一、完形填空
Dear Mr Jones,
I expect you may be slightly surprid to receive a letter from someone living as near as your nextdoor neighbor, but I have to rai a subject so that it will be easier for me to discuss in writing.
You may have noticed that I have a __1__ of apple trees running alongside the fence that __2__ our two gardens. You may also have taken __3__ in the frequent sight of your two children __4__ on your lawn directly by the fence. And you may also have __武夷山大王峰5__ that my apple trees, so to speak, bend over the fence and em to __6__ your children with interest.
It is only natural that your children should sometimes em to return that __炒白术的功效与作用7__. And it is not only natural, __8__, I acknowledge, quite legal, for them occasionally to show that interest by __9__ all the apples that hang over on __10__ side of the fence.
But to be plain with you, Mr Jones, I am tired __11__ eing your children, day after day, tear the branches off the side of every one of my apple trees, and leave my trees looking __12__ a battle had been fought on one side of them. I am, if anything, even more tired of waking up the fine autumn __13__, to find even the apples on my side of the fence __14__ in number. I know this is the work of your children, since last night I was woken at midnight by the __15__ they were making __16__ one of my trees, and (as they may have told you) chad them home.
While I am on the subject, I am at least grateful to you for keeping your bonfires on the far side of your garden this year. Last year neither I __17__ your children had any apples, becau the smoke from your bonfire destroyed all the flowers__18__ the apples had time to form. I very much hope that next year—for the first time since I came to this village—I shall have my apples, and your children __19__ have theirs and that the sight of the line of apple trees will be __20__ pride to us both.

Dujiangyan is the oldest manmade water system in the world, and a wonder in the development of Chine science. Built over 2,200 years ago in what is now Sichuan Province in Southwest China, this amazing engineering achievement is still ud today to irrigate over 6,000 square kilometers of farmland, take away floodwater and provide water for 50 cities in the province.
In ancient times, the region in which Dujiangyan now stands suffered from regular floods caud by overflow from the Minjiang River. To help the victims of the flooding, Li Bing, th

e region's governor, together with his son, decided to find a solution. They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.
The simplest fix was to build a dam, but this would have ruined the Minjiang River. So instead Li designed a ries of channels built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing naturally. Better still, the extra water could be directed to the dry Chengdu Plain, making it suitable for farming.
Cutting the channels through the hard rock of Mount Yulei was a remarkable accomplishment as it was done long before the invention of gunpowder and explosives. Li Bing found another solution. He ud a combination of fire and water to heat and cool the rocks until they cracked and could be removed. After eight years of work, the 20metrewide canals had been carved through the mountain.
