【题目】While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!

About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.

Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.

While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.

Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

What’s the best title of the passage?

A. NASA is trying its best to help astronauts eat better

B. Astronauts may soon be able to enjoy steaming hot pizza

C. NASA is working on making pizza for common people

D. A 3-D pizza printer has been used to make pizza

【题目】The term, culture shock, describes the anxiety produced when a person moves to a completely new environment. This term expresses the lack of direction, the feeling of not knowing what to do, and not knowing what is appropriate or inappropriate. The feeling of culture shock generally sets in after the first few weeks of coming to a new place.

We can describe culture shock as the physical and emotional discomfort one suffers when coming to live in another country or place. Often, the way that we lived before is not accepted as or considered as normal in the new place. Everything is different, for example, not speaking the language, not knowing how to use banking machines and so forth.

Although one can experience real pain from culture shock, it is also an opportunity for resetting one' s life objectives. It is a great opportunity for learning and acquiring new viewpoints. Culture shock can make one develop a better understanding of oneself.

Culture shock has many stages. The first stage is called the "honeymoon" stage. The new arrival may feel excited as everything is new.

In the second stage, a person may encounter some difficult times in daily life. For example, communication difficulties may occur such as not being understood. There may be feelings of discontent, anger, sadness, and feeling incompetence. This happens when a person is trying to adapt to a new culture. Transition (过渡) between the old methods and those of the new country is a difficult process and takes time to complete.

The third stage is characterized by gaining some understanding of the new culture. One may start to feel a certain psychological balance. The new arrival may start to have a feeling of direction and want to belong.

In the fourth stage, the person realizes that the new culture has good and bad things to offer. The person has a more solid feeling of belonging and starts to set goals for living.

The fifth stage is called the " re-entry shock". This occurs when a return to the

country of origin is made. One may find that things are no longer the same. For example, some of the newly acquired customs are not in use in the old culture.

Many factors (因素) contribute to the length and effects of culture shock. For example, the individual's state of mental health, type of personality, previous experiences, familiarity with the language, and level of education. So the five stages are present at different times and each person has their own way of reacting.

The main purpose of the passage is to________

A. discuss and clarify B. argue and advise

C. introduce and explain D. compare and evaluate
