You can see that the “transitions” are more than just a simple word. they are transitions of ideas. create two transition sentences that you might use after each of the introduction samples you read.

1. “we often say we have “sacrificed” when we feel we have given up something. but sacrifice does not necessarily mean “loss.” sacrifice can also mean delaying something in order to gain something else that is worth more than what one gives up. for example, most college students give up time previously spent with friends in order to study. the sacrifice is made for an object greater than momentary pleasure: a degree. the expectation is that the degree will lead to employment opportunities, job satisfaction, and financial security. this kind of sacrifice does not seem so hard when we consider the benefits we’ll receive. but some sacrifices are more difficult. what prompts us to make sacrifices that will not benefit us personally? our moral sense often leads us to make sacrifices that have no apparent benefit, but that satisfy some deep need we have to do what is right.”

2.“throughout the 20th century, our views of life on other planets has drastically changed. it was once thought to be an impossibility, as all we had seen of space showed us a barren landscape unfit for anything we would recognize as life. but, in the 21st century, our telescopes continue to discover planets in what we deem “habitable zones,” the small bands in solar systems in which a planet’s temperature is ideal to support life. planets such as the newly discovered planet koi 172.02 may hold the key to discovering life outside of earth.”
