【題目】
Shanghai University of Engineering Science has become the first university in China to be covered by a 5G network,the university announced on Tuesday.
Chinese mobile carriers(運營商)are expected to spend 1.2 trillion yuan(US$176.5 billion)on 5G by 2025,50 percent more than their total 4G investment(投資),Nomura said yesterday.Carriers including China Mobile,China Telecom and China Unicom,are expected to build over 4.9 million 5G base stations by 2025.
5G is a "game﹣changing" opportunity for carriers as they can explore new business like smart manufacturing,super high definition video and smart driving,instead of just being a "pipeline" for voice and data services.
China will supply "temporary " 5G licenses in several aimed cities this year.Consumers(消費者)will be able to use the first batch of 5G smart﹣phones and tablet computers in the second half.It's the first time that China's top industry regulator clarified the 5G industry timeline,especially the first appearance of 5G phones.
But 5G services will become accessible to normal consumers later than expected.More work needs to be done to make the 5G industry fully developed,which won't happen until 2020,said UBS recently.New business projects and organizations,rather than normal consumers,will enjoy 5G services at first.The first batch of 5G services will be available to consumers in about 10 cities only.
【1】How much did Chinese mobile carriers spend on 4G?
A. About 1.2 trillion yuan.
B. About US$176.5 million.
C. About 0.8 trillion yuan.
D. About US$0.8 billion.
【2】What does the underlined word "accessible" probably mean in Chinese?
A. 易獲得的
B. 困難的
C. 讓人理解的
D. 費解的
【3】Which part of a newspaper may the article come from?
A. Lifestyle.
B. Health.
C. Education.
D. Technology.
【4】What's the main idea of the article?
A. Mobile carriers plan to spend much on 5G and it will come into our life soon.
B. China will supply "temporary"5G licenses in several aimed cities this year.
C. 5G services will become accessible to normal consumers later than expected.
D. The first batch of 5G services will be available to consumers in about 10 cities only.

【題目】
Many environmental groups are warning that oceans of the world are in great danger.In the past 50 years,the number of water with zero oxygen(氧氣)in the open ocean has increased more than four times.In the near coast water bodies,including the river mouth and seas,low﹣oxygen areas have increased more than 10 times since 1950.Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms.To stop the drop,the world needs to control in both climate change and nutrient(養(yǎng)分)pollution.
Oxygen is a must to life in the oceans.The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment.
This is the first time for the scientists to take such a deep look at the causes,results and solutions to low oxygen worldwide,in both the open ocean and the near coast waters.About half of the oxygen on Earth comes from the ocean.However,mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters,where oxygen is too low to support most sea life.
In the areas traditionally called "dead zones", like those in Chesapeake Bay and the Gulf of Mexico,oxygen drops to levels so low that many animals have trouble in breathing and die.As fishes run away from these zones,their living areas become smaller and smaller.But the problem goes far beyond "dead zones".Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death.Low oxygen also can cause the release of dangerous chemicals.Although a few animals can grow well in dead zones,overall biodiversity(多樣性)falls.
【1】How to stop the drop of ocean oxygen in the article?
A. By controlling in both climate change and nutrient pollution around the world.
B. By taking a deep look at the causes, results and solutions to low oxygen worldwide.
C. By running away from these zones, for the living areas become smaller and smaller.
D. By cutting down the number of animals in the oceans.
【2】Why are these waters called"dead zones" from the article?
A. Because the oxygen in these areas is too low for most sea life to live.
B. Because nutrient loading and climate change are greatly increasing.
C. Because there are no animals living in these areas.
D. Because low oxygen also can cause the release of dangerous chemicals.
【3】Which of the following statements is TRUE according to the article?
A. Only a few animals living in the sea need oxygen.
B. Climate change can help cut down the dead zones.
C. Fishes grow faster and better in low oxygen areas.
D. Human activities have many serious effects on ocean environment.
