阅读以下短文，回答下列题：

由我国科学家精确绘制的水稻第四号染色体精确测序图发表在代表国际权威的英国《自然》杂志上。科技部：中国科学院在上海宣布，我国科学家独立完成了“国际水稻基因组计划”第四号染色体精确测序任务，对这一国际计划的贡献率达10%，这是我国迄今为止完成的最大基因单条染色体的精确测序。
刊于《自然》杂志的论文《水稻基因组第四号染色体序列及分析》宣布，中国科学家采用克隆步移法完成了对水稻粳稻基因组第四号染色体全长序列的精确测定。拼接后总长为3500万碱基对，精确度为99.99%，覆盖了染色体全长序列98%的区域，达到国际公认的基因组测序图的标准。
科学家们在完成序列精确测定的同时，还做了大量的研究工作：对水稻第四号染色体所含基因进行预测分析，鉴定出4658个基因，为进一步鉴定这些基因的功能奠定了基础；完整地测定了水稻四号染色体的着丝粒序列，这是迄今首次完成的高等生物染色体着丝粒序列，为研究着丝粒的功能、染色体的稳定性和染色体的复制提供了基础，也为开发可转化的“人工水稻或植物染色体”提供了基础。以蓝天、白云、金色水稻为封面的本期《自然》杂志，同时也刊登了日本科学家对水稻第一号染色体的精确测序。
测序专家工作组组长、中科院国家基因研究中心的韩斌博士告诉记者，第四号染色体的测序工作于2001年4月启动，首先完成精细物理图，然后采用克隆步移法大规模测序，绘制基因组完成图。此外，研究人员还对另一个亚种籼稻品种广陆矮第四号染色体的序列也进行了测定，报道了水稻两个主要栽培稻在基因组成、顺序及DNA序列水平上的一些异同，揭示两者之间的一些亲缘和进化关系，这些数据为将来整个基因水平的比较提供了良好的示范。
韩斌博士还表示，目前世界上有一半以上的人口以水稻为主食。水稻基因组第四号染色体的序列分析结果和今后的功能基因组研究，可获得大量的水稻遗传信息和功能基因，为培育优良性状的水稻新品种打下良好的基础。同时此次测序成果，还将有助于了解小麦、玉米等其他重要粮食作物的遗传秘密，从而推动整个农作物基因组的研究。

根据文章内容，下列推断不正确的一项是( )。

A．“国际水稻基因组计划”是一项国际合作开发的计划，除中国科学家参加外，许多外国科学家也参与了这一计划，中国只是承担了这一计划中的部分任务
B．“国际水稻基因组计划”的完成可以部分地揭示小麦、玉米等其他重要粮食作物的遗传秘密
C．水稻基因组第四号染色体的测序成果，可为培育优良性状的水稻新品种打下良好的基础
D．研究人员对广陆矮第四号染色体的序列也进行了测定，所得数据为将来整个基因水平的比较提供了良好的示范

We have all experienced days when everything goes wrong. A day may begin well enough, but suddenly everything seems to get out of control. Sometimes a single unimportant event may cause a number of things to happen. Let us suppose that you are preparing a meal and keeping an eye on the baby at the same time. The telephone rings and this causes your troubles to begin. While you are on the phone, the baby pulls the tablecloth off the table, destroying your half-prepared meal. You hang up hurriedly and attend to your baby. Meanwhile, the meal gets burnt. As if this is not enough to bring you to tears, your husband arrives home, unexpectedly bringing three guests to dinner.

Things can also go wrong on the road. During rush hour one evening two cars collided and the drivers began to argue. The woman driver behind the two cars happened to be a learner. She got into a panic and stopped her car. This forced the driver following her to stop suddenly. This driver’s wife was sitting beside him holding a large cake, and as she was thrown forward, the cake went right through the window and landed on the road. A truck driver seeing a cake flying through the air slammed on the brakes. The truck was carrying empty beer bottles and hundreds of them slid off the back of the truck onto the road, causing a terrible traffic jam. It took the police an hour to get the traffic on the move again. In the meantime, the truck driver had to sweep up hundreds of broken bottles. Only two dogs were enjoying themselves, for they were happily having what was left of the cake.
