听力素养“漫养成”
|掌握规律技法|
(一)如何听数字
数字与计算是高考听力常考查的题型。听力中,数字常涉及年代、日期、时间、价格、电话号码、倍数、分数、约数、小数、基数词和序数词等。应特别注意的是多位数、日期、年代、房间号、电话号码以及商品“打折”的读法。另外,还要注意数字的辨音,如fourteen和forty。在实际听力训练中,要正确掌握英语数字的写法和读法,才能做出正确判断。
[典例] (2023·山东高考听力)
Q:How soon will the movie start
A.In half an hour.
B.In one hour.
C.In two hours.
[听力原文]
W:How much time do we have before the movie We won't have to hurry, will we
M:Don't worry.It's 6:30 now.We still have two hours.It takes only 30 minutes to get there.
[分析] 首先根据题干中的关键词“How soon”可知,这是一道考查时间数字的题目,听录音时要仔细听与时间相关的数字。根据男士所说的“We still have two hours”可知还有两个小时。故可得出C为正确选项。
(二)复习句子重音
 英语重音分为词重音和语句重音,两者是学习英语节奏的基础。一般来说英语句子中需要重读的词有:名词(包括专有名词)、动词、形容词、大多数副词、数词、双音节介词、特殊疑问词、指示代词等;不需要重读的词主要有:冠词、代词、be动词、单音节介词、连词、助词、关系代词和关系副词等。如:
He is a ?teacher.
他是一名教师。
?Charles was here last ?Sunday.
查尔斯上星期天在这儿。
The ?post office is ?open at ?eight.
邮局八点开门。
He ?gave Mr ?Fisher an ?old ?lock in?stead of a ?new one.
他给了费希尔先生一把旧锁,而不是新的。
He ?cooked ?two ?eggs.
他煮了两个鸡蛋。
?Take the ?first ?turning on the ?right.
在第一个路口右转弯。
?This is a ?very ?good ?ship.
这是一艘很好的船。
?What did he ?say
他说了什么?
?What ?time shall I ?come
我应当什么时间来?
?When can I ?phone you
我什么时候可以给你打电话?
?Hurry ?up!快点!
I ?always ?clean my ?teeth in the morning.
我总是在早晨刷牙。
注意:有时,为了表达特定的意义,一些通常无需重读的词也会出现重读。

Ⅰ.阅读理解
By 2035, NASA wants to land humans on Mars.But reaching the red planet, on average around 140 million miles away, will be difficult.Colder than Antarctica and with little to no oxygen, Mars is an unfriendly environment.Besides, the longer it takes astronauts to get there and the longer they stay, the more they are at risk.
That's why scientists are looking at ways to reduce trip time.Seattle-based company Ultra Safe Nuclear Technologies (USNC-Tech) has offered a solution:an NTP engine that could get humans from Earth to Mars in just three months.Such an engine takes advantage of nuclear technology.Currently, the shortest possible trip for an unmanned spacecraft is seven months, but a manned mission is expected to take at least nine months.Shorter missions would limit the astronaut's exposure to space radiation, but there is still concern about the radiation sent out from the nuclear reactor inside the spacecraft.This would be mitigated through the rocket's design.
To protect people on the ground, the NTP spacecraft would not lift off directly from Earth, Jeff Sheehy, a NASA scientist, adds.Instead, a regular chemical rocket would carry it into orbit, and only then would it fire up its nuclear reactor.Once in orbit, it could do little harm, as heat radiation cannot move through a vacuum (真空).If disaster hit and the rocket's reactor broke up, the pieces would not land on Earth — or any other planet — for thousands of years.By that time, the radioactive substance would have “naturally got to the point where it wasn't dangerous anymore”.
Michael Eades, director of engineering at USNC-Tech, says that nuclear-powered rockets would be more powerful and twice as efficient as the chemical engines used today, meaning they could travel further and faster, while burning less fuel.“Nuclear-powered rockets will be key to opening up the solar system but it could be at least two decades before they are used widely,” he says, adding that numerous demonstrations and tests would need to be carried out before an astronaut is sent to Mars in an NTP rocket.
语篇解读:本文是一篇议论文。文章讨论了NASA计划在2035年将人类送上火星的挑战,以及USNC-Tech公司提出的解决方案:利用核热推进(NTP)引擎缩短地球到火星的旅行时间。文章还讨论了这种引擎的安全性和效率,以及在实际应用之前需要进行的测试和演示。
1.What does the underlined word “mitigated” in paragraph 2 mean
A.Shortened.    B.Relieved.
C.Achieved. D.Simplified.
解析:词义猜测题。根据第二段画线词前一句可知,较短的任务会限制宇航员暴露在太空辐射中,但人们仍对航天器内核反应堆发出的辐射感到担忧;再结合“This would be mitigated through the rocket's design”可知,这种情况会通过火箭的设计得到缓解。由此可推知,“mitigated”意思是“减轻,缓和”,与“relieved”意思相近,故选B。

2.Why is the NTP spacecraft safe according to the text
A.It barely spreads radiation in orbit.
B.Its radioactive substance will disappear soon.
C.Its broken reactor will be left on Mars.
D.It doesn't give out unclear radiation in space.

