飯）because of too much food.In households，even mostly fresh fruit and vegetables are thrown away.
     In order to reduce food waste，here is what we can do：
     Understand the terms "use by" and "best before" dates."Use by" dates are there for your safety.It is dangerous to eat food after the use-by date and doing so risks your health."Best before" dates tell you how long the food will be at its best quality.Once the food passes the date，it isn't necessarily bad，but you should still check，just to be sure.
     Every time you go shopping and bring back new food，put them at the back of your fridge and bring the food that will expire（到期）soon closer to the front.That way，you know what needs to be eaten first.
     If you have any food that will expire soon，give it to charity if you aren't going to eat it.They will really appreciate the food you have given.

  A．Food waste is the biggest part of household waste.

  B．Place food carefully according to its expiry date.

Ⅲ.概要寫作

• 4．閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要。
      Environmental problems are becoming more and more serious all over the world.For example，cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories.Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore，wherever we go today，we can find rubbish carelessly disposed（處理）.
      There are different kinds of pollutants，each of which comes from different sources.It is necessary to identify the source of pollution，in order to make a policy to get rid of them.Different products，processes and activities of our industrialized world together form the major source of pollution.
      The forms of pollution can be mainly divided into three kinds-solids，liquid and gas.These pollutants have greatly damaged our planet and continue to do so.In fact，pollution is threatening our existence.The whole ecological balance of the earth is changing.Massive destruction of environment has brought about negative effects and even posed a great threat to man's existence.
      We must face the situation that exists and take action to solve our environmental problems.For instance，new laws must be passed to place strict control over industrial pollution；the public must receive the education about the danger of pollution and raise their awareness of protecting the environment and so on.
      The earth is our home and we have the duty to take care of it for ourselves and our later generations.Fortunately，more and more people have realized these problems.Measures have been taken to deal with these situations by the government.And laws have been passed to stop pollution，I hope the problems will be solved in the near future and our home will become better and better.
