One night there was a tarible snowstorm in the mountains. During the snowstorm, Mrs Albina gave birth to triplets,a boy and-two girls!The oldest Albina children are in their thirties and forthies. They are on their own now, but 18 of the Albina children still live with their parents The fa:mily lwes in a two-room shack in Colina Chile The shack has electncity but no toilet or running water The children wash in a small bowl in the dusty backyard.At times there is very little food in the Albinas’ small house When thcre is not cnough foodfor everyone, Mrs Albina makes sure the youngest children do not go hungry.

The reason for this is to gwe children healthier food. There are many foods that children aren’t allowed to eat and they’re only allowed to eat small amounts of fatty or sweet food. If you were at a school there, you might hear this conversation as you wait for your lunch.Josh:Whats for lunch? I want chips.Dinner lady: No chips today. You’ve had chips twice this week already.Josh:Oh! OK, I’ll have a chicken pie with gravy.Dinner lady: No, sorry. You’ve had a pastry dish (油酥食品) once this week already.Josh: Really!Oh yes, on Monday. Well, what can I havel? I’d like pasta an d sauce.Dinner lady: No, sorry. Pasta counts as (算作)a pastry dish So you can’t have that, either.You ‘ve had two pastry dishes this week - a meat pie and a pizza. You can have vegetables or salad. The meatballs are nice today.J osh:All right. I’ll have meatballs and steamed vegetables. I hope they’re tasty.Dinner lady: They’re good for you!Josh:I miss my chips They’re my favorite. I used to have them every day. Before these new rules came in.Dinner lady: Well, that’s wh y these rules were brought in. Too many children were eating junk food, especialy chips. Children like chips, but they aren’t a healthy choice.J osh:I’ll have an apple juice with that, please.Dinner lady: OK, but its only 150 ml. You aren’t allowed more than that as juice has sugarin it. The new rules encourage you to drink water. No soft drinks at all.Students cannot have more than two portions (价额)a week of food that has been deep-fired.They must have at least three different fruits and three different vegetables every week. Whole grains such as brown bread are to be given,instead of "white" grains.These rules are to teach healthy eating and to stop children putting on too much weight. This will make sure that more people are healthy in the future.6. The new rules about gwen lunch are brought in to .A. give cluldren healthier foodB. sell fruit and vegetablesC. help students save money7. What did Josh have for lunch in the conversation?A. Chips.B.

It can also be a gas, when it evaporates (蒸发) and become water vapour (水蒸气) .The water cycleWater is very important, and without it life on Earth should be impossible. The oceans thatcover three quarters of the Earth’s surface can be thought of as our great water reservoirs. All thetime, water is being evaporated from the ocean’s surface by the warmth of the sun. High in the sky this water vapour, turns into clouds which drift (漂浮) over the land, often creating rainfall. As the rain falls,it seeps (滂漏) into the soil and then into rivers that flow back into the oceans, where it is ready to begin all over again!下而是被打乱的有关The water cycle（水循环）的信息，请根据短文内容重新排序。

语鹅市安置阳光实验学校阅读理解主旨大意题专练(三) 段落大意类A(2017·烟台诊断)Grandparents who help out occasionally with childcare in their community tend to live longer than seniors who do not care for other people, according to a study from Berlin, Germany.“Having no contact with grandchildren at all can negatively impact grandparents' health. This link could be deeply rooted in our evolutionary past when help with childcare was important for the survival of the human species，” said Sonja Hilbrand, one of the researchers.The findings are drawn from data on more than 500 people over age 70. Overall, after accounting for grandparents' age and general state of health, the risk of dying over a 20year period was onethird lower for grandparents who cared for their grandchildren, compared with grandparents who provided no childcare.Caregiving was associated with a longer life even when the care receiver wasn't a relative. Half of all childless seniors who provided support to friends or neighbors lived for seven years after the study beg an, while nonhelpers lived for four years on average.“Caregiving may give caregivers a purpose of life because they may feel useful for others and society. Caregiving may be thought also as an activity that keeps caregivers physically and mentally active，” said Professor Bruno Arpino.Arpino noted, however, that caregiving is not the only activity that can improve health and that too many caring responsibilities can take away from other beneficial activities like working, being in social clubs, or volunte ering. “Children should take_into_account their parents' needs, willingness, and desires and agree with them on the timing and amount of childcare，” he suggested.“It is very important that every individual decides forhimself/herself, what ‘proper amounts of help’ means，” Hilbrand said, adding, “As long as you do not feel stressed about the intensity (强度) of help you provide you may be doing something good for others as well as for yourself.”体裁：议论文题材：社会文化主题：祖父母适当照顾孙辈对身体有益【语篇导读】德国柏林一项研究发现，祖父母适当地帮忙照顾孙辈比不照顾孙辈的老年人寿命长。

(15分)It was the last evening of the old year. In thecold and darkness there went 31 the street apoor little girl,with bare feet.She carried a small bundle of matches in herhand,and a lot 32 in her broken apron (围裙).No one had bought any all day long. Trembling withcold and hunger, the girl walked on and on. 33poor little child!In corner,she sat down, but she could not warm herself. She was 34 to go home. she had earned(赚)not a coin,and perhaps her father would 35 her，and her home was almost as cold as the street. Her hands were nearly dead with cold. She struck one match against the wall, and held her hands 36 the flame(火焰).She wanted to warm her small hands. It was quite a magic light. She found herself 37 before a large iron-stove. How warm it was! As the child wanted to warm her feet, the flame 38 ，and the stove disappeared. The little girl sat coldand hungry,with the burnt match in her hand.A second match was lighted. She saw a table 39 delicious food. The roast goose stood at one end,with knife and folk in her breast, jumped down from the dishes,and came to the poor child. The match was burnt out and only the thick, 40 wall was beside her.She struck 41 match, this time, her gentle and loving grandmother came up, bright and happy as she had never looked during her lifetime.“Grandma!”42 the child, “Oh. take me with you! I know that you will leave me43 the match goes out.”And she lighted all the matches hurriedly;she would like43 her old grandmother disappearing. Her kind, old and beautiful grandmother took the little girl in her arms,and they both flew high together, until they were in that place where neither cold, nor hunger, nor 45 is ever known.The next morning, the little girl was found dead in the corner, with a smile on her face.31.A.away B. along C. off D. out32.A.many B. much C. most D. more33.A.What a B.What C.
