IN the famous fairy tale, Snow White eats the Queen’s apple and falls victim to a curse; in Shakespeare’s novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pills that contained mercury, believing that it would make them immortal, but they died afterward.
Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, the Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Aug 2014, reported The New York Times.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren’t much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad (蟾蜍), the leaky batteries in the trash or the dirty pond water that did it.
“Poisons can be bad for some things,” Michael Novacek, senior vice president of the museum, told NBC News. “Yet they can also be good for others.”
This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment.
The blood toxins of vampire bats, for example, can prevent blood from clotting (凝结), which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances that we regularly take in – chili, coffee and chocolate, etc. – owe their special flavors or stimulating effects to chemicals that plants make to poison insects.By mentioning Snow White and Romeo at the beginning of the story, the author intends to____________.

My husband’s niece is 13 and what I would call “a handful”. She wants to stay with us for while, and her mother and grandmother have told me what a great influence I would be on her.

I don t feel comfortable hosting her, but I don 3r know how to tell my husband’s family members without hurting their feelings.
-Reluctant Aunt
Dear Reluctant,
Let’s get you out of this mess. Your husband’s family is making a request that borders on a demand and sugarcoating it with self-serving flattery (恭维）• Put your foot down, and tell the truth. Say you don’t feel equipped or comfortable hosting the little darling, and regretfully decline (拒绝).Under no circumstances should you take part in any discussion that attempts to change your mind through flattery.

Dear Mindful,
Lighten up! Your older stepdaughter is a considerate and generous sister who covers for and protects her younger sister. Good for her! The girls’ relationship is between them.

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another device out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.
“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time ，and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.
While it，s probable that Apple is definitely in a testing stage for its next smartphone , consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.
“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.
When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored devices when it revamped(更新，翻新）its iPod line last fall, so it’s not too much of a stretch to believe it would want the new twist with its smartphone, as well”.
“I wouldn’t be surprised if the new iPhone becomes available in some new colors，’’ he said. “That could be done pretty cheaply ，and it would give Apple a new marketing angle.”According to Ramon Llamas, Apple always______.
| A．tries to pleases its investors |
| B．does things as planned |
| C．ignores the fierce market competition |
| D．rushes to put new products to market |
As for the next iPhone, Colin Gibbs didn’t mention______
| A．the stage of its being tested |
| B．the rough time of its being released |
| C．the wide variety of its color |
| D．the function to be improved |
What’s Colin Gibbs ，attitude towards the next iPhone?
| A．Disapproving. | B．Casual |
| C．Objective. | D．Doubtful. |
This passage is presented in the form of______.

Tre’S mom，Christina Thompson, cannot believe how much her son already learned this year in his full-day, free pre-school class in Oklahoma City. “Since he’s been in school his vocabulary has increased surprisingly,” Thompson says. “The other day he came home and said, ‘You know what ，mom? You are being ridiculous，” Thompson laughs quietly. “And then he asked, ‘Do you know what ‘ridiculous’ means, mom?’” Tre knows the entire alphabet, his numbers to 100，and he’s starting to read. And letters and numbers aside, Thompson is most struck by how fast Tre is absorbing vocabulary and language.
Of course, not all pre-school is created equal. High quality pre-schools have well-trained, well-educated teachers in the classroom (much like Tre Thompson’s teacher Mrs. Wallace, who uses play-based learning to teach both academics and social skills and can rattle off (飞快说出） a battery of data on how well her students are progressing towards their year-end goals). Texas can also offer a model for educator development: its Texas School Ready! Campaign has proven to increase the quality of participating pre-schools by providing early childhood teachers with coaching, professional development, research-based curriculum (课程)，and progress monitoring. States and districts should also combine pre-school with the K-12 system, as Oklahoma does ，so that children enter kindergarten smoothly.
Oklahoma is one of the leading states in providing students like Tre with free ，full-day pre-school. And the results are already paying off: According to a 2012 study, Oklahoma kids that went through pre-school showed vocabulary gains 28% higher than those of children without pre-school, and math gains 44% higher than non-pre-school kids. And we know that high-quality pre-school doesn’t just mean higher scores in elementary school. They were more likely to have graduated from high school and less likely to have committed a violent crime. They also earned more money and were more likely to be employed.
We know pre-school works, so let’s stop talking and start building a system where all children have access to excellent early childhood education. As any well-educated four year old could tell us, not doing so would be ridiculous.The case of Tre in the first paragraph serves as the evidence of______.
| A．children’s disrespect towards parents |
| B．the bad performance of students at school |
| C．the positive effect of pre-school on children |
| D．Thompson’s doubt about her son’s education |
At high quality pre-schools, children may learn by______
| A．playing | B．modelling | C．researching | D．monitoring |
It can be inferred that______.
| A．children can not enter kindergarten without pre-school |
| B．Oklahoma is the best state offering full-day pre-school |
| C．all pre-schools have well-trained, well-educated teachers |
| D．kids with pre-school may be better equipped for their future |
What would be the best title for the passage?
| A．Not all pre-school works |
| B．All pre-school is created equal |
| C．We owe our kids universal pre-school |
| D．Pre-school goes well with K-12 system |
Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.Which of the following is most likely to lead to less groundwater?
| A．Using river water. | B．Throwing batteries away. |
| C．Paving parking lots. | D．Throwing rubbish into lakes. |
What can be inferred from the text?
| A．All water shortages are due to human behavior. |
| B．It takes a lot of effort to meet our water needs |
| C．There is much we can do to reduce family size. |

The last paragraph is intended to .
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
The text is mainly about .
| A．how human activity affects our water supply |
| B．how much we depend on water to live |
| C．why droughts occur more in dry climates |
| D．Why paving roads reduces our water |
The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
Finding：A full 33% of seniors brush their teeth only once a day.
Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush.
Brush gently for 2 minutes, at least twice a day.
