1. Competitors have six minutes to shear four sheep. 参赛者们有6分钟的时间来给4只羊剪毛。
2. The shear changed the quadrilateral into a parallelogram. 四边形被剪成了平行四边形。
3. To concrete shear walls, they add steel braces to a skyscraper's skeleton or beefier rebar. 为了用混凝土覆盖剪力墙,他们把钢托支撑加到摩天大楼的骨架或是大钢筋上。
4. Tthe early Pliocene had a weakened atmospheric circulation, and therefore, reduced vertical wind shear, which is favorable for tropical cyclone growth. 上新世早期的大气环流被减弱,因此垂直风切变减小,助长了热带气旋的发展。
5. To form a tornado, cold air must sit above warm and moist air, and the wind needs to go in different directions at different heights, creating shear forces. 形成龙卷风,寒冷的空气必须处在暖湿的空气上部,而风应该在不同高度向不同的方向运动,以此创造出剪切力。
