课时跟踪练(一) Introduction & Reading Pre reading.阅读理解AA home science experiment recently took_the_world_by_storm. Two teens from Toronto, in Canada, sent a Lego man rising above the Earth and captured their tiny astronauts trip on film.Mathew Ho and Asad Muhammad, both 17, used a weather balloon to launch their plastic lego model 16 miles above the Earth. This is inside a part of Earths atmosphere.The two teens were inspired by a similar project performed by students at the Massachusetts Institute of Technology (MIT). The MIT students had launched a weather balloon with a camera into near space and taken many unusual images of the Earth. Mathew and Asad then spent four months figuring out how to launch their own spacecraft into the space.Traveling to space is expensive for NASA, but Mathew and Asad worked hard to keep their costs down. They bought much of their equipment used and even sewed the Lego mans parachute (降落伞) by hand. In total, the project cost only $400.“We had a lot of anxiety on launch day because there were high winds when we were going up,” Mathew told reporters. They had to pump extra helium (氦) into the balloon so that it would rise quickly and avoid being blown too far off course by the strong winds.The toy astronauts journey lasted 97 minutes before the balloon broke and he fell back to Earth. Mathew and Asad then spent two weekends looking for their spacecraft. It had landed 76 miles away from the launch site.The student scientists are currently finishing up their final year of high school and applying for colleges. They are also looking into more doityourself space projects.“I guess the sky is not really the limit anymore,” Mathew told reporters. “We never knew wed get this far. Its been a lesson for us that hard work pays off.”语篇解读:本文主要介绍了两个青少年利用气象气球把他们的玩具乐高人送到太空的过程和结果。1By saying “took the world by storm” in the first paragraph, the writer meant the experiment _.Adestroyed the worldBflooded the worldCfascinated the worldDmanaged the world解析:选C词义猜测题。根据第一段的第二句话可知两个青少年把一个玩具乐高人送入了太空,并把过程拍了下来,因此作者想要表达的是这个试验吸引了世人的目光。2Which of the following about the students at the Massachusetts Institute of Technology (MIT) is right?AThey were examples for Mathew Ho and Asad Muhammad.BThey helped Mathew Ho and Asad Muhammad to achieve dream.CThey launched weather balloon together with Mathew Ho and Asad Muhammad.DThey studied with Mathew Ho and Asad Muhammad in the same school.解析:选A细节理解题。根据文章第三段的第一句话可知选A。3How did Mathew and Asad keep their costs down?ABy sewing the weather balloon themselves.BBy borrowing spacecraft from the MIT students.CBy making their spacecraft by hand.DBy using secondhand equipment.解析:选D细节理解题。结合文章第四段的第二句话可知他们使用二手的设备来节省费用。4What problems did Mathew and Asad have on launch day?AThey ran out of helium.BThe wind was too strong.CThe balloon suddenly broke.DTheir spacecraft was blown away.解析:选B细节理解题。根据文章第五段中的“We had a lot of anxiety on launch day because there were high winds when we were going up”可知,在他们进行发射的那天遇到的问题是风比较大。BHi there, 2060!Children are the future. In 2060, todays children will be parents, grandparents and possibly even greatgrand parents.Those still alive in Valdosta, Georgia in 2060 will be able to share a part of their youth with the youth of the day, when the citys time capsule (时间胶囊) is dug up in Drexel Park.Students from the Valdosta City School System have had a hand in collecting information that will be placed in the time capsule.Kindergarten to the second grade studied transportation. Third through fifth graders looked at the technology of today. Sixth through eighth focused on (关注) music and entertainment. Ninth through 12th graders went to work on fashion and food.Students were asked to make a scrapbook page recording their specific (特定的) area.The high school pages are a wonder of color and design.Many students detail (详述) the food of the moment. Susanna Sin, 16, includes the local restaurants.“People will want to know what was here, and maybe it will be here then,” said Sin, an 11th grader.Sin doubts that much will change in 50 years. Teenagers will still want to hang out with friends, and people will still be searching for the things that make them happy, she said.Education, however, will be completely different, she added. Technology will be even more important in the lives of students in 2060.Katherine Wakeley, 16, said the scrapbook will give the people of 2060 a chance to see what was popular in 2010, especially where fashion is concerned (相关的)“Skinny jeans and rips in your pants are the biggest things,” Wakeley said.The hugely popular Glee television show, as well as teenage superstars Miley Cyrus and the Jonas Brothers, is also mentioned in the scrapbook.Though fashion, music and movies will change, Wakeley doesnt believe that Valdosta will ever let go of its greatest passion football.“Itll still be here,” Wa
