8.Yuan Longping was born in Beijing in 1930.(61)Sincehe graduated from Southwest Agricultural College in 1953,he has devoted his life to(62)finding(find) ways to grow more and more rice.As a young man,he saw the great need for increasing the rice output.At that time,hunger was(63)aserious problem in many parts of the countryside.Yuan Longping searched for a way to increase rice harvests without expanding the area of the fields.In 1950,Chinese farmers could produce only fifty million tons of rice.In a recent harvest,(64)however,nearly two hundred million tons of rice(65)was produced(produce).These(66)increased(increase) harvests means(67)that22% of the world's people are fed from just 7% of the farmland in China.Yuan Longping is now circulating his knowledge in India,Vietnam and many other(68)less(little) developed countries to increase their rice harvest.Thanks to his research,the UN is trying to rid the world(69)ofhunger.Using his hybrid rice,farmers are producing harvests twice(70)aslarge as before.

分析 本文主要介绍袁隆平博士对中国粮食及世界粮食的贡献.1953年毕业于西南农大后,寻找增加稻子产量的方法就成了他毕生的目标.1950年中国农民稻子产量只有5千吨.但在最近的一次收成中,就有近2亿吨.这些增加的产量意味着占世界7%耕地的中国要供应占世界22%的人口的粮食.正是由于他的研究,联合国在和饥饿的斗争中多了选择的方法.用他的杂交水稻技术,农民得到的粮食收成多了一倍.

解答 61.Since 考查连词.根据句意:自从他1953从西南农学院毕业以来.用连词since.
62.finding 考查动名词.to是介词,后接动词时用动名词形式.
63.a 考查冠词.problem是可数名词,单数形式前加不定冠词a表示泛指
64.however 考查副词.however表示转折,尤其用于谈及一个既成事实时,表示转折,其意为"可是""仍然"等.可放在句首、句中或句末,通常用逗号与句子其他成分隔开.
65.was produced 考查动词时态和语态.rice与produce之间是动宾关系,且事情已经发生,要用一般过去时的被动语态.
66.increased 考查过去分词.harvests与increase之间是动宾关系,用过去分词作定语表示"完成"之意.
67.that 考查连词.mean后接的宾语从句是完整的,用连词that引导.
68.less 考查形容比较级."欠发达国家"用英语表示:less developed countries.
69.of 考查介词.rid of 意为"摆脱",是固定搭配.
70.as 考查固定句式.as…as意为"和…一样",表示同级的比较.使用时要注意第一个as为副词,第二个as为连词.其基本结构为:as+adj./adv.+as.

点评 在一篇200词左右的语篇(短文或对话)中留出10处空白,部分空白的后面给出单词的基本形式,要求考生根据上下文填写空白处所需的内容或所提供单词的正确形式,所填写词语不得多于3个单词.要做好语法填空题,理解短文是解题的前提,扎实的词汇、句型和语法知识是基础,英语国家的背景知识是必要的补充.考生须灵活运用语法知识,如单词词性、单词时态、名词单复数、连接词、代词、冠词等判断各空白处应填写的内容.答完后,还要通读全文,核对所填单词形式是否正确,是否符合语境.

18.I was headed out the door the other day with my two sons.We were going to drive to the local grocery store to pick up a few odds and ends that we had run out of during the week.I shut the door quickly because my dogs were already barking at being left behind in the house.We headed down the hill but when I reached into my pocket for the car keys,they weren't there.Shaking my head,I walked back up the hill and saw my keys still dangling from the hook(挂钩)where I always hang them.
This,of course,isn't the only time I have forgotten something recently.In fact,it seems to be happening more and more.There isn't a week that goes by that I don't forget something and then remember it later in the day or misplace something and have to go looking for it.The medical professionals all reassure(使…安心)me that this is a normal part of getting older.They say not to worry about it and to take it with a smile.I am doing my best to do so.
I think I will be alright with my forgetful mind too as long as I can keep remembering the important things in life.I don't mind misplacing my keys as long as I can remember that God loves me.I don't mind forgetting what I came into a room for as long as I can remember what I am in this life for.I don't mind being a bit absent-minded as long as I am being loving-hearted.
May you always remember the important things in life:You were created in love.You were created to love.You are called to kindness and made for joy.You can make a difference in this world with every choice you make.
