“Mobile clinics now travel to farming villages twice a month. Before, people had to travel three hours to the nearest doctor.” What is the main benefit of the mobile clinics?
A clinic policy reads: “Patients more than 15 minutes late may be asked to rebook. Patients who call ahead to say they are running late will be seen if time allows.” A patient arrives 20 minutes late without calling. What is most likely to happen?
一双鞋标价 $187.75。现在打 20% 的折扣,并在折后价上加 8% 的销售税。最终价格 P 是多少?四舍五入到分。
你前 5 次考试的分数是 96, 83, 77, 75, 87。下一次考试要得多少分 x,才能使全部 6 次考试的平均分恰好为 83?
哪对脑神经控制舌的运动?
肱骨外科颈骨折后,患者手臂外展不能超过约 15°,且肩外侧皮肤麻木。最可能损伤的是哪条神经?
下列哪一项是体内正反馈的经典例子?
为什么胎儿血红蛋白对氧的亲和力高于成人血红蛋白?
饱和脂肪与不饱和脂肪有何不同?
In snapdragons, flower colour shows incomplete dominance: RR is red, RW is pink and WW is white. Two pink plants are crossed. What phenotype ratio is expected?
Zn + 2HCl → ZnCl₂ + H₂ 是哪种类型的反应?
Why is incomplete combustion of fuel in a poorly ventilated room dangerous?
Choose the correct verb: “Some of the cake ___ missing.”
Which sentence uses a pronoun with a clear antecedent?
Choose the meaning of the word in bold: “On a busy shift the nurse must prioritise patient care.”
Which word is the opposite of anterior?
答案: C · Easier access to health care
Before, villagers travelled three hours to see a doctor. Mobile clinics bring care to them, making health care easier to reach.
答案: A · The patient may be asked to book another time.
The patient is more than 15 minutes late and did not call ahead, so the first rule applies: they may be asked to rebook. No fine or cancellation is mentioned.
答案: P = 162.2 $
折扣与销售税:d% 的折扣后剩下价格的 (100 − d)%;t% 的税是在折后价上再加 t%。按这个顺序计算:价格 × (1 − d/100),然后 × (1 + t/100)。金额只在最后四舍五入到分。
答案: x = 80
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 · 舌下神经(XII)
舌下神经支配舌内肌和大部分舌外肌。损伤时伸舌偏向患侧。
答案: D · 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: B · 分娩时催产素的释放
宫颈受牵拉促使催产素释放,催产素增强宫缩,造成更多牵拉。这个循环以分娩结束。其他例子都是负反馈。
答案: A · 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: A · 它们没有 C=C 双键,通常是固态
饱和脂肪酸只有单键,所以堆积紧密,呈固态(如黄油)。不饱和脂肪中的双键造成弯折,所以是油。
答案: B · 1 red : 2 pink : 1 white
RW × RW gives 1 RR : 2 RW : 1 WW. Because heterozygotes are pink, the phenotype ratio is the same as the genotype ratio: 1 red : 2 pink : 1 white.
答案: D · 置换反应
锌取代了 HCl 中的氢:A + BC → AC + B,是置换反应。
答案: B · It produces carbon monoxide, which binds to haemoglobin and blocks oxygen transport
With limited oxygen, fuels form carbon monoxide (CO) instead of CO₂. CO binds to haemoglobin far more strongly than oxygen, so less oxygen reaches the tissues. It is colourless and odourless.
答案: A · is
“Some”, “all”, “most” and “none” take their number from the noun that follows. “Cake” here is singular, so the verb is “is”.
答案: B · When Ana met Lena, Ana gave her a gift.
In the other sentences “she” could mean Ana or Lena. Repeating the name removes the ambiguity.
答案: B · Decide what is most important first
To prioritise (US: prioritize) is to arrange tasks in order of importance and deal with the most urgent first.
答案: D · Posterior
Anterior means front and posterior means back.
