题目内容

13．A computer can only do ________ you have instructed it to do．（　　）

A．

how

B．

after

C．

what

D．

when

分析计算机只能做你指示它做的事情．

解答 C 考查宾语从句．分析提干信息可知you have instructed it to do是动词do的宾语从句，宾语从句中to do没有宾语，连接词应该用what引导，what在从句中做do的宾语，所以答案选C．

点评宾语从句属于名词性从句中的一种，也是学生们需要掌握的一种基本的英语句型，引导名词性从句的连接词选择是考试的重点，学会分析从句的句子成分是解决名词性从句的解题关键．

18．Do you know of anyone who uses the truth to deceive （欺骗）？When someone tells you something that is true，but leaves out important information that should be included，he can give you a false picture．
For example，some might say，"I just won a hundred dollars on the lottery （彩票）．It was great．I took that dollar ticket back to the store and turned it in for one hundred dollars!"
This guy is a winner，right？Maybe，maybe not．We then discover that he bought  $200 worth of tickets，and only one was a winner．He's really a big loser!
He didn't say anything that was false，but he left out important information on purpose．That's called a half-truth．Half-truths are not technically lies，but they are just as dishonest．
Some politicians often use this trick．Let's say that during Governor Smith's last term，her state lost one million jobs and gained three million jobs．Then she seeks another term．One of her opponents says，"During Governor Smith's term，the state lost one million jobs!"That's true．However，an honest statement would have been，"During Governor Smith's term，the state had a net gain of two million jobs．"
Advertisers will sometimes use half-truths．It's against the law to make false statements，so they try to mislead you with the truth．An advertisement might say，"Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache．"It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company．
This kind of deception happens too often．It's a sad fact of life：Lies are lies，and sometimes the truth can lie as well．

5．Clara Barton，founder of the American Red Cross，gained worldwide honor for her devotion to easing human suffering and earned the nickname"Angel of the Battlefield．"
     Barton was born into a liberal freethinking family in 1821．Her elder brothers and sisters happily taught her in math and reading，so when she entered school at three years old，she could read and spell simple words．（36）G
     Concerned about Barton's difficulty in making friends，her parents sent her to a boarding school，hoping it would make her more comfortable with her peers．（37）BBarton lost her appetite and cried constantly．After only one term，she had to be brought home．Then，Barton stayed out of school to nurse her older brother through a serious injury and also volunteered to care for poor families during a smallpox（天花）outbreak．
      In 1861，the Civil War broke out．The sight of wounded soldiers touched Barton deeply．She began to collect and distribute food，bandages，medicines，and other supplies for the Union army．

2．FOR most people，life without plants is unimaginable．They feed us，clean up our air and brighten up our gardens．But what if someone told you that even our smartphones can benefit from plants？
Meet the scientists from the Freiburg University of Mining and Technology in Germany．According to reports from Reuters，they have come up with a way to take the important element germanium （锗） from plants．
The element was first discovered in Germany （hence the name） and was used to develop the first transistor （晶体管） because it can transport electricity very quickly．Nowadays，silicon-germanium alloy （硅锗合金） plays an important role in making computers，smartphones and fiber-optic cables （光纤电缆）．
Although germanium can be found in soil around the world，it is difficult to extract （提取）．In the traditional process，people take the material after zinc （锌） mining or burning coal．But the Freiburg scientists decided to fall back on the natural world．
Biology professor Hermann Heilmeier is one of the scientists who are using common plants for this uncommon process．"Different energy crops are being planted，for example，sunflowers，corn…we want to use them for phytomining．In German we call it‘mining with plants'．"
Others have used this method in the past with metals like gold and copper （铜）．But in their study，the Freiburg scientists brought germanium from the soil into the roots and shoots of the plants，harvested them and then took the element from the plants．The process did not cost too much because germanium can be taken after plants are processed for use as biogas （沼气）．So many of the costs are already covered in existing biogas plants．
However，there is still a lot of work to do before we can all experience the benefits．At the moment germanium can only be harvested in very small amounts，just a few milligrams per liter．Now scientists are working on different plants to improve this．
"As is so often the case，industry is still waiting because they want to see everything already working．Then they say，‘We'll have it．'But of course we have to complete the step in between first，"said Professor Martin Bertau，head of industrial chemistry at Freiburg University．

67．We can learn from the article that germaniumB．
A．is mostly produced in Germany
B．can effectively transfer electricity
C．exists mostly in soil and water
D．is very easy to get from nature
68．What can we conclude from the article？D
A．Germanium can be easily produced during the process of mining zinc or burning coal．
B．Sunflowers and corn are currently the most efficient plants to use when extracting germanium．
C．The process of harvesting germanium from plants isn't costly because after harvesting，the plants can be used for biogas．
D．The new method for extracting germanium that the Freiburg scientists are trying is greener and cheaper than the traditional one．
69．According to the article，phytominingC．
A．is a completely new method for extracting metals
B．has been widely used in extracting all kinds of rare metals
C．has different productivity depending on the type of energy crop
D．is now being tested on types of plants that it has never been tried on
70．Which of the following statements would Professor Martin Bertau agree with？D
A．Many businesses have already started contributing money to this research．
B．Industry and science have stronger and closer connections than is generally expected．
C．People from related industries showed no interest in extracting germanium from plants．
D．Germanium has to be extracted from plants in large quantities before this type of extraction becomes industrialized．
