Question

阅读理解 　　People have long thought that dinosaurs were brown or gray in color．To examine is one important way to find out the answer．The word“examine”is to look at or consider something in detail in order to discover something about them．After examining the remains(遗骸)of a dinosaur, scientists say they have found evidence it had bright-coloured feathers．The findings were printed in Science magazine． 　　American and Chinese scientists did careful research and re-built the feathers of a flightless dinosaur．The small, two-legged creature(生物)lived about one hundred-fifty million years ago．It would have weighed only about one hundred ten grams．The dinosaur's remains were discovered in Liaoning Province in China．Researchers studied melanosomes(黑素体)in the feathers．These melanosomes are small, color-producing things, and they formed as the dinosaur was developing．The researchers compared them to the melanosomes that control the colour of feathers on modern birds．They were then able to make out the colors of the dinosaur feathers．The dinosaur appeared to have a dark gray or black body．The top of the creature was light brown in color．And, it had bright white wings．Each of the feathers had black on the end． 　　Richard Prum, a biologist at Yale University, says the melanosomes were in very good condition．He says the dinosaur would be a beautiful creature if it were still alive． 　　The discovery is useful to scientists in another way．It helps them better understand not only how dinosaurs looked but also how they lived in their daily life．Some researchers plan to use this way to study the colours of other feathered dinosaurs． (1) What have scientists discovered recently? [　　] A． Brown and gray dinosaurs． B． The first remains of a dinosaur． C． The magazine Science failed to come out． D． A kind of dinosaur with bright-coloured feathers． (2) A flightless dinosaur means that the creature ________． [　　] A． was able to fly B． could have no wings C． could not fly D． was unable to walk (3) Where were the remains of the two-legged creature found? [　　] A． It would have weighed only about one hundred ten grams． B． They were discovered in Liaoning Province in China． C． It lived about one hundred-fifty million years ago． D． They were rebuilt by American and Chinese researchers． (4) The researchers compared ________ of the dinosaur to those of modern birds． [　　] A． the white wings B． the legs and the body C． the melanosomes in the feathers D． the living conditions (5) Which of the following is NOT TRUE according to the passage?The discovery helps scientists ________． [　　] A． to change colours of modern birds B． know how the dinosaurs lived in their daily life C． to study the colours of other feathered dinosaurs D． understand how dinosaurs looked in the old times
