题目内容

China started late in network technologies and has lagged behind for years. With the rapid development of wireless technologies, the concept of the Fifth Generation (5G) mobile communication system started to emerge(出现). Although the development of 5G network technology in the international community is still in the research stage, a number of foreign countries and organizations are working on it. In order to catch up with the pace of the times, China also needs to have its own place in such a competitive environment.

Compared with 2G, 3G and 4G, 5G is not independent and brand-new. It is a combination and further development of present mobile communication technology. Besides the speed upgrade, 5G will also meet the requirements of large bandwidth, super high capacity, super dense site, super high reliability and whenever and wherever possible assess.

There are some rapid changes in China’s telecom space. With the 3G network now widely used, and 4G just around the corner, China is now preparing to enter the 5G era. China has started research and development on the 5G network, and plan to launch the network testing by around 2020. It’s expected that a unified standard will be adopted globally with the 5G technology.

"Under a same standard, different enterprises can be connected, and form a competition environment. Therefore, we can guarantee that enterprises can gain reasonable profits, and at the same time provide faster, better, more convenient and cheaper services to consumers." Wu Ku, Director of Dept. of Science & Tech., MIIT said.

Wu Hequan from Chinese academy of engineering said, "5G will make it possible to connect one million devices to the so-called Internet of Things within one square meter. In the future, it will also be available on high-speed trains moving as fast as 500 kilometers per hour. In the area of the Internet of Vehicles, it can be used in unmanned vehicles, assisted driving and the management of smart cities."

Wu believes China's future Internet will be faster, more intelligent and more reliable.

Chinese government pays more attention to the development of 5G and adopts a more open attitude. With the joint effort of the industry, China will play an increasing important role in the global 5G development.

1.】The first paragraph mainly wants to tell us ____________.

A. the concept of 5G network technology

B. the reason why we need 5G network technology

C. the fact that China fell behind network technology

D. the fact that 5G network technology is good

2.From paragraph 2 and paragraph 3, which kind of network technology is the fastest?

A. 2G B. 3G C. 4G D. 5G

3.What’s Wu’s attitude towards the 5G network technology?

A. Negative. B. Positive.

Scientists found that sleeping considerably improves our creativity. After taking a nap people are able to think faster and put more imagination into their thinking. Besides, if we dream, the thinking abilities are improved even more.

Researchers consider that sleeping on a problem in most cases leads to elucidation(解释). They say when a person enters a phase called Rapid Eye Movement (REM) during sleep, it increases the effect. Such phase takes place right before we awake and according to scientists it helps our brain make links between unrelated subjects.

In the study, led by Professor Sara Mednick, scientists made a conclusion that the REM was “important for assimilating(消化) new information into past experience” in order to find solutions to creative problems.

Prof. Mednick is a psychiatrist at the University of California. Her study involved the analysis of 77 adults. Each participant was given several word-associated creative tasks. All tasks were given in the morning, with participants being shown a number of groups of 3 words, for example: cookie, heart and sixteen. They were asked to come up with a word that would be associated with all three given terms—like sweet. Sometime later, after some participants were allowed to sleep, they were asked to perform the same tasks and some new ones. It is worth mentioning that while some people slept, researchers used brain scans to see the type of sleep each participant entered.

When given the same tasks, participants, who took a nap, were able to give more varied solutions, some of which were much better than they gave earlier. But when given new tasks, researchers found that those who entered REM sleep had a 40 percent better result compared to the performance they showed in the morning.

1.What does “it” refer to in the second paragraph?

A. The effect.B. REM.C. Sleep.D. A problem.

2.Why do the researchers study the REM?

A. Because REM takes place just after you sleep.

B. Because REM can store more information.

C. Because REM can help find creative solutions

D. Because REM can make a creative invention.

3.What can we know from this passage?

A. Taking a short nap is good for your thinking during the day.

B. Sleeping has three processes which is good for creativity.

C. Each adult was allowed to sleep after the task was given.

D. REM is a process taking place right after we awake when we nap.

4.The important stage in the study is________.

A. to think of a creative word

B. to show a group of 3 words

C. to give participants time to think

D. to let some participants sleep for a while

When children start kindergarten, evident gaps in science knowledge already exist between Whites and minorities and between youngsters from upper-income and low-income families. And they often deepen into significant achievement gaps by the end of eighth grade if they are not dealt with during elementary school.

The findings suggest that, in order for the United States to maintain(维持) long-term scientific and economic competitiveness in the world, policymakers need to renew efforts to ensure access(n.使用或见到的机会，权利) to high-quality, early learning experiences in childcare settings, preschools and elementary schools.

The researchers’ study tracked 7,757 children from their start in kindergarten to the end of eighth grade. Researchers found that, among kindergarteners with low levels of general knowledge, 62 percent were struggling in science by the time they reached third grade and 54 percent were struggling in that subject in eighth grade. And general knowledge gaps between minorities and Whites were already large at the time when students began kindergarten.

“Children growing up in low-income families typically experience comparatively fewer early opportunities to learn about the natural and social sciences,” the authors wrote. “Their parents often have lower educational levels and therefore less science knowledge themselves as well as fewer resources available to direct the children’s academic growth. Children raised in poverty often attend poorly resourced schools that futher limit their academic opportunities.”

Morgan said that, within families, parents who regularly talk and interact with toddlers(学步的儿童) can point out and explain physical, natural and social events occurring around them daily. This might help youngsters learn facts and concepts that will prepare them to take better advantage of science instruction they receive during elementary and middle school.

1.Which may be the possible result of the gaps in science knowledge during kindergarten?

A. Children from rich families will behave better in life.

B. Children from minorities may have less desire for learning.

C. Children’s academic performance afterwards will be affected.

D. The gaps will disappear automatically when children grow up.

2.What did the researchers suggest policymakers do?

A. Make superior education available to children.

B. Narrow income gaps between different families.

C. Give extra lessons to children from poor families.

D. Strengthen competitive awareness of kindergarteners.

3.What can parents do to help their toddlers learn?

A. Give them more nutritious food

B. Offer them more learning resources.

C. Let them attend science courses for kids

D. Greate learning opportunities in daily life.

4.Which of the following can be the best title for the text?

A. Income Gaps Affect Children’s School Performances

B. Provide More Available Access to Childhood Learning

C. Science Knowledge Gaps Are Obvious in Kindergarten

D. Equal Education Is Important in Kindergarten

It is well-known that good habits do us good. Entered high school, I took delight in having fast food and often eat too much. In the end, I was so serious overweight that I suffered a lot from my awkward appearance. It made matters worse was the fact that my classmates made a fun of me at times. From now on, I made up my mind to avoiding snacks. In the meanwhile, I took off jogging to lose weight. To my surprise, it was not long until I did succeed in creating my new appearance. Only then I start to appreciate the importance of developing a good habit.
