V2说一个城市预计会要有a drought period this year which is more severe than in the past. The government is going to set up a series of policies to reduce the water usage in watering plants. However, from the annual water usage report, water used in watering plants consists of only a small portion of the total usage.
问哪一个选项提供的信息可以使政府颁布的法律很effective
我选的是”People tends to use more water watering plants when there is insufficient rainfall to keep plants healthy”
其他选项有:
- The amount of water used in watering plant in the usage report includes water used in public gardens and parks
- The weather prediction sometimes is inaccurate
- 记不得了…
older考古:
有一个市曾经遭遇过干旱灾害,所以为了杜绝再次遭遇这种灾难,市里就规定平时市民要节约使用水灌溉花园。但是(这个but后面我既不太清楚了,好像说这个灾难是偶尔的还是怎么回事),所以这个举措即使实施成功了也不能有效的防治干旱。
答案是当下雨少的时候,人们就会用大量的水来浇她们干枯的花。(因为下雨少的时候就快要发生干旱灾难了嘛,然而越到这个时候市民用来浇花的水就越多)

说给老鼠做实验—— 如果老鼠碰到了正确的lever,在被stone以后5秒内又碰到lever就奖励。如果碰了错误的,在被stone5秒后又碰了lever的不奖励。然后又有个实验吧,说老鼠碰了lever和没碰lever的,一会儿奖励一会儿不奖励。结论是经过训练老鼠可以有识别什么时候碰怎么碰能奖励的能力。
问怎么weaken
A 在另一个老鼠实验中blablah
B 其他动物的实验也有这个能力

Before the construction of bicycle paths, the bicyclists took trips on the road. After the construction of bicycle paths, the trips on those paths almost doubled and the bicyclists also increased. Yet the trips on the road didn’t decline much.

1. 另外就是修了自行车专用车道,但机动车道里面的自行车没有减少。我选的答案是所有走专用车道的人都得经过机动车道。
3. 说一个地方的骑自行车的人老在汽车道上走(road),政府就修了一条自行车道(bycical path)。结果是每天总的bycical trips made 比以前增长了20%,且大多数骑自行车的人都make use of the new bycical path,但是在road 上面骑车的人并没有减少。问假设。答案里面有如果不修新路,总的bycical trips 会不变,还有一个答案是有如果不修新路,总的bycical trips 会下降。只记得这两个答案,当时觉得都挺不贴边的。
4. 一个城市里,自行车运动人之前在路上彪车,后来有了一个专门的场地给他们去彪车,之后自行车运动爱好者的数量增加了20%,而且most of 他们都失去那个专业表车场。however,在路上彪车的人还是没有减少。
问题要求:If the arguement is treu, which of the following must be true?
在彪车场骑车的人的most也在路上骑。(--我觉得是can be true的选项,而不是must be true的选项)
盖好新场地以后,喜欢在路上飙车的自行车爱好者的数量没有减少。(我选了这个)
其他的都是无关的选项。
Mayor: Migrating shorebirds stop at our beach just to feed on horseshoe-crab eggs, a phenomenon that attracts tourists. To bring more tourists, the town council plans to undertake a beach reclamation project to double the area available to crabs for nesting.
Birdwatcher: Without a high density of crabs on a beach, migrating shorebirds will go hungry because shorebirds only eat eggs that a crab happens to uncover when it is digging its own nest.
Which of the following, if true, would provide the mayor with the strongest counter to the birdwatcher’s objection?
A、Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.
B、Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.
C、On average, tourists who come to the town in order to watch birds spend more money there than tourists who come for other purposes.
D、The additional land made available by the reclamation project will give migrating shorebirds more space.
E、Some of the migrating shorebirds make only one stop during their migration form South America to Canada.
“34. GWD17-Q34”:
During the month of May, crabs arrive on Delaware’s beaches to lay eggs. Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds. Delaware’s crab population has declined recently. This decline, however, poses no serious threat to the migrating shorebird populations: by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
Which of the following, if true, most seriously weakens the argument?
No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.
The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.
There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through.
The crabs do not conceal their eggs.
The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.
