一.   Literacy and the Vernacular In Late Medieval Europe

一開始說辦學(xué)校只有有錢人家的男孩子能上，F(xiàn)地方600個學(xué)生上一個教Latin的學(xué)校目的是要讓他們以clergy和lawyer為career,還有—個學(xué)校人更多是以artisan和businessman為career的教accounting和方言，后來傳播開來了，會read and write的人也有一點了，人們開始會記錄家里的收入和生活，還不會read和write的人也能聽別人講而懂一些消息，然后農(nóng)民和城里人在一年的節(jié)日都會put aside work幵始一些祭祀活動drama, play之類的，還有translation—些圣經(jīng)之類的從Latin到別的語言，女人在encourage translation中也有作用，然后她們這樣是為她們要guide their children,文章最后又critical地講了一下不用會read和write也可以懂知識，舉了2個人的例子。

二.   Differences of Biodiversity in geographical patterns

赤道地區(qū)和溫帶地區(qū)物種的多樣性是不同的，熱帶地區(qū)物種多樣性要比溫帶好很多，然后舉了很多物種的例子;有很多理論提出來解釋這個現(xiàn)象。第一個理論是：熱帶地區(qū)接受的光照和降水要比溫帶地區(qū)多很多，意味著reproduce material 也要多很多，有助于植物的reproduce， reproductive的速度也好高很多，有利于多種生物的生存，但是溫帶地區(qū)就要少很多。舉了很多例子。第二個理論是：熱帶地區(qū)氣候比較穩(wěn)定;有利于多種多樣動植物的進化和發(fā)展在一個比較持續(xù)穩(wěn)定的環(huán)境中進行，沒有干擾和中斷;但是溫帶地區(qū)氣候季節(jié)變化比較大，很多生物要存活下來要能夠忍受極端的寒冷，還舉了間冰期的例子。所以物種的存活和進化需要很長的時間。熱帶地區(qū)比溫帶地區(qū)持續(xù)的區(qū)間范圍大。熱帶地區(qū)是沿著赤道向南北延伸，是一個整塊的連續(xù)的地理范圍，但是溫帶地區(qū)是分別分散在北半球和南半球的。同時因為熱帶地區(qū)溫度較高，所以parasite 比較多，這樣就不利于同一種單一植物大范圍的生長，擴大了同種植物的地理間隔;而溫帶地區(qū)因為冬季會殺死一部分植物，所以很多植物是單一物種集中生長的。 熱帶地區(qū)任何一個canopy都可能是一個community, 環(huán)境適合多種生物生長，但是溫帶地區(qū)則不然。

三.   Eli Terry’s Clock

十九世紀初，鐘表在美國是非常奢侈的產(chǎn)品，只有有錢人才能用得起。一個鐘匠一年只能生產(chǎn) 10 到 15 只鐘表，特別煞費苦心(painstaking)。后來一個叫 Eli Terry 的人進行了一系列的變革，通過簡化制造材料，創(chuàng)新設(shè)備，改善水力等，讓表的產(chǎn)量變得又大、又輕、價格又便宜。原來特別重，不好運輸，改善得更輕后，可以掛住，不用專門做 cabinet, 并且中產(chǎn)階級也能買得起了。從原來的低產(chǎn)量變成了高產(chǎn)(mass production)。后來在他持續(xù)的發(fā)明創(chuàng)造中，他在 1816 年造出了 shelf clock, 獲得專利，導(dǎo)致很多人開始模仿他，同時也促進了鐘表的精細化。最后一段提到了另一個人，和他一起把鐘表變得物美價廉。

Animal Behavior

By the early 1900s the field of animal behavior had split into two major branches. One branch, ethology, developed primarily in Europe. To ethologists, what is striking about animal behaviors in that they are fixed and seemingly unchangeable? For example, kittens and puppies play in characteristic but different ways. Present a kitten with a ball of yarn and invariably it draws back its head and bats the yarn with claws extended. Kittens are generally silent as they play, and their tails twitch. Puppies, by contrast, are most likely to pounce flat-footed on a ball of yarn. They bit and bark and their tails wag. Ethologists came to believe that ultimately even the most complex animal behaviors could be broken down into a series of unchanged able stimulus/response reactions. They became convinced that the details of these patterns were as distinctive of a particular group of animals as were anatomical characteristics. For well over half a century, their search for and description of innate patterns of animal behavior continued.

Meanwhile, mainly in North America, the study of animal behavior took a different tack, developing into comparative behavior. Of interest to comparative behaviorists was where a particular came from, that is, its evolutionary history, how the nervous system controlled it, and the extent to which it could be modified. In 1894, C. Lloyd Morgan, an early comparative behaviorist, insisted that animal behavior be explained as simply as possible without reference to emotions or motivations since these could not be observed or measured. In Morgan’s research, animals were put in simple situations, presented with an easily described stimulus, and their resultant behavior described.

The extension to animals of behaviorism—the idea that the study of behave or should be restricted to only those elements that can be directly observed—was an important development in comparative behavior. Studies of stimulus/response and the importance of simple rewards to enforce and modify animal behavior were stressed. Not surprisingly, comparative behaviorists worked most comfortably in the laboratory. Comparative behaviorists stressed the idea that animal behavior could be modified, while their ethologist colleagues thought it was innate and unchangeable. Inevitably, the two approaches led to major disagreements.

