“By the end of the first week, Aisha had memorised the names of all thirty children in her class. By the end of the month, she knew which of them liked maths and which loved drawing.” What can you infer about Aisha?
“Researchers gave half of a group of volunteers a new vitamin and the other half a dummy pill. Neither the volunteers nor the researchers knew who got which until the end.” Why did the researchers keep this secret?
用运算顺序求 x 的值:x = 5² − 4 × (12 − 4) + 10。
在地图上,1 cm 代表 20 km。两个城镇相距 280 km。它们在地图上相距多远 x(单位:厘米)?
肝门静脉由哪两条静脉汇合而成?
胸导管通常在哪里把淋巴注入血液?
哪种 ABO 血型的血浆中同时含有抗 A 和抗 B 抗体?
为什么乳糖酶缺乏的人喝牛奶后会腹泻和腹胀?
DNA 模板链的序列是 T-A-C。与之匹配的 mRNA 密码子是什么?
An inhibitor binds to an enzyme away from the active site and changes the enzyme's shape. Adding more substrate does not restore the rate. What type of inhibition is this?
Which halogen is the most reactive?
An element in period 3 forms an oxide with the formula X₂O₃. Which element is X?
Choose the correct preposition: “The patient is allergic ___ penicillin.”
Which phrase shows that Maria and Juan each have their own phone?
Choose the meaning of the word in bold: “Smoking can exacerbate asthma.”
Choose the meaning of the word in bold: “The bleeding was profuse.”
答案: A · She is a teacher who takes an interest in her pupils.
“Her class” of thirty children and learning their interests suggest a teacher who cares about her pupils. A new pupil who keeps forgetting names does not fit, since she memorised them all in a week.
答案: A · To stop expectations from affecting the results
Keeping both groups unaware (a double-blind design) prevents expectations of volunteers or researchers from biasing the results.
答案: x = 3
运算顺序(PEMDAS/BODMAS):先算括号里面的,然后算指数(乘方),再从左到右算乘法和除法,最后从左到右算加法和减法。乘法并不先于除法,加法也并不先于减法:每一对都按出现的先后顺序计算。括号里的负数平方时保留符号:(−3)² = 9,而 −3² = −9。
5² 表示 5 × 5,而不是 5 × 2。
答案: x = 14 cm
速率与比例尺:速度 = 距离 ÷ 时间,时间要用答案所需的单位(2 h 15 min = 2.25 h,因为 15 min = 15/60 h)。地图比例尺是一个比例:地图上的 1 cm 代表地面上的固定距离,所以把地图距离乘以它。
答案: B · 肠系膜上静脉和脾静脉
门静脉在胰颈后方由肠系膜上静脉和脾静脉汇合而成。它把富含营养物质的血液送到肝脏。
答案: C · 左锁骨下静脉与左颈内静脉的汇合处
胸导管把双下肢、腹部和上半身左侧的淋巴引流到左静脉角。右淋巴导管把其余部分的淋巴引流到右静脉角。
答案: A · O 型
O 型血的人没有 A 或 B 抗原,同时产生抗 A 和抗 B 抗体。AB 型有两种抗原,但两种抗体都没有。
答案: A · 未消化的乳糖把水吸入肠道,并被结肠细菌发酵
未被吸收的乳糖产生渗透作用,把水拉入肠腔。结肠细菌将其发酵,产生气体和短链脂肪酸。
答案: C · A-U-G
RNA 聚合酶把每个模板碱基与其对应的 RNA 碱基配对:T→A,A→U,C→G,得到 AUG,即起始密码子。
答案: C · Noncompetitive inhibition
A noncompetitive inhibitor binds at another site and distorts the active site, so extra substrate cannot outcompete it. A competitive inhibitor binds the active site itself, and its effect can be overcome by more substrate.
答案: D · Fluorine
Halogen reactivity decreases down the group. Fluorine is the smallest, so its nucleus attracts an extra electron most strongly, making it the most reactive.
答案: A · Aluminium
Three O²⁻ ions give 6− in total, so two X ions must give 6+, meaning X³⁺. The period 3 metal that forms 3+ ions is aluminium (group 13), giving Al₂O₃.
答案: B · to
The fixed expression is “allergic to” something, just as the noun is “an allergy to”.
答案: C · Maria’s and Juan’s phones
When each person owns something separately, both names take ’s. B would suggest shared phones, and D misplaces the apostrophes.
答案: C · Make worse
To exacerbate is to make a problem or symptom more severe.
答案: D · Abundant and heavy
Profuse means plentiful or in large amounts.
