答案: x = 2880 min
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: x = 12 杯
比与比例:比 a : b 比较两个量。比例中两个比相等,a/b = c/d,用交叉相乘求解:a·d = b·c。把一个量按 m : n 分配,就把它分成 m + n 等份;一方得 m 份,另一方得 n 份。

答案: C · Anaphase I of meiosis
Only in anaphase I do homologous chromosomes separate while each still has two sister chromatids. In mitosis and in anaphase II, the sister chromatids themselves are pulled apart.
答案: A · The air pressure is lower, so less vapour pressure is needed to boil
At high altitude the atmospheric pressure is lower, so water's vapour pressure reaches it at a lower temperature. Water therefore boils below 100 °C, and food takes longer to cook.
答案: D · 正反应和逆反应仍以相等的速率持续进行
平衡时两个反应仍以相同的速率进行,所以浓度保持恒定,但不一定相等。
答案: B · I checked the results twice.
First person uses I or we, second person you, third person he, she, it or they.
答案: C · The instructor taught nearly 40 students.
