Kammerer showed that both forms of Salamandra can be induced to lay their eggs early or late, according to the physical conditions surrounding them. If they are kept in water or in proximity to water and in a moist atmosphere they have a tendency to lay their eggs earlier and a comparatively high temperature enhances the tendency to shorten the period of gestation. If the salamanders are kept in comparative dryness they show a tendency to lay their eggs rather late and a low temperature enhances this tendency.英文原著 · 《Darwin and Modern Science》
Still my flight was in a parabola; and, in a period not longer than it has taken to describe it, I was thrown senseless, at last, into a deep snow-bank near the United States Arsenal. Tender hands lifted me and assuaged me. Tender teams carried me to the City Hospital. Tender eyes brooded over me. Tender science cared for me. It proved necessary, before I recovered, to amputate my two legs at the hips. My right arm was wholly removed, by a delicate and curious operation, from the socket. We saved the stump of my left arm, which was amputated just below the shoulder.英文原著 · 《The Brick Moon》
With most tendril-bearers the summit of the stem or shoot projects above the point from which the tendril arises; and it is generally bent to one side, so as to be out of the way of the revolutions swept by the tendril. In those plants in which the terminal shoot is not sufficiently out of the way, as we have seen with the Echinocystis, as soon as the tendril comes in its revolving course to this point, it stiffens and straightens itself, and thus rising vertically up passes over the obstacle in an admirable manner.英文原著 · 《The Movements and Habits of Climbing Plants》
As she is not so extremely young, the choice of her lovers cannot be entirely at her option. I promise you, she will not refuse the tender of your most humble services. Distinguish her, then, by attentions and by tender looks. Take favorable opportunities of whispering that you wish esteem and friendship were the only motives of your regard for her; but that it derives from sentiments of a much more tender nature: that you made not this declaration without pain; but that the concealing your passion was a still greater torment.英文原著 · 《Letters to His Son, 1751》
The Tenderfoot, by the irony of fate, drew a tenderfoot horse. Tunemah was a big fool gray that was constitutionally rattle-brained. He meant well enough, but he didn't know anything. When he came to a bad place in the trail, he took one good look--and rushed it. Constantly we expected him to come to grief. It wore on the Tenderfoot's nerves. Tunemah was always trying to wander off the trail, trying fool routes of his own invention. If he were sent ahead to set the pace, he lagged and loitered and constantly looked back, worried lest he get too far in advance and so lose the bunch.英文原著 · 《The Mountains》
An open space is thus left for the next succeeding and younger tendril to stand vertically upwards and to revolve freely. As soon as an old tendril bends downwards, it loses all power of movement, and contracts spirally into an entangled mass. Although the tendrils revolve with unusual rapidity, the movement lasts for only a short time. In a plant placed in the hot- house and growing vigorously, a tendril revolved for not longer than 36 hours, counting from the period when it first became sensitive; but during this period it probably made at least 27 revolutions.英文原著 · 《The Movements and Habits of Climbing Plants》
