Are you having so much of work to finish...

Are you having so much of work to finish and are unable to keep your home clean and healthy? Don’t worry. Robotic vacuum cleaners are here to help you in cleaning.

The robotic vacuum cleaners are outfitted with sensors, motherboard, Wi-Fi, and lasers to navigate across the home by themselves. They are made so small that they undoubtedly creep under the furniture, cupboards, beds, carpets and so on to detect and clean the dust. Whereas the robotic vacuum cleaners don’t require any help from you you just need to set it and then carry on your work such as cooking painting, office work, etc. as it can efficiently clean without any supervision. If their batteries die off, they will automatically go to the charge station and get charged.

The robotic vacuum cleaners make very little noise when compared to that of the standard vacuum cleaners. To collect all the dirt and grime that has been cleaned, these robotic vacuum cleaners come with a built-in waste bin. You can with no difficulty clean this inbuilt dustbin and can reuse them again and again.

The problematic thing with the standard vacuum cleaner is that the vacuum bags are costly and has to be replaced once in 60 days. That is why it is best to invest your money in purchasing the robotic vacuum cleaner. Its purchase price may be a little high, but once you buy it, the maintenance cost will be decreased with so many other benefits.

There are different types of robotic vacuum cleaners on the market right now in different sizes. Make a wise decision and buy the best robotic vacuum cleaner that can fulfill all your requirements so that you can be happy and hygienic (卫生的).

1.The underlined word “navigate” in Paragraph 2 is closest in meaning to____.

1. A 2. A 3. C 【解析】 本文是一篇说明文。本文主要介绍一款机器人吸尘器,它具有自行导航、噪音小、维护成本低等特点。 1.词义猜测题。由第一段可知robotic vacuum cleaners是帮助人们打扫的机器,由第二段第一句The robotic vacuum cleaners are outfitted with sensors, motherboard, Wi-Fi, and lasers to navigate across the home by themselves.可知它配备有传感器等装备,所以猜测它可以自主在家中移动。故选A。 2.细节理解题。由第四段Its purchase price may be a little high, but once you buy it, the maintenance cost will be decreased with so many other benefits.可知这里its指代的是the robotic vacuum cleaners,所以是机器人真空吸尘器更贵,但是后续的维修费比机器人真空吸尘器少,因而更值得投资,所以A表达错误。故选A。 3.推理判断题。文章第二段主要写机器人吸尘器自主操控,小而精工作效率高,第三段描写她噪音小易清洁的特点,所以这两段主要写的是吸尘器的特点,两段内容也提到他的功能,这只是为了突出他的特点。故选C。
