In the story of “The crow and the Pitcher” from Aesop’s Fables, a thisty crow (乌鸦)drops stones into a narrow jar to raise the low level of water inside so he can take a drink.
Now scientists have evidence to back up that story. Crows actually do understand how to make water displacement (移位) work to their advantage, experiments show. The results suggest that the birds are, at least in some aspects, as smart as first-graders.
Researchers, led by Sarah Jelbert at the University of Auckland in New Zealand, presented six crows with tubes filled with water. Inside the tubes, a worm or piece of meat on a piece of wood was floating, just out of reach of the crow. In front of the tubes, the researchers arranged several rubber erasers that would sink, and some plastic objects that would float. The crows found out that they could drop the erasers into the tubes in order to raise the water level and get their snack.
However, the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow one to get a snack, the researchers said. Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops; while it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn’t realize this, and most of them went for the wide tube first.
Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in a small amount of water at the bottom.
1.How did the crows get the snack in Sarah’s experiment?
A. By breaking the tube.

2.What does the author mean by “the birds handled awkwardly” in paragraph 4?

B. They dropped objects only into narrow tubes.
C. They were not aware of the snack at first sight.
D. They mostly avoided the easier way to get the snack.
3.What does the text mainly focus on?
A. Stories of Aesop’s Fables.
B. The development of crows.

D. Human-animal communication.
4.What can we learn from the passage?

C. Chimps and children are much smarter than crows.

China will green light Internet medical services conducted by medical institutions as part of a broader push to promote Internet Plus Healthcare, those at a State Council executive meeting chaired by Premier Li Keqiang decided.
Medical institutions will be allowed to provide online diagnostic services for some common and chronic diseases in patients’ follow-up visits to their doctors. The top levels of hospitals will be encouraged to provide online services, including consultations (会诊), reservations and test result inquiries.
As China joins the ranks of middle-income countries, the demand for health services has increased accordingly. Internet Plus Healthcare can help reduce the problem of inaccessible and expensive public health services that have long been a big concern for the general public.
One decision coming out of the meeting says the intelligent review for health insurance will be applied and the one-stop settlement will be advanced. The real-time sharing of prescription and drug retail sales will be explored, as well.
“We must waste no time in pushing forward the measures once the decisions made.” Li said. “In recent years, top-level hospitals in major cities have seen steady increases in the number of patents. Medical bills have become a heavy burden on families and high-end medical resources still fall short of meeting the growing demand of the public.”
To solve the problem, a two-pronged (双管齐下的) approach must be taken. One is to establish medical partnerships to strengthen cooperation between major hospitals and community clinics. The other is to bring forward Internet Plus Healthcare to promote the sharing of quality medical resources.
The government will see to it that long-distance healthcare services cover all county-level hospitals. So more efforts will be made to ensure that high-speed broadband network will be extended to cover medical institutions in urban and rural areas. Dedicated internet access services will be set up to meet the needs for long-distance healthcare services.
1.According to the text, which of the following services won’t a patient enjoy online?
A. Receiving a medical operation.
B. Asking doctors for advice after the test.
C. Several doctors discussion about the disease.
D. Making an appointment with a doctor in advance.
2.Why is the demand for health services increasing in China?
A. The expense of medical care.
B. The recognition of health insurance.
C. The improvement of people’s life quality.
D. The inconvenience of hospital equipment.
3.What does Li mean by saying “We must waste no time in pushing forward the measures”?
A. The bills are impossible to afford.
B. The situations are urgent to improve.
C. The measures are perfectly worked out,
D. The hospitals are unwilling to admit patients.
4.What can be the suitable title for the text?
A. Modern Hospitals
B. Online Healthcare on its Way
C. No More Burden for General People
D. Wide Applications of Internet Service
Fei-Fei Li arrived in the U. S. from China at age 16 with many big dreams. And it took many unusual jobs to help her achieve them. Luckily, she was smart and extremely driven. And today, she’s the director of Stanford University’s artificial intelligence lab.

On January 5th, students in our school visited Robot World, which we saw a great diversity of robot. It was amazed to find those robots could do a great number of things just like real people, including playing chess, playing piano and drawing pictures. What’s more, the robots were in different kinds and shapes, which made us enjoyable. In addition, that excited me most was the show given by a group of robots. They danced just as if they are dancers on the stage. By visiting Robot World, I have learned a lot of about robots, especial about their functions and shapes. The great human wisdom is S0 powerful that it make us feel more comfortable live in the world.
