PART  4        Questions 35-40

Today’s maple syrup

The trees

• Tree trunks may not have the correct 35                          until they have been growing for 40 years.

• The changing temperature and movement of water within the tree produces the sap.

The production

• Atapis drilled into the trunk and a 36                          carries the sap into a bucket.

• Large pans of sap called evaporators are heated by means of a 37                          .

• A lot of 38                          is produced during the evaporation process.

• ‘Sugarsand’ is removed because it makes the syrup look 39                          and affects the taste.

• The syrup is ready for use.

• A huge quantity of sap is needed to make a 40                               of maple syrup.

38、跟上一题并列，题干用evaporation process做定位，题干is  produced出现被动原文可能出现主被动的转换，预判答案填名词。对应原文： The    evaporation process  creates  large  quantities  of  steam.Creates  对 应 题 干 的 is     produced,large quantities  of 对应题干的a  lot  of,答案为steam.

39、定位用sugar  sand,syrup,taste,预判答案填形容词，对应原文:'sugar sand'has to be filtered out as this builds up during the boiling and gives the syrup a cloudy appearance,be filtered out 对应题干中is removed,appearance对应题干中的 look,  答案填cloudy.

40、定位用sap,maple syrup,根据题干预判答案为名词，对应原文：It takes 40 litres of sap to produce one litre of maple syrup.40 litres of sap对应题干中a huge quantity of sap,maple syrup原文原词出现，答案填litre.
