Unit 19 Modern Agriculture Reading MODERN AGRICULTURE
第19單元 現代農業 閱讀 現代農業
For thousands of years traditional agriculture in China did not change very much.
數千年來，中國傳統的農業耕作方式變化不大。
Most farms were one-family businesses.
大多數的農田用單一化農作物的耕作模式。
Although China is a very big country ,
雖然中國幅員遼闊。
only seven percent of the land can be used for farming.
但僅有百分之七的土地適于耕種。
It is on this arable land
就是在僅有適于耕種的土地上。
that the farmers produce food for the whole population of China.
農民們為全中國的廣大人口生產著糧食。
Farmers in China have long used techniques such as
中國的農民一直沿用技術諸如
fertilization and irrigation to make their land produce more.
施肥和灌溉等手段來提高土地產量。
Over time,many farming techniques have been modernized:
隨著時間的推移，許多耕作技術已經現代化了。
chemical fertilizers are now used and electric pumps are used in irrigation.
如今使用化肥和電力灌溉。
To make as much use of the land as possible,
為了最有效利用土地資源。
two or more crops are planted each year where possible.
可能的地方每年要種植兩種或更多的農作物。
Rice,cotton and vegetable seeds are sometimes grown in special seedbeds
有時，大米，棉花和蔬菜種子要在苗床培育
before they are planted in the fields.
然后移栽到農田中。
This saves time and allows farmers to grow an extra crop in each season.
這可以節省時間，讓農民在每個季節里再種一茬作物。
More advanced technical information was brought in from abroad in the 1980s.
更先進的技術知識是從20世紀80年代，從國外引進。
Import of technology and machines,and the international exchange of delegations
科枝和機械的進口，以及國際間的交流
have helped Chinese farmers improve their production.
幫助中國農民增加了產量。
It was from the early 1990s that scientists started to develop new techniques
從20世紀90年代初，科學家就開始開發新技術。
to increase agricultural production without harming the environment.
農業增產對環境無污染的。
Chemical fertilization,for example,help to produce better crops,but is harmful to the environment.
例如，化肥有助于增產，但它對環境有害。
New techniques should increase agricultural production but also be friendly to the environment.
新的技術必須既增加農業生產又有益于環境。
Future agriculture should depend on high technology as well as traditional methods.
未來的農業既必須依靠高科技又要依靠傳統的方式。
Not only is food production important but also taking care of the environment.
糧食生產是重要的但保護環境同樣重要。
The biggest problem of Chinese farmers is the shortage of arable land.
目前，中國農民面臨最大的問題是缺乏適于耕種的土地。
Using the latest technologies,Chinese scientists grow vegetables in greenhouses.
利用最新技術，中國科學家已能在溫室種植蔬菜。
The roots of these vegetables are not planted in earth
這些蔬菜不是植根于土
but hang in water that contains all the nutrients they need to grow.
而是吊掛在含有它們生長所需的各種營養水中。
Today,many vegetables are not grown in gardens but in greenhouses
如今，許多蔬菜不是生長在菜園里而是長在溫室里。
where they are protected from the wind,rain and insects.
他們不受到風雨和害蟲的侵襲。
The temperature is controlled with computers,no matter how the weather is outside.
溫室里的溫度由電腦控制，不管外面的天氣怎樣。
Another technique tries to create plants that produce more and bigger fruit.
另外一項技術是試圖開發能夠結出更多更大水果植物。
In 1993,a kind of tomato was developed
1993年，一種西紅柿問世了
that was very different from any grown before.
那是與普通品種迥然不同的。
It was developed using a technique known as GM.
它的開發靠的是一種叫做GM的技術。
"G" stands for"genetically "from the word "genes".
G代表"基因"，源自"基因一詞，
"M" stands for"modified",which means "changed".
"""M""代表""變更""。"
In other words,the way tomatoes grow from a natural seed is changed.
換句話說，西紅柿從自然種籽生長的方式改變了。
The new tomatoes are bigger and healthier.
新的西紅柿更大，更健康。
They can grow without danger from diseases.
這樣的西紅柿不會受到疾病的威脅。
They also need much less time to get ripe.
而且，它們生長成熟所需的時間要少得多。
The tomato is one of nearly 4,500 different plants that are genetically modified.
西紅柿是大約4500個不同品種轉基因植物中一例。
In China,about one hundred research stations
在中國，有大約100個研究所
are now doing GM research to make better tomatoes,cotton,tobacco,
正在從事轉基因的探索工作，以研制更好的西紅柿，棉花煙草，
green peppers,flowers,watermelons,soybeans,fish and of course rice.
青椒，花卉，西瓜，大豆，魚，當然還有水稻。
A variety of GM watermelons will be seedless
有一種轉基因的西瓜將是無籽的
and there is GM rice sometimes called "golden rice",
還有一種轉基因水稻，有時稱作“黃金水稻。
which will have more vitamins and can grow in poor soil.
它將富含維他命并可以在較為貧瘠的土豪中生長。
