雅思閱讀中確定主干的重要性

 在之前的文章當(dāng)中，胡一美老師為大家分享了很多關(guān)于相關(guān)的解題方法和技巧，如果同學(xué)們需要，可以翻看我們之前的文章。今天新通教育西安胡一美老師為大家分享的是閱讀中確定主干的重要性及確定主干的方法，希望能給同學(xué)們的雅思備考帶來幫助。

在中句子理解是非常重要的 ，特別是絕對句子主干的把握以及定位詞的確定。

我們要清楚的知道誰干了什么事，誰對誰有影響。這是對我們基本功的最基本考查。

我們還是拿的一道真題來說。

29 What does "moisture deficit" mean to the grain and crops?

A The growing condition will be very tough for crops.

B The growing season of some plants can hardly be determined.

C There will be a huge gap between the water plants needed and the water the earth can offer.

D The soil of grain and crops in New Zealand reached its lowest production since 1970s.

題目"moisture deficit"對莊稼意味著什么，也就是說對他們有什么影響?我們要找到句子的主干。moisture deficit is imposed at different growth stage of crops. 真正有兩者的是moisture deficit is imposed at different growth stage of crops.，所以我們應(yīng)該繼續(xù)往下看。 it will cause about 22% reduction in grain yield as opposed to moisture deficit at vegetative phase.會造成糧食的減產(chǎn)。情感色彩消極，所以答案應(yīng)該是A。因為A體現(xiàn)了二者關(guān)系且情感符合。

A選項 農(nóng)作物的生長條件將是非常艱苦的。

B有些植物的生長季節(jié)很難確定。

C 在植物所需的水分和地球所能提供的之間將會有一個巨大的缺口。

D 新西蘭的谷物和農(nóng)作物的土壤達到了自20世紀70年代以來的最低產(chǎn)量。

Among all the calamities posed by drought, moisture deficit ranks the first. Moisture deficit is the gap between the water plants need during the growing season and the water the earth can offer. Measures of moisture deficit were at their highest since the 1970s in New Zealand. Meanwhile, ecological analyses clearly show moisture deficit is imposed at different growth stage of crops. If moisture deficit occurs around a crucial growth stage, it will cause about 22% reduction in grain yield as opposed to moisture deficit at vegetative phase.

在所有由干旱造成的災(zāi)害中，缺水排在第一位。水分虧缺是指植物在生長季節(jié)所需要的水分與土壤所能提供的水分之間的缺口。新西蘭的水分虧缺指數(shù)達到了上世紀70年代以來的最高水平。同時，生態(tài)分析清楚地表明，水分虧缺存在于作物的不同生長階段。如果水分虧缺發(fā)生在關(guān)鍵的生長階段，將導(dǎo)致糧食產(chǎn)量減少約22%，而不是營養(yǎng)階段的水分虧缺。

下面是個句子 ：大家看下主干是否都可以確定呢?

Moreover, in addition to its being a transportation pathway equipped with a mammoth physical plant of tracks signals, crossings, bridges, and junctions, plus telegraph and telephone lines, the railroad nurtured factory complexes, coat piles, warehouses, and generating stations, forming along its right of way what has aptly been called “the metropolitan corridor” of the American landscape.

而且，鐵路除了是裝備有龐大的路軌信號廠、十字路口、橋梁、交叉點以及電報和電話線的運輸路徑外，還產(chǎn)生了聯(lián)合工廠、服裝大樓、倉庫和發(fā)電站，在它的沿途形成了美國風(fēng)景中被恰如其分地叫做“都市走廊”的景象。

雅思閱讀確定主干的必要性想必大家已經(jīng)了解，舉個不是很恰當(dāng)?shù)乩�子，抓住�?dāng)中的主干就相當(dāng)于擒賊先擒王，抓住了主干就算大家的理解有偏差也不會太夸張，所以同學(xué)們一定要加強自己的對文章主干的明感性，多多聯(lián)系哦。新通教育西安為大家提供課程，還有新春定制的春節(jié)班課，優(yōu)惠多多，同學(xué)們千萬不要錯過哦�；蛘邠艽螂娫�400-618-0272咨詢。
