【简答题】
US student Vanessa Tahay stands out from the other teenagers in her school.Her skin is dark and her accent is thick. If you ask her, she will tell you these are the things she is proudest of. Tahay is a poet, and at 18 she was considered among the best in Los Angeles. When she is on the stage, audiences often go silent. They also laugh, shout and cry.But this doesn’t come easily for someone who comes from a village that sits at the base of a huge mountain range in Central America.When she first appeared at school, she was teased by others for being short and different.She never spoke, so they called her “mouse” . “How do I defend myself?” Tahay thought.“I don’t know how.” “Keep going,” her mother would tell her. “At some point, you’ll learn.” She spent hours after school and on weekends watching the same DVD: English Without Barriers . Tahay’s elder brother, Elmer, persuaded her to go to the after­school poetry club. In the last six years, her English teacher Laurie Kurnick has turned Cleveland Charter High School’s poetry program into one of the most respected in the city.Her team draws from the likes of D . H.Laurence, Pat Mora and Kendrick Lamar to create poems about their own lives. The poems focus on many things — some funny, some painful. The first time Tahay read the group’s poems, she was wild with joy. “I wish I could write like that,” she thought.“I want to say something.” She wrote her first poem about her first year in America. She called it Invisible . The day her turn came to recite poems in front of the team, she broke down crying. She cried for 15 minutes.“I had so much held in,” Tahay said.“I couldn’t even finish it.” But she kept at it despite her less­than­perfect grammar, spelling and diction ( 措辞 ). Still, she wouldn’t tell her friends about her poetry because she worried they would make fun of her. But with time, her poems changed her. “They gave me pride,” Tahay said. “They told me that I’m worth something.” “She had this innocence,” Kurnick said. “This willingness to be genuine shows you things you don’t ever see.”

【简答题】冬至日,我国某中学地理学习小组利用日影来测定本校的位置和方向。该小组在A点立1根长1.2米的直竿,并以该点为中心画一圆;上午和下午的某一时刻直竿的日影顶端刚好与圆相交于E、F两点,日影到达E、F的北京时间分别是11:27和12:21。作AN垂直于EF,第二天,当直竿日影恰好与AN重合时,日影的长度为1.69米。(tan35.3°=0.71)。根据图5完成第10题。 10.关于当地的经纬度和方向表述...
【多选题】What are the composition and function of high-density lipoprotein (HDL)?
A.
As a major lipoprotein in mammals, high-density lipoprotein (HDL) originates in the liver and small intestine as small, protein-rich particles that contain relatively little cholesterol and no cholesteryl esters. HDLs contain primarily apoA-I and other apolipoproteins. They also contain the enzyme lecithincholesterol acyl transferase (LCAT), which catalyzes the formation of cholesteryl esters from lecithin (phosphatidylcholine) and cholesterol.
B.
LCAT on the surface of nascent (newly forming) HDL particles converts the cholesterol and phosphatidylcholine of chylomicron and VLDL remnants encountered in the bloodstream to cholesteryl esters, which begin to form a core, transforming the disk-shaped nascent HDL to a mature, spherical HDL particle. Nascent HDL can also pick up cholesterol from cholesterol-rich extrahepatic cells including macrophages and foam cells, formed from macrophages.
C.
Mature HDL then returns to the liver, where the cholesterol is unloaded via the scavenger receptor SR-BI. Some of the cholesteryl esters in HDL can also be transferred to LDL by the cholesteryl ester transfer protein. The HDL circuit is reverse cholesterol transport.
D.
Much of this cholesterol is converted to bile salts by enzymes sequestered in hepatic peroxisomes; the bile salts are stored in the gallbladder and excreted into the intestine when a meal is ingested. Bile salts are reabsorbed by the liver and recirculate through the gallbladder in this enterohepatic circulation.
