7．There was an oil painting ________ in the corner.It ________ there for several days.

C．lying；had lain D．laid；had been lain
解析此题考查动词lie/lay的具体运用。

第一个空应该作定语修饰painting。

可用两种形式：一是lying，是lie的现在分词，表示状态；二是laid，是lay表示“放置”的过去分词，与painting是被动关系。

但第二个空只能是had lain。

lain是lie表示“躺”的过去分词，没有被动形式。

A．make B．to make
C．from making D．making
解析句意：人们对于消防队员为了使环境更加安全而防止火灾所付出的努力将会感激的。

prevent后面也可接宾语，表示“防止某事的发生”，挖空的地方是全句的目的状语，所以要用不定式。

A．as a result B．after all
C．any way D．otherwise
解析句意：我的朋友马丁得了一种发烧的怪病，结果，他既不能吃饭也不能睡觉。

that she is trustworthy.
A．depend on B．attend to

解析句意：我宁愿直到我非常相信玛丽的诚实为止我才指望她。

A．puzzled，be puzzled by，puzzling
B．puzzling，was puzzled by，puzzled
C．puzzled，was puzzling over，puzzling
D．puzzling，be puzzled over，puzzled
解析puzzled多叙述人的感受。

puzzled look感到困惑的表情。

第二个空填入was puzzling over表示“苦思”，与主语she是主谓关系；第三个空填入puzzling修饰maths，表示“让人感到困惑的数学题”。

答案 C
13．—It remains to be seen ________the plan can be put into practice.
—It depends on your determination.
A．that B．how
C．where D．whether
解析句意：这项计划能否付诸于实践中还尚待分晓。

A．exists B．exist
C．existed D．had existed
解析句意：乔娜是一个很自傲的人，她总是走路就好像别人不存在似的。

这是一个虚拟语气，as if从句中的动词exist与主句动作walking在时间上是同时的，所以从句要用一般过去时。

答案 C
15．Blamed for breaking my promise，I felt my face ________ hot，and hung my head in shame.
A．to grow B．to be growing
C．grow D．grown
解析句意：我由于违背诺言而受到责怪，所以我觉得脸越来越发烫，不好意思地垂下了头。

grow是不带to的不定式，与宾语face 是主动关系。

答案 C
Ⅱ.阅读理解
A
The next time you take a bath，watch what happens when you pull the plug from the drain(排水管)in the bathtub(浴缸)．You will see the water turn around quickly down the drain.The water will move fast enough to create a whirlpool(漩涡)．That is similar to how black holes work.
How Do Black Holes Work?
Black holes use the power of gravity.For example，the pull of Earth’s gravity keeps us on the ground.We would float off into space if there were no gravity.
Now imagine this.The pull of a black hole is many times more powerful than the pull of sun.It is so powerful that even light cannot escape its pull.That is why it is called a black hole.
______________________________________________________ __________________
Black holes are formed when giant stars die.Young stars burn gases that give off heat.Finally stars get old and run
out of gas and heat.When this happens，they shrink.As they get smaller and smaller，the pull of their gravity grows stronger and stronger.In time they get so small that they cannot be seen.
How Do We Know Black Holes Are there?
Scientists first predicted the existence of black holes more than 200 years ago.However，they did not have any way to prove their idea.In 1990 the United States sent a special craft to move around Earth.They couldn’t see a black hole directly，however，they could see circling gases in outer space.The circling gases looked like the whirlpool that water makes when it rushes down a bathtub drain.These whirlpools proved that black holes really exist.
1．The underlined word “shrink” in the fourth paragraph probably means “________”．
A．disappear suddenly B．stay young
C．become smaller D．become hotter
2．Black holes got their name because ________.
A．they cause young stars to die
B．they keep light from escaping
C．they keep people from entering space
D．they pull water down a drain
3．The author begins this passage with a paragraph about
bathtub to ________.
A．give a simple example of how black holes work
B．tell us how the sun’s gravity keeps the planets in place C．warn us about the danger while bathing
D．show what happens when a star gets old and loses its energy
4．Which of the following can fill in the blank in the passage?
A．What Are Black Holes?
B．The Danger Of Black Holes
C．How Do Black Holes Form?
D．How Stars become Smaller and Smaller
5．According to the passage，what made scientists believe black holes do exist?
A．The changing color of the sun.
B．A few giant stars that were near one another.
C．The whirlpools in the bathtub.
D．Gases that were circling around like a whirlpool.
1．C 词义猜测题。

由下句可知，shrink的意思是“收缩；缩小”。

2．B 细节理解题。

根据“It is so powerful that even light
cannot escape its pull.”可知。

3．A 文章结构题。

短文首先用浴缸水流入下水道的例子打比方，是为了让我们更好地了解什么是黑洞。

4．C 主旨归纳题。

根据本段的文字信息可知，作者旨在介绍了黑洞是如何形成的。

5．D 主观推断题。

根据最后一段，科学家证实黑洞存在的事实是因为“在它周围有像旋涡一样的气体。
