Passage 2 Directions: Listen to a short passage three times. When the passage is read for the first time, listen for its general idea. When the passage is read for the second time, fill in the blanks with the exact words you hear. When the passage is read for the third time, check what you have written. My great-great-grandparents were the first in my family to arrive in the U.S., immigrating to this country from Europe. However, I am the first in my bloodline to arrive in the States, as I was adopted from South Korea in my (1) ________. I have for the most part (2) ________ the customs and practices of my adoptive parents because I was raised with their values and know nothing of my biological parents. I only (3) ________ their family name. The significance of my race has been (4) ________ my mind since my mother took my younger brother and me to Asian culture (5) ________ before we had even started school. She did this in an effort to (6) ________ the lack of cultural diversity in the area; my brother and I were the only Asian children at school and in the community. Thus, the realization that there are different “types” of people, as far as race is concerned, actually came to me in meeting other South Koreans. Attending college has helped (7) ________ the idea of my cultural identity, for that was the first time I ever came in contact with other peoples en masse. I was finally able to (8) ________ various races of students and faculty from around the world. Most of my life I had only been (9) ________ white people, so being able to experience how other people lived allowed me to see how I was racially different. This encouraged me to learn more about these differences and how they truly affect how I live. Also, taking college courses with a multicultural focus (10) ________ my perceptions concerning these differences and influences.

举一反三
【多选题】关于速率理论,以下说法正确的是( )
A.
组分分子在柱内运行的多路径与涡流扩散、浓度梯度所造成的分子扩散及传质阻力使气液两相间的分配平衡不能瞬间达到等因素是造成色谱峰扩展柱效下降的主要原因。
B.
通过选择适当的固定相粒度、载气种类、液膜厚度及载气流速可提高柱效。
C.
速率理论为色谱分离和操作条件选择提供了理论指导。阐明了流速和柱温对柱效及分离的影响。
D.
各种因素相互制约,如载气流速增大,分子扩散项的影响减小,使柱效提高,但同时传质阻力项的影响增大,又使柱效下降;柱温升高,有利于传质,但又加剧了分子扩散的影响,选择最佳条件,才能使柱效达到最高。
