Today, we have to use     1     (switch) for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners. In the future, we will be using     2     (advance) technology every day for automatic control of just about everything in our home. The future home will use integrated sensors to tell when you leave home each morning, and then go into an energy-efficient mode all     3     itself.

World leaders are planning to return to the moon in the near future. Two companies have also made a decision     1     (support) space travel. They will give 30 million dollars to the first members who send a vehicle to the moon and send video back to Earth over the Internet. In addition to     2     (make) a lot of money, the winners will also make history. In the 1400s, Spanish leaders     3     (give) Columbus money to explore the world; in return, they learned about a whole new part of the world. Today’s lunar explorers are similar. Who knows     4     they will discover?

In the last seven days I have seen the pressure that the NHS is under. I have seen the personal courage not just of the doctors and nurses but of everyone, the cleaners, the       1    (cook), the health care workers of every description-physios, radiographers     2    have kept coming to work, kept putting themselves in harm's way, kept     3    (risk) this deadly virus. It is thanks to that courage, that devotion, that duty and that love that our NHS has been unbeatable.

The Arctic Ocean in summer will very likely be ice free before 2050, at least temporally. The research team     4       (analyze) recent results from 40 different climate models. Using these models, the researchers considered the future evolution of Arctic sea ice cover in a scenario with high future CO2 emissions and little climate protection. As     5    (expect), Arctic sea ice disappeared quickly in summer in these simulations.

However, the new study finds that Arctic summer sea ice also disappears occasionally if CO2 emissions are       6    (rapid) reduced.

In order to understand    7     bird brains changed, a team of 37 scientists used CT scan data to create endocasts(内腔)of hundreds of birds and dinosaurs, which the    8    (combine)with a large existing database of brain measurements from modern birds.

They then analyzed brain-body allometry (体形变). “There is no clear line     9    the brains of advanced dinosaurs and primitive birds,”    10    (note) co-author Dr. Amy Balanoff of Johns Hopkins University." Birds like pigeons have the same brains sizes you would expect for a dinosaur of the same body size, and in fact some species like moa(恐鸟) have smaller-than-expected brains.”

What do top minds from various fields think about     1     life will be like in 30 years? Mathematical biologist Joel Cohen says that the majority of the people in the world will live in urban areas. According to Bill Mitchell, director of MIT’s Smart Cities research group, by 2050 self-driving cars     2     (make) the roads safer, providing more efficient transports. To find out more about the predictions of future life, at nine o'clock tomorrow morning, I     3     (attend) a seminar held by the Future World Forum.

10 . With the development of science and technology, intelligent robots will be widely used in the future. At home, robots will help     1     (we) do some housework and take care of the elderly, babies and parents. In addition to these     2    (task), robots will even be able to play chess and do exercise with people. In factories, robots will be used to perform some dangerous jobs     3    (avoid) accidents. Robots will change our future life in many ways, which will make it more colorful and comfortable. However, we shouldn’t depend on intelligent robots too much, for they     4     (make) to help humans rather than replace us. So robots should be used     5    (proper).
