问题 综合

2008年世界面临全球性粮荒问题。阅读下列材料,回答相关问题。(12分)

材料1:从2006年1月1日开始,联合国不再对华进行粮食援助。这不仅标志着中国26年的粮食受捐赠历史画上了句号,而且中国开始成为一个重要的援助捐赠国。但我们的粮食生产仍然存在着问题。截至2007年底,中国农村还有1479万人没有解决温饱,并且刚脱贫人口的后续发展能力与承受力都很脆弱。这些年来我国的耕地面积越来越接近18亿亩的“红线”。

材料2:世界三大粮食作物分布图。

(l)填出图例中字母代表的世界三大粮食作物名称:A________,B________,C________。(3分)

(2)从图中农作物的分布来看,主要农业地域类型有________、________、____。B作物主要分布区的农业地域类型与美国以种植业为主的农业地域类型的特点有何不同?产生这种差异的原因是什么?(6分)

(3)目前,我国还有1479万人没有解决温饱问题,而联合国不再对华进行粮食援助。在此种情况下,我国要实现粮食的自给,甚至成为一个重要的援助捐赠国,应采取的主要措施有哪些?(3分)

答案

(1)小麦   水稻   玉米

(2)季风水田农业   商品谷物农业   混合农业    B作物主要分布区的农业地域类型为季风水田农业,生产规模小,机械化水平低,商品率低,为小农经营;美国的农业地域类型为商品谷物农业,生产规模大,机械化水平高,商品率高,为家庭农场经背。产生这种差异的主要原因是社会经济发展水平、劳动力条件和气候等的不同。

(3)依靠科技进步,培育优良粮食品种.改造中低产田,提高粮食单产.合理利川土地资源,优化产业结构等。(3点即可)

三大根食作物从分布来看,小麦分布最广,如我国华北、美国中部地区等;玉米主要分布于热带和亚热带季风气候区;水稻主要分布于高温多雨地区。随着人口增多、经济发展以及耕地面积的不断减少,粮食问题日益严重,只有依靠科研,提高单产,才能保证粮食安全。

They came to the beach. To ease the sense of fear, he took a  35   of his father, then he put the camera aside and picked up the gun. His father said happily, “I’ve been  36  a long time for this day. I’ll let you  37 .” He leaned (屈身) forward, eyes narrowed. “There is a small flight(一群) now. Keep your head down; I’ll give you the  38  .”

Jeremy’s heart was beating  39  . “No, don’t let them come, please!” But they came, closer, closer... “Now, take them!” cried his father. Jeremy felt his body  40  . He stood up, leaned into the gun the  41  his father taught him. In the same distance, the ducks saw the gunners and flared (突然飞去) wildly. For a second he hung there balanced between life and death. There was no sound. Jeremy stood  42  , seizing the gun.

“What happened?  43   didn’t you shoot?” his father said in a controlled voice. The boy didn’t answer. His lips were trembling.

“Because they were so  44  ,” he said and burst into tears. He sat down, face buried in his hands and wept. All  45  of pleasing his father was gone. He had his chance and he failed  .

For a moment his father was  46  . And then he said, “Let’s try again.” Jeremy didn’t lower his hands. “It’s no use, I can’t.”

“Hurry, you’ll miss them. Here!” Gold metal touched Jeremy. He  47  up, unbelieving . His father was handing the camera to him, and said softly, “Quick!,” Jeremy stood up and pressed his shutter release(快门) button in a flash. “I got them!” His face was bright.

Jeremy saw that there was no disappointment in his father’s eyes,  48  pride and love. “I’ll always love shooting. But that doesn’t mean you  49  . Sometimes it takes as much   50  not to do a thing as to do it.”  He paused. “I think you could teach me how to operate that camera .”
