不积跬步无以至千里，不积小流无以成江海。 课时分层作业(六)
Ⅰ.阅读理解
A
Orville Wright was born on August 19，1871 in Dayton，Ohio，USA and died on
January 30，1948.Together with his brother，Wilbur (April 16，1867—May 30，1912)，he was the first airplane builder.The brothers created the first controlled，powered and
heavierthanair human flight.
Their parents were Milton Wright and Susan Catherine Koerner and besides the
two famous brothers they had five children.One day after a trip their father brought a
small helicopter as a gift.The kids loved it and as they played daily with it，it broke after
a while.The brothers managed to create a new one.Wilbur even let go his plans of
attending Yale.He spent his time helping his sick mother and reading in his father's
library.
In 1884 the family decided to move to Dayton and they remained there until the
1870's.A printing press was built by the two and Wilbur was an editor.In 1892 they
started being fascinated by the aeronautical(航空的) events of that time.Then they
started to create an airplane and Wilbur was considered the head of the team.They were
the inventors of“three-axis control”，which permitted the pilot to steer the aircraft's
balance.
In 1900 they had their first attempt to make a functional glider(滑翔机)—of course
it didn't have a pilot.After three years they thought of introducing an engine to the
glider.At first，their patent application was refused in 1903，but after one year it was
accepted.
Orville's first flight lasted 12 seconds and had 36.5 metres.He was responsible
with the public shows near Washington in the United States.On September 9，1908 his
flight was 62 minutes and 15 seconds long and the success was huge.
【语篇解读】 本文主要介绍了飞机发明家莱特兄弟——奥维尔·莱特和维尔伯·莱特，包括他们的爱好、发明以及对人类进步做出的巨大贡献。
1．What might make Wright brothers interested in the plane?
A．The pleasant trip. 不积跬步无以至千里，不积小流无以成江海。 B．Catherine's education.
C．The political events.
D．Their father's gift.
D [细节理解题。根据第二段中的“One day after a trip his father brought a
small helicopter as a gift.The kids loved it and as they played daily with it，it broke after
a while.The brothers managed to create a new one.”可知，是父亲带回来的飞机模型使莱特兄弟对飞机产生了兴趣。故选D。]
2．Wilbur didn't go to Yale probably because________．
A．he had to create a plane
B．he didn't have enough money
C．he would like to learn by himself
D．his mother asked him to stay at home
A [推理判断题。根据第二段中的“The brothers managed to create a new
one.Wilbur even let go his plans of attending Yale.He spent his time helping his sick
mother and reading in his father's library.”可知，维尔伯因为制造飞机而没有去耶鲁大学上学。故选A。]
3．The underlined word“steer”(in Paragraph 3)probably means“________”．
A．keep B．drive
C．learn D．enjoy
A [词义猜测题。由画线词所在句“They were the inventors of‘three-axis
control’，which permitted the pilot to steer the aircraft's balance.”可知，“threeaxis
control”肯定是有助于保持飞机平衡的东西，故画线词的含义是“保持，维持”。故选A。]
4．This passage tells us about________．
A．the plane's history
B．Milton and his children
C．Wright brothers' lives
D．the development of science
C [主旨大意题。本文主要讲述了莱特兄弟的生平。故选C。]
B 不积跬步无以至千里，不积小流无以成江海。 Sure，you talk to your parents，but what if you need to really talk? Maybe you have
a problem you can't solve alone，or it could be that you want to feel closer to Mom and
Dad.
It's easy to say“Hi，Mom”or“Dad，can you pass the potatoes？”，but it can
be harder to start a discussion about tougher topics.When you were younger，it probably
felt easy to tell your parents about your trouble.Even though you're older now，it's still
perfectly OK to believe in your parents.In fact，it can help a lot.
So why does it seem so uncomfortable at times? Why is it hard to bring up the
important stuff? Sometimes kids don't speak up because they don't want to feel
embarrassed(尴尬的).Let's face it—talking about personal stuff can make you feel
embarrassed.But remember，your parents know you pretty well，and they were your age
once，too! So don't let a little embarrassment stop you.It's OK to go ahead and share
the personal stuff.
Other times，kids might not want to make their parents anxious or upset.As you
explain your problem，your mom might look sad or your dad might look worried.But
that's OK.Your mom and dad can deal with knowing about your problem，big or
small.That look on their face just means they care，and they feel for you.That's what
families do—we feel for the people we love.
Sometimes，kids don't bring up a problem because they just don't want to think
about it.They hope it will just go away.When meeting a problem，they will likely choose
not to face it or just keep it for themselves.But running away from a problem hardly
ever solves it.And bottling up your feelings can make you feel stressed.

2019年12月7日16时52分，我国在太原卫星发射中心用快舟一号甲运载火箭，采用“一箭六星”的方式，成功将和德二号A/B卫星、天仪16/17卫星、天启四号A/B卫星发射升空。这是太原卫星发射中心在6个小时之内的第二次发射,创下了中国航天发射的新纪录.据此回答下题。

A．7日8时52分 B．7日0时52分
C．8日8时52分 D．8日0时52分
A ［国际标准时间是中时区的区时，即伦敦时间。北京时间是东八区的区时，伦敦在北京西边，区时计算按“东加西减"的办法，两地时区相差8个小时,所以国际标准时间比北京时间晚8小时,时间是7日8时52分。］
2．关于东十二区和西十二区的说法，错误的是（ )
A．钟点完全相同
B．相差1小时
C．相差24小时
D．180°是其共同的中央经线
