Can Cacti Block Harmful Radiation?
Cacti have long been popular plants to keep in living spaces around the world. The fact that cacti are both pleasing to the eye and easy to take care of makes them ideal plants to brighten up homes. Furthermore, cacti offer a number of health-related benefits to humans, such as increasing the amount of oxygen in your home. However, there is a more specific reason why cacti ownership has become more popular in recent years. Specifically, thanks to a lot of questionable information being spread online, many people now believe that keeping cacti on your desk benefits your health because cacti absorb harmful radiation emitted by your computer. Regarding this claim, fact-checking is required.
(误刊通知: 纸本解析杂志五月号 5 月 6日文章第20页，第一段后半部 many people now believe that keeping cacti on your desk benefit your health...中的benefit需加"s"，正确为"benefits"，造成您学习上的困扰，深感抱歉。)
First, some websites state that radiation from computers is responsible for a range of health problems, including insomnia and headaches. On this note, it is important to keep in mind that there are multiple types of radiation. While some are indeed harmful, the amount of radiation emitted by computers is not enough to damage human health.
Next, regarding the question of whether cacti can actually absorb radiation from a computer, the simple answer is no, they can’t. This is because radiation from a computer would be emitted in all directions. Therefore, a cactus positioned on one side of your computer will do nothing to stop radiation from traveling straight towards you from the front of the machine.
In summary, cacti cannot prevent you from absorbing radiation from your computer. However, such radiation will actually do you no harm. Having said that, keeping cacti in your home provides a number of real advantages that can help you live a happier and healthier life.
1. What does the word “questionable” in the first paragraph most likely mean?
(A) Reliable.

(C) Hard-to-answer.
(D) Easy-to-understand.
2. How are cacti helpful for human health?
(A) They help people fall asleep.
(B) They are good for your eyes.

(D) They raise oxygen levels.
3. How does the author feel about the claim that cacti can block harmful radiation?
(A) It needs further investigation.
(B) It is true and in urgent need of attention.
(C) It is inaccurate and the facts should be clarified.
(D) It should be valid because it has been published online.
4. If a plant could absorb radiation from computers, where should one place it to effectively lower one’s exposure to radiation?
答案： 1. B 2. D 3. C 4. B

比较 number 及 amount 的用法
number 和 amount 都是用来表达东西的「数量」，但前者是指「可数名词」的数量，而后者则是指「不可数名词」的数量，重要用法如下：
※ a number of + 复数名词 若干∕一些……
an amount of + 不可数名词 若干∕一些……
a number of 及 an amount of 为形容词，其后分别接复数名词和不可数名词，故置于句首作主词时，其后动词要随 of 后的名词作变化。
• A number of cars were driving on the hill during the speed game.
许多汽车在速度竞赛时奔驰于斜坡上。
• An amount of pepper was added to the soup to enhance the flavor.
一些胡椒被加入那碗汤里以增添风味。
※ 在 a number of 及 an amount of 的用法中，number 及 amount 前加入 small、large、great 等形容词，表「少量∕少数的……」或「大量∕多数的……」。
• Kayla is beautiful and smart; no wonder she has a large number of friends.
凯拉漂亮又聪明；难怪她有一大群朋友。
• Only a small amount of paper we consume is recycled.
我们消耗的纸张只有少量被回收。
※ the number of + 复数名词 ……的数目
the amount of + 不可数名词 ……的数量
the number of... 和 the amount of... 作主词时，后面的动词用第三人称单数。
• The number of students registering for this course has reached 30.
登记这门课程的学生人数已经有三十人了。
• The amount of food and water that the refugees received was far from enough.
灾民们所获得的食物与水根本不够。
※ 一般而言，amount 用来修饰不可数名词，但现今已演变成能接可数名词及不可数名词的模糊地带：亦即可数名词「由于数量过于庞大以至于不可数」的状况下，整体可视为不可数名词，用 amount 来表示。
• The storm blew off a large amount of leaves from the trees.
暴风雨吹落了树上大量的树叶。

仙人掌可以阻挡电脑辐射吗？
仙人掌在全世界长久以来都是受欢迎的室内植物。仙人掌赏心悦目也很容易照顾的特质，让它们成为能使家里生气蓬勃的绝佳植物。此外，仙人掌也为人类带来一些健康方面的益处，像是增加家里的氧气量。但是，近年来为何养仙人掌变得更受欢迎有一个更明确的原因。具体来说，多亏了很多在网路上散播的不确定资讯，许多人现在相信在桌上养仙人掌对健康有益，因为仙人掌能吸收电脑发出的有害辐射。关于这项主张，需要事实查核。
首先，一些网站声明来自电脑的辐射是各种健康问题的原因，包含失眠和头痛。说到这点，重要的是要记住有很多种辐射存在。虽然有些确实是有害的，但电脑散发出的辐射量并不足以伤害人类的健康。
接着，关于仙人掌是否真的能吸收电脑辐射这个问题，答案很简单，是不，它们不能。这是因为电脑的辐射是朝四面八方散发。因此，一株放在电脑旁的仙人掌并无法阻止辐射从你面前的机器直接朝你行进。
简言之，仙人掌无法阻止你吸收电脑的辐射。但是，这种辐射其实不会对你造成伤害。尽管如此，在家里养仙人掌提供了一些真正的好处，能让你过更开心更健康的生活。
1. 第一段的 “questionable” 最有可能是什么意思？

4. 如果有一种植物能吸收来自电脑的辐射，应该把它放在哪里才能有效降低辐射的接触呢？
题解: 根据本文第三段，电脑的辐射是朝四面八方散出，而使用电脑时通常是坐在萤幕正前方，所以若要有效降低辐射的接触，应将植物放在自己与电脑萤幕正中间，故选 (B)。
