I want to share with you a true story, happened a couple of days ago. One of my classmates bought a bag of snacks from a food store. A few roommates were then invited to enjoy snacks. Unluckily, all of whom got poisoned and had stomachaches with our faces pale. They were quickly sent to a nearby hospital. Doctors examined them but gave them some medicine. They were out of danger soon before taking the medicine. This accident should make us to realize the serious of the food safety problem. I strong suggest that the whole society pays more attention to food safety.

【答案】

【1】happened--happening

【2】enjoy后面加the

【3】whom--them

【4】out--their

【5】but--and

【6】before--after

【7】 us后面to去掉;

【8】serious--seriousness

【9】strong--strongly

【10】pays--pay

【解析】

试题分析:文章介绍作者的同学误食了不安全的食品,食物中毒的事情

【1】happenedhappening 考查非谓语动词。句意:我想跟你分享个真实的故事,发生在许多天前。Happening表示伴随;

【2】enjoy后面加the 考查冠词。一些室友被邀请享受这个零食。这里是特指上文提到的零食,是特指

【3】whomthem 考查代词。句意:不幸地是,他们所有人都中毒了,伴有胃疼和脸色苍白。

【4】ourtheir 考查代词。不幸的是,他们都中毒了,伴有胃疼和脸色苍白。因为是作者的同学们,用their

【5】but--and 考查连词。医生给他们做了检查,给了他们一些药。这里表示并列关系。用and。

【6】before--after 考查连词。句意:吃药之后他们脱离危险;

【7】 us后面to去掉; 考查动词的用法。这个事情让我们意识到食品安全的重要性。Make sb do 让某人做某事;

【8】serious--seriousness 考查名词。句意:这个事让我们意识到食品安全的重要性。The后面加名词;

【9】strong--strongly 考查副词。句意:我强烈建议整个社会重视食品安全。Strongly用来修饰动词suggest.

【10】payspay 考查动词的时态。Suggest当建议讲,宾语从句用(should) +动词原形;

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。

Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule,protecting them from the body-and the body from them-until they can be released at just the right spot. There are lots of ways to trigger(引发)this release,including changing temperature,acidity,and so on. But triggers can come with their own risks-burns,for example. Now,researchers in California have designed what could be a harmless trigger to date:shining near-infrared light(NIR,近红外线)on the drug in the capsule.

The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers(聚合物)and other materials that begin to break down when they absorb either ultraviolet(UV,紫外线)or visible light. But tissues also readily absorb UV and visible light,which means the drug release can be triggered only near the skin,where the light can reach the capsule. NIR light largely passes through tissues,so researchers have tried to use it as a trigger. But few compounds(化合物)absorb NIR well and go through chemical changes.

That changed last year when Adah Almutairi,a chemist at the University of Califomia,San Diego,reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIRabsorbing group called onitrobenzyl(ONB).When they catch the light,ONB groups fall off the polymer,leading to its breakdown. But ONB is only a so-so NIR absorber,and it could be poisonous to cells when it separates from the polymer.

So Almutairi and her colleagues reported /span>creating a new material for capsules that's even better. This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive(易反应的)components that make it highly unstable in its polymeric form,a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols,they cap each reactive component with a light-absorbing compound called Bhc. When the Bhcs absorb NIR light,the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown,potentially releasing any drugs in the capsule. What's more,Almutairi says,Bhc is 10 times better at absorbing NIR than is ONB and is not poisonous to cells.

【1】According to the passage,which of the following could be the best trigger?

A.Temperature change.

B.NIR light.

C.Acidity change.

D.UV light.

【2】Why is ONB unsatisfactory?

A.It breaks down when it absorbs NIR light.

B.It falls off the polymer and triggers drug release.

C.It has not come onto the market up till now.

D.It is not effective enough and could be poisonous.

【3】Which word can be used to complete the following process of changes?

A. protected

B.formed

C.exposed

D.combined
