17．To his mother's disappointment，the boyaddicted  himself to playing online games．（沉迷）

分析 讓母親失望的是，那個男孩沉迷于玩網(wǎng)絡游戲．

解答 addicted，考查固定搭配addict oneself to sth．"使某人沉迷于…"，句子表示動作發(fā)生了，因此使用一般過去時．

點評 對于翻譯填空這種題，要分析句子意思，再從結構上和意義上對答案進行確定．

5．As part of an effort to improve treatments for life-threatening illnesses，a team of scientists have created rabbits that glow in the dark．
Their efforts have produced two rabbits out of a litter of eight that went from being a normal，soft white to glowing green in the dark．The rabbits were born at the University of Istanbul as part of the collaboration between scientists from universities in Turkey and Hawaii．
The rabbits glow to show that a genetic operation technique can work efficiently，though the specific color is more cosmetic than scientific．"The green is not important at all-it's just a marker to show the experiment can be done successfully，"said University of Hawaii associate professor，Stefan Moisyadi．
To produce the glowing effect，researchers injected jellyfish（水母）DNA into a mother rabbit's embryos．Then those embryos were inserted back into the mother．Similar experiments have resulted in glowing cockroaches（蟑螂）and cats．
Eventually，the researchers hope the technique can lead to new ways to produce medicines，Moisyadi said．
"The final goal is to develop animals that are able to produce beneficial molecules（分子）in their milk that can be cheaply extracted（提�。琫specially in countries that cannot afford big factories that make drugs，which  usually cost US $1 bn to build．Then they will be able to produce their own protein-based medication in animals，"Moisyadi said．
The rabbits are expected to have the same life span as their non-glowing counterparts，but Moisyadi said he understands people can object to this kind of experimentation involving live animals．
"To the people against，I say：think about，what are the benefits and what are the injuries？"Moisyadi said．"And if the benefits outweigh the injuries，let's go with the benefits．"
Moisyadi，a native of Turkey who is now with the University of Hawaii，started developing the project in 2006，and researchers are now waiting to see if pregnant sheep produce similar results．
31．What do we know about the glowing rabbits？D
A．They live shorter lives than ordinary rabbits．
B．Their fur became green after the experiment．
C．They were chosen from a special species of rabbits．
D．The color that they glow isn't of interest to scientist．
32．Why did scientists conduct the experiment to create glowing rabbits？C
A．To research  animal genes．
B．To improve animal species．
C．To produce cheap，beneficial medicine．
D．To improve animal's ability to resist disease．
33．Which animal wasn't used as the test subject？C
A．The cat．B．The jellyfish．C．The sheep．D．The cockroach．
34．Which of the following is TRUE，according to the passage？C
A．The project is supported by people．
B．The success rate in creating the rabbits is 20%．
C．The project has been conducted for more than nine years．
D．The project is mainly conducted by Turkish scientists．
35．What is Moisyadi's attitude towards such experimentation？B
A．Doubtful．B．Supportive．C．Disapproving．D．Indifferent．

Falling
You're falling，falling，falling…and then you wake up．Thi s dream is said to mean you are afraid of something or worried about something．There may be something in your life that is out of control and there is nothing you can do to stop it．Another explanation is that you may experience failure in something．Maybe you're not doing well in school or work．

You suddenly realize you have to take an exam at that very moment．You might be running here and there to find your classroom．Experts say this dream may mean you're being tested about something or maybe you are facing a challenge．
Flying
Dreaming that you are flying means you are on top of things．You are in control of the things that matter to you．It may also mean you have confidence in yourself and think no one and nothing can beat you．
Trying to run，but going nowhere

6．Last month，I （33）reutrned（return） to Australia to attend my elder sister's wedding．Although it was a very modern wedding，my sister kept one tradition （34）that/which comes from an old English poem．
The poem says that a bride must wear："Something old，something new，something borrowed something blue．"It is said （35）to bring（bring） good luck to the marriage．
Something old is （36）something passed on from the bride's family．It could be an heirloom（傳家寶）that has been in the family for years，or a piece of her mother's dress．This is meant to show a connection （37）with the bride's family．
Something new brings hope for the future of the couple．It can be the new wedding dress，or new shoes．
Something borrowed is normally （38）an item of clothing or jewelry borrowed from one of the bride's friends who have a happy marriage．It is believed to bring some of the friend's luck from her marriage to the bride．

7．Ways to save time
We all wish we had just a bit more time．Just think what you could do with an extra hour or two each day：you could finally stick to an exercise routine，or spring-clean the house，or write your novel，or learn the guitar and so on．
（16）D  But I can help you find more hours in your day for the things that really matter．
★Get Out of Bed Earlier．
If you normally get up at 7； 30 a．m．try getting up at 7：00 a．m．That half-hour might not sound like much，but it could be time that you use to exercise，to read that book you've been meaning to finish．（17）E   
★Do the Important Tasks First．
Once you get to work，get the important ones done first（not the easy ones，or even the urgent ones）．（18）GIf you work like this，you'll usually save time．The urgent tasks will still get done，and you won't miss the important ones．
★Reduce Interruptions．
If colleagues have a habit of hanging around your desk to chat，or if the phone is constantly ringing，you might find that it takes you half the day to finish a simple task like writing a letter．（19）F 
★（20）A
A few minutes chatting，browsing the web，and so on，can easily turn into hours of wasted time over the course of a day．If you concentration is slipping，take a proper break：go and get a glass of water，or stretch your legs a bit．And if you're facing a difficult task，try breaking it into small steps or stages so that it's easier to deal with．

A．Stay Focused on Your Work．
B．Take Breaks When Necessary．
C．Would you want me to make your day longer？
D．I can't magically make all your days 25 hours long．
E．Or simply to get your day off to a calm and organized start．
F．Constant interruptions don't just eat up time，they also break your concentration．
G．You can afford to spend at least an hour working on big，important tasks rather than on all those little urgent ones．
