In a country with few predators（捕食者），    5    （introduce）this species was a disaster.   Over 40 types of birds ended up becoming extinct after these pests ate their eggs and disturbed their    6    （nature）habitats.   One of the few species of flightless birds that still remain is the kiwi，    7    is native to New Zealand and is a symbol（象征）of the country.   It's believed that around 20 of them    8    （kill）by these pests every week.

    9    （drive）crazy by the severe situation， the government will set thousands of traps and even spray（喷洒）poison across some areas using helicopters.   Scientists are also working on using a gene-editing tool to find a way to stop the pests    10    reproducing， although some worry this could have unwanted effects.

【推荐2】Alexander Graham Bell was an influential scientist, engineer and     1    (invent). He was born on March 3, 1847 in Edinburgh, Scotland. He is widely credited with the invention of the first telephone. Bell’s mother and wife    2    (be) both deaf, which had an effect    3    his work.

When he was 23, Bell and his parents moved to Canada. Bell studied the human voice and worked with different schools for    4    deaf. He experimented with sound, working with sound, working with equipment used to send different    5    (message) and record sound. He worked on acoustic telegraphy (声报机) with an electrical designer       6    (name) Thomas Watson.

On February 14, 1876, Bell and Elisha Gray, an American electrical engineer, both filed patents (申请专利) covering the transmission (传送) of sounds telegraphically. Finally, Bell    7    (give) the patent. A few days       8    (late), he succeeded in    9    (get) his telephone to work.

Bell improved the design and by 1886 more than 150,000 people owned telephones in the United States. He once said, “The day will come when the man at the telephone will be able to see the distant person to     10    he is speaking.”

In 1899, when Einstein studied at the Swiss Federal Institute of Technology in Zurich, his tutor was Minkevsky, a mathematician.

Once Einstein asked Minkevsky, “How can     1     person, like me, leave his footprints on the road of life and make an outstanding contribution in the     2     (science) field?” It was a complex question. Minkevsky said he had to think about it carefully before     3     (give) him an answer.

Three days later, Minkevsky told Einstein the answer was coming! He     4     (take)   Einstein towards a building site and there they set foot on the ground newly covered by cement (水泥), which, of course, led to the workers blaming them. Einstein was     5     (confuse), so he asked Minkevsky, “Sir, haven’t you led me the wrong way?”

“Can’t you see?” Minkevsky said. “On the old road surface that has long solidified and in those places which     6     (pass) through by countless steps, you cannot leave your footprints.”

Hearing that, Einstein thought long and nodded     7     (serious). From then on, his creativity was inspired. He said, “I never memorize and consider     8     dictionaries and manuals (手册) contain, for my brain only memorizes those things not     9     (include) in books.” It was in this way     10     Einstein left his deep footprints in the history of science.

Every Monday morning, 73-year-old Li Lanjuan sits in her office,     1    ( receive) patients. Despite being a leading figure in China, Li regards herself as     2    ordinary medical worker.
