Scientists think that dinosaurs existed on Earth for almost 200 million years. 19 could these great beasts, some of which weighed thousands of pounds and stood 100 feet tall, suddenly disappear? 11 The most popular theory is that the dinosaurs were killed off when an asteroid into southern Mexico. The asteroid's collision caused earthquakes, fires, and tidal waves. Volcanoes erupted, spewing poisonous gases into the sky and lowering the oxygen level in the oceans. Plants died, removing the food source for plant-eating dinosaurs. As these dinosaurs died, there was no food for meat-eating dinosaurs. In a short period of time, the dinosaurs were gone, and the first mammals began to appear. Many scientists note that, 21 the asteroid had a major impact, the Earth's climate had already scientists claim that mammals already on Earth before the asteroid might have 22 the extinction begun to change. The planet was cooling, and the colder temperatures were likely killing plants. Some by eating dinosaur eggs. We may never know for certain what caused the extinction of the dinosaurs. But it was most likely the result of a combination of the asteroid, colder climates, and egg-stealing mammals 23 the single event of the asteroid hitting the Earth. 2024年度 全学 Casey Malarcher et al., Reading for the Real World 1, Second edition When ② 19 What 3 Who 4 How came ② carried 20 3 crashed 4 burst 21 while once 3 unless 4 yet 22 ① governed obstructed 3 facilitated 4 united 23 1 other than rather than ③ except for 4 owing to

y II Day 12 15 5 Negro Leagues Baseball was a collection of major and minor-league baseball leagues that were the first to showcase black team sports on intertwined with the African American and American experience not only a national scale. Launched in 1895, the leagues, as with jazz, became as a cultural element, but as a lucrative business endeavor. team The leagues were not under central management, and schedules and composition League, were changeable from season to season. Appearance and disappearance of leagues was common: the National Colored Baseball for instance, collapsed after only two weeks of operations. Latins, especially Cubans, were also a significant presence on teams. In these ways, the Negro Leagues were quite similar to their white counterparts which would eventually consolidate into Major League Baseball. Blacks near the beginning of the 20th century had only a fraction of whites' purchasing power, so the emergence of the Negro Leagues might have seemed unlikely. However, the Negro Leagues had two main draws that accounted for its business success. The first was a deep reserve of athletic talent. After blacks were formally excluded from white leagues in the 1880s, the Negro Leagues were the sole organization through which black players could work professionally. The quality of Negro Leagues 20 players was high, and substantiated through exhibition matches between Negro Leagues and Major League teams: over the years, both had their fair share of wins and losses in these matches. Another reason for the success of the Negro Leagues was an increasingly affluent black fan base. Driven by American industrialization, blacks were concentrating in major cities such as New York City, Chicago, and Atlanta. Usually barred by custom-and in the South by law-from attending many white entertainment outlets, blacks turned to Negro Leagues games. As a result of these factors, by the 20th century the Negro Leagues were earning a combined millions of dollars. This profitability ended with the desegregation of Major League Baseball. Black fans began attending Major League games, starving the Negro Leagues of its core revenue source. By 1951, the Negro Leagues had ended, although a succession of black star athletes in the Major League had begun.
