Unit 4 单元加餐练Ⅰ.阅读理解Every day we experience one of the wonders of the world around us without even realizing it. It is not the amazing complexity of television, nor the impressive technology of transport. The universal wonder we share and experience is our ability to make noises with our mouths, and so transmit ideas and thoughts to each other's minds. This ability comes so naturally that we tend to forget what a miracle (奇迹) it is.Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature's talent show, humans are a species of animal that have developed their own special act. If we reduce it to basic terms, it's an ability for communicating information to others by varying sounds we make as we breathe out.Not that we don't have other powers of communication. Our facial expressions convey our emotions, such as anger, or joy, or disappointment. The way we hold our heads can indicate to others whether we are happy or sad. This is so-called “body language”.Bristling (直立的) fur is an unmistakable warning of attack among many animals. Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering.Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn't tell us how that part of our bodies originated in our biological history.语篇解读:本文讲述了人类使用语言的能力、人类与其他动物共有的“身势语”以及动物如何使用“身势语”。

1.According to the passage, the wonder we take for granted is ________.A.our ability to use languageB.the miracle of technologyC.the amazing power of natureD.our ability to make noises with mouth解析:选A细节理解题。

根据第一段的叙述可知,我们每天都在用语言交流我们的思想感情,这可谓是一个奇迹,但是因其自然流露,我们完全忽视了它的功能与作用,想当然地认为就是这个样子。

D项有一定干扰性,但叙述不完全。

根据第三段中“Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering.”可知,俯首是人和动物表示服从的共同之处。

3.What does the underlined word “it” in the second paragraph refer to?A.Nature's talent show.B.A species of animal.C.A special act of humans.D.Information communicated to others.解析:选C代词指代题。

根据语境可知此处“it”是就近指代上一句中的“their own special act”,即“人类所形成的自己的独特的行为”。

句意:如果我们用最简单的词语来概括它的话,那是一种通过变化我们呼气时所发出的声音来向别人交流信息的能力。

4.This passage is mainly about ________.A.the development of body languageB.the special role humans play in natureC.the power to convey information to othersD.the difference between humans and animals is language use解析:选C主旨大意题。

Ⅱ.阅读七选五Pumpkin (南瓜) powerEvery year about 640,000 kilograms of pumpkins are grown in the US. __1__ Many are used to celebrate Halloween, the night of October 31st. Halloween is a big celebration in America. One tradition that many people enjoy is to carve faces in pumpkins, put a light inside and put the pumpkins around their houses. After Halloween they throw all the pumpkins away.__2__ They use them to produce electricity. Food waste is taken from supermarkets and restaurants and put into large tanks (罐子). Inside these tanks, bacteria break down the food waste, which gives off methane gas. Then the gas is burned to produce electricity — enough electricity topower 13,000 homes.Reusing food waste provides a cheap source of fuel for producing electricity. __3__ Methane gas in the atmosphere is one of the causes of global warming. When food waste is buried in the ground, it can take 40 to 100 years to break down, and over that time it slowly gives off all the methane gas into the atmosphere. But when food waste is kept inside the tanks, it breaks down in about three months. __4__Other cities around the world are now following Oakland's example and using food waste to produce electricity. __5__A.Not all of the pumpkins are eaten.B.To solve the problem, we should reduce waste.C.But there are other good reasons to reuse food waste too.D.Farmers around the country work hard to grow pumpkins.E.Maybe the next time you turn on the lights, they'll be powered by pumpkins!F.Instead of going into the atmosphere, most of the methane gas is kept and used.G.But people in Oakland have found a way to use all those pumpkins and other food waste.语篇解读:本文是说明文。
