While elephants born without tusks (长牙)are not unheard of,they normally form just 2 to 6 percent of the population. However, that is not the case at Mozambique’s Gorongosa National Park, where an astonishing 33 percent of female elephants born after the country’s civil war ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behavior expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivory.
Poole says before the country’s 15-year-long civil war, the 100,000—acre park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivory to help finance weapons (武器)and meat to feed the soldiers. Of the less than 200 survivors, over 50 percent of adult females had no tusks. Therefore, it is not surprising that the park’s tuskless elephant population has grown greatly.
This is not the first time researchers have observed a great change in the population of elephants. At Zambia’s South Luangwa National Park and Lupande Game Management Area, areas which were heavily hunted in the 1970s and 1980s, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published in the African Journal of Ecology found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivory.
The recent ban on ivory in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females, to change the trend.
1.What is the probable cause of the phenomenon mentioned in Paragraph 1 ?
A. Illegal hunting. B. Constant farming.
C. A pure coincidence. D. Natural evolution.
2.Why did people kill so many elephants during the civil war in Mozambique?
A. To get funds by selling ivory. B. To develop new weapons.
C. To provide food for local people. D. To make ivory products.
3.Which of the following had the earliest record on tuskless elephants?
A. Gorongonsa National Park. B. South Luangwa National Park.
C. The Ruaha National Park. D. Lupande Game Management Area.
4.What does the underlined phrase “the trend”in the last paragraph refer to?
A. Elephants facing greater danger.
B. Elephants growing more slowly.
C. Fewer female elephants staying alive.
D. More female elephants being tuskless.

It goes without saying, but bears repeating, there are too many cats and dogs without homes. While there are countless shelters and rescue centers that exist, some potential pet owners look to pet shops to find their furry friends. All too often, however, these animals come from puppy and kitten mills (繁殖场) that treat the creatures in cruel ways. San Francisco, however, is doing their part to stop this abuse with pet store adoption. Officials recently voted to ban the sale of non-rescue dogs and cats in local shops.
The effect is two-fold. One, it will stop the popularity of the large-scale mills, which are famous for the miserable conditions cats and does are kept in. Two, it will help facilitate the adoption of thousands of animals that are waiting for their forever homes in San Francisco shelters. District 4 Supervisor Katy Tang, who serves on the San Francisco Board of Supervisors, supported law-making on the ban. “Dogs and cats sold in pet stores often come from inhumane puppy and kitten mills that treat animals with no regard for their health or well-being”, she wrote on Facebook. In her message, she also called on the U. S. Agriculture Department to reinstate information on its website that documents these types of animal cruelty cases—it was removed earlier this month.
San Francisco’s law-making is a victory for those concerned about animal rights, and they aren’t the first city to pass this type of measure. Los Angeles, San Diego, Chicago, Philadelphia, Boston, and Austin also have similar laws in place, with hopefully more places to follow suit.
1.What happened to some dogs and cats before they got in the pet stores?
A. They were treated cruelly.
B. They were abandoned in streets.
C. They received warm welcome.
D. They were raised in shelters and rescue centers.
2.Which of the following may Katy Tang agree with most?
A. People should adopt the dogs and cats.
B. Animals are too cruel to humans being.
C. Government can choose to kill all the dogs and cats.
D. It is not right to ban the sale of non-rescue dogs and cats in local shops.
3.What does the underlined word “reinstate” in Paragraph 2 mean?
A. update B. replace
C. post again D. download
4.What does the last paragraph mainly focus on?
A. No Chinese city joins this type of movement.
B. San Francisco is the last city to ban pet stores.
C. Americans care about animals more than humans.
D. More and more cities are involved in animal rights.

(共15小题,每小题2分,满分30分)
Elephants are trained, at an early age, not to escape. One leg of a baby elephant is tied with a rope to a wooden post planted in the ground. The rope limits the baby elephant to an area determined by the length of the rope. At first the baby elephant tries to break free from the rope, but the rope is too strong. Soon the elephant learns that he cannot break the rope in any case. This space defined by the rope becomes the elephant's comfort zone.
As the elephant grows up it could easily break the rope, but it does not even try because it was conditioned as a baby to think that it still could not break free. As a result, the large elephant remains tied and stays in a small space.
This metaphor(隐喻) can be used to describe what happens to human beings as we become trapped in a comfort zone. Just as the elephant's space determines what it can do, our comfort zone determines what we are able to achieve. Fortunately, humans are born with the ability to make conscious choices. The elephant doesn't try to break the rope free while we can easily leave our comfort zone.
In order to expand our potential and succeed in life, we must expand our comfort zone into unfamiliar fields. You will never realize what you are truly able to achieve if you remain in your comfort zone.
1. The area where the baby elephant can move around is decided by ________.
A. the space covered by the elephant
B. the length of the rope
C. the elephant’s comfort zone
D. the wooden post planted in the ground
2.The large elephant does not try to break the rope, because ________.
A. the rope is too strong
B. a wooden post is planted in the ground
C. the elephant likes the small space
D. the elephant thinks it still could not break free
3. What can be the best title for the text?
A. How to train elephants
B. A cautious elephant
C. A comfort zone
D. Expand your comfort zone

Tips to create great readers
Great readers are made; they are not born. After all, children don’t enter the world knowing how to understand a text or make inferences. 1.Here are some tips for making children great readers by habit.
2.The most important moment in reading instruction is when a student gets something wrong. If the student continues practicing the skill incorrectly, he or she will build weaker habits. Intervene (干预) with a targeted question, such as “How does this part of the text help you understand this character?” Doing so can prevent poor habits from taking root and build great ones in their place.
Build great reading and writing skills hand in hand. Just like adults, students use writing to gather their thoughts about a text and communicate their ideas to others. 3.For example, students can have a discussion about what they’re reading by answering a focus question in writing: “What is the author trying to teach us in this story?”4.By doing this, you can get a better understanding of what guidance the students will need during the discussion.
Make sure students are reading. Independent reading time is important for any reading program. It’s a chance for students to put together everything they’ve learned in reading lessons and fly using their own wings. 5.Providing a rich class library and letting students know that they are expected to read for the entire period will ensure their success as lifelong independent readers.
A. Build habits at the moment of error.
B. Make sure students fall in love with reading.
C. Then, you can review their written responses.
D. They grow into great readers by learning great habits.
E. But it only works if they really do spend that time reading.
F. Specific lines or phrases from the text help to reveal that information.
G. Therefore, you can develop their writing and reading skills at the same time.
