5．The yield of the new rice is much greater than               of other types of rice grown in Pakistan．（　　）
A．oneB．thatC．itD．what

分析 這種新稻子的產(chǎn)量比在巴基斯坦生長的其它類型的稻子高．

解答 答案是B．本考查代詞的用法；than后面沒有謂語動詞，不是句子，不能用what引導的從句，排除D；one是泛指其中之一；相當于"a+單數(shù)名詞"，指代上文同類中的一個；that是特指；相當于"the+不可數(shù)名詞或單數(shù)名詞"；特指與上文同類；it指代上文提到的單數(shù)名詞或不可數(shù)名詞本身；題干中需要的代詞代替"the yield"；特指與上文同類"其它類型的稻子的產(chǎn)量"，故選B．

點評 代詞的考查要根據(jù)語境分析需要的代詞代替上文中的哪一部分，然后根據(jù)被指代的這一部分的特征判斷答案．

13．I've learned that you have to make the choice if you want to get anywhere．If you just let other people decide what is going to happen for you，then all your goals and dreams may never be achieved．
Everyone always says that studying abroad in college can change your life．I made the decision to experience it for myself during my junior year．I chose to study in the Dominican Republic．As it got closer to the deadline，an advisor told me I had received a scholarship from an alumni （校友） family foundation．
During my first semester in the country I fell in love．I was becoming bilingual （雙語的） but also learning so much about a new culture．I had begun working with a local grassroots organization，taking part in a project supporting an underdeveloped community just outside the city．My main role was to become aware of the issues facing populations such as these and support community education．I was in no way ready to leave this new life．I felt as if I needed more time to get what I wanted．
As the next semester began，I realized again that I needed to take a chance．I got involved with a local boarding school for girls living in poverty．I first approached the head of the school to volunteer to teach music classes，asking for money from my college church．I could have never predicted the results of this small action．Another volunteer and I were able to put together a benefit （義演） to show off what the students had learned．We invited community members，friends and other students from local universities to support the girls．We also sold art that the students themselves had created to increase the funding （資助） of the arts program．I felt good when I left，knowing that I had laid the foundation for a good cause and bettered the lives of young girls．
There will always be people that think they know what is best for you，but you ultimately know what you want in life．My time in the Dominican Republic changed my life by giving me the realization of how fortunate I am and the fact that there is always a chance to give back．You have to go after anything and everything you desire or there may be a missed opportunity．My trip to Santo Domingo taught me to take advantage of new possibilities．

67．The article mainly tells usB．
A．how the author helped poor girls in a local boarding school
B．that studying abroad gave the author life-changing opportunities
C．that the author chose to study abroad to follow other people's examples
D．how the author learned about the issues facing people in the Dominican Republic

A．started a project in a developed community
B．couldn't fit in well with the school or life there
C．was unsure if she should stay for another semester
D．became absorbed in a new culture and a new language
69．From Paragraph 4，we can learn thatD．
A．the author organized events to raise money all by herself
B．the author set up an organization with the funding of her college church
C．the author worked as a music teacher in her college
D．the results of the voluntary work were beyond the author's expectations
70．We can infer from the last paragraph that the authorB．
A．think other people know what is best for us
B．is grateful for her experience in Santo Domingo

10．It is promoted that we should all prioritize some simpler life improvements to live better lives．The explanations for how and why they better our life serve as powerful reminders that we might be prioritizing the wrong things，and undervaluing what makes life worth living．
Smoking drinking，exercise and even heart problems are not predictors of a person's longevity-a person's close relationships and social integration are．Our human connections have the positive impact on all aspects of our well-being，including our physical health．Those with intimacy（親昵）in their lives，and those with frequent face-to-face interactions were not only physically and emotionally healthier，but they also lived longer．
It's why women，who tend to prioritize spending time with their friends more than men，live an average of six years longer．It's not enough to text or email．The actual health benefits of socializing are only achieved through in-person contact because face-to-face contact releases chemicals that protect you now and well into the future like a vaccine．
People who spend time on social networks，dating apps and even online news sites are found less happy．Most things we do for pleasure，like reading a book or watching a movie，have an end．But scrolling（卷動）on the phone is endless and we don't know when to break away．And those who do set limiting rules for their technology use are able to enjoy life more．Life becomes more colorful，richer，when you have better conversations with the person who is there with you．
The chase for happiness doesn't make us happy．In fact，constantly evaluating our own happiness is actually contributing to feelings of hopelessness and depression．Happiness is a fickle（變幻無常的）emotion，based on a moment or an experience．It's not a lack of happiness but lack of meaning that's really making us feel sad．
Meaning can be obtained in four forms：belonging，purpose，transcendence （卓越）and storytelling．The first is having people in your life who truly love and care about you．The second is having purpose．Most people find purpose through work because it's how we feel like we're adding value or contributing．So finding something to drive you forward is a crucial slice of having meaning．Transcendence is about finding something like art or church or doing yoga that can take you outside of yourself，that can make you feel like you're part of something bigger．With storytelling，that's all about our personal narratives．We're the author of our stories，and we can change how we're telling them．Your life isn't just a list of events．
In order to live longer and more happily，we should prioritize the（71）right/correct/proper/appropriatethings．
Face-to-face social interaction（72）predicts/indicates/means/promisesa longer life．Our close relationships and social integration（73）improve/better/polishour mental and physical health．
Women live six years longer than men on average because of more（74）communication/talks/socialization/conversations/interaction（s）with their friends．
Face-to-face contact produces chemicals that（75）function/serve/actas a vaccine．
Knowing when to turn off our smart phone enriches our life．Most entertainments have an end but using the smart phone is an（76）exception．
Life becomes more enjoyable when we limit the（77）useof mobile phones．
Chasing meaning，not happiness，is what really（78）matters/counts．We will find our life more meaningful by developing a sense of belonging．
It is vital to find a（79）purposeto drive us forward，which will add meaning to our life．
Things like art and church help us go beyond usual limits and feel you are（80）important/something/somebody．
We should tell our own stories in a creative way to inspire ourselves．
