What is the function of the underlined word? “Swimming is good exercise for the heart.”
Choose the meaning of the word in bold: “Drinking enough fluids helps prevent constipation.”

答案: A · Frustrated
Sighing, throwing the tickets and noting it is the third cancellation show frustration.
答案: B · To put her nephew at ease
The wink and her light remark suggest she wanted to calm her nervous nephew rather than scold him.
答案: A = 15 m²
周长、面积和体积:周长是围绕图形一周的长度(长方形:2l + 2w)。面积以平方单位计量:长方形 l × w,三角形 ½ × 底 × 高,圆 π·r²。圆的周长是 π·d = 2π·r。体积以立方单位计量:长方体 l × w × h,圆柱 π·r²·h。使用题目给出的 π 值。
答案: x = 6 杯
比与比例:比 a : b 比较两个量。比例中两个比相等,a/b = c/d,用交叉相乘求解:a·d = b·c。把一个量按 m : n 分配,就把它分成 m + n 等份;一方得 m 份,另一方得 n 份。
答案: A · 颈内动脉系统和椎-基底动脉系统
Willis 环把颈内动脉与基底动脉(由椎动脉汇合而成)连接起来,可提供一定的侧支血流。
答案: C · 腋神经
腋神经绕肱骨外科颈走行,支配三角肌和小圆肌以及肩外侧皮肤(“团徽”区)。
答案: A · 每搏输出量 ÷ 舒张末期容积
射血分数是充盈的心室中每搏射出的血量所占的比例。正常值约为 55–70%。
答案: D · 它与 2,3-BPG 的结合较弱
HbF 的 γ 链与 2,3-BPG 结合很差,因此解离曲线左移。这使胎儿血液能在胎盘中从母体血液中获取氧气。
答案: D · The smallest fragments
Smaller fragments slip through the pores of the gel faster and travel further. Large fragments stay closer to the wells where the samples were loaded.
答案: B · The lion and the tiger
The lion and tiger share the genus Panthera, while the house cat is in a different genus. Sharing a lower rank, such as genus, means a closer relationship than sharing only a family.
答案: C · 2−
Group 16 atoms have 6 valence electrons and gain 2 to reach 8, forming ions such as O²⁻ (oxide) and S²⁻ (sulfide).
答案: B · Group 1 (alkali metals)
Alkali metals such as sodium and potassium react with water to form a hydroxide (a base) and hydrogen gas. Halogens and noble gases are nonmetals and do not conduct.
答案: C · The clinic opens at eight, it closes at five.
Joining two independent clauses with only a comma is a comma splice. Fix it with “, and”, a semicolon or a full stop.
答案: D · It is a gerund used as the subject.
A gerund is an -ing verb form used as a noun. Here “swimming” is the subject of the verb “is”.
答案: D · Difficulty passing stools
Constipation means infrequent or difficult bowel movements, often with hard stools.
答案: D · A disease or disorder of the nerves
Neur/o (nerve) + -pathy (disease). The study of nerves is neurology; a nerve cell is a neuron.
