--Yes,and he admitted ____ his boss on a rainy night seven years ago.(  )
A.to killB.to have killed

分析 --警察已经抓住了凶手.
--是的,并且他承认七年前的一个雨夜杀了他的上司.

解答 答案是C.本题考查动名词;题干中admit 后接动名词,所以排除A和B;kill的动作发生在谓语动词admitted之前,故需要动名词的完成式,答案选C.

点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.要关注常见非谓语动词的搭配.

12.I arrived at my mother's home for our Monday family dinner.The smells of food flew over from the kitchen.Mother was pulling out quilt(被子)after quilt from the boxes,proudly showing me their beauties.She was preparing for a quilt show at the Elmhurst Church.When we began to fold and put them back into the boxes,I noticed something at the bot tom of one box.I pulled it out."What is this?"I asked.
"Oh?"Mom said,"That's Mama's quilt."
I spread the quilt.It looked at i f a group of school children had pieced it together; irregular designs,childish pictures,a crookedline on the right.
"Grandmother made this?"I said,surprised.My grandmother was a master at making quilts.This certainly didn't look like any of the quilts she had made.
"Yes,right before she died.I brought it home with me last year and made some changes,"she said."I'm still working on it.See,this is what I've done so far."

"Oh,this is so nice,Mom,"I said.It occurred to me that by completing my grandmother's quilt,my mother was honoring her own mother.I realized,too,that I held in my hands a family treasure.It started with the loving hands of one woman,and continued with the loving hands of another.

19.Some kids love going off to camp in the summer,playing volleyball,swimming,and so on.But I know that some kids absolutely hate it because I was one myself.They hate the cold sea and getting sand in their clothes and they hate being picked last for the volleyball team.(36)D It's especially for those kids who would rather spend time playing computer games than running around getting dirty.But you won't be playing computer games,this course allows you to design them.
(37)GTwo top game designers Mike Jones and Mel Wilson from the company Star Games are responsible for making favorites such as Mickey the Monkey and Rainforest Expedition.They will teach you the steps that go into creating a new game,and teach you how to use various computer programs and build some simple games yourself.
(38)BYou won't have to sleep in a tent either.Kids on the course will stay at a local hotel,where there is a gym,computers and a great canteen.No cooking on a campfire in the cold!
(39)FLast year,the course was extremely popular but it was only five days.This year we're having an additional three days.So that's over a week of gaming!
To go on the course,you need to be between thirteen and seventeen years old.(40)E We only have space for twenty-two people.That's slightly fewer than last year's twenty five,because we don't have as many teachers on the course this year.So hurry up and book your place!
If you're still not sure whether to join or not,have a look at the website www.teengames.net,that's www.teengames.net and you can see what the students did on the course last year.You can book your place on the same site.

