9．"I don't understand what you are saying，"she said，with a __________ expression on her face．（　�。�
A．puzzlingB．puzzledC．puzzleD．puzzlement

分析 "我不理解你說的．"她說，臉上帶著困惑的表情．

解答 答案是B．本題考查分詞的用法．題干中主要考查puzzled 和puzzling的區(qū)別：說明"（人）感到困惑的狀態(tài)"用過去分詞，說明"（物） 令人困惑的特性"用現(xiàn)在分詞；本題是說明她"感到困惑的表情"，所以答案選擇B．

點評 在非謂語動詞的解題中要在掌握其基本用法的基礎(chǔ)上關(guān)注并積累一些固定用法，結(jié)合具體語境做出合理的判斷．

19．What should you think about when you try to find your career？You are probably better at some school subjects than others．These may show strengths that you can in your work．A boy who is good at mathematics can use that in engineering career．A girl who spells well and likes English may be good at office work．So it is important to know the subjects you do well in at schools．On the other hand，you may not have any specially strong or weak subjects but your records show a general satisfactory standard．Although not all subjects can be used directly in a job，they may have indirect value．
Your school may have taught you skills，such as typing or technical drawing，which you can use in your work．You may be good at mental work or cookery and look for a job where you can improve these skills．

Facing your weak points is also part of knowing yourself．You may be all thumbs （笨手笨腳）when you handle tools； Perhaps you are a poor speller or cannot add up a column of figures．It is harder to face any weaknesses than to pretend they do not exist．Your school record，for instance，may not be too good，yet it is an important part of your background．You should not feel sorry about it but，instead，recognize that you will have a chance of a fresh start at work．
62．The first paragraph of the passage mainly talks about．B

A．knowing about one's strong and weak points
B．developing one's abilities useful in school work
C．gaining useful knowledge by working hard at school
D．choosing a career according to what one is skilled in．

20．Car crashes are the top killer of American teenagers．Most of the crashes result from distracted driving-not paying attention to the road．
Ryan Didone was a fifteen-year-old passenger in a car that hit a tree．He was one of the nation's more than thirty thousand victims of traffic crashes in 2008．Nearly four thousand deaths，about twelve percent involved drivers age fifteen to twenty．
Ryan's father，Thomas Didone，is a police captain in Maryland．"It was an inexperienced，immature driver driving at night with a carload of kids．He was distracted，he was going too fast，and it ended up causing one death and some seriously injured．"He shares the story of his son's death to help educate teens and their families about distracted driving．
Jim Jennings from the Allstate Insurance Company says the number one cause of distracted-driving accidents is the mobile phone．He says talking on the phone or reaching for it is like drinking four beers and driving．"If you're texting while driving，you are twenty-three times more likely to get into an accident than somebody who isn't．"
Government and private groups are using public service announcements and events to bring more attention to the problem．For example，the insurance industry recently held a safety event for teen drivers．At first，nineteen-year-old Kevin Schumann easily avoided large，inflatable dolls thrown in front of the car to represent children．He also avoided orange cones representing the edge of the road．Then，as part of the test，he started texting．He hit several cones and at least one doll．"That's what really opened up the experience for me to prove how bad it is to really text and drive．"
Debbie Pickford of Allstate Insurance says teens are especially at risk from distracted driving-and not just because they lack experience on the roads．"According to the research，teens don't really have fully developed brains until they're twenty-five years old．You put those two things together and you get a much，much higher risk．"
A new law proposes a graduated driver licensing system．Graduated means teenagers start with restrictions like on night driving and numbers of passengers．They could not get a full driver's license until age eighteen．
45．Of all the following，which is the best title for the passage？C
A．Car Crashes-the Top Killer       B．Drunken Driving
C．Distracted Driving               D．How to Avoid Car Crashes
46．According to Jim Jennings，what might be the main cause of distracted driving accidents？
A．Speed．B．Age．C．Experience．D．Cell-phones．
47．Which of the following statements is true？C
A．Thomas Didone is responsible for his son Ryan's death．
B．The insurance companies benefit a lot from teen driving．
C．Kevin Schumann took the test to learn the risk of texting while driving．
D．Debbie Pickford thinks that people cannot drive until brains are fully developed．
48．According to the new law，A．
A．it will be harder for young people to get a full driver's license
B．people will not be allowed to touch the wheel until they are 18
C．young people are forbidden to take any passengers in their cars
D．people can't drive until they graduate from colleges or universities．
