选择性必修第二册 UNIT 1 SCIENCE AND SCIENTISTS
Ⅰ.阅读理解
Jose Hernandez made his dream of becoming an astronaut a reality and he did so
despite unbelievable difficulties.
“I was working in a field near Stockton，and I heard on my radio that Franklin
Chang-Diaz had been selected for the Astronaut Corps，”said Jose，who was a
senior in high school at the time.“I was already interested in science and
engineering，”Jose remembered.“But that was the moment I said，‘I want to fly
in space.’”
As one of four children in a migrant(移民)farming family from Mexico，Jose—who
didn’t learn English until he was 12 years old—spent much of his childhood traveling
with his family from Mexico to southern California each March ，then working
northward to the Stockton area by November，picking strawberries and cucumbers at
farms along the route.They would then return to Mexico for Christmas and start the
cycle all over again in the spring.“Some kids might think it would be fun to travel
like that，”Jose laughed.“But we had to work.”
After graduating from high school，Jose was admitted into the University of the
Pacific.In 1987，he accepted a full-time job with Lawrence National Laboratory.In
2001，Jose joined the Johnson Space Centre，where he came face-to-face with
Franklin Chang-Diaz.
“We actually had common experiences—a similar upbringing，the same language
issues.That built up my confidence.Any barriers that existed ， he had already
overcome them，”Jose smiled.“Now it’s my turn！”
“NASA rejected me not once，not twice，not three times but 11 times.It wasn’t
until the 12th time that I got selected，”he said.Jose was selected as part of the 19th
class of astronauts in 2004.He circled the globe 217 times but remains a down to
Earth guy.Jose Hernandez received the 2016 National Hispanic Hero Award and he continues
his long history in the field of engineering and space.

People who regularly sleep for six hours or less each night in middle age are more
likely to develop dementia (痴呆) than those who routinely manage seven hours，
according to a major study into the disease.
Researchers found a 30% greater risk of dementia in those who during their 50s，60s
and 70s consistently had a short night’s sleep，regardless of other risk factors such as
heart condition and poor mental health.
Sabia，an author of the study at the University of Paris and her colleagues analyzed
survey data from University College London’s Whitehall study，which launched in
1985 and followed the health and lifestyles of more than 10 ， 000 British
volunteers.The French team focused on nearly 8，000 participants who self-reportedtheir sleep patterns.
During 25 years of follow-up，521 participants developed dementia，with most
diagnosed in their late 70s.Writing in Nature Communications ， the scientists
described how those who routinely got six hours of sleep or less each night in their
50s and 60s were 30% more likely to develop dementia than those who typically
managed seven hours.
The study does not prove that sleeping too little causes dementia，since sleep loss
itself may be one of the earliest symptoms of the disease.But some scientists believe
the results strengthen evidence that continuous poor sleep may at least contribute to
the disease.
The first pathological changes that lead to dementia occur one to two decades before
the disease becomes obvious，as sticky proteins called amyloid build up in the
brain.When the 1985 Whitehall study first assessed the sleep of volunteers who later
developed dementia，this process had probably not started.This meant that if they
were sleeping too little，it was unlikely to have been caused by dementia-related
brain changes.
“It strengthens the evidence that poor sleep in middle age could cause or worsen
dementia in later life，” said Dr.Liz Coulthard，a consultant senior lecturer in
dementia neurology.“It makes sense to take measures to improve sleep such as going
outside during daylight hours to help maintain the natural rhythms that promote good
sleep，avoiding too much alcohol or caffeine，particularly before bed，and finding
a bedtime routine that works for you.”
5.What risk factor for dementia does the passage focus on?
A.Sleep loss. B.Age.
C.Poor mental health. D.Heart condition.
6.How did French scientists get the research findings?
A.By making a comparison.
B.By monitoring sleep patterns.
C.By interviewing British volunteers.
D.By analyzing previous survey data.7.In what tone do the scientists talk about the research?
A.Casual. B.Doubtful.
C.Negative. D.Cautious.
8.What is the purpose of the last paragraph?
A.To give examples.
B.To collect proofs.
C.To offer suggestions.
D.To present arguments.

Ⅲ.【语篇解读】 本文是说明文。文章介绍了一项新的研究。研究表明，影响
体重变化的最大因素是饮食的量和频率，而不是从第一顿饮食到最后一顿饮食
的间隔时间，该研究发现挑战了间歇性禁食作为一种有用的减肥策略的流行趋势。
1.finding [考查非谓语动词。分析句子可知，句子成分完整，空处用非谓语动
词形式，find是句中have followed the meal-time habits...自然发生的结果，应用
find的现在分词形式finding，作结果状语。故填finding。]
2.frequency [考查词性转换。分析句子可知，空处和size并列，作介词by的宾
语，应用frequent的名词形式frequency，表示“(发生的)频率”，是不可数名词。
故填frequency。]
3.as [考查介词。结合常识可知，间歇性禁食常被当作一种有用的减肥策略，
空处应用介词as，表示“当作”。故填as。]
4.are consumed [考查时态语态和主谓一致。句意：间歇性禁食，也被称为限时
进食，是一种饮食策略，每天在短时间内食用所有食物。句子在解释间歇性禁
食的内涵，是一般性的事实，应用一般现在时，where引导的同位语从句与主
句时态保持一致，空处作从句的谓语，和主语 all meals之间是被动关系，应用
一般现在时的被动语态，且主语是复数，be动词用are。故填are consumed。]
5.there [考查there be句型。分析句子可知，reveals后面接了省略了that的宾语
从句，从句中表示两者之间没有关联，应用 there be句型，空处填there。故填there。]
6.ours [考查代词。分析句子可知，空处作介词including的宾语，表示“我们
的研究”，应用名词性物主代词。故填ours。]
7.an [考查冠词。空处表示泛指，意为“一个，一种”，应用不定冠词，且
instant的发音以元音音素开头，应用an。故填an。]
8.what [考查名词性从句。suggests后接了省略了that的宾语从句，从句中缺少
表语，空处需引导名词性从句作 is的表语，表语从句中缺少主语，指物，应用
连接代词what。故填what。]
9.seen [考查非谓语动词。that 引导的表语从句中主要成分完整，空处作
benefits的后置定语，且see和benefits之间为逻辑上的动宾关系，应用see的过
去分词形式seen。故填seen。]
10.to lose [考查非谓语动词。此处用了固定短语expect to do sth，表示“期待
做……”，空处需用不定式的形式to lose作expect的宾语。故填to lose。]
