A
When my son was first diagnosed with Autism（自闭症）, it was a very hard time for us . However , in some ways it was a relief , because we finally had a name for what was going on in our lives , but it also meant years more of uncertainty , and we didn’t know what the future held .
When I shared the news with my coworkers , I was so surprised and happy to receive so much immediate love and support from them . They were focused on what we needed , as opposed to how it would affect my ability to make it to work .
One coworker , Jackie , in particular , was amazing to my family and me . She called me into her office a few days later , and gave me a “ worry stone ” . It
gives you some thing to focus on when you’re worried , rubbing your thumb around on this stone . It was a lovely gesture .
She then extended a permanent offer to drive us to any appointments or testing what we needed . Considering the fact that we lived 90 minutes from where most treatments took place , this was a tremendous offer . She made it very clear to me that this offer included last minute trips or emergencies . Anytime we needed to go anywhere , she was willing to be our transportation . She said that we needed to be able to focus on our son instead of having to divide our attention between the road and him .
We never did need to take her up on her wonderful offer , but knowing it was there and that she was so willing to help made it feel like we were much less alone .
36. What does “ a relief ” refer to in the first paragraph ?
A. my son’s recovery from the disease

37. A co-worker offered to drive for us probably because __________ .
A. she is a more experienced driver
B. we live far away from the hospital
C. she lives very close to our house
D. she wishes to reduce our worries
38. What does the writer think of the offer by Jackie ?

B. It’s a last-minute offer .
C. It’s not necessary .
D. It’s a difficult decision for her .

C. In Time of Need
D. A Story of Sacrifice
B
Hero
Carl West is an unassuming（谦逊的）all-American 24 year old . You might think that because he works in a convenience store that he’s not the brightest guy you’re likely to meet . Yet this slightly scruffy（不整洁的）young man in his Nike sneakers , was smart enough to break a fake story that successfully fooled the world for 35 years . “ I guess I just got lucky , ” West smiles . “ It just goes to show you don’t have to finish high school to be smart . ”
Forty Years’ Study
“ I’ve spent 40 years in as tronomical study , and 20 years of that specifically in Satellite Systems study . I have a University chair in three major Universities and sat on 5 different governmental committees on Space Exploration . Hell , I wrote
a research paper on the Lunar Landings that took 18 months to research , then a further
3 months just to correct it . ” Steven pauses to scratch his head . “ Yet not once did it occur to me to wonder who filmed Armstrong as he stepped onto the moon . How could I have been so stupid ? ”
The Evidence
● If Armstrong was the first to walk on the moon , then who filmed him walking down
the ladder ?
● There’s no gravity on the moon , so why didn’t the astronauts just float away ?
● It’s really hot on the moon , so Armstrong should have died of thirst .
● T he deadly radiation belts around the Earth turn everyone radioactive and make your eyes boil unless you are wearing 18 inches of lead（铅）. So how did they get through it ?
40. The writer thinks that Carl West __________ .
A. has fooled the world
B. wa sn’t smart when he was in high school
C. has discovered a big secret
D. is a scientist researching the moon
41. Steven mainly intended to tell us that __________ .
A. he is an expert in astronomical study
B. he is active in helping the government
C. his research paper is seriously written
D. moon landing might never have happened
42. Which of the following is NOT mentioned in THE EVIDENCE ?

C
Like my friend Warren Buffett , I feel particularly lucky to do something every day I love to do . He calls it “ tap-dancing to work ” . My job at Microsoft is as challenging as ever , but what makes me “ tap-dancing to the work ” is when we show people something new , like a computer that can recognize your handwriting or your speech , or one that can store a lifetime’s worth of photos , and they say : “ I didn’t know you can do that with a PC ! ”
But for all the cool things that a person can do with a PC , there are lots of other ways we can put our creativity and intelligence to work to improve our world . There are still far too many people in the world whose most basic needs go unmet .
I believe that I’m blessed to own good fortune . And because of that , my wife , Melinda , and I have committed to improving health and education in a way that help as many people as possible . As a father , I believe that the death of a child in Africa is no less poignant or tragic than the death of a child anywhere else . And that doesn’t take much to make an immense difference is these children’s lives .
I believe that progress on even the world’s toughest problems is possible and it’s happening every day . We’re seeing new drugs for deadly diseases , new diagnostic tools , and new attention paid to the health problems in the developing world . I’m excited by the possibilities I see for medicine , for education and , of course , for technology . And I believe that through our natural inventiveness and willingness to solve tough pro blems , we’re going to make some amazing achievements in all these areas in my lifetime .
44. When a person “ tap-dances to work ” , he __________ .
A. take delight in doing his job
B. seldom treats his work seriously

