Choose the meaning of the word in bold: “The toddler may have ingested a cleaning product.”
What does the term dysphasia mean?
答案: D · To drive safely on the slippery road
Icy roads are slippery, so driving slowly and leaving space helps avoid skidding and crashes.
答案: B · No, she does 140 minutes, 10 short
5 × 20 = 100 minutes of walking plus 40 minutes of cycling = 140 minutes, which is 10 minutes short of 150. So she does not meet it.
答案: x = 160000 cm
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: n = 8 月
应用题:给未知数命名(例如 x = 月数),把已知事实写成一个方程,解出它,并检查答案在题目情境中是否合理。固定费用加上每单位的费率,得到总额 = 费用 + 费率 × 单位数。
答案: B · 心肌层
心肌层是厚厚的中间肌层。心内膜衬于心腔内面,心外膜覆盖外表面。
答案: D · 它撕裂了旋股内侧动脉的支持带支
股骨头主要由沿股骨颈走行的旋股内侧动脉支持带支供血。移位的股骨颈骨折会撕裂这些血管,股骨头可能因此坏死。
答案: C · 纤维蛋白
凝血酶把可溶性纤维蛋白原转化为不溶性的纤维蛋白丝,后者黏合血小板栓并网罗红细胞,形成稳定的血凝块。
答案: D · 抗利尿激素分泌不当综合征
在 SIADH 中,过多的 ADH 使肾脏保留水分,稀释血浆,而尿液保持浓缩。小细胞肺癌可以分泌 ADH。
答案: A · G–C pairs form three hydrogen bonds, and A–T pairs form two
G–C pairs form three hydrogen bonds and A–T pairs form two. DNA rich in G–C therefore needs more energy (a higher temperature) to separate the strands.
答案: D · 沉默突变
因为多个密码子编码同一种氨基酸,所以有些碱基改变不会改变蛋白质。这些就是沉默突变。
答案: D · It floats
An object less dense than the liquid floats. Because 0.8 g/cm³ is less than 1.0 g/cm³, the block floats on water.
答案: B · They have the same average kinetic energy, but H₂ molecules move faster
At the same temperature, all gases have the same average kinetic energy. Because KE = ½mv², the lighter H₂ molecules must move faster to have the same energy as heavier O₂ molecules.
答案: D · Mrs. Patel, your room is ready.
When you speak directly to someone, their name is separated from the rest of the sentence with a comma (or two commas if it is in the middle).
答案: A · privilege
“Privilege” is spelled p-r-i-v-i-l-e-g-e, with no d and an i in the second syllable.
答案: B · Swallowed
To ingest is to take something into the body by swallowing it.
答案: A · Impaired ability to use or understand language
Dysphasia is impaired speech or language; it is easily confused with dysphagia, which means difficulty swallowing.
