公式表、每个专题的关键方法步骤和 16 道练习题,完整解答附在最后。
Coral reefs cover less than one percent of the ocean floor, yet they are home to about a quarter of all marine species. Warmer water can cause corals to lose the algae that feed them, a process called bleaching. What does the word “yet” signal in the first sentence?
The dosage chart reads: “Weight 10–14 kg: 5 mL. Weight 15–19 kg: 7.5 mL. Weight 20–29 kg: 10 mL. Give every 6 hours as needed, no more than 4 doses in 24 hours.” A child weighs 18 kg. What is the most this child may receive in 24 hours?
解出 x:7(x + 8) = 119。
涨薪 10% 之后,一名护理助理每周挣 $148.5。涨薪前的每周工资 x 是多少美元?
哪对脑神经支配斜方肌和胸锁乳突肌?
肱骨干中段骨折后,患者不能伸腕和伸指(“垂腕”)。最可能损伤的是哪条神经?
在骨骼肌中,收缩所需的大部分钙来自哪里?
为什么 T1 以上的高位脊髓损伤患者有低血压风险?
哪种键把氨基酸连接成蛋白质?
Liver cells take in cholesterol-carrying LDL particles only after the particles bind to specific proteins on the cell surface. Which process is this?
Why does water boil at a lower temperature at the top of a high mountain?
某溶液的氢离子浓度为 1 × 10⁻⁹ mol/L。它的 pH 是多少,是酸性还是碱性?
Which salutation is punctuated correctly for a formal business letter in American style?
Choose the correct verb: “If you heat ice, it ___.”
Choose the meaning of the word in bold: “The surgeon will excise the mole.”
What does the term anuria mean?
答案: D · A contrast between the reefs’ small area and their many species
“Yet” contrasts the small size of reefs with the large number of species they support.
答案: B · 30 mL
18 kg falls in the 15–19 kg row: 7.5 mL per dose, up to 4 doses: 7.5 × 4 = 30 mL in 24 hours.
答案: x = 9
解方程:对等式两边做同样的操作,直到 x 单独在一边。按相反的顺序撤销运算:先撤销加法或减法,再撤销乘法或除法。用分配律 a(x + b) = ax + ab 去掉括号,并把含 x 的项合并到一边。把答案代回去检验。
答案: x = 135 $
逆向百分数:当一个数值已经按某个百分数增加或减少后,新值是原值的百分之几,而不是反过来。打八折(减 20%)后,价格是原价的 80%,所以原价 = 新价格 ÷ 0.80。千万不要把 20% 加回新价格上。
答案: B · 副神经(XI)
副神经(XI)支配胸锁乳突肌和斜方肌。损伤会使转头和耸肩无力。
答案: C · 桡神经
桡神经走行于肱骨干的桡神经沟(螺旋沟)内。它支配伸腕肌和伸指肌,因此损伤会导致垂腕。
答案: A · 肌质网
T 管去极化打开肌质网上的雷诺丁受体,把储存的钙释放到细胞质中。
答案: B · 通往血管和心脏的交感神经输出被切断
交感输出在 T1–L2 离开脊髓。高于此处的损伤会去除血管张力和心脏的交感驱动,而迷走神经仍在工作,导致低血压和心动过缓(神经源性休克)。
答案: C · 肽键
氨基酸由脱水缩合形成的肽键连接。糖苷键连接糖,酯键存在于脂肪中。
答案: B · Receptor-mediated endocytosis
In receptor-mediated endocytosis, the substance binds to specific receptors, and that part of the membrane folds in to form a vesicle. Pinocytosis takes in fluid without such specificity, and exocytosis releases material.
答案: D · The air pressure is lower, so less vapour pressure is needed to boil
At high altitude the atmospheric pressure is lower, so water's vapour pressure reaches it at a lower temperature. Water therefore boils below 100 °C, and food takes longer to cook.
答案: C · pH 9,碱性
pH = −log(10⁻⁹) = 9。pH 高于 7 为碱性。定义中的负号使 pH 为正值。
答案: A · Dear Dr. Smith:
In American business letters a colon follows the salutation, and a comma is used in friendly letters. British letters normally use a comma or no mark (“Dear Dr Smith,”).
答案: D · melts
For general truths, the zero conditional uses the present tense in both clauses: “If you heat ice, it melts.”
答案: A · Cut out
To excise is to remove by cutting out.
答案: A · Absence of urine production
Anuria is the absence (or near absence) of urine production, a sign of severe kidney failure or obstruction.