B 2. D 【解析】 【分析】 本题考查人口老龄化的影响、城市化问题的缓解措施及其影响等知识点,同时考查学生的读图分析能力。 【1题详解】 老旧小区如果即将到使用年限,应该拆除重建,再加装电梯没有意义,A错误；年轻人结婚一般是住在新楼房,老旧小区一般住的是中老年人,重庆是山城,楼房多以高层为主,上下不便,需要加装电梯,B正确；加装电梯可以提高老旧小区的附加值（房价）,我国提倡政府抑制房价,因此提高老旧小区的附加值不是政府的主要目的,C错误；电梯需求量增加,会促进制造业的发展,但是对整个行业的带动作用有限,D错误。 【2题详解】 从图中看房屋加装的电梯外部有隔离墙,而且加装的电梯与原楼房有一定间距,不会造成大的噪音干扰,A错误；房屋加装的电梯在一定程度上会影响建筑美观,但设计合理会增加美感,B 错误；房屋加装的电梯会减少公共空间,从图中看占用面积不大,因此不是主要变化,C错误；电梯安装在东西走向的楼房南部,会遮挡楼房采光,中高层的房屋原来可能采光不受遮挡,但加装电梯后采光受影响最大,D正确。 【点睛】解答本题注意材料中提到的的关键词如“老旧小区”、“重庆”、“东西向”。我国政府支持老旧小区加装电梯,有相应政策扶持及补贴；老旧小区拆迁成本较高。 美国加利福尼亚州是世界森林火灾最频繁的地区之一,每年因森林火灾损失重大。下图为森林火灾次数逐月累计图。 读图,回答下列各题。 秘密★启用前 2019年重庆一中高2019级高三上期一诊模拟考试 英语试题卷2019. 1 英语试题卷共9页。满分150分。考试时间120分钟。 注意事项： 1.答题前，务必将自己的姓名、准考证号填写在答题卡规定的位置上。 2.答选择题时，必须使用2B铅笔将答题卡上对应题目的答案标号涂黑，如需改动，用橡皮擦擦干净后，再选涂其他答案标号。 3.答非选择题时，必须使用0.5毫米黑色签字笔，将答案书写在答题卡规定的位置上。 4.所有题目必须在答题卡上作答，在试题卷上答题无效。 Ⅰ、听力理解（共两节：每小题1.5分，满分30分） 第一节(共5小题，每小题1.5分，满分7.5分) 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项，并标在试卷的相应位置。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 1．Where is Linda now?

In 2019 there will be returns to classic movie characters and stories. Here are movies not to miss. Spider-Man-.Far H0- July 5, US Tom Holland, the actor of 2017's Spider-Man: Homecoming, returns to play Peter Parker, a high school student who gains superpowers after being bitten by a spider(蜘蛛). When we see him again in theaters, Spider – Man will have a new red - and – black suit. The movie will take Peter on a global adventure outside of the US. According to Marved Studios President Kevin Feige, Spider - Man will try a return to his “normal" self; he will try to find his old powers on his new journey. Hobbs and Shaw, July 26,US To most people the Fast and Furious series is all about crazy drivers racing in sports car. But in Hobbs and Shaw, humor is added to the action - packed thrills. The new film will hit US theaters on July 26. Famous English actor Jaso n Statham will star alongside Dwayne Johnson, “The Rock”, as Deckaid Shaw and Luke Hobbs respectively, as in their previous appearances in Fast and Furious 8. The action and chemistry really thrill their audience. But the new action scenes between an MI6 agent Hobbs and the killer Shaw will have to be good to beat their stand - off in the 2017 movie.
