1．Three-fourths of the buildings _________．（　　）
A．were destroyedB．is destroyed
C．was destroyedD．has been destroyed

分析 大樓的四分之三被摧毀了．

解答 A 考查主謂一致．句意：大樓的四分之三被摧毀了．分數(shù)做主語，謂語動詞的選擇要根據(jù)of后面名詞的可數(shù)與不可數(shù)來確定，buildings是可數(shù)名詞，故它的四分之三還是可數(shù)名詞，謂語動詞用復數(shù)形式，故選A．

點評 主謂一致是高考的重要考點之一，解決此類題目要找準句子主語，判斷句子主語究竟是單數(shù)還是復數(shù)． 在英語句子里，謂語受主語支配，其動詞必須和主語在人稱和數(shù)上保持一致，這就叫主謂一致．尋其規(guī)律，大致可歸納為三個原則，即語法一致、邏輯意義一致和就近一致原則．

18．China is a land of bicycles．At least it was back in 1992when I traveled the country．Back then everyone seemed to be riding a bicycle．Millions of them，all black．Cars were rare．Yet since my arrival in Beijing last year，I  found the opposite is true．There are millions of cars．However，people still use their bicycles to get around．For many，it's the easiest and cheapest way to travel today．Bicycles also come in different colors--silver，green，red，blue，yellow，whatever you want．
It's fun watching people biking．They rush quickly through crossroads，move skillfully through traffic，and ride even on sidewalks（人行道）．Bicycles allow people the freedom to move about that cars just can't provide．
Eager to be part of this aspect of Chinese culture，I decided to buy a bicycle．Great weather accompanied my great buy．I immediately jumped up on my bicycle seat and started home．
My first ride home was orderly （守秩序的）．To be safe，I stayed with a"pack"of bikers while cars on the streets came running swiftly out of nowhere at times．I didn't want to get hit．So I took the ride carefully．
Crossing the streets was the biggest problem．It was a lot like crossing a major highway back in the United States．The streets here were wide，so crossing took time，skill and a little bit of luck．
I finally made it home．The feeling on the bicycle was amazing．The air hitting my face and going through my hair was wonderful．I was sitting on top of the world as I passed by places and people．Biking made me feel alive．

21．According to the author，why are bicycles still popular in China today？A
A．Because they are convenient and inexpensive．
B．Because they are traditional and safe．
C．Because they are colorful and available．
D．Because they are fast and environment friendly．
22．The author decided to buy a bicycle because he intendedB．
A．to ride it for fun．
B．to experience local culture．
C．to use it for transport．
D．to improve his riding skills．
23．How did the author feel about his street crossing？A
A．It was difficult．
B．It was boring．
C．It was lively．
D．It was wonderful．

16．There are many simple，powerful phrases we use．"I love you"is a big one．"I'm sorry"is another．"I forgive you"is powerful for both the speaker and the recipient（接受者）．But the phrase that can change the way we relate to others and the way we view the world has become unpopular："I need your help"．
When we acknowledge our need for help，we go beyond just connecting with others； we show our needs and allow ourselves to receive．Why is this so hard？It isn't just our own skills or strengths that help us survive and bounce back from difficult times； it's also making the choice to reach out to others．
It's easy for most of us to give．It feels life affirming to help others，to give of ourselves．But asking for help and being willing to receive help from others is much harder．When we take that risk-the risk that the answer might be rejection，or unwillingness to help---we are not being weak．We are being vulnerable（易受傷害的），which is perhaps our greatest untapped strength．
Life is never"stress-free"； we all have those times that seem particularly overwhelming，where we get so tired that the word"tired"just doesn't do it justice anymore．These are the times when it seems hardest to reach out，and these are the times when we need to do it the most．
When we ask for help：
★We are choosing to trust the person we ask for help； this shows our respect for him/her．
★We are using our resources wisely．It is a wise person that chooses to ask for help before a problem is out of control．
★We are helping to break down this idea of asking for help as weakness．

28．What can we learn from Paragraph 1？D
A．Phrases can be powerful when used correctly．
B．We should use powerful phrases more often．
C．People don't need as much help as before．
D．People don't tend to ask for help today．
=29．What does the underlined sentence in Paragraph 2 mean？B
A．Life is a matter of choice．
B．Asking for help is very important．
C．It's actually very easy to ask for help．
D．We need a lot of skills to survive hard times．
30．Which of the following statements would the author agree with？C
A．Showing our weakness is our strength．
B．Offering help is harder than asking for help．
C．People are usually willing to offer help．
D．We should be ashamed of being vulnerable．
31．What does the author mainly want to show in the text？A
A．Asking for help when necessary doesn't mean weakness．
B．Today's people love depending on themselves．
C．We should do our best to help others in need．
D．It's not a bad idea to show our weakness．
