1、Unit 6 Nature in words课时作业(十八)Unit 6Section Developing ideas & Presenting ideas.阅读理解AIt is a question that has long puzzled scientistsexactly why are tigers orange? One might think it makes them more obviousparticularly against a leafy green forest background. William Blake summed it up in his famou
2、s poem known by generations of schoolchildren：“Tyger, tyger, burning bright. In the forest of the night.” But now the answer is at hand.While obvious to us, computer simulations (模拟) of what the big cats look to the main animals they hunt for, deer, show a different picture. Humans with normal colou
3、r vision, can see red, blue and green colours. But deer can only pick up blue and green light; they are effectively colourblind to the colour red, like some humans. It means the tigers orange colouration looks green to them, allowing them to mix perfectly into the background, new research claims.Dr
4、John Fennell at the University of Bristol and colleagues said that they used computers to estimate how noticeable a given animal was. They did this by using images of the environment in which the animal lives, and then creating images to see whether the camouflage helps the animal to mix in.Dr Fenne
5、ll writes that by simulating what the world looks like to animals who are “twocolour vision”someone who cannot discover the difference between red and green“we also identify the most suitable colours for hiding and visibility”Dr Fennell writes in the Royal Society Journal Inter Face：“Considering the
6、 coat of a tiger, it has fur that appears orange to a threecolour vision observer rather than some shade of green, though the latter should be more appropriate colour for an attack hunter in forests. However, when viewed as a twocolour vision observer, the tigers colour is very effective.”The questi
7、on then arises as to why tigers dont grow green coats. Dr Fennell and colleagues write that mammals (哺乳动物) are not able to produce green fur. To do so would “require a significant change to mammalian biochemistry”. There is only one mammal known to have green fur but this is achieved through what mi

10、tigers sometimes cheats people.BGetting green may prevent tigers from being extinct.CThere are no mammals with real green fur in the world.DThe tigers fur will probably evolve into green in the future.BThe term “to extend an olive (橄榄) branch” means to make an offer of peace or reconciliation(和解). T
11、his term has Biblical(圣经的)origins, coming from the section of the Old Testament that deals with the flood; the sign that the flood is over is an olive branch brought back to the ark (方舟) by a dove. Olive branches were also symbols of peace in Ancient Greece and Rome, and they continue to be used in
12、various works of art that are meant to suggest peace.Some people have suggested that the olive branch is a very deliberate and wellconsidered choice as a metaphor(隐喻)for peace, because olive trees famously take years to mature. War is typically very hard on the trees because people cannot take the t
13、ime to nurture them and plant new ones. Therefore, the offer of an olive branch would suggest that someone is tired of war, whether it is an actual war or a falling out between friends.In Ancient Greek and Roman times, people would offer actual olive branches. In Rome, for example, defeated armies t
14、raditionally carried olive branches to indicate that they were giving in, and the Greeks used them into weddings and other ceremonies. In the modern era, the branch is usually metaphorical, rather than actual, not least because the plants can be a bit difficult to obtain.Many people agree that peace
15、 negotiations at all levels of society are a good idea. Between nations, obviously, it is important to extend an olive branch to ensure mutual safety and to help the world run more smoothly. This act can also be important on a personal level, as resolving conflict and learning to get along with othe
16、rs are viewed as important life skills in many cultures.At some point in their lives, many people will be advised to extend an olive branch to settle a dispute or resolve an issue. Some people believe that it takes an immense amount of courage to take this action, as it often comes with an admission
17、 of wrongdoing and regret.5According to the Bible, _.Aan olive branch suggests flood is comingBthe ark is made of olive tree woodCan olive branch means flood is overDa dove loves to settle on the olive branch6The olive branch is considered a good choice as a metaphor for peace for the following reas

20、ill in many culturesCTo me, Shakespeare is a bit of a touchy subject in the theatre industry. I believe Shakespeares plays to be the most challenging in terms of language. When you have challenging language, then understanding the plot and topics discussed becomes a challenge as well. Its like a cha
21、in. If you dont understand it from the start, it makes things hard later on and people tend to give up on it. Regardless of all of this, I believe Shakespeares plays are important in the sense that they are where true theatre started. William Shakespeare is a name everyone knows regardless of whethe
22、r you enjoy his work or not.Many high schools or colleges do at least one Shakespeares play every few years and I like that. I think its important to expose students to plays that are a bit more challenging than theyre used to. Of course, its not easy to understand these plays but then think about t
23、he people who act in those plays. When acting, you have to understand your character inside and out and not only that, but you need to completely know everything going on around you as well. So to understand the script is one thing, but then to take it to that next level in terms of acting in a Shak
24、espeares play is a whole other thing. How about memorizing the lines? Thats one of the hardest things actors have said they had to get through. It is such heightened language that its almost like learning a foreign language. Shakespeares play is tough and thats what I think I love about it the most.
25、 The challenge is understanding. Once you have that then you have room to play with it.Therefore, if people walked into a Shakespeares play with more of an open mind, their experience would be so much better. There is an immense amount of exploration and discovery in his plays and the experience can
26、 be really satisfying.
