干旱

A uniformly warty stocky toad of washes and streams of semiarid southwestern United States.

美国西南部半干旱地区洼地和溪流中全部是矮壮而疣皮蟾蜍。

And more marked decreases in the activity of SS occurred under drought than under waterlogging.

其中干旱处理下SS的下降比渍水更为明显。

The yield of PSⅡ of high and middle phosphor treatment was significantly higher than the control under the wettish and moderate drought conditions.

在丰水和中度干旱条件下，高磷和中磷处理的小麦各生育期的叶片PSⅡ总光化学量子产量显著高于对照处理。

Beside his heavy-shouldered team thirsty with drought and chilled with rain, he weathered all the striding years till they ran widdershins in his brain: Till the long solitary tracks etched deeper with each lurching load were populous before his eyes, and fiends and angels used this road.

他在球队的重担干旱和和口渴的雨，他饱经风霜的所有的跨年直到他们逆时针地跑在他的大脑。直到漫长的孤独的痕迹我的每一个蹒跚蚀刻负荷他的眼睛，是人口之前，和朋友和天使，用这条路。

These results can shed lights on revealing the mechanisms of plant's adaptation to xeric conditions, as well as the effects of anthropogenic disturbances on the local extinction of native species, and/or invasion of shrubs.

我们的研究结果从植物种、功能群和群落三个层次进一步揭示了植物对干旱生境的适应机制，并初步阐明了人类干扰特别是过度放牧对草原群落建群种和优势种的生态替代或/和灌丛入侵的影响。

Artemisia intramongolica is a kind of dominant shrub on sandy land in the typical grassland area o our country. It has been suitable to the hot and xeric habitat on sandy land for a long time and has formed series of characteristics that are adaptive to its habitat.

褐沙蒿是分布于我国典型草原带沙地中的优势灌木，由于长期生长在草原区沙地高温、干旱的环境中，形成了一系列与环境相适应的生物学特性。

Diverse phenological performances, xeromorphic leaf traits and different responses to drought in the savanna woody species with different leaf phenology may facilitate partitioning of resource utilization and hence co-existence of woody plants in dry-hot valley savannas.

元江干热河谷木本植物表现出来的多样性的物候特征、旱生的叶片形态结构以及不同物候类型植物的光合生理对干旱适应策略的差异有助于促进资源的合理分配和利用，促进物种共存。

Parviflora in shrub communities had the xeromorphic traits in the aspects of ① their secondary xylem had shorter vessel elements, higher vessel frequency, less single porous percentage, lower rays, higher relative conductivity and lower vulnerability index, and ② their leaf had lower water potential, lower water content and free water content, higher bound water content, high ratio of bound to free water content, and less specific leaf area.

扁担木叶片、次生木质部的解剖和水分生理特征均表现出一定的可塑性，其可塑性指数高低顺序为次生木质部解剖特征（0、24）〉水分生理特征（0.19）〉叶片解剖特征（0.18）、与侧柏林和混交林相比，灌丛中扁担木个体对干旱生境有一定的适应能力，表现在次生木质部导管分子短，导管频率高，单孔率低，木纤维短，射线矮小，具有较大的相对输导率和较小的脆性指数；叶片水势、组织含水量、自由水含量较低，叶面积、比叶面积较小，而束缚水含量、束缚水自由水比值较高。

EPHEMERAL plants are common and there may also be succulent or xerophytic perennials.

在沙漠中植物通常是短命的，也可以是肉质的或适应干旱的多年生植物。

Zenaida looked out of the window and sighed. 3. She loved playing outside or walking through the town,but not in the rain. 4. She couldn't remember the last dry day. 5. Her little brother was playing with toy cars and the baby was crying. 6. She had a stomach ifection and had been ill for two days. 7. Her mother was making dinner,and Zenaida could her the radio in the kitchen. 8. This is the twenty-sventh wet day.

Zenaida向窗外眺望，接着一声叹息 3 她喜爱在户外活动或是在巷子里走走，但不是在雨天 4 她记不得最近的一个干旱的日子是在什么时候了 5 她的弟弟在玩玩具车，宝宝在哭闹 6 她得了胃病，并且已经持续两天了 7 她的妈妈在做饭，她自己都能听见厨房里的收音机声（这句原话你打的是不是有问题？

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
