Article: Earth is the third planet from the sun.It is one of the four inner planets.The other three inner planets are Mercury,Venus,and Mars.The inner planets are also called the rocky planets,because they are made of rocks. Earth is often called the "Water Planet",because it is the only planet in our solar system which has liquid water on its surface.About 70% of the surface of Earth is covered by water! The other part of Earth is made up of continents and islands which have different landforms on them.Examples of landforms are mountains and plains.Plants and animals can live on Earth,because it has so much water. Earth spins very quickly compared to other planets.It only takes Earth 24 hours to spin around its axis one time.One Earth day is 24 hours long!Earth orbits the sun in 365 days! This makes one Earth year 365 days long! Earth is the only planet in our solar system where humans,other animals,and plants can live.There is plenty of water to drink or to live in.Water is present on Earth in its big oceans and in the air! Clouds are made of water vapor.The atmosphere has a lot of oxygen in it for animals to breathe,but the rest of our "air" is made up of water vapor,nitrogen,carbon dioxide,and other gases.The air is perfect for plants to grow.Earth temperature is not the same in all places,but the temperature is just right for plants,animals,and humans in most places on Earth. Like the other inner planets,Earth has volcanoes.Volcanoes on Earth are different from those on other planets,because they still erupt.Scientists think that there may be active volcanoes on other planets and moons in our solar system,but they are still studying this. Earth has one planet which we call the Moon.The surface of the Moon has many craters on it These were caused when meteorites hit it.It has many volcanoes on it which do not erupt anymore.We can see the moon at night without using a telescope.It is the closest space object to our planet,Earth. Question: Life exists on Earth, _ . Yes or no, is the answer "because the water,air,and temperature are just right"?
Yes

Article: Here is a passage about learning a foreign language. Outside of class, the most natural way of finding out if you are making mistakes is from other people's responses. If the mistakes are too serious, your listeners will be asking you all the time what you mean. If they are not so serious, then people may be asking you whether you said such and such. That will tell you how close you are to speaking "cogently". Of course, there are other times when it is important to have errors pointed out. Your class assignments are probably marked in this way, in which case you need to spend time going over them to take advantage of the individual feedback. In some classes the teacher gets better and better at grammar because she does all the corrections, but the students make slow progress if, when an assignment is returned, they quickly stuff it into their folders without looking. You are the person who should be connecting your error, even if the marker has signaled them, when you look at them; there are some steps to work through. One distinction that has been made about learners' language is this. You make mistakes about rules that you already know but you make errors about points you haven't learned yet. In other words, you can find your own mistakes, but not your errors. First, make sure you understand what you have written or said, or your correction will simply be another stab at the right answer. Next, decide on the best way of practicing the correct form. Would it help you to write out the sentence once more? Can you make up another similar sentence? Then you could test yourself in a few days time to see whether you have remembered the right form, anyone can get it right immediately after being told. He challenge is to remember it and apply it later. Question: Which of the following might be the most important to work through your mistakes? Yes or no, is the answer "Keeping the right form in mind and using it later."?
No

Q: Article: You'd be forgiven for thinking that running after children each day would leave parents in the best shape of their lives.But a study has found that the mothers and fathers of young children are more unhealthy than their childless peers . Mothers with young children are heavier and eat more calories and fatty foods,and consume more sugary dinks than chidless women,scientists said.And both sexes are less active than those in their age group without children. Parents often choose quick,easily preparesd foods that are high in fat and calories,and by choosing these foods they may in turn serve them to their children,forming a cycle of unhealthy diet. Dr.Berge,one of the study authors,said:"This isn't a study about blame,this is about spotting a very high-risk time period for parents that doctors should be aware of ,so they can offer solutions ." According to the study ,mothers ate more fatty foods and drank about seven sugary drinks weekly,equal to about four chidless women.They also had an average of 2,360 calories daily,368 calories more than women without children,With that many calorise,women that age would need to be active to avoid to avoid gaining weight. Fathers ate about the same amount of daily calories childless men and both had an average boby-mass index ,but fathersgot less physical activity--about five hours weekly ,compared to almost seven hours among chidless men. The study has several limitations-there's no data on how many women reccently had babies.Ther's also no information on the number of single parents,who likely face diet and exercise challenges.Sarah Kriger,an American dietician who works with new mothers said some of the mothers may have had postpartum depression,which might affect their eating and exercise habits. Question: What does the author mainly aim to tell us in the passage? Yes or no, is the answer "Couples of young children eat more fatty foods and lead unhealthier lives."?
A: Yes

Article: China news, Oct. 26--China Great Wall Society's secretary-general Zhang Ji says that the Chinese Academy of Social Sciences (CASS) would join hands with the Society to produce a 3D picture of the Great Wall so that _ could view its original looks. When the website opens, a picture of the revolving earth will appear against the background of the universe. A click on the Great Wall will bring the earth nearer, and slowly a white line is seen across the Chinese land in the north. A closer view shows that this is the Great Wall. Netizens will be able to appreciate the Great Wall with the eye of a tourist and "walk" from Shanhai Pass in the east of the Great Wall to Jiayu Pass in the west in just a couple of days. They can also take a look at the mineral resources and economic status of regions along the Great Wall. CASS and the Great Wall Society are trying their best to make this dream come true through working together closely. According to Zhang, to achieve the above effects, scientists will rely on airborne remote sensing, national geographical information system and global positioning system to collect detailed data of the Great Wall, analyze and process the data, apply them to satellite images for 3D translation, and thereafter create a 3D digital image of the Great Wall for the entire world to appreciate the really great Great Wall of China via the Internet. Question: The 3D picture will be _ . Yes or no, is the answer "made to show the really great Great Wall to the entire world."?
No
