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 本文主要介紹袁隆平博士對中國糧食及世界糧食的貢獻.1953年畢業(yè)于西南農大后,尋找增加稻子產量的方法就成了他畢生的目標.1950年中國農民稻子產量只有5千噸.但在最近的一次收成中,就有近2億噸.這些增加的產量意味著占世界7%耕地的中國要供應占世界22%的人口的糧食.正是由于他的研究,聯合國在和饑餓的斗爭中多了選擇的方法.用他的雜交水稻技術,農民得到的糧食收成多了一倍.

解答 61.Since 考查連詞.根據句意:自從他1953從西南農學院畢業(yè)以來.用連詞since.
62.finding 考查動名詞.to是介詞,后接動詞時用動名詞形式.
63.a 考查冠詞.problem是可數名詞,單數形式前加不定冠詞a表示泛指
64.however 考查副詞.however表示轉折,尤其用于談及一個既成事實時,表示轉折,其意為"可是""仍然"等.可放在句首、句中或句末,通常用逗號與句子其他成分隔開.
65.was produced 考查動詞時態(tài)和語態(tài).rice與produce之間是動賓關系,且事情已經發(fā)生,要用一般過去時的被動語態(tài).
66.increased 考查過去分詞.harvests與increase之間是動賓關系,用過去分詞作定語表示"完成"之意.
67.that 考查連詞.mean后接的賓語從句是完整的,用連詞that引導.
68.less 考查形容比較級."欠發(fā)達國家"用英語表示:less developed countries.
69.of 考查介詞.rid of 意為"擺脫",是固定搭配.
70.as 考查固定句式.as…as意為"和…一樣",表示同級的比較.使用時要注意第一個as為副詞,第二個as為連詞.其基本結構為:as+adj./adv.+as.

點評 在一篇200詞左右的語篇(短文或對話)中留出10處空白,部分空白的后面給出單詞的基本形式,要求考生根據上下文填寫空白處所需的內容或所提供單詞的正確形式,所填寫詞語不得多于3個單詞.要做好語法填空題,理解短文是解題的前提,扎實的詞匯、句型和語法知識是基礎,英語國家的背景知識是必要的補充.考生須靈活運用語法知識,如單詞詞性、單詞時態(tài)、名詞單復數、連接詞、代詞、冠詞等判斷各空白處應填寫的內容.答完后,還要通讀全文,核對所填單詞形式是否正確,是否符合語境.

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(掛鉤)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.
