It can be inferred from the passage that, of the following, the deepest sediments*2 (最后一段) would be found in the (A) Indian Ocean (B) Black Sea*2B (C) Mid-Atlantic (D) South Atlantic ( B ) (E) Pacific 3. The author refers to a “ conveyor belt*3 ” in line 13 in order to 举例作用题(备选选项: illustrate 和 give an example of 开头的选项) (A) illustrate the effects of convection in the mantle (B) show how temperature differences depend on the positions of the continents (C) demonstrate the linear nature of the Mid-Atlantic Ridge (D) describe the complicated motions made possible by back-coupling (E) account for the rising currents under certain mid-ocean ridges 4. The author regards the traditional view*4 (大 - 小 + ) of the origin of the oceans with 态度题(混合评价的表达方法:由 but 和 and 连接的两个不同方向的评价词;由修饰词限定的评价词——本题) (A) slight apprehension 恐惧(极端) (B) absolute indifference (过于中庸) (C) indignant anger 愤慨的愤怒(人身攻击) (D) complete (程度过强) disbelief (E) guarded skepticism 5.

Which of the following, if it could be demonstrated, would most support the traditional view*6 of ocean formation? 改善题(找理论一的缺点,取非) (A) Convection usually occurs along lines*6A . (B) The upper mantle behaves as a dense solid. (C) Sedimentation occurs at a constant rate. (D) Sinking plates cool the mantle. (E) Island arcs surround enclosed seas. 7. According to the passage, the floor of the Black Sea*7 (最后一段) can best be compared to a 信息题(有定位) ACDE 无 (A) rapidly moving conveyor belt*7A (第一段) (B) slowly settling foundation ( Sediment*7B ) (C) rapidly expanding balloon (D) violently erupting volcano (E) slowly eroding mountain 8.

做科研最重要的是付出时间

看了施一公教授的的谈话,对下面的观点非常赞同:{做科研要投入,要坚持,一定可以有结果) The most important thing is what I consider to be sufficient amount of time and effort in the lab work. I mentioned that about 60 hr working time per week is what I consider the minimal time an average successful young scientist in these days has to put into the lab work……I suggest that everyone puts in at least 6 hr concentrated bench work and 2+ hr reading and other research-related activity each day. Reading papers and books should be done mostly after work.”(我认为最重要的事情就是在实验室里的工作时间,当今一个成功的年轻科学家平均每周要有60小时左右的时间投入到实验室的研究工作......我建议每个人每天至少有6小时的紧张实验操作和两小时以上的与科研直接有关的阅读等。文献和书籍的阅读应该在这些工作时间之外进行。)。

Higgs消息13日公布(上帝不会来)
热度 1 yushi 2011-12-5 17:22
CERN的内部邮件: Dear colleagues, I would like to invite you to a seminar in the main auditorium on 13 December at 14:00, at which the ATLAS and CMS experiments will present the status of their searches for the Standard Model Higgs boson. These results will be based on the analysis of considerably more data than those presented at the Summer conferences, sufficient to make significant progress in the search for the Higgs boson, but not enough to make any conclusive statement on the existence or non-existence of the Higgs. The seminar will also be webcast.

it would be sufficient to really understand the electron.

把一件事情搞复杂很容易,要把一堆事情简化很难 当今科学的局面是,无数人在一起努力把事情搞复杂,没人去搞懂最基本的概念。 所以,今天的科学,越来越难懂了
