第2题
Since the molecules of a gas are much too far from each other to repel or attract each other it is very easy to compass a gas, while a solid or liquid is almost incompressible, because the repulsions of the electrical charges of which its atoms are made up are far stronger than any force we can apply. 译文：由于气体分子相隔太远，不能互相排斥或吸引，所以气体很容易压缩；而固体或液体几乎是不可压缩的，因为其原子的电荷斥力比我们所能施加的任何力都要强得多。 Based on the understanding of the above paragraph, there are four choices marked by A, B, C, D, and decide on the only one incorrect answer.
A、该句是一个复合句，其主句是it is very easy to compass a gas, while a solid or liquid is almost incompressible。
B、Because引导的原因状语从句中包含了一个定语从句，先行词是the electrical charges。
C、Because引导的原因状语从句中的定语从句先行词是repulsions。
D、在科技英语中常使用长难句，主要由于其语言特点的逻辑性强以及客观真实性。

TIRAP is an adapter molecule associated with toll-like receptors (TLRs) of the immune system, which identify pathogen-associated molecular patterns. This protein is involved in the TLR4 intracellular signaling pathway. It activates NFkB, MAPK1, MAPK3 and JNK, which then result in cytokine secretion and the inflammatory response. 附件tirap.fasta是人Homo sapiens、猕猴Macaca fascicularis、大象Loxodonta africana、马Equus caballus、鸡Gallus gallus、袋獾Sarcophilus harrisii、爪蟾Xenopus tropicalis、河豚Takifugu rubripes、剑尾鱼Xiphophorus maculatus、斑马鱼Danio rerio十个物种的TIRAP蛋白质序列。请用MEGA7为这些序列构建一株NJ树。MEGA7用ClustalW方法做出的多序列比对结果截图（1分）。参数设置页面截图：步长检验（BOOTSTRAP）取值100，其他参数默认（1分）。构建出来的Original Tree截图（1分）。构建出来的Bootstrap consensus tree截图（1分）。说出Original Tree和Bootstrap consensus tree树枝的长短有什么区别（1分）。

第10题
Today, (6)_____, the potential problem is too much carbon dioxide. Could the increase in carbon dioxide (7)_____ a global rise in average temperature, and could such a rise have serious (8)_____ for human society? Mathematical models that allow us to calculate the rise in temperature as a function of the increase (9)_____ that the (10)_____ is probably yes.
One mathematical model (11)_____ that doubling the atmospheric carbon dioxide would raise the global mean surface temperature by 2.5℃. This model assumes that the atmosphere's relative humidity remains constant and the temperature decreases with altitude at a (12)_____ of 6.5℃ per kilometer. The assumption of constant relative humidity is important, because water vapor in the atmosphere is another (13)_____ absorber or radiation at infrared wavelengths. Because warm air can hold more (14)_____ than cool air, the relative humidity will be constant (15)_____ the amount of water vapor in the atmosphere increases (16)_____ the temperature rises. (17)_____, more infrared radiation would be absorbed and reradiated (18)_____ to the Earth's surface. The resultant warming at the surface could be expected to melt snow and ice, (19)_____ the Earth's reflectivity. More solar radiation would be absorbed, (20)_____ to a further increase in temperature.
A．Whereas
B．If
C．Although
D．Because
