issue发行,发布:(报刊杂志的)一期

I needed 8 more courses at the intermediate level or higher in the last 2 years to be OK.我在最后

两年里需要再修8门中等或中等以上的课程。

it could be that I have taken 2 basic courses but coupled both of them with field experiences. 可能

是我选修的两门基础课,但是这两个都有相应的实地研究。

couple。。with 与。。相结合;伴随

I could only take intro courses because there were no intermediate level courses available for

those particular topics. 因为这些课题没有对应的中级课程可选,所以我只能选入门课。

some of my classmates, did this for an easy way to meet their intermediate course requirement, but

I did it to get the kind of depth in those topics I was going for. 我的一些同学这么做是为了这比

较容易完成中级课程((credits)的要求,但是我是为了对所学的课题有比较深入的了解。

As it turned out I really enjoyed the field work,it was a nice supplement to just sitting and

Lecture 1

Animal behavior 动物行为

passive habitat selection被动的栖息地选择

make active choices 主动做出选择

they are dispersed by some other agent, like the wind. 他们由其他媒介,如风所传播。

agent媒介,中介

if the seeds land in a suitable habitat, they do well and reproduce. 他们如果落到一个适宜的环

境,他们能长得不错并且繁殖。

with active habitat selection, an organism is able to physically select where to live and breed. 主

动选择栖息地的生物能够选择自身在何处生长和繁殖。

breeding habitat 繁衍栖息的场所

preference for particular types of habitats 对特定类型栖息地的优先考虑

so look at the effect this preference can have by looking at some examples. 通过几个例子来看选

择栖息地的倾向可能会产生的结果/影响。

effect 影响;效果

let's recap 扼要回顾一下。

there are some key elements that a habitat must contain, food obviously, water, it's got to have the

right climate and spaces for physical protection. 栖息地必须包括一些关键的因素:食物,水,

还必须具有适宜的气候和自我保护的空间。

and we saw how important habitat selection is when we look at habitats where some of these

factors are removed, perhaps through habitats' destruction. 我们知道栖息地的选择很重要。有的

栖息地受到破坏,一些重要的有利于生物生存的条件随之也没有了。

shorebird 岸禽类鸟

the plover lives by the ocean and feeds on small shellfish, insects and plants. plover 生活在海边,

吃小的甲克类水生动物,昆虫和植物。

it blends in with the sand, so it's well-camouflaged from predators birds above. 它与沙滩混为一

体,这是很好的掩护。他们能躲避上空盘旋的掠夺性的鸟类。

it lays its eggs in shallow depressions in the sand with very protection around them. 它们在沙坑

里下蛋,这些蛋四周没有什么防护物体。

so if there are people or dogs on the beach, the eggs and fledglings in the nests are really

vulnerable. 如果人或者狗在沙滩上,窝里的蛋和幼鸟,就相当危险。

out in the California where there has been a lot of human development by the ocean. 在加利福尼

亚,海洋边上,有很多的人工建筑。

the plovers are now a threatened species. the plovers现在是濒危物种了。

so conservationists tried to recreate a new habitat for them. 所以很多动物保护主义者尝试为他

们重建一个栖息地。

they made artificial beaches and sand bars in areas inaccessible to people and dogs. 他们在人和

狗到不了的地方修造人工沙滩和沙洲。

and the plover population is up quite a bit in those places. 在这些地方,plover 鸟的数量增加了

不少。

that's an instance where a habitat is made less suitable. 那是一个不太适宜的栖息地。

what about cases where an animal exhibits a clear choice between two suitable habitats?

exhibit a clear choice between ..在,,之间表现出明显的选择。

in cases like that, does the preference matter? 在那样的情况下,倾向性重要吗?

blue warbler 蓝莺

The Blue warbler is a songbird that lives in North America. 蓝莺是北美的一种鸣鸟。

they clearly prefer hard wood forests with dense shrubs, bushes underneath the trees. 他们明显倾

向于有着稠密的灌木丛的硬木森林。

they actually nest in the shrubs, not the trees. 他们在灌木丛中筑巢。

but these warblers also nest in forests that have low shrub density. 但是蓝莺也在灌木丛稀疏的

