Passage: “Coral reefs are sometimes called the rainforests of the sea.” Why might coral reefs be compared to rainforests?
“The forest was eerily quiet. No birds sang, and the usual rustle of small animals had stopped. Then, far off, came a low rumble of thunder.” What mood does the author create?

肾上腺皮质在 ACTH 作用下释放哪种激素?
哪项肺功能结果是慢性阻塞性肺疾病(COPD)的典型表现?
把一个红细胞放入很咸的(高渗)溶液中。会发生什么?
A food sample turns purple with biuret reagent but stays yellow-brown with iodine solution. What does the sample contain?
How many grams are in 2.5 kg?
A liquid has a density of 1.2 g/mL. What is the mass of 250 mL of this liquid?
Choose the correct verb: “The pair of gloves ___ on the cart.”
Choose the correct verb: “Neither the nurses nor the doctor ___ aware of the change.”
Choose the meaning of the word in bold: “Infection is an inherent risk of any surgery.”
Which word is closest in meaning to prudent?
答案: B · Both are home to a great variety of life.
Rainforests are known for their huge variety of living things, and coral reefs also support many species, so the comparison highlights rich biodiversity.
答案: A · Tense and uneasy
The strange silence and the distant thunder build a tense, uneasy mood.
答案: x = 2
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: 1 13/25
分数的乘除:先把带分数化成假分数(2 1/3 = 7/3)。乘法:分子乘分子,分母乘分母。除法:保留第一个分数,把 ÷ 改成 ×,并把第二个分数颠倒(乘以它的倒数)。约去公因数,把结果化成最简带分数。
答案: C · 左前降支
左前降支(前室间支)供应左心室前壁和室间隔前三分之二。它的阻塞会导致前壁梗死。
答案: C · 食管
后纵隔内有食管、降主动脉、奇静脉和胸导管。心脏和升主动脉在中纵隔;胸腺在上纵隔和前纵隔。
答案: A · 皮质醇
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: D · FEV1/FVC 比值低于 0.7
气道狭窄使呼气减慢,因此 FEV1 的下降多于 FVC,比值降到 0.7 以下。在 COPD 中,这种改变不能被支气管扩张剂完全逆转。
答案: A · 水离开细胞,细胞皱缩
外部溶液的溶质更多,所以水通过渗透离开细胞,细胞皱缩(呈锯齿状)。在低渗溶液中则发生相反的情况。
答案: D · Protein but no starch
Biuret reagent turns purple when protein is present. Iodine turns blue-black with starch, so staying yellow-brown means there is no starch.
答案: C · 2500 g
Multiply by 1000 to go from kilograms to grams: 2.5 × 1000 = 2500 g. Going to a smaller unit always gives a bigger number.
答案: A · 300 g
1.2 g/mL × 250 mL = 300 g. Dividing 250 by 1.2 gives about 208, which has the wrong units (mL²/g).
答案: D · is
“Pair” is singular, so it takes “is”. The phrase “of gloves” does not change the subject.
答案: A · was
When subjects are joined by “or” or “nor”, the verb agrees with the nearer subject. “Doctor” is singular, so the verb is “was”.
答案: A · Built-in
Inherent means existing as a natural, permanent part of something.
答案: C · Sensible
Prudent means showing care and good judgement, which is being sensible.
