of leaves. (C10-T3-R2 T15)

  原文: the tree saves its precious resources and discards them.
  同义替换:
    drop --- discards
 
3. 题干:A suggestion that the red colouration in leaves could serve as a 

warning signal.
原文:they might act as a chemical defence against attacks by insects or 

fungi.
  同义替换:
  Serve as a warning signal --- act as a chemical defence
 
4. 题干:The most vividly coloured red leaves are found on the side of the 

tree facing the 19 __________ . (C10-T3-R2 T19)
原文:the most reddest are those on the side of the tree which gets most sun.

     原文:Not only that, but the red is brighter on the upper side of the 

leaf.
     同义替换:
  Contain the most red pigment --- the red is brighter
  Surface --- side
 
6. 题干: Red leaves are most abundant when daytime weather conditions are    

21_________ and sunny. (C10-T3-R2 T21)
原文:It has also been recognized for decades that the best conditions for 

intense red colours are dry, sunny days and cool nights, conditions that 

nicely match those that make leaves susceptible to excess light.
     同义替换:
  Most abundant --- intense red colours
  Daytime --- days
 
7. 题干:The intensity of the red colour of leaves increases as you go 

further 22__________ . (C10-T3-R2 T22)
原文:And finally, trees such as maples usually get much redder the more 

north       you travel in the northern hemisphere.
     同义替换:

  freezing.
     同义替换:

9. 题干:The ‘light screen’ hypothesis would initially seem to contradict 

what is known about chlorophyll. (C10-T3-R2 T24)

light-absorbing chemical, from too much light.

10. 题干:Leaves which turn colours other than red are more likely to be 

damaged by sunlight. (C10-T3-R2 T25)
原文:What is still not fully understood, however, is why some tress resort 

to producing red pigments while others don’t bother, and simply reveal their 

orange or yellow hues. Do these trees have other means at their disposal to 

prevent overexposure to light in autumn? Their story, though not as 

spectacular to the eye, will surely turn out to be as subtle and as complex.
     同义替换:
     Turn colours other than red --- simply reveal their orange or yellow 

hues.
     To be damaged by sunlight --- overexposure to light
 
11. 题干:How leaves turn orange and yellow in autumn. (C10-T3-R2 T26)
原文:This unmasking explains the autumn colours of yellow and orange, but 

not the brilliant reds and purples of tress such as maple or sumac.
  同义替换:
Turn orange and yellow in autumn --- the autumn colours of yellow and orange
 
12. 题干:How herbivorous insects choose which trees to lay their eggs in. 

(C10-T3-R2 T26)

同义替换:
How herbivorous insects choose --- if insects paid attention to such 

advertisements
