Heilongjiang province is a barn (粮仓) of China. It has rich 1 for plants to grow. The farmers sow (播撒) seeds (种子) in spring and have a harvest in 2 .
Do you know that a seed has its 3 identity card (身份证)? In our country, there is a seed 4 in Beijing. It collects all kinds of seeds from 5 places. When seeds first come in, they each get a number for 6 “physical examination”. Some workers put all kinds of seeds 7 different farms together. Then, they divide them into 8 according to the seeds’ looks. Next, workers check the seeds to 9 sure they’re healthy. A worker at the seed bank showed a seed that had a large insect 10 it. “A seed like this should not be 11 ,” he said.
After that, workers test the good ones, they use the results to predict their 12 . They dry and weigh the best seeds after several 13 . Next, they keep the seeds 14 in a fridge at -18℃. With all these done, the seeds now have their identities. It is a good 15 to protect the safety of plants. Even though there is a natural disaster on the farm, the seeds won’t die out.
1.1.
A sand
B soil
C stones
D
解析:选B。答案 B(soil) 前文提到黑龙江是粮仓,而能支撑植物生长的核心要素中,sand(沙子)和 stones(石头)均不适宜植物生长,soil(土壤)是植物生长的必要条件,符合语境。
2.2.
A seasons
B autumn
C winter
D
解析:选B。答案 B(autumn) 结合常识,农业生产中春播对应的收获季节是秋天,seasons(季节)是统称,winter(冬天)不符合春播秋收的常识,故选 B。
3.3.
A other
B half
C own
D
解析:选C。答案 C(own) 后文围绕种子库给种子设编号、做检测赋予其专属身份展开,own(自己的)能体现种子专属 “身份证” 的属性;other(其他的)、half(一半的)均与 “专属身份” 的语境不符。
4.4.
A bank
B office
C school
D
解析:选A。答案 A(bank) 后文多次出现 “the seed bank” 的指代,且结合常识及文内 “收集种子、检测保存” 的内容,可知此处指种子库;office(办公室)、school(学校)均无法承担种子收集保存的功能,故选 A。
5.5.
A same
B similar
C different
D
解析:选C。答案 C(different) 种子库的作用是收集各类种子以保护物种,若只收集 same(相同的)或 similar(相似的)地方的种子,难以实现物种保护的目的,different(不同的)符合种子库收集种子的多样性需求,故选 C。
6.6.
A its
B their
C them
D
解析:选B。答案 B(their) 此处指代前文的 “seeds”,为复数形式,空格后是名词 “physical examination”,需用形容词性物主代词。its(它的)对应单数,them(它们)是宾格形式不能修饰名词,their(它们的)符合语法和语境。
7.7.
A from
B with
C to
D
解析:选A。答案 A(from) 句子表达种子的来源地是不同农场,from 有 “来自” 的含义;with(和…… 一起)、to(到…… 去)均无法体现来源关系,故选 A。
8.8.
A groups
B lessons
C pieces
D
解析:选A。答案 A(groups) 前文提到汇总不同种子,后文 “according to the seeds’ looks” 是分类依据,divide into groups 表示 “分成小组、分类”,符合语境;lessons(课程)、pieces(碎片)与种子分类的动作无关。
9.9.
A have
B take
C make
D
解析:选C。答案 C(make) 此处考查固定搭配 “make sure”,意为 “确保”,句子表示工作人员检查种子以确保其健康;have(有)、take(拿)均无法与 sure 构成符合语境的搭配。
10.10.
A inside
B outside
C beside
D
解析:选A。答案 A(inside) 若虫子在种子 outside(外部)或 beside(旁边),对种子的损害较小,而 inside(内部)的虫子会直接破坏种子,这类种子才需被淘汰,符合后文 “不能留存” 的逻辑,故选 A。 31 题:答案 C(saved)
11.11.
A known
B broken
C saved
D
解析:选C。答案 C(saved) 带有内部虫害的种子质量不合格,没有保存价值。known(被知晓)、broken(被损坏)均不符合 “是否留存种子” 的语境,saved(被保存)契合工作人员对不合格种子的处理态度,故选 C。
12.12.
A height
B growth
C weight
D
解析:选B。答案 B(growth) 种子库检测种子是为了解其后续生长情况,height(高度)、weight(重量)仅为生长过程中的单个指标,无法全面概括检测目的;growth(生长)能涵盖种子生长的整体状态,符合检测的核心需求。
13.13.
A tests
B meets
C goals
D
解析:选A。答案 A(tests) 前文提到 “workers test the good ones”,此处承接前文,指经过数次检测后处理种子;meets(会议)、goals(目标)与种子处理流程无关,故选 A。
14.14.
A cool
B cold
C warm
D
解析:选B。答案 B(cold) 后文明确提到储存温度是 - 18℃,该温度属于低温环境。cool(凉爽的)程度不足,warm(温暖的)与低温储存需求相反,cold(寒冷的)符合该温度特征,故选 B。
15.15.
A dream
B day
C way
D
解析:选C。答案 C(way) 前文描述的种子入库流程,是保护植物安全的一种方法。dream(梦想)、day(日子)均与 “保护方式” 的语境不符,way(方式、方法)符合句子表达的逻辑,故选 C。
