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。
“The tide was coming in fast. The children, busy building their sandcastle, did not notice the water creeping closer and closer.” What is most likely to happen next?
“Many people think nurses simply follow doctors’ orders. In reality, nurses assess patients, plan care, teach families and often notice early warning signs before anyone else.” What is the author’s main purpose?
不用计算器计算 x = 7.2 ÷ 0.4。给出精确值。
表格显示了 2024 年和 2025 年中心 A、B 和 C 的志愿者人数。 中心 B 这两年每年的平均志愿者人数 x̄ 是多少?
哪块肌肉是肘关节的主要伸肌?
垂体肿瘤向上生长,导致双眼外侧(颞侧)半视野缺失。视觉通路在哪里受压?
除了降低血糖外,胰岛素还把哪种离子转移到细胞内?这一作用被用于治疗高钾血症。
一个健康人躺着后迅速站起。哪个反射能防止晕厥?
Why is a buffer system important in blood?
在基因起始部位附近插入了一个多余的碱基。为什么这通常会对蛋白质产生很大的影响?
A reaction has a theoretical yield of 20 g, but only 15 g of product is collected. What is the percent yield?
An isotope has a half-life of 8 days. How long does it take for 100 g to decay to 12.5 g?
Which sentence is written in the first person?
Which choice correctly fixes the run-on sentence? “The patient was cold she asked for a blanket.”
Choose the meaning of the word in bold: “The surgeon will excise the mole.”
Choose the word that best completes the sentence: “The nurse spoke in a ___ voice so the frightened child would feel safe.”
答案: C · The rising water will reach the sandcastle.
The tide is rising and the children are not paying attention, so the water will most likely reach and wash away the sandcastle.
答案: B · To challenge a narrow view of nursing
The author corrects the view that nurses only follow orders by describing the wide range of their responsibilities.
答案: x = 18
小数:加减时,把小数点对齐。乘法时,按整数相乘,积的小数位数等于两个因数小数位数之和。除以小数时,把两个数的小数点同时向右移动相同的位数,直到除数变成整数。
把两个数都乘以 10,使除数变成整数。
答案: x̄ = 267.5
平均数、中位数、众数和极差:平均数是各值之和除以值的个数。中位数是把各值按顺序排列后位于中间的值;个数为偶数时,它是中间两个值的平均数。众数是出现次数最多的值。极差是最大值减去最小值。
答案: B · 肱三头肌
肱三头肌止于尺骨鹰嘴,使肘关节伸展。肱二头肌和肱肌是屈肘肌。
答案: A · 视交叉
双颞侧偏盲是由于视交叉处交叉的鼻侧纤维受压所致,视交叉正好位于垂体上方。
答案: A · 钾
胰岛素刺激 Na⁺/K⁺-ATP 酶,使钾转移进入细胞。因此胰岛素加葡萄糖被用来降低危险的高血钾。
答案: B · 压力感受器反射使心率加快、血管收缩
血液淤积在腿部,血压下降;压力感受器发放减少,几秒内交感活动增强、迷走活动减弱,心率和血管张力随之升高。
答案: D · It resists changes in pH
Buffers, such as the bicarbonate system, take up or release hydrogen ions to keep blood pH within a narrow range. Even small changes can disturb enzymes and other proteins.
答案: B · 它使其后所有密码子的阅读框发生移位
插入或缺失的碱基数不是 3 的倍数时会造成移码:其后所有密码子都被错误读取,常产生无功能的蛋白质。
答案: C · 75%
15 ÷ 20 × 100 = 75%. Percent yield above 100% would point to an error, such as a wet or impure product.
答案: A · 24 days
100 → 50 → 25 → 12.5 is three half-lives. 3 × 8 days = 24 days.
答案: D · I checked the results twice.
First person uses I or we, second person you, third person he, she, it or they.
答案: A · The patient was cold, so she asked for a blanket.
A uses a comma followed by the conjunction “so”. B is a comma splice, C puts the comma after “so” instead of before it, and D uses a semicolon with an unneeded comma.
答案: B · Cut out
To excise is to remove by cutting out.
答案: C · soothing
Soothing means gently calming and comforting.
