Mia says: "Our class should water the vegetable garden in the morning, not in the afternoon. In the afternoon the sun is hot, so a lot of the water dries up before the plants can use it."
Which one of these statements, if true, most strengthens Mia's argument?
AA.
Beans and tomatoes are the easiest vegetables to grow at school.
BB.
The garden has a tap right next to the classroom door.
CC.
Our class has more free time in the afternoon than in the morning.
DD.
Water given in the morning soaks deep into the soil before the day gets hot.
答案: D
答案:D(早上浇的水在天热之前就深深渗进土里)
Mia的理由是:下午浇的水,还没等植物吸收就被晒干了。
要加强她的论点,就需要证据说明早上浇的水确实能被植物用上。
D说早上浇的水在天热之前就深深渗进土里,植物能吸收到。这正好支持了她选择早上浇水。
为什么其他选项不对
A:说的是菜园适合种什么,和什么时候浇水效果好无关。
B:水龙头在哪里,不影响早上还是下午浇水更好。
C:这是下午浇水的理由,反而削弱了Mia的论点,而不是加强。

Ella says: "Students at our school do not like fruit. The canteen sells fruit cups every day, but hardly anyone buys them."
Which one of these statements, if true, most weakens Ella's argument?
AA.
The fruit cups are kept in a fridge behind the counter, out of sight.
BB.
Pies are the food that sells best at the school canteen.
CC.
The canteen opens before school starts and again at lunch.
DD.
When free fruit is handed out at sport, most of it is left over.
答案: A
答案:A(水果杯放在看不到的地方)
Ella唯一的证据是:几乎没有人买水果杯。
A给出了卖得少的另一个原因:水果杯放在柜台后面的冰箱里,学生看不到,可能根本不知道有卖。
这样一来,卖得少就不能说明学生不喜欢水果了。
为什么其他选项不对
B:哪种食物卖得最好,并不能解释水果杯为什么卖得少。
C:小卖部什么时候开门,也解释不了水果杯为什么卖得少。
D:运动时发的免费水果大多剩下,说明学生确实不太想吃水果,这反而加强了Ella的论点。
