We humans are a curious species． As NASA says on its website，"Humans are driven to explore the unknown， discover new worlds， push the boundaries of our scientific and technical limits，and then push further． "
And space exploration is where we\e been "pushing" our furthest curiosity．
The year 2019 began with two pieces of exciting space exploration news． On Jan． 3， China landed a spacecraft，Chang′e 4，on the moon's far side﹣the side we can′t see from Earth﹣for the first time in human history． And according to a report published on Jan． 9 in Nature， scientists from the Canadian Hydrogen Intensity Mapping Experiment （CHIME） detected repeated radio signals from a galaxy 1.5 billion light years away， possibly sent by intelligent aliens．
However， what，s even more exciting than the news is the fact that whenever speaking of space exploration， we forget our political and cultural differences﹣the things that so obsess us．
"When you go into space， you become part of this overall collective （集体）called ‘humanity， Ken Liu， Chinese﹣American sci﹣fi writer and translator，told Quartz website． "You′re no longer Chinese， American， Russian …Your culture is left behind． You're now just ‘humanity' with a capital ‘H'． "
This magic has worked all the way along our journey into space． When US astronaut Neil Armstrong （1930﹣2012）became the first human to set foot on the moon in 1969， for example，he told the world： "That's one small step for man， one giant leap for mankind， "Now， with Chang'e 4 touching down on new moon territory， China′s aim is to help scientists from around the world find out more about Earth's only satellite． And with the discovery of the CHIME astronomers， we ' re one step closer to answering a common question in science： "Are humans alone in the universe？"
It's true that we are a curious species． But instead of being curious about the "unknown"， perhaps we're really more eager to "push further" our own human "boundaries" and "limits"．
1.Which of the following is the discovery of the CHIME scientists？
A. A galaxy with intelligent aliens．
B. Repeated radio signals sent by intelligent aliens．
C. Repeated radio signals from a distant galaxy．
D. Radio signals from a galaxy several years ago．
2.Why does the author quote Ken Liu's words ？
A. To introduce the famous writer， Ken Liu．
B. To show that in space we are just humanity．
C. To emphasize that culture is not important．
D. To introduce the things that obsess us very much．
3.What does the author intend to do in paragraph 6？
A. Further confirm his opinion．
B. Add some background information．
C. Summarize the previous paragraphs．
D. Introduce a new topic for discussion．
4.What's the main idea of the text？
A. China takes the lead in space exploration．
B. Humans are not alone in the universe．
C. Space exploration is a common cause of mankind，
D. Humans desire to push the boundaries of scientific limits．

That the success of humans as a species depends to a large extent on our ability to cooperate in groups is widely believed. Much more so than any other animal, people are able to coordinate and join their forces and actions to produce mutual benefits.
New research involving Dr Molleman, an expert at the University of Nottingham, suggests that successful cooperation in groups depends on how people gather information about their peers, and how they base their cooperative decisions on it.
Biologists wonder how cooperation could have developed by natural selection: it is puzzling how cooperation can be beneficial when it is possible to behave selfishly and take advantage of the cooperative efforts of your group. Psychologists and economists try hard to understand why many people are willing to sacrifice their own welfare to benefit their social environment. They asked questions like “How do people make decisions when their actions can affect the welfare of others?” “How people determine their behavior when they have to cooperate in groups?”.
Dr Pieter Van Den Berg from the University of Groningen said, “From previous research we know that some people are ‘majority-oriented (以……为中心)’ and tend to look at the behavior of the majority in their group, whereas others are ‘success-oriented’ and try to find out what kind of behavior pays off best for themselves.”
Dr Molleman, from the center of the Decision Research and Experimental Economics, said, “It turns out that behavior in groups of success-oriented people was much more selfish than it in groups of majority-oriented people. As a consequence, the people in the majority-oriented groups tended to cam more money in the experiment since they cooperated more.”
1.Compared with other animals, human beings are capable of ________.
A. communicating well with others B. working together with each other
C. surviving some natural disasters D. getting access to various information
2.What are the psychologists and economists most interested in?
A. Whether people’s personal efforts will pay off eventually.
B. How cooperation has developed over a long lime naturally.
C. Why people offer to affect those around them unselfishly.
D. What benefit that good cooperation can bring immediately.
3.We can infer that the success-oriented people________.
A. are careful to select a group to join
B. are likely to be successful in the future
C. pay more attention to the result of their effort
D. have some skills in collecting useful information
4.What is the new finding of the research?
A. Having good relationship gets us to live fullest life.
B. Focusing on individual success makes people selfish.
C. Being considerate can ensure our long-term benefit.
D. Mastering social skills help create harmonious society.

We humans are sweet on sugar. That makes sense. All animals need sugar to live. It ' s the fuel that powers our cells. So it' s not surprising that we ' re born to want the sweet stuff.
Sugar stores the sun' s energy like a battery. After a meal,your body breaks down foods into their building blocks. It uses some sugars for energy right away. The rest get stored for the body to break down later. It ' s a myth that sugar makes you extremely excited, but having a sugary snack can give you a quick burst of energy. That ' s because the sugars in sweet foods are easy for your body to turn into fuel. When you eat other kinds of foods,like vegetables, it takes longer for your body to break the sugars down.
These days it' s easy to find sweet snacks. Sodas, candy, cakes and even foods that seem healthy , such as yogurt,can be packed with sugar. Food makers add sugar,because they know that to humans, sweet makes everything taste better. Americans eat about 20 teaspoons of extra sugar everyday. That' s way more than what is good for us.
Eating too much sugar can cause more than a stomach-ache. It can make people overweight, decay the teeth and even cause diabetes. However, experts aren ' t worried about naturally sweet foods- the problem is added sugar. So go ahead and enjoy a sweet apple or even a sugar-rich carrot that are also full of vitamins and other good stuff.
Even cake is great once in a while , as long as you don ' t overdo it. After all, no one wants life to be dull. And your body needs its fuel!
1.The first two paragraphs are mainly developed by _'
A. cause and effect. B. problem and solution.
C. giving examples . D. making comparisons.
2.People may be tncked into eating too much sugar because .
A. no one wants life to be boring.
B. we ' re born to want the sweet stuff.
C. so-called healthy food can be packed with sugar.
D. sugar is the fuel for the plants and animals on the Earth.
3.What does the author want to stress in Para. 4?
A. We' d better say no to sweet foods.
B. Experts are worried about added sugar.
C. Eating too much sugar is bad for our health.
D. We ' d better consume sugar from natural sources.
4.What can be a suitable title for the text?
A. Sugar Is Everywhere. B. Sugar Brings Happiness.
C. Why Does Sugar Taste So good? D. Why Does Sugar Make Us Fat?