A.One is never too old to learn.
B.Don't worry about the living place.
C.You will receive comfortable service.
D.That's why our course is so appealing.
E.Places on the course are limited,though.
F.The length of the course will be increased.
G.You will get the chance to learn from experts.
9.Every day,hundreds of thousands of us visit coffee shops.While we drink our coffee,we may connect our smartphone to the shop's Wi-Fi network,and keep in touch with friends via services such as Facebook.
As well as socializing,we may use the time and free access to a wireless connection to get on top of our finances.Transferring money from your account to others'accounts is nothing more than a few taps on your screen.
But what coffee drinkers do not realize is that lurking(潜伏) among their fellow coffee-lovers are bank robbers.
Unbeknown to you,this modern form of bank robber is silently collecting all your private data.The only sign of his thievery is perhaps a little smile as your bank log-in details appear on his screen.
You'll only realize when you later go to a cash machine to withdraw(提取)some money,and discover that every penny in your account has been cleared out.
The common method for thieves is to use your smartphone's Wi-Fi connection.They rely on the fact that most of us are not careful about the security of networks we connect to.
For example,when you are in a coffee shop,your smartphone will present you with a list of available Wi-Fi networks that you can use to connect your phone to the Internet.Most of these networks are run by legitimate(合法的)companies,but sometimes they are actually created by a thief sitting nearby with little more than a laptop.
These networks are often given names,such as"Free Public Wi-Fi",which deceive smartphone users into logging in.On the surface,everything seems normal,and you will be able to connect just as you are with a legitimate Wi-Fi service.
However,because you have connected to a network controlled by a thief,he can monitor everything you do,enabling him to collect passwords and log-in details about your bank account.
21.The underlined phrase"get on top of"can be replaced byA.
A.handleB.give upC.cut offD.set up
22.What can we learn from the passage?C
A.Transferring money from your account to others'is a complex process.
B.It's easy for you to tell bank robbers from other coffee drinkers.
C.Online thieves could steal money because people pay little attention to the security of networks.
D.All the available networks in a coffee shop are illegal.
23.What's the author's attitude towards Wi-Fi traps?C
A.Positive.B.Negative.C.Objective.D.Indifferent.
24.What's the best title of this passage?A
A.Be cautious about free Wi-Fi networks.B.The thief who withdraws our money.
C.The convenience of free Wi-Fi networks.D.The process of stealing money.
16.How many things can you see in the night sky?A lot!On a clear night you might see the Moon,some planets,and thousands of sparkling stars.
You can see even more with a telescope.You might see stars where before you only saw dark space.You might see that many stars look larger than others.You might see that some stars that look white are really red or blue.With bigger and bigger telescopes you can see more and more objects in the sky.And you can see those objects in more and more detail.
But scientists believe there are some things in the sky that we will never see.We won't see them with the biggest telescope in the world,on the clearest night of the year.
That's because they're invisible.They're the mysterious dead stars called black holes.
You might find it hard to imagine that stars die.After all,our Sun is a star.Year after year we see it up in the sky,burning brightly,giving us heat and light.The Sun certainly doesn't seem to be getting old or weak.But stars do burn out and die after billions of years.
As a star's gases burn,they give off light and heat.But when the gas runs out,the star stops burning and begins to die.
As the star cools,the outer layers of the star pull in toward the center.The star squashes into a smaller and smaller ball.If the star was very small,the star ends up as a cold,dark ball called a black dwarf.If the star was very big,it keeps squashing inward until it's packed together tighter than anything in the universe.
Imagine if the Earth were crushed until it was the size of a tiny marble.That's how tightly this dead star,a black hole,is packed.What pulls the star in toward its center with such power?It's the same force that pulls you down when you jump-the force called gravity.A black hole is so tightly packed that its gravity sucks in everything-even light.The light from a black hole can never come back to your eyes.That's why you see nothing but blackness.
So the next time you stare up at the night sky,remember:there's more in the sky than meets the eye!Scattered in the silent darkness are black holes-the great mystery of space.

A.It is usually bigger than a white dwarf.
B.It is dark.
C.It is smaller in size than a common star.
D.It is cold.
77.Why can't you see light when you look at a black hole?D
A.For most black holes are so far away.
B.As the star's gases burn,it stops giving off heat and light.
C.As a star cools,its outer layers pull in toward its center.
D.The gravity of a black hole is so strong that it sucks the light inward.
13.Everyone talks about the"five"senses of man.And it is true that we get our information (信息) about the outside from our sense of sight,hearing,smell,touch and taste.Researchers tell us that the sense of sight-our visual sense-gives us up to 80% of what we know about the world outside our bodies; while the other senses,the auditory (hearing),the olfactory (smell),the tactile (touch),and the gustatory (taste) bring into our brains information about the other 20% of what is happening.But there are two other senses that we cannot get along without,though they are little noticed.These are the senses of balance (平衡),without which we would act like a drunk after a heavy drink,and the kinesthetic sense(动觉),which gives us our ideas about our own motion (运动).
