As I held my father's hands one night, I couldn't help but notice their calluses (老茧) and roughness. His hands tell the story of his life as a1, including all his struggles.

    One summer, I remember, a drought (旱灾) hit Ontario, turning it into a 2desert. On one of those hot mornings I was picking sweet com with my dad to fill the last3from the grocery store. Fifty dozen was all we needed, which4took twenty minutes. That morning, however, the process didn't 5quickly. After forty minutes of aimlessly walking in the field, we6 needed twenty dozen. I was completely frustrated (挫败的) and7. Dropping the basket heavily, I declared, “If the store wants its last twenty dozen, they can pick it themselves”. Dad8. “Just think, my little girl, only ten dozen left for each of us and then we're9.” Such is Dad----whatever problem he 10 he never gives up.

    11  the bad effects of the drought were felt all over our county. It was a challenging time for everyone,12Dad remained optimistic (乐观的). He 13to be grateful for other things like good health and food on our plates. Only then did I truly begin to 14Dad and his faith that guided us through the hard times.

某超市对今年前两个季度每月销售总量进行统计，为了更清楚地看出销售总量的总趋势是上升还是下降，应选用____ 统计图来描述数据．

阅读材料，回答下列问题。

材料一 新疆是我国最大的棉花生产基地。多年来，在国家的大力支持下，新疆棉花面积、单产、总产、调出量已连续19年位居全国首位，为推动我国棉花生产和纺织工业发展做出了积极贡献。

材料二 澳大利亚常年植棉面积50万公顷，平均一个农场400公顷(6000亩)，是我国户均植棉面积的2000倍；澳大利亚棉花生产的全过程都实现了机械化；大面积种植同一个品种，采用同一个生产模式，具有很强的市场竞争力。

材料三 图甲为“新疆棉花种植区域分布图”，图乙为“澳大利亚农业区域分布图”。

图乙

    杜景俭，冀州武邑人也。少举明经，累除殿中侍御史。出为益州录事参军。时隆州司马房嗣业除益州司马，除书未到，即欲视事，又鞭笞僚吏，将以示威。景俭谓曰：“公虽受命为此州司马，而州司未受命也。何藉数日之禄，而不待九重之旨，即欲视事，不亦急耶?”嗣业益怒。景俭又曰：“公今持咫尺之制，真伪未知，即欲揽一州之权，谁敢相保?扬州之祸，非此类耶。”乃叱左右各令罢散，嗣业惭赧而止。俄有制除嗣业荆州司马，竟不如志，人吏为之语曰：“录事意，与天通，益州司马折威风。”景俭由是稍知名。入为司宾主簿，转司刑丞。

    天授中，与徐有功、来俊臣、侯思止专理制狱，时人称云：“遏徐、杜者必生，遇采、侯者必死。”累迁洛州司马。寻转凤阁侍郎、同凤阁鸾台平章事。则天尝以季秋内出梨花一枝示宰臣曰：“是何祥也?”诸宰臣曰：“陛下德及草木，故能秋木再花，虽周文德及行苇，无以过也。”景俭独曰：“谨按《洪范五行传》：‘阴阳不相夺伦，渎之即为灾。’又《春秋》云：‘冬无愆阳，夏无伏阴，春无凄风，秋无苦雨。’今已秋矣，草木黄落，而忽生此花，渎阴阳也。臣虑陛下布教施令，有亏礼典。又臣等忝为宰臣，助天理物，理而不和，臣之罪也。”于是再拜谢罪，则天曰：“卿真宰相也!”

    延载初，为凤阁侍郎周允元奏景俭党于李昭德，左迁秦州刺史。后累除司刑卿。圣历二年，复拜凤阁侍郎、同凤阁鸾台平章事。时契丹入寇，河北诸州多陷贼中。及事定，河内王武懿宗将尽论其罪。景俭以为皆是驱逼非其本心请悉原之则天竟从景俭议岁馀转秋官尚书坐漏泄禁中语左授司刑少卿出为并州长史。道病率，赠相州刺史。
