[托福閱讀]tpo30-3-1,Role of Play in Development

Play is easier to define with examples than with concepts. In any case, in animals it consists of leaping, running, climbing, throwing, wrestling, and other movements, either alone, with objects, or with other animals. Depending on the species, play may be primarily for social interaction, exercise, or exploration. One of the problems in providing a clear definition of play is that it involves the same behaviors that take place in other circumstances – dominance, predation, competition, and real fighting. Thus, whether play occurs or not depends on the intention of the animal, and intentions are not always clear from behavior alone.

According to paragraph 1, why is play difficult to define?

A. Play must be defined with concepts, not examples.

B. Play behavior often looks like nonplay behavior.

C. Play often occurs in the presence of animals that are not playing.

D. Play occurs independently of an animal’s intentions.

[托福阅读] tpo30-1-4 细节题

A heated debate has enlivened recent studies of evolution. Darwin's original thesis, and the viewpoint supported by evolutionary gradualists, is that species change continuously but slowly and in small increments. Such changes are all but invisible over the short time scale of modern observations, and, it is argued, they are usually obscured by innumerable gaps in the imperfect fossil record. Gradualism, with its stress on the slow pace of change, is a comforting position, repeated over and over again in generations of textbooks. By the early twentieth century, the question about the rate of evolution had been answered in favor of gradualism to most biologists' satisfaction.

Sometimes a closed question must be reopened as new evidence or new arguments based on old evidence come to light. In 1972 paleontologists Stephen Jay Gould and Niles Eldredge challenged conventional wisdom with an opposing viewpoint, the punctuated equilibrium hypothesis, which posits that species give rise to new species in relatively sudden bursts, without a lengthy transition period. These episodes of rapid evolution are separated by relatively long static spans during which a species may hardly change at all.

Question 4 of 13

According to paragraphs 1 and 2, the punctuated equilibrium hypothesis and the gradualism hypothesis differed about

A. whether the fossil record is complete

B. whether all species undergo change

C. whether evolution proceeds at a constant rate

D. how many new species occur over long periods of time

2.与渐进主义相反的假设——突然的进化——species in relatively sudden bursts, without a lengthy transition period

[托福-阅读] The Pace of Evolutionary Change tpo30-1-11

The question about the rate of evolution must now be turned around: does evolution ever proceed gradually, or does it always occur in short bursts? Detailed field studies of thick rock formations containing fossils provide the best potential tests of the competing theories.

Occasionally, a sequence of fossil-rich layers of rock permits a comprehensive look at one type of organism over a long period of time. For example, Peter Sheldon's studies of trilobites, a now extinct marine animal with a segmented body, offer a detailed glimpse into three million years of evolution in one marine environment. In that study, each of eight different trilobite species was observed to undergo a gradual change in the number of segments-typically an increase of one or two segments over the whole time interval. No significant discontinuities were observed, leading Sheldon to conclude that environmental conditions were quite stable during the period he examined.

Question 11 of 13

The main purpose of paragraph 7 is to

A. describe one test of the competing theories

B. provide an example of punctuated equilibrium

C. describe how segmented animals evidence both competing theories

D. explain why trilobites became extinct

告訴大家個小技巧，他問這段的目的除了可以看完整段外，可以先去上一段結尾看，因為段落間都會有點小關聯，否則就是一篇不好的文章，所以依此往上段最後一句話看"Detailed field studies of thick rock formations containing fossils provide the best potential tests of the competing theories."
所以我們得知他下一段必會介紹一個test，就是問題要我們看的那段，答案自然是a

2019 - v2ray 正確 快速安全的上網配置

1. 配置方面
很多人都愛套v2ray的 tls cdn 甚麼加密甚麼的 看網路上教學一堆亂教的

加這麼多有的沒得特徵超級明顯的

目前tcp & kcp 都很容易被封搭!

正確的v2ray 配置是 websocket + without tls

port : 433, 8080, etc 等常見低port number (你他媽別老是用一堆高port)


2. GCP節點的選取

可以選香港節點, 你選到的ip是很重要的

推薦可以選的區域有
asia-east1 a、b、c 台灣彰化縣
asia-east2 a、b、c 香港
asia-northeast1 a、b、c 日本東京

其中 c 區是相對好的, c 區 通常配置較低, 較少人用
翻牆哪需要甚麼很強的配置. 另外, 多嘗試或許一些ip去測速看哪個好
ip段也是影響速度的重大因素阿
