13.He made another wonderful discovery,_____ of great importance to science.(  )
A.which I think isB.which I think it is
C.which I think itD.I think which is

分析 他又做了一个奇妙的发现,我认为这对科学很重要.

解答 A考查定语从句.本句是一个非限制性定语从句,先行词是discovery,在定语从句中做主语,I think在定语从句中是插入语,所以用关系代词which引导,故答案选A.

点评 定语从句又称为形容词性从句,综观历年高考试题,我们可以发现该语法项目是测试中的热点与难点,解定语从句的题目首先要知道哪一句是主句,哪一句是从句,被修饰的词是谁,从句中的句子成分缺失什么,根据缺失成分的不同从而选出相对应的关系代词或者关系副词,从而选出正确的答案,解题的关键是从句句子的成分分析.

4.Ed Viesturs grew up in Rockford,Illinois,where the tallest thing on the horizon was the water tower.But on Thursday,Viesturs became the only American to climb to the top of the world's 14highest mountains.
His last hike was up Mount Annapurna,in Asia's snowcapped Himalayas.At 26,545feet,its peak is the 10th highest in the world.It is the mountain that inspired him to start climbing.
"It tends to be the trickiest,the most dangerous,"said Viesturs."There's no simple way to climb it.There are threatening avalanches and ice falls that protect the mountain.
In high school,Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna.Herzog's story was of frostbite and difficulty and near-death experiences.Viesturs was hooked right away.
Viesturs got his start on Washington's Mount Rainier in 1977,guiding hikes in the summer.Fifteen years ago,he set out to walk up to the world's highest peaks.Finally,he's done.
The pioneering climber talks about mountains as if they were living creatures that should be treated with respect."You have to use all of your senses,all of your abilities to see if the mountain will let you climb it,"said Viesturs."If we have the patience and the respect,and if we're here at the right time,under the right circumstances,they allow us to go up,and allow us to come down."
What's next for a man who can't stop climbing?"I'm going to hug my wife and kids and kind of kick back and enjoy the summer,"says Viesturs.But for a man who's climbed the world's 14tallest mountains,he will probably soon set off on yet another adventure.

59.What record has Ed Viesturs set?B
A.He has succeeded in climbing to the world's 14th highest mountain.
B.He has been to the top of the world's 14highest mountains.
C.He has become the first to climb to the height of 26,545feet.
D.He has become the first man to climb to the top of 14highest mountains in the world.
60.The underlined word"hooked"in Paragraph 4can be replaced by"C".
A.frightened B.discouraged C.interested  D.upset
61.The author used Viestures'words in the last paragraph to support a view thatB.
A.mountain climbing is a dangerous sport
B.mountains should be regarded as living creatures
C.mountain climbing needs more skills than physical energy
D.those who like mountain climbing won't stop climbing.

18.I almoWith rates as low as $3.75per week!
"Well,I finally did it.I finally decided to enter the digital age and get a cell phone.My kids have been annoying me and the last straw was when my car broke down,and I was stuck by the highway for an hour before someone stopped to help.But when I went to the cell phone store,st changed my mind.The phones all have cameras,computers and a"global-positioning"something or other that's supposed to spot me from space.Goodness,all I want to do is to be able to talk to my grandkids!The people at the store weren't much help.They couldn't understand why someone wouldn't want a phone the size of a postage stamp.And the rate plans!They were confusing,and expensive…and the contract (合同)lasted for two years!I'd almost given up until a friend told me about her new Jitterbug phone.Now,I have the convenience and safety of being about to stay in touch---with a phone I can actually use."
Affordable plans that I can understand一and no contract to sign (签订)!Unlike other cell phones,Jitterbug has plans that make sense.Why should I pay for minutes I'm never going to use?And if I do talk more than I plan,I won't find myself with no minutes like my friend who has a prepaid phone.Best of all,there is no contract to sign-so I'm not locked in for years at a time.The US-based customer service is second to none.And the phone gets service anywhere in the country.

2.There are some strong-minded people that are able to stop smoking today and be free from the addiction the next day.However,some smokers may have to seek help from medication (药物治疗) in order to kick the habit.
What medication actually does is to reduce the wish to smoke.Some of the medication must be taken with a doctor's guidance.The five most common medications to stop smoking are Bupropion SR,nicotine gum,nicotine inhalers(吸入器),nicotine nasal spray(鼻腔喷剂) and nicotine patches.People can buy nicotine gum and nicotine patches in chemists.However,the other medications require a prescription.
Zyban tablets(药片)have been found to be highly effective in curing people of smoking addiction.The tablet needs to be taken whole,without crushing (碾碎)it,as crushing can lead to side effects.It can be bought on the prescription of a doctor.
Nicotine patches are filled with nicotine and they are applied to the skin.The skin takes in the nicotine and carries it to the blood stream.The amount of nicotine in these patches is quite limited,not enough to lead to addiction.But you shouldn't take them for dinner.In fact,millions of people have benefited from these nicotine patches.
Nicotine gum is supposed to be a safer choice.It is used in such a way that it comes into contact with the blood vessels (脉管) in the mouth and then releases the nicotine.The nicotine should not go through the stomach; otherwise,it may cause certain side effects.
These different types of medications have to be taken quite carefully.Do ask your doctor before taking any of these.
