Humans have launched themselves into the outer space. They've landed on the moon. They've built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet–specifically, Mars.

The problem is that it's no easy task. The planet is 586 times further away from the Earth than the moon, and it'll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).

Here's where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.

Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They're small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.

Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).

This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.

The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.

Results for the 20 experiments are coming in gradually. But it's clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.

In a world where technology is king, hardly does a day go by without the launch of some “world-changing” product in the field of alternate reality. 【小题1】 These include VR, AR, MR, XR and the list goes on.

Many people confuse augmented reality (AR) with virtual reality (VR) and understandably so. Both AR and VR offer alternate or altered reality experiences and as a result, it is easy for users to be attracted and wonder what is real and what is not. 【小题2】 Both aim to provide an enhanced or enriched experience to users, most commonly used in the gaming scene, but also increasingly used in other areas.

However, AR and VR can be quite different in many ways. 【小题3】 Simply put, VR “transports” the user to another world, by “replacing” the real world with a virtual substitute most commonly done through helmets or goggles to completely immerse (使沉浸于) the gamer in a different reality. For example, it can make users feel as if they are falling, thereby igniting fear.

AR, however, does not change the entire landscape of what users see. In fact, it adds to reality with digital images. While AR may be less immersive than VR, the success of games which use AR is proof that it can be just as or even more entertaining than VR games. 【小题4】

VR and AR are both powerful technologies which are still relatively new to many consumers. 【小题5】 They can completely change how we use our electronic devices in the future, but whether one will edge out the other is anyone’s guess.

A.VR can be interactive or non-interactive.
B.The main difference lies in the mode of delivery.
C.In short, at the heart of VR and AR are two very similar technologies.
D.However, they have already begun to shake things up in the gaming world.
E.They would see computer made images as an overlay to what they see in real life.
F.Moreover, since AR does not require the use of goggles or helmets, it is more accessible.
G.It is also getting increasingly difficult to keep up with the “R” s that have come into existence.

Do you have a favorite sport? Are you passionate about sewing or reading? Typically, you engage in these activities simply because you enjoy them. Would you be taken aback to know the overjustification effect that when you are rewarded for your beloved activities, your desire to participate in them diminishes?

Edward Deci, a psychology professor, conducted a series of experiments, in one of which Deci divided the participants into two groups: one was paid to complete a puzzle, and the other was not paid to. After money was removed, the group that was previously paid to play showed less motivation to complete the task than the group that was never paid and only did the puzzle for enjoyment. The outcome demonstrated the overjustification effect, which occurs when an external stimulation decreases a person’s internal motivation to perform a behavior or engage in an activity.

According to the self-determination theory, three conditions are essential for people to feel internally motivated and perform at their best: autonomy, freedom from external restrictions; competence, the need to feel capable, and relatedness, the need to feel connected with others. In Deci’s experiment, money acted as a tie, which reduced participants’ autonomy, a crucial component of internal motivation, discouraging them from experiencing the freedom of external restrictions. The pressure to perform for the money lessened the pleasure and freedom felt by those who were doing the puzzle merely for fun.

But if external stimulation is tied to performance, the overjustification effect is less influential. For example, being rewarded for studying is unlikely to decrease internal motivation because the grade depends upon actually doing well rather than just going through the motions.

While the overjustification effect can reduce motivation, some strategies can lower its impact. One is to focus on providing feedback and recognition rather than concrete rewards. For instance, praising an individual’s effort or acknowledging their accomplishments can maintain their internal motivation. Additionally, allowing individuals to have autonomy and control over their tasks also works. By giving them the freedom to choose how they complete tasks, individuals are more likely to be internally motivated and experience a greater sense of satisfaction and engagement.

【小题1】What does the underlined word “diminishes” in paragraph 1 mean?
A.Remains.B.Weakens.C.Ceases.D.Solidifies.
【小题2】How did Deci prove the overjustification effect in the experiment?
A.By interpreting a concept.
B.By presenting an argument.
C.By making a comparison.
D.By describing a phenomenon.
【小题3】What is mainly illustrated in paragraph 3?
A.The skills needed for a puzzle.
B.The core elements of inner drives.
C.The impact of autonomy on competence.
D.The theoretical basis for the overjustification effect.
【小题4】Which serves as an example of preventing the overjustification effect?
A.Speaking highly of a pupil’s hard work.
B.Rewarding a kid with candy for playing the violin.
C.Offering a clerk financial bonuses for daily routines.
D.Promising an employee a decent position for doing his duty.

There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external result or product that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language -- all these are examples of people who have measurable results to show for their efforts.

By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they encounter new experiences and unexpected obstacles. In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept.

In order to grow, to travel new roads, people need to have a willingness to take risks, to confront the unknown, and to accept the possibility that they may “fail” at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we perceive ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we’re shy and indecisive? Then our sense of timidity can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe. Do we think we’re slow to adapt to change or that we’re not smart enough to cope with a new challenge? Then we are likely to take a more passive role or not try at all.

These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to change and grow. If we do not confront and overcome these internal fears and doubts, if we protect ourselves too much, then we cease to grow. We become trapped inside a shell of our own making.

【小题1】A person is generally believed to achieve personal growth when _____.
A.he has abandoned the habit of idleness
B.he has made great efforts in his work
C.he is keen on learning anything new
D.he has tried to determine where he is on his urgent journey
【小题2】In the author's eyes, one who views personal growth as a process would _____.
A.succeed in getting a high position in society
B.judge his ability to grow from his own achievements
C.face difficulties and take up challenges
D.aim high and reach his goal each time
【小题3】When the author says" a new way of being " in the third paragraph, he is referring to _____.
A.a new approach to experiencing the world
B.a new way of taking risks
C.a new method of holding our ground
D.a new attitude towards our failure
【小题4】For personal growth, the author approves of all the following EXCEPT _____.
A.curiosity about more chances
B.quick adaptation to new conditions
C.open-mindedness to new experiences
D.avoidance of internal fears and doubts