森林里筑巢。

it is usually the younger warblers that nest in these areas because the preferred spots where there

are a lot of shrubs are taken by the older, more dominant birds. 通常是较为年轻的蓝莺在这些

地方筑巢,因为更好的地方已经被占主导地位的成年鸟占领。which suggests that the choice of

where to nest does have an impact on the number of chicks they have. 在哪里筑巢确实会影响到

能繁殖多少只雏鸟。

but a preferred environment doesn't always seem to correlate with greater reproductive success.但

是首选的环境并不总是意味着高的繁殖率。

studies have been done on the reproductive success rates for the birds in both areas, and the result

showed surprisingly that the reproductive success was essentially the same in both areas.

which lower the suitability of the prime habitat even though it's their preferred habitat. 那会降低

主栖息地的适合性。

it looks like competition for resources is another important factor in determining if a particular

habitat is suitable. 争夺资源也是判断一个栖息地是否合适的重要因素。

Lecture 2

art history 艺术历史

there were, our book mentions, classes for women artists. 我们书上提到,有为女学生开设的课

程。

take private lessons 上私教课

so within a few decades, things had changed significantly. 在几十年内,情况发生了很大的变

化。

a private art academy opened in Paris. 在巴黎开办一家私人艺术学院。

for decades it was probably the most famous private art school in the world. 在长达几十年的过

程中,这所学校可能是世界上最有名的。

he completely separated the men and women students. 他将男女学生完全分开。

Julian was a brilliant man, with progressive ideas. Julian是个非常聪明的生意人,他具有超前的

想法。

he saw that another small private art school where all the students were women was very popular

at that time. 他当时看到,一个全是女学生的学校会很受欢迎。

and that's probably why he adopted the women only classes. 那大概是为什么他采用专门对女

学生开放的班级吧。

this was a big deal because finally women could study art in a formal setting. 这是很大的进步,

因为女性终于可以正式在教室学习艺术了。

and there was another benefit to the group sitting of these classes. 这些班级的集体性学习模式

也有另一个好处。

the classes included weekly criticism. 这些班级会进行每周一次的测评。

and the teacher would rank the art of all the students in the class from best to worst. 老师会全班

学生的作品排名,从最好排到最差。

and it gave her an incentive to do better. 这激励她自己要做得更好。

a conversation between a student and a business professor 经济学/商业学 教授

gym 健身房

health club; fitness center

health-club model 健身房商业模式

I was talking about an issue in strategic marketing, the healthy club model. 健身房商业模式的营

销策略上的一个问题。

I know when I pass by a health club, and I see all those people working out, they're exercising, I

just as soon walk on by. 当我经过健身房的时候,我看到很多人在健身,但我不会驻足。

there is that. 就是你说的那个问题。

plus, lots of people have exercises equipment at home or they can play sports with their friends.

另外,很多人家里有健身器材。或者他们可以和朋友一起做运动。

but nowadays, in spite of all that, and expensive membership fees, health clubs are hugely popular,

so how come? 但是现在,除了上面说的那些,健身房的会员费也很贵,但是健身房现在却

特别流行。这是怎么回事?

it's not as unusual as it sounds. 并不是像听起来那么的罕见。

timeline (尤指历史事件) 年表

let's tie this to what I've said before about societal attitudes towards glasses. 现在将这个与前面

讲到的人们对眼镜的看法联系起来。

this is evident in the artwork from the period. 从当时的文学绘画作品来看,这一点是很明显

的。

European paintings often portrayed doctors or judges wearing glasses. 欧洲的画作中,医生或法

官通常是带着眼镜的。

so in addition to intelligence, they also symbolize affuence, wealth. 所以,除了代表智慧,眼镜

也象征着富裕,或财富。

In 14th-century Chinese portraits, the bigger the glasses, the smarter and wealthier the subject was.

