题目内容
Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.
Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light（紫外线）, which is present on many flowers and guides butterflies to honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae（触角）, feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.
Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations（振动）.
Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.
1.What can we learn from the 2nd paragraph?
A. Butterflies have good eyesight.
B. Butterflies can see in all directions and don't need to turn heads.
C. Butterflies are sensitive to bright colors including red and yellow.
D. Butterflies cannot sense the ultraviolet light.
2.How do butterflies hear sounds?
A. Using their feet to sense the vibration of things
B. Using their ears to listen directly
C. Using their wings to sense the sound vibrations
D. Using their antennae to judge the sound

A. To find high-qualified honey.
B. To have a good place for living.
C. To make it easier for them to hide from the enemies.
D. To find a proper place for their eggs.
4.What does the last paragraph imply?
A. There’s a long way to understand butterflies well
B. Butterflies give great help to human beings
C. Butterflies are the most beautiful insects in the world

【解析】试题分析：本文主要介绍了蝴蝶的几种感觉：视觉，嗅觉，听觉和触觉。在作比较中将几种感觉说得生动而明晰。虽然人类了解了蝴蝶的大致构造，但是由于蝴蝶与人类身体结构很不一样，故目前阶段的了解还是浅显的。对于蝴蝶的研究还有很长一段路要走。
1. have large compound eyes, which allow them to see in all directions without turning their heads.”可知，蝴蝶有很大的复眼，所以它们能够不转头就看到所有方向。故选B。
2. receptors are located in their antennae, feet, and many other parts of the body.第二句说明感觉受体很多，有触角、脚和身体的其他部位。而蝴蝶的翅膀也差不多就是整个身体。故选C，它们用翅膀感觉事物的震动。
3. females also carefully choose host plants by tasting to find appropriate places to lay their eggs.“一些雌性蝴蝶为了找到一个合适的地方产卵会通过仔细品尝来挑选寄主植物”易知雌性蝴蝶品尝寄主植物的目的就是为了找个合适的地方产卵。故选D。
4. may possess senses we don't even know about yet, because their body structure is very different from ours“蝴蝶也许还拥有我们不知道的感觉，因为他们的身体结构与我们人类的很不一样。”可知我们还不是很了解蝴蝶，对蝴蝶还需要很多的研究。故选A。

考点：考查说明文阅读。
When Barbra Streisand discovered in 2003 that a photograph of her California beach house was among 12,000 photos on the Internet as part of a collection by photographer Kenneth Adelman, she did what any famous person would do: hit him with a $50 million lawsuit. But in trying to hold back the images, she caused a different outcome. Her legal actions led to almost half a million people visiting the website, viewing and copying the photos within a month.
Ever since then, the effect of letting public know something you are trying to keep secret has been called the “Streisand effect”. The problem for anyone trying to suppress information is that the Internet is the world’s biggest and most efficient copying machine. Put a document on to a connected machine and it will spread. So when you want to be famous, you can’t, but if you find yourself in the spotlight and want to erase yourself, you cannot.
There is no shortage of examples of the Streisand effect. Nine-year-old Martha Payne created a simple blog, posting the meals her school served. She took a photo of what was barely a filling meal by anyone’s standards. With the photo, she filled a comment, “Now Dad understands why I am hungry when I get home.” The thing did not go too far, until the local authority banned little Martha from doing that again. Martha posted a supposedly final post called “Goodbye”, explaining everything. Once the media found this out, things went from bad to worse for the authority. Now the blog has more than 9.5 million page views. Martha has even expanded her blog by including pictures of school meals taken by other kids from all over the world, like Germany and Japan.
We can find similar examples throughout history, to be frank. Man has experienced the Streisand effect ever since the birth of mass communication. Why does it exist? Every time you are told not to see what’s in the secret shiny box wrapped in gift paper, you’re going to do everything in your power to do exactly that! Just realizing that knowing something about someone is harmful to their status, we will want to know that piece of information. This is exactly the human nature. This is what lawyers and authorities should be familiar with. Unfortunately, a few of them fail to grasp it.

2.What speeded up the spread of Martha’s story?

3.What is the last paragraph mainly about?
A. The root of Streisand effect.
B. The influence of Streisand effect.
C. People’s reaction to Streisand effect.
D. Historical examples of Streisand effect.
4.What can be inferred from the passage?
A. Streisand effect benefits most famous people.
B. It’s not a good idea to argue against authorities.
C. The ban on something may have opposite effect.
D. Turning to the law is a perfect way to get one out of trouble.