解析:细节理解题。根据第三段“Once in orbit, it could do little harm, as heat radiation cannot move through a vacuum (真空)”可知,NTP航天器在轨道上几乎不传播辐射,所以是安全的,故选A。
3.What do Michael Eades' words indicate about the NTP spacecraft
A.It will fly to Mars without astronauts for tests.
B.It has been widely used for NASA.
C.It will be a breakthrough in space exploration.
D.It carries more fuel than a regular one.

解析:推理判断题,根据最后一段“Nuclear-powered rockets will be key to ...before they are used widely”可知,迈克尔·伊德斯认为核动力火箭将是开启太阳系的关键,这表明核动力火箭将是太空探索的一个突破,故选C。
Ⅱ.阅读七选五
Exploring the planets with an amateur telescope
If you're a new telescope owner, the whole sky is your playground. 4 The brightest ones stand out in the night sky and are easy to spot through your telescope.
5 In general, small telescopes with low magnification (放大率) will not show as much detail as larger amateur telescopes at higher magnification.
Many experienced amateur observers let their telescopes get used to outside temperatures. 6 While the equipment is cooling down, observers gather their star charts, warm clothes, and other accessories (配件).
Most telescopes come with eyepieces.It's always best to check the guide to see which one is best for planetary viewing.In general, look for eyepieces with names like Pl ssl or Orthoscopic, in lengths of three to nine millimeters. 7
If this all seems confusing, it's always a good idea to take the telescope to a local astronomy club, a camera store, or a planetarium (天文馆) for advice from more experienced observers. 8
It's important to research which stars will be in the sky at any given time.Magazines such as Sky & Telescope publish charts each month on their websites showing what's visible.Astronomy software packages, hike Stellarium, have much of the same information.There are also smartphone apps that provide star charts at your fingertips.
A.This takes about 30 minutes.
B.There's a wealth of information available online, too.
C.There's no “one size fits all” solution to planet-gazing.
D.But if you're a beginner, you may want to start by looking for planets.
E.The easiest object in the sky to observe with a telescope is the Moon.
F.Which one to choose depends on the size and focal length of the telescope.
G.Magnification means how many times larger a telescope will make an object look.
语篇解读:本文是一篇说明文。文章主要为刚刚买了望远镜想要观察星空的初学者提出了一些建议。
4.选D 空前一句引出话题,说明有了新望远镜就可以探索星空。空后一句提到用望远镜可以看到夜空中最亮的星星。D项“但如果你是初学者,你可能想从寻找行星开始”和上文形成转折关系,语义相衔接。下文中“The brightest ones”指代该项中的“planets”。
5.选C 下文从另一个侧面说明,在观测过程中,并不能保证所有的条件都完美,并没有可以解决一切问题的方案。C项“对于行星观测,没有‘一刀切’的解决方案”对下文进行总结,符合语境。
6.选A 结合空前和空后内容可知,该段主要讲述经验丰富的业余观察员通常会在室外调试望远镜以适应室外温度,然后再开展相关观测工作。而这中间就需要讲到冷却时间。故A项“这大约需要30分钟”承上启下,符合语境。
7.选F 空前提到要选择最适合行星观测的目镜。F项“选择哪一个取决于望远镜的大小和焦距”承接上文,符合语境。
8.选B 上文提到对于以上提到的“室外调试”“目镜选用”等建议还有困惑的情况下,可以去天文俱乐部、相机商店或天文馆等地寻求帮助。B项“网上也有丰富的信息”承接上文,符合语境。
Ⅲ.主题微写作
结合汉语提示完成下面对话。
M:I'm reading an interesting report on Mars.
W:Oh, what does it say Does it say water could ①___________ _______________________ (火星表面下仍然存在水)
M:Absolutely!It says there is water on Mars buried beneath the surface.②______________________________ (它仅仅是个有多深的问题).