14世纪,中国的画像中,戴的眼镜越大,表明这个人越富有和聪明。

so glasses were a status symbol in some parts of the world. 在世界上一些地区,眼镜是一种地位

inexpensive便宜的

people could purchase them easily from a traveling peddler. 人们可以很容易就从小贩那里买到

眼镜。

Lecture 4

chemistry化学

the periodic table of elements 元素周期表

predictive预测性,预言性

prediction预测

it groups elements into categories that share certain properties.

元素周期表将具有相同属性的元素分作一类。

it is arranged according to increasing atomic number. 按原子数递增的顺序排列。

the number of protons in each atom of an element. 元素原子中的质子数。

early versions of the periodic table had gaps, missing element. 早期版本的元素周期表中有空

缺,丢失的元素。

every time you had one more proton, you had another element. 每发现一个质子数,你会得到

一种新的元素。

there'd be an atomic number, for which there was no known element.

有时候,得到了一个原子数,却不知道对应的元素是什么。

and the prediction was that an element, with that atomic number existed somewhere, but it just

hadn't been found yet. 在原子数确定,元素未知的情况下,可以通过元素周期表的预测性来。。

and its location in the table would tell you what properties it should have. 它在表中位置可以告

诉我们这个元素有什么特性。

it was really pretty exciting for scientists at that time to find these missing elements and confirm

their predictive properties. 对当时的科学家来说,找到缺失的元素并确认他们预定的特质是

很令人激动的事。

that reminds of a very good example of all these, 这让我想起一个很好的例子。

symbol of elements 元素符号

and then in 1925, a team of chemists led by a scientist named Ida Tacke claimed that they had

found element 43. 然后在1925年,由一名叫Ida Tacke科学家带领的化学家团队声称他们找

到了43号元素。

they had been using a relatively new technology called X-ray spectroscopy, 他们当时使用了一

种相对较新的技术 x射线光谱学and they were using this to examine an ore sample.他们用x

射线光谱学来检验矿石样本。

let me add that. 让我补充说明一下。

and they were never able to isolate enough Masurium to have a weighable sample to convince

everyone of the discovery. 他们一直没有分离出足够的Masurium作为样本,来说服人们相信

他们的发现。

so they were discredited. 所以他们遭到了人们的质疑。

A different team became the first to synthesize an element using a cyclotron(粒子回旋加速器).

另一个团队使用粒子回旋加速器合成了最早的一种(质子数为43)的元素。

and they named it Technetium to emphasize that it was artificially created with technology. 命名

为Technetium 是为了强调,它是通过技术人工合成的。

and people thought that synthesizing this, element making it artificially was the only way to get it.

人们认为人工合成是得到这种元素的唯一方法。

radioactive放射性的

it dacays, it turns into other elements. 这种元素会衰变,会转化为其他的元素。

because of its radioactive decay, element 43 doesn't last very long. 因为43号元素的放射性衰

变,它不能长久存在。

and therefore, if that ever had been present on Earth, it would have decayed ages ago. 所以,如果

它曾经在地球上存在过,也早就衰变了。

it can be naturally generated from Uranium atoms that have spontaneously split. 它可以从

Uranium原子自发的裂变中自然产生。

the ore sample the Masurium group was working with had plenty of Uranium in it enough to split

into measurable amounts of Masurium.

Masurium团队研究的矿石样本含有大量的Uranium,足够分裂出可量的Masurium。

so Tacke's team might very well have found small amounts of Masurium in the ore sample. 所以

Tacke's team可能真的在矿石样品中找到了小量的Masurium。

it's just that once was generated from split Uranium, it decayed very quickly. 只是Masurium一从

Uranium裂变中产生就衰变了。

here is an incredible irony, Ida Tacke, she was the first to suggest that Uranium could break up

into smaller pieces, but she didn't know that was the defense of her own discovery of element 43.

颇具有讽刺意味的是,Ida Tacke是最早提出Uranium 可以分裂成小片,但她不知道它可以

以此来辨明自己确实发现了43号元素。

they didn't publish enough detail or their methods or instruments for us to know for sure. 他们没

有发表关于他们使用的方法,或仪器的足够多的详细信息使我们能确切知道。

spontaneous fission自发裂变

Nuclear fission is the splitting of the nucleus of an atom to produce a large amount of energy or

cause a large explosion. 核裂变
