Rob is a commercial diver in Louisiana. He performs _______ repairs on facilities. Below is an e-mail he sent to his sister.

Hi Sue,

I know you've been feeling _________ lately about your job, so I thought I would share my _________with you to make you realize it's not so _______　 after all.

As you know, I _________ a diving suit to the sea. This time of year the water is quite cool. To keep water_________, we have a powered water heater which sucks the sea water and _________ it to a delightful temperature. It then _________ the water down to the diver through a hose (软管). Now, this all sounds like a good plan, and I've used it several times with no ___________

This time the water heater____________my whole suit with warm water. It's fantastic… it's like working in a bathtub. But __________ , my bottom started to itch and I scratched it. Within a few seconds my bottom started to feel a fierce burning. I __________ the hose out from my back, thinking that maybe the water was too hot, but the____________ was done. The hot water machine had sucked up a jellyfish (水母) and pumped it __________ into my suit. All of its poisonous, sharp pain-causing tentacles (触须) went into the narrow opening of my bottom!

I informed the dive director of what happened over the communicator. His ____________ were unclear due to the fact that he, along with five other divers, was all laughing heartily. Needless to say I __________ the dive. When I arrived at the surface, the director, with tears of ____________ running down his face, handed me a tube of cream and told me to ____________ it on my bottom. The cream ____________ the fire, but I couldn’t go to the toilet for two days because my bottom was swollen shut.

So, next time you're having a bad day at work, think about how much worse it would be if you had a __________push up your bottom. Whenever you have a bad day, ask yourself, is this a jellyfish bad day?

If a diver surfaces too quickly, he may suffer the bends. Nitrogen(氮) dissolved(溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡)accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.

Other air-breathing animals also suffer this decompression(减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石)bones that have caved in on them selves are thus a sign that the animal once had the bends.

Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.

When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen(标本) showed evidence of that sort of injury.

If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.

Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey(猎物) as well as predator—and often had to make a speedy exit as a result.

1.Which of the following is a typical symptom of the bends?

A. A twisted body.　　 B. A gradual decrease in blood supply.

C. A sudden release of nitrogen in blood.　　 D. A drop in blood pressure.

2.The purpose of Rothschild’s study is to see________ .

A. how often ichthyosaurs caught the bends　　 B. how ichthyosaurs adapted to decompression

C. why ichthyosaurs bent their bodies　　 D. when ichthyosaurs broke their bones

3.Rothschild’sfindingstatedinParagraph4 .

A. confirmed his assumption　　 B. speeded up his research process

C. disagreed with his assumption　　 D. changed his research objectives

4.Rothschild might have concluded that ichthyosaurs.

A. failed to evolve an anti decompression means

Chinese researchers have developed a robot designed to help doctors treat the new coronavirus and other highly infectious diseases. The machine has a long robotic arm attached to a base with wheels. It can perform some of the same medical examination tasks as doctors. For example, the device can perform ultrasounds (超声波扫描检查), collect fluid samples from a person’s mouth and listen to sounds made by a patient’s organs. Cameras record the robot’s activities, which are controlled remotely so doctors can avoid coming in close contact with infected patients. Doctors and other medical workers can operate the machine in another place.

The robot’s main designer Zheng Gangtie, an engineer and professor at China’s Tsinghua University, told Reuters news agency that he got the idea for the device when his medical friend told him that one of the biggest problems in dealing with COVID-19 was that healthcare workers treating patients were getting infected themselves. Zheng said he wanted to do something to help this situation. So the engineer gathered a team and went to work on the robotic device.

Zheng said the devices use the same technology that is used for space equipment, including moon explorers. The new robot is almost completely automated. It can even disinfect itself after performing actions involving patient contact.

However, Zheng said he had heard from some doctors that it would be better not to build such robots to be fully automatic. This is because many patients still desire a personal presence to help calm them during treatment.

The team currently has two robots and both have been tested by doctors at hospitals in Beijing. One machine was taken to Wuhan’s Union Hospital, where doctors there got trained to use it. The plan is to use the robot to help treat coronavirus patients, along with assistance from nurses and other hospital workers.

Zheng would like to build more of the robots, but says money from the university has run out. Each robot costs about $72,000 to make. He says he does not plan to commercialize the design, but hopes that a company can begin that process.

1.What do we know about the newly-invented robot?

A.It is used for space exploration.

B.It completely operates on its own.

C.It carries out complicated surgical treatments.

D.It protects doctors from risky contact with patients.

2.Which of the following may accelerate the development of the machine?

A.Assistance of AI. B.Financial support.

C.Community help. D.Professional advice.

3.What can we infer from the last three paragraphs?

A.The device may not be welcomed by all patients.

B.The device has been widely used to treat patients.

C.Zheng has received further funds from companies.

D.Zheng continued the production for official support.

4.What is the best title for the passage?

A.Promising Future for the Robot

B.Novel Device to Cure Coronavirus

C.New Assistant to Fight Coronavirus

D.Helpful Design to Save the Patients

Reese is actively involved in children’s and women’s advocacy organization.She is a longtime supporter of Save the Children,an organization that helps provide children around the world with education, health care and emergency aid.

1.Why did Reese stop her studies at Stanford University?

A. Because she starred in two successful films.

B. Because she was more famous in Hollywood.

C. Because she didn’t want to get higher education.

D. Because she couldn’t balance studies and acting.

2.Which film made Reese most famous?

A. Man in the Moon　　 B. Legally Blonde

C. A Far Off Place　　 D. Jack the Bear