To protect people on the ground, the NTP spacecraft would not lift off directly from Earth, Jeff Sheehy, a NASA scientist, adds.Instead, a regular chemical rocket would carry it into orbit, and only then would it fire up its nuclear reactor.Once in orbit, it could do little harm, as heat radiation cannot move through a vacuum (真空).If disaster hit and the rocket's reactor broke up, the pieces would not land on Earth — or any other planet — for thousands of years.By that time, the radioactive substance would have “naturally got to the point where it wasn't dangerous anymore”.
Michael Eades, director of engineering at USNC Tech, says that nuclear powered rockets would be more powerful and twice as efficient as the chemical engines used today, meaning they could travel further and faster, while burning less fuel.“Nuclear powered rockets will be key to opening up the solar system but it could be at least two decades before they are used widely,” he says, adding that numerous demonstrations and tests would need to be carried out before an astronaut is sent to Mars in an NTP rocket.

Exploring the planets with an amateur telescope
If you're a new telescope owner, the whole sky is your playground. __4__ The brightest ones stand out in the night sky and are easy to spot through your telescope.
__5__ In general, small telescopes with low magnification (放大率) will not show as much detail as larger amateur telescopes at higher magnification.
Many experienced amateur observers let their telescopes get used to outside temperatures. __6__ While the equipment is cooling down, observers gather their star charts, warm clothes, and other accessories (配件).
Most telescopes come with eyepieces.It's always best to check the guide to see which one is best for planetary viewing.In general, look for eyepieces with names like Pl ssl or Orthoscopic, in lengths of three to nine millimeters. __7__
If this all seems confusing, it's always a good idea to take the telescope to a local astronomy club, a camera store, or a planetarium (天文馆) for advice from more experienced observers.__8__
It's important to research which stars will be in the sky at any given time.Magazines such as Sky & Telescope publish charts each month on their websites showing what's visible.Astronomy software packages, hike Stellarium, have much of the same information.There are also smartphone apps that provide star charts at your fingertips.
A.This takes about 30 minutes.
B.There's a wealth of information available online, too.
C.There's no “one size fits all” solution to planet gazing.
D.But if you're a beginner, you may want to start by looking for planets.
E.The easiest object in the sky to observe with a telescope is the Moon.
F.Which one to choose depends on the size and focal length of the telescope.
G.Magnification means how many times larger a telescope will make an object look.

[语篇综合训练]
Ⅰ.阅读理解
语篇解读:本文是一篇议论文。文章讨论了NASA计划在2035年将人类送上火星的挑战,以及USNC Tech公司提出的解决方案:利用核热推进(NTP)引擎缩短地球到火星的旅行时间。文章还讨论了这种引擎的安全性和效率,以及在实际应用之前需要进行的测试和演示。
1.选B 词义猜测题。根据第二段画线词前一句可知,较短的任务会限制宇航员暴露在太空辐射中,但人们仍对航天器内核反应堆发出的辐射感到担忧;再结合“This would be mitigated through the rocket's design”可知,这种情况会通过火箭的设计得到缓解。由此可推知,“mitigated”意思是“减轻,缓和”,与“relieved”意思相近,故选B。
2.选A 细节理解题。根据第三段“Once in orbit, it could do little harm, as heat radiation cannot move through a vacuum (真空)”可知,NTP航天器在轨道上几乎不传播辐射,所以是安全的,故选A。
3.选C 推理判断题,根据最后一段“Nuclear powered rockets will be key to ...before they are used widely”可知,迈克尔·伊德斯认为核动力火箭将是开启太阳系的关键,这表明核动力火箭将是太空探索的一个突破,故选C。
Ⅱ.阅读七选五
语篇解读:本文是一篇说明文。文章主要为刚刚买了望远镜想要观察星空的初学者提出了一些建议。
4.选D 空前一句引出话题,说明有了新望远镜就可以探索星空。空后一句提到用望远镜可以看到夜空中最亮的星星。D项“但如果你是初学者,你可能想从寻找行星开始”和上文形成转折关系,语义相衔接。下文中“The brightest ones”指代该项中的“planets”。
5.选C 下文从另一个侧面说明,在观测过程中,并不能保证所有的条件都完美,并没有可以解决一切问题的方案。C项“对于行星观测,没有‘一刀切’的解决方案”对下文进行总结,符合语境。
6.选A 结合空前和空后内容可知,该段主要讲述经验丰富的业余观察员通常会在室外调试望远镜以适应室外温度,然后再开展相关观测工作。而这中间就需要讲到冷却时间。故A项“这大约需要30分钟”承上启下,符合语境。
7.选F 空前提到要选择最适合行星观测的目镜。F项“选择哪一个取决于望远镜的大小和焦距”承接上文,符合语境。
8.选B 上文提到对于以上提到的“室外调试”“目镜选用”等建议还有困惑的情况下,可以去天文俱乐部、相机商店或天文馆等地寻求帮助。B项“网上也有丰富的信息”承接上文,符合语境。
