2、ce, Peter Ungar of the University of Arkansas and his partner, Matt Sponheimer of the University of Colorado, US, examined the teeth of ancient human beings to find out what they were really eating.They already knew that different foods cause different marks on teeth. Some cause scratches, while oth
3、ers cause pits(坑). The carbon left on teeth by different foods is also different. Tropical grasses, for example, leave one kind of carbon, but trees and bushes leave another kind because they photosynthesize(进行光合作用) differently.Traditionally, scientists had looked at the size and shape of teeth and
4、skulls(头骨) to figure out what early humans ate. Big flat teeth were taken to be signs that they ate nuts and seeds, while hard and sharp teeth seemed good for cutting meat and leaves. But this was proved wrong.The best example was the Paranthropus(傍人属类人猿), one of our close cousins, some of whom live
5、d in eastern Africa. Scientists used to believe that they ate nuts, fruits and seeds because they had big crests(突起) on their skulls, suggesting that they had large chewing muscles and big teeth. If this had been true, their teeth should have been covered with pits like the surface of the moon. They
6、 would also have had a particular type of carbon on their teeth that typically comes from tree products, such as nuts and seeds.However, when the two scientists studied the Paranthropus, it turned out to have none of these characteristics. The teeth had a different kind of carbon, and were covered w
7、ith scratches, not pits. This suggested they probably ate grass, not nuts and seeds. It was the exact opposite of what people had expected to find.Carbon “footprints” give us a completely new and different understanding of what different species ate and the different environments they lived in. If a
8、 certain species had the kind of carbon on its teeth that came from grasses, it probably lived on tropical grassland, for example.()1. The underlined sentence in Paragraph 1 probably means that anthropologists can .A. know the structure of human stomachs by studying their teethB. find out the diet o
9、f early humans by studying their teethC. learn whether humans were healthy by looking at their teethD. get the most useful information about humans from their teeth()2. According to Paragraphs 35, which of the following statements is TRUE?A. Pits on teeth are caused by eating grass or leaves.B. Scra
10、tches on teeth are caused by eating nuts or seeds.C. Different foods leave different marks and carbon on teeth.D. Early humans with hard and sharp teeth ate meat and leaves.()3. The example of the Paranthropus was mentioned in order to tell us .A. they were one of our close cousins living in eastern
11、 AfricaB. living environment makes a difference to skull structureC. they had different eating habits from other humansD. the size and shape of teeth dont show accurately what early humans ate()4. Which of the following structures shows the best organization of the article?CP: Central PointPara.: Pa
12、ragraphP: PointSp: Sub-point(次要点)C: ConclusionABCDBDeception(骗术) is something that people do all the time, and it plays an important role in military(军事的) strategy. Now some researchers are trying to figure out how to get robots to do it by looking at the behavior of squirrels and birds.At Georgia T
13、ech, a team led by Ronald Arkin, a professor at the School of Interactive Computing, studied the literature on squirrels hiding their acorns(橡果). Squirrels will hide their food in a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by runnin
14、g to a false location.Ronald Arkin and his PhD student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a “predator(捕食者)” machine by doing what a squirrel does: showing the enemy a false location for an important resource.The team also looked at how other
15、animalsin this case, a species of bird called Arabian babblerdrive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping(拍打) wings and making noises. The babblers do
16、nt ever actually fight the animal they want to drive off; they just make enough noises and flaps around enough so that it seems that attacking a babbler isnt worth it.They found that the deception works when the group reaches a certain sizeessentially, when enough birds arrive to convince the enemy
17、that its best to back off. Davis modeled that behavior in software using a military scene and found that it worked even if the group didnt have the firepower to confront the enemy directly.The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead
18、an enemy down a false trail or make itself look more dangerous than it actually is.()5. Why does the military want to take advantage of squirrels trick?A. It can reduce the use of firepower to confront the enemy.B. It can fool the enemy into believing it is more dangerous.C. It can lead the enemy in
19、 a wrong direction to avoid losing resources.D. It can scare the enemy away who wants to destroy the acorns.()6. Which of the following is NOT the way Arabian babblers drive off predators?A. One bird makes an alarm call and other birds will join it.B. They fight the enemy bravely face to face.C. The
20、y make noises and flaps around the predator.D. They force the predator aware that it isnt worthwhile to attack.()7. What is the main idea of the passage?A. Animals behaviors are researched to be applied to the study of military robots.B. Robots fooling tricks are applied to the study of animals beha
21、viors.C. Birds and squirrels are the animals that are good at deception.D. Researchers are interested in animals military-related behaviors.二、 任务型阅读请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意:每个空格只填1个单词。There are many destructive(破坏性的) forces when it comes to nature, which have destroyed whole cities
22、and killed many people. Theyre really terrible, but they occur somewhat often, and this is why you see so many charities these days which focus their efforts on helping people who have been affected by natural disasters.While the world is a very beautiful place to live in, there will always be parts
23、 of the world where natural disasters happen more often than in other places, where properties and lives are destroyed. Only the people who live in the country where tsunamis and earthquakes as well as other disasters occur experience these, and we can only imagine the suffering that they go through
24、.For some people out there, the world is cruel, but they have no choice but to stay where they are. A lot of the time people simply cannot afford to move away, as they might not be able to get a job when they leave.In 2004, there was a tsunami in the Indian Ocean. A tsunami is a large wave that towe
25、rs hundreds of feet into the air, and covers whole areas when it comes crashing down on to dry land. This particular tsunami was caused by an earthquake that happened in the middle of the sea, shooting the water away from the ground and towards dry land. This tsunami actually reached thirty meters i

This hurricane was known as hurricane Katrina, and is perhaps the worst in the history of the world. It happened in 20
27、05 and destroyed millions of properties in the area. It also took the lives of nearly 2,000 American people. It was known that for ten days, the wind swept through the area, meaning the most powerful country in the world became helpless in their attempts to save the people who were affected by the h
28、urricane.Finally, in 2008 we saw yet another natural disaster. This time it was a cyclone(旋风), which is similar to a hurricane but happens in a circular motion(圆周运动). This cyclone Nargis had been one of the strongest to have ever occurred, reaching a death toll of nearly 150,000 people.All of these

Xiao Ming was sleeping soundly in the sofa， with the TV on， when his mo
34、ther came and turned it off for him， blaming him for not having turned off the TV again.This is often the case in our daily life. Many people are used to doing everything with the TV on， not actually watching it at all. Such a habit can cause a waste of much energy， and do harm to our environment.To
35、 have an eco-friendly life， we must first strengthen the sense of energy-saving and environment protection and popularize the idea of energy-saving life from every detail in our daily life. I think only in this way， can we help to reach harmony of the development of the society and health of the nature.
