13、项涂黑。A“Im ready.”said Alyssa Carson,a now-17-year-old astronaut-in-training from Baton Rouge,Louisiana.Forher,riding the most aggressive roller coaster in the park is not a big deal.If all goes according to her plans,NASA will send her to Mars in 2033,making her the first human to step foot on the pl
14、anet.She will spendtwo to three years doing something on it,growing food,performing science experiments,and searching forsigns of life.“The Martian is actually very accurate.”she said.“A lot of the things that happened in themovie are similar to what is going to happen.”Shes devoted her entire life
15、to preparing for this journey.Her love for space started when she was 3 years old and watched a cartoon called The Backyardigans.Fiveanimal pals go on imaginary adventures in their backyard including in one part,a mission to Mars.“I thoughtThis red planet is so cool,”she said.“I started watching vid
16、eos of rovers landing on Mars.I had a largemap of Mars in my room I would look at.We started gettingtelescopes so we could look at space.”At 7 her father took her to space camp in Huntsville,Alabama.“That was the weekend of my life,”she said.“I got to learn everything I had been wanting to know and
17、more.I got to see a life-size rocket.”Shecherished the rocket so much that she returned 18 times.At the age of 12 she became the first person inhistory to attend all three NASA space camps in Huntsville,Alabama;Quebec,Canada;and Izmir,Turkey.At first she mastered the basics of space and how humans h
18、ave explored it throughout time.3As she got older she simulated(模拟)missions,trying to reach a destination in gravity-free,weightless zones.When she was 9 she met NASA astronaut Sandra Magnus.The experienced explorer told her she was her agewhen she decided to go to space.At that moment Alyssa knew h
19、er love of space was not a passing hobby.“Idid the same thing as other kids,like switching my mind about careers,wanting to be a teacher or thepresident one day,”she said.“But the way I always thought about it was I would become an astronaut,go toMars,come back,and then be a teacher or the president
20、.”21.Alyssa Carson is great because_.A.she has created model missions to the MarsB.she is the youngest to have completed astronaut trainingC.she is likely to be the first human to perform different tasks on the MarsD.she has visited the space camp in Huntsville,Alabama for nearly 20 times22.NASA ast
21、ronaut Sandra Magnus was mentioned in the last paragraph to stress_.A.the power of space dreamB.the popularity of space travelC.the importance of career choiceD.the excitement of her space experiences23.What is the authors purpose of writing the text?A.To introduce American space industry.B.To promo
22、te the values of American teens.C.To encourage tours to the Mars.D.To present a rising American space star.BIn June,the Oxford English Dictionary,or OED,added about 1,000 words and new definitions to its website.The changes are to help users understand a mix of terms,some dating back many centuries.
23、The additionsinclude words such as“brencheese”“deathshildy”and“hip-pop”.The new entries are part of the companys update to O,its searchable online dictionary for paidmembers.The OED makes changes to the website four times each year.But the latest print version has beenin process since the year 2000,
24、and may not be ready for 10 more years.That information comes from Katherine Connor Martin,who heads the companys dictionary ope rations inthe United States.Usually,the OED watches usage of a word for at least 10 years before deciding whether to add a new entry,4new definition or word related to an
25、existing entry,she said.This general rule,however,is sometimes notfollowed.That is what happened with“tweet”,a word that the OED added far before the 10-year mark.Othertimes,the company adds words that are very old,but were not included in the dictionary in the past.“Its funny because we talk about
26、new words,but many of the words we add are already obsolete.Its justthat they were never in the dictionary before.”Martin told the Associated Press.That is the reality,she said,of a historical dictionary trying to put more than 1,000 years of English intobooks that already have over 855,000 entries.
27、So,you get“brencheese,”a rarely used term for when breadand cheese are eaten together.The word dates back to the year 1665.The word“deathshildy”is from OldEnglish.It means someone who is guilty of a serious crime and condemned to death.The website defines the term“hip-pop”for music that combines par
28、ts of hip-hop and popular music.TheOED discovered the term“hip-hip pop”was used in a 1985 story from a Pennsylvania newspaper.It notedthat the term“hip-pop”appeared in a 1991 U.S.newspaper report about the rap artist M.C.Hammer.The website has added several other terms related to modern culture.They
29、 include three popular terms:“binge-watching,”“spoiler alert”and“microaggression”.Here are a few other new entries if you long to read on.24.What has OED done recently?A.It has made changes to its words explanation.B.It has sorted out some words which are out of date.C.It has helped users to have mo
30、re convenient use of OED.D.It has taken in more words and new meanings of some words.25.The underlined word obsolete in paragraph 4 is closest in meaning to _.A.desertedB.updatedC.changedD.explained26.What will the paragraph following the passage most probably be about?A.The influence cultures have
31、on the words in OED.B.The difficulties OED has in choosing the words.C.The effect modern technology has on OED.D.The new vocabularies OED has included.27.Whats the best title of the text?A.OED,A Great Help for English LearnersB.A Brand New Version of OED WebsiteC.A Better Understanding of Words in O
32、ED5D.Examples of OED Choosing WordsCScientists have long struggled with how to measure the effects of climate change on wildlife.In the past,researchers depended mainly on information gathered by satellite to follow the movement ofbirds and animals.But this method can be costly and result in huge am
33、ounts of information,which can bedifficult to process.Now scientists are turning to another kind of technology to help them follow birds andother wildlife.Songbirds are especially difficult to study in the wild.They can fly across thousands of kilometers and theirbodies are too small for electronic
34、tracking devices.A new report tells about a project in which researchersrecorded songbirds and then put the sounds into a computer program to be studied.The researchers createdmachine learning algorithms(学习演算法)with the ability to focus on bird calls while ignoring other noises.Birds are known to mak
35、e more singing and calling noises after arriving in areas where they plan to mate.Spring is short in extreme northern areas of the American state of Alaska.There,the birds mustmate andhave their young before winter.The algorithm is designed to use the recordings to estimate when the birdsarrive in l
36、arge groups to begin mating.A lead researcher on the project,Ruth Oliver from Columbia University in New York,said that she andothers traveled to northern Alaska to put recording equipment in four different places.The equipment was used to make four half-hour recordings each day.“Theres a lot of oth
37、er noise in these recordings,such as that of wind and rain.”Oliver adds that the machinelearning method is a valuable tool to help identify and process the most useful parts of the recordings.Oliver says the unsupervised machine learning method could be retooled to use sounds to measure themovements
38、 of other wildlife.“This could allow us to track large-scale changes in how animals areresponding to climate change,”she said.Emily Jo Williams is a bird expert.She said she agrees that machine learning can provide scientists withvaluable information about how climate changes are affecting animal po
39、pulations.“We know from some research that some birds ranges have actually changed,and theyve moved inresponse to what we think is a warming climate.”Researchers have also created a machine learning system that they say uses artificial intelligence or AI toidentify,count,and describe the behaviors o

41、ds covered too long a distance for the satellite to follow.C.The amount of information collected is too large to process.D.The amount of information collected is far from accurate.29.Whats the purpose of the machine learning method mentioned in the last paragraph?A.To measure the effect of global wa