To early ethologists, the major driving force in behavior was instinct, behaviors that are inherited and unchangeable. Moths move towards light because they inherit the mechanism to so respond to light. Although dogs have more options available to them, they bark at strangers for much the same reasons. The comparative behaviorists disagreed: learning and rewards are more important factors than instinct in animal behavior. Geese are not born with the ability to retrieve lost eggs when they roll out the nest, they learn to do so. If their behavior seems sometimes silly to humans because it fails to take new conditions into account, that is because the animal’s ability to learn is limited. There were too many examples of behaviors modified by experience for comparative behaviorists to put their faith in instincts.

The arguments came to a peak in the 1950s and became known as the nature or nurture controversy.

Consider how differently an ethologist and a comparative behaviorist would interpret the begging behavior of a hatchling bird. The first time a hatchling bird is approached by its parent, it begs for food. All baby birds of a particular species beg in exactly the same way. Obviously, said the ethologists, they inherited the ability and the tendency to beg. Baby birds did not have to learn the behavior, they were born with it—a clear example of innate, unchanging behavior. Not so, countered the comparative behaviorists. Parent birds teach their young to beg by stuffing food in their open mouths. Later experiments showed that before hatching, birds make and respond to noises of their nest mates and adults. Is it not possible that young birds could learn to beg prenatally?

It was hard for ethologists to accept that innate behaviors could be modified by learning. It was equally difficult for comparative behaviorists to accept that genetic factors could dominate learning experiences. The controversy raged for over a decade. Eventually,  however, the distinctions between the two fields narrowed. The current view is that both natural endowments and environmental factors work together to shape behavior.

Wind pollination

Pollen, a powdery substance, which is produced by flowering plants and contains male reproductive cells, is usually carried from plant to plant by insects or birds, but some plants rely on the wind to carry their pollen. Wind pollination is often seen as being primitive and wasteful in costly pollen and yet it is surprisingly common, especially in higher latitudes. Wind is very good at moving pollen a long way; pollen can be blown for hundreds of kilometers, and only birds can get pollen anywhere near as far. The drawback is that wind is obviously unspecific as to where it takes the pollen. It is like trying to get a letter to a friend at the other end of the village by climbing onto the roof and throwing an armful of letters into the air and hoping that one will end up in the friend’s garden. For the relatively few dominant tree species that make up temperate forests, where there are many individuals of the same species within pollen range, this is quite a safe gamble. If a number of people in the village were throwing letters off roofs, your friend would be bound to get one. By contrast, in the tropics, where each tree species has few, widely scattered individuals, the chance of wind blowing pollen to another individual is sufficiently slim that animals are a safer bet as transporters of pollen. Even tall trees in the tropics are usually not wind pollinated despite being in windy conditions. In a similar way, trees in temperate forests that are insect pollinated tend to grow as solitary, widely spread individuals.

Since wind-pollinated flowers have no need to attract insects or other animals, they have dispensed with bright petals, nectar, and scent. These are at best a waste and at worst an impediment to the transfer of pollen in the air. The result is insignificant-looking flowers and catkins (dense cylindrical clusters of small, petalless flowers).

Wind pollination does, of course, require a lot of pollen. Birch and hazel trees can produce5.5 and 4 million grains per catkin, respectively. There are various adaptations to help as much of the pollen go as far as possible. Most deciduous wind-pollinated trees (which shed their leaves every fall) produce their pollen in the spring while the branches are bare of leaves to reduce the surrounding surfaces that “compete” with the stigmas (the part of the flower that receives the pollen) for pollen. Evergreen conifers, which do not shed their leaves, have less to gain from spring flowering, and, indeed, some flower in the autumn or winter.

Pollen produced higher in the top branches is likely to go farther, it is windier (and gustier) and the pollen can be blown farther before hitting the ground. Moreover, dangling catkins like hazel hold the pollen in until the wind is strong enough to ben them, ensuring that pollen is only shed into the air when the wind is blowing hard. Weather is also important. Pollen is shed primarily when the air is dry to prevent too much sticking to wet surfaces or being knocked out of the air by rain. Despite these adaptations, much of the pollen fails to leave the top branches, and only between 0.5 percent and 40 percent gets more than 100 meters away from the parent. But once this far, significant quantities can go a kilometer or more. Indeed, pollen can travel many thousands of kilometers at high altitudes. Since all this pollen is floating around in the air, it is no wonder that wind-pollinated trees are a major source of allergies.

Once the pollen has been snatched by the wind, but not everything is left to chance. Windborne pollen is dry, rounded, smooth, and generally smaller than that of insect-pollinated plants. But size is a two-edged sword. Small grains may be blown farther but they are also more prone to be whisked past the waiting stigma because smaller particles tend to stay trapped in the fast-moving air that flows around the stigma. But stigmas create turbulence, which slows the air speed around them and may help pollen stick to them.

B. Animals serve as pollinators even where there is little wind to disperse the pollen.

C. An animal that visits a flower is likely to deliberately visit other flowers of the same species and pollinate them.

D. Birds and insects fly in all directions, not just the direction the wind is blowing at a given moment.

5. In paragraph 1, the author compares pollen moved by wind with letters thrown off roofs in order to

A. Because there are few trees in temperate forests, it is safer to transport pollen by insects or birds.

B. Wind pollination is a safe reproductive strategy for trees in temperate forests where there are only a few dominant species and, therefore, many individuals of the same species.

C. Wind pollination requires production of large amount of pollen, which must be released at the right time and under the right conditions to extend its range.

D. Most wind-pollinated trees are deciduous because evergreen needles compete with the stigma for pollen, making wind pollination uncertain.

E. Wind-pollinated plants usually have small petalless flowers which often grow in catkins that produce a very fine-grained pollen.

F. Wind-pollinated trees must grow in regions that are only moderately windy because strong winds will blow the tiny pollen grains past the stigma.
