Which sentence uses a comma correctly after an introductory word?
Which word in this sentence is used as an adverb? “The surgery went well, and the patient recovered fast.”
Choose the meaning of the word in bold: “Contaminated needles must be placed in a sharps container.”

答案: B · Mix the flour and sugar
“While the oven heats, mix the flour and sugar.” The other steps come afterwards.

The author points out that youth violence fell as games spread, which does not fit the claim. This weakens the claim but does not prove that games reduce crime.
答案: x = 48 杯
单位换算:乘以一个等于 1 的因子,写成能约去旧单位的形式:3 ft × 12 in/1 ft = 36 in。公制长度:1 km = 1000 m,1 m = 100 cm = 1000 mm,1 cm = 10 mm。美制:1 ft = 12 in,1 yd = 3 ft,1 mi = 5280 ft;1 gal = 4 qt,1 qt = 2 pt,1 pt = 2 cups;1 ton = 2000 lb。时间:1 h = 60 min,1 min = 60 s,1 day = 24 h,1 week = 7 days。单位越小,数值越大。
答案: 1 21/200
分数、小数和百分数是书写同一个数的三种方式。分数 → 小数:分子除以分母。小数 → 百分数:乘以 100(小数点右移两位)。百分数 → 小数:除以 100。小数 → 分数:把数字写在 10、100 或 1000 上(每一位小数一个零)再约分。
答案: C · 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: D · 精索
腹股沟管在男性中容纳精索,在女性中容纳子宫圆韧带。股血管则从腹股沟韧带下方经过。

垂体前叶的 ACTH 刺激束状带释放皮质醇。肾上腺素来自肾上腺髓质。
答案: B · ACTH 受到抑制,肾上腺皮质萎缩
外源性糖皮质激素抑制 CRH 和 ACTH,因此肾上腺皮质萎缩。突然停药可能引起肾上腺危象,所以要逐渐减量。
答案: A · CO₂ is built into sugar using ATP and NADPH
The Calvin cycle uses ATP and NADPH from the light-dependent reactions to fix carbon dioxide into sugar. It does not use light directly, but it depends on the products of the light reactions.
答案: B · UAC
反密码子与密码子互补:A–U,U–A,G–C,得到 UAC。RNA 含有 U,不含 T。
答案: B · Pink
Phenolphthalein is colourless in acidic and neutral solutions and turns pink in basic solutions (above about pH 8–10). It is widely used in acid–base titrations.
答案: D · 1/8
After each half-life the amount is halved: 1 → 1/2 → 1/4 → 1/8. After n half-lives, (1/2)ⁿ remains.
答案: B · Yes, the lab results are back.
An introductory word such as yes, no, well or however is followed by a comma. A comma should never split a subject from its verb.
答案: C · fast
“Fast” tells how the patient recovered, so it is an adverb (like “well”). Words such as fast, hard and late can be adjectives or adverbs.
答案: B · Made unclean by germs or harmful matter
Contaminated means made impure by contact with something harmful, such as blood or germs.
答案: C · On both sides, and near the trunk
Bilateral means affecting both sides of the body; proximal means closer to the trunk or point of origin.
