And recent data from NASA's Curiosity rover（探测器） indicate Mars Crater once held a big lake. This discovery suggests that the red planet may have been much wetter than scientists thought and raises the possibility that the planet was once habitable.“The size of the lake and the length of time and series that water was showing up implies that there may have been enough time for life to develop.” NASA's Mars Exploration Program scientist Dr. Michael Meyer said.Curiosity collected the new data on its five-mile drive to Mount Sharp, the prime destination on its mission to study Mars' climate and geography. The rover landed in Gale Crater in August 2012. After reaching Mount Sharp in September, the rover spent two months studying rocks at the base of the three-mile-high mountain, discovering fine layers of mudstone--which tend to collect at the bottom of lakes. This shows how a mountain inside a Mars' Gale Crater might have formed.“If our assumption for Mount Sharp holds up, it challenges the idea that warm and wet conditions were passing, local, or only underground on Mars,” Dr. Ashwin Vasavada said in a written statement. “A more radical explanation is that Mars' ancient, thicker atmosphere raised temperatures above freezing globally, but so far we don't know how the atmosphere did that.“Vasavada said Curiosity will continue to study changes in the rock 6formation as it climbs Mount Sharp in the next few months, which should test the team's assumption.“We'll also look at the chemistry of the rocks to see if the water that was once present would've been of the kind that could support microbial life(微生物), if it ever was present,“ he said in a video released by NASA. “With only 30 vertical feet of the mountain behind us, we're sure there's a lot more to discover.“29.

Music historians say that Kern gave artistic importance to American popular music for the first time. And, they say, he led the development of the first truly American theater music.Jerome Kern was born into a middle-class family in New York City in 1885. Jerome’s mother, Fanny, loved the piano. She began to teach Jerome how to play when he was very young. He became a fair piano player but not so good that anyone expected him to become a great musician.Jerome was a quiet boy and not a top student. When he completed high school, his father said he would have to work in the family’s store. Mr. Kern said his son could never make money writing music. But he later came to believe that Jerome might do better in music than in business after all. So he let the boy go to Europe to study music, as almost all serious young musicians did at the time.Jerome Kern began his career as a songwriter in theaters in London and New York. Success came quickly. By the early 1920s, Kern was a successful young composer for Broadway musical comedies. In one three-year period alone, he wrote music for 19 shows.Other people wrote the words for Kem’s songs. Kern wrote only the music. 7And he worked with each song until he was satisfied that the music was perfect. He almost never changed his music to fit the words. One of Kern's best-loved songs is “Smoke Gets in Your Eyes,” sung by Dinah Washington.32. Which of the following elements is of little help in Jerome’s success?A. His mother’s influence. B.

Everyone expected him to become a great musician when he was young.B. Not only did Kern write the words for the songs, he also wrote the music.C. There is no possibility that Jerome Kern would change his music to fit the words.D. Kern succeeded shortly after he began his career in theaters in London and New York.35. The passage is mainly talking about .A. Jerome Kem’s daily lifeB. The great contributions made by KernC. Some famous songs written by Kern to usD.

So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen. Here are three tips for great cooking on a tight schedule:1. Think ahead. The moments when I think cooking is a pain are when I’m already hungry and there’s nothing ready to eat. So think ahead of the coming week. When will you have time to cook? Do you have the right materials already? 37．2. Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread? 38． It takes around the same amount of time to make more of something. So save yourself the effort for a future meal.3. 39． This may surprise you, but one of the best tools for making 8cooking worth your time is experimentation. It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule.
