These family recipes are a special part of our family history. People have passed down some of them from generation (一代人) to generation.“I realized I couldn’t go home every weekend for my mom's delicious dishes,” says Shreya. She is about to enter university and has recently started following her mother around the kitchen, taking notes on how to make her special tastes. She adds, “I am looking to the day when my kids will come to know of their grandmothers through the dishes they cooked.”But many of us find it difficult to keep the food connection with our busy life. Even if we have time, not many of us take the effort to collect and record the recipes from our grandmothers and parents. We often get a recipe on the phone and take it down quickly on a piece of paper. We just stick it onto the fridge for a week or two and forget about it as soon as the paper disappears.Actually, there are simple ways to keep family recipes. Scrapbooks (剪贴薄) are easily found in the market. You can even add photos to record every detail of your memories about the recipe. You can also use some popular apps like Story Scans to record family recipes. You just scan (扫描) the recipes and record the story behind each of them. It can become the most meaningful work you have ever done with and for your family.Keeping family recipes is saving and honoring our tradition so that future generations can continue to make family ties stronger. Every time you remember your loved ones, recreate one of the dishes from your collection and let the memories from the good old days comfort you. So why not gift your kids a family recipe book when they are starting a new life?31．Why does Shreya follow her mother around the kitchen?A．To clean up the kitchen.B．To note down recipes.C．To prepare family dinners.D．To talk about family rules.32．What can we learn from the passage?A．Ways to record recipes can be easy.B．Most people like writing recipe books.C．Recipes have become popular with kids.D．People often buy recipe books in the market.33．What does the underlined phrase "take the effort" mean?A．make wishes B．try our best C．would like D．think of ways 34．Which question could best help us find out the writer's purpose (目的)?A．Did the writer make us practise cooking?B．Did the writer tell us how to cook well?C．Did the writer want us to keep family recipes?D．Did the writer teach us how to choose a gift for kids?35．Which of the following would be the best title for the passage?A．Family Recipes: Secrets of Cooking B．Family Recipes Are at a CrossroadsC．Family Recipes: Connections to Interests D．Family Recipes Are More Just Recipes四、多任务混合阅读阅读下面短文，按要求完成下面小题。

There are a lot of reasons why growing your own food is a good idea. GIY helps reduce carbon dioxide (CO2) emissions (排放物). Food in supermarkets travels a long way and that produces a lot of CO2. If you grow as many vegetables as you can at home, you can help save the earth.Vegetables you grow are also good for your health because they have more nutrients than supermarket vegetables and they don’t have chemicals.How much money can you save? First of all, seeds are a lot cheaper than vegetables, and secondly, you can save more by planting the most expensive and the most productive (多产的) vegetables. You can give your vegetables to friends and neighbors. It can make you very popular.Don’t worry if you don’t have much space. To GIY, you don’t even need a garden. You can use pots on your balconies (阳台). And don’t worry if your space doesn’t get much sun. You can plant vegetables that don’t need a lot of sun to grow.Grow your own vegetables now.

Does it seem to you that girls have better language skills than boys? In your opinion, are boys better at building things? If your answer to each of those questions is “Yes,” you are right, according to an article in Current Science." There are exceptions(例外), but here are the facts.Usually, boys score higher on tests about math, while girls do better in tests about words, spelling and memory. But these differences may not always be true. In the future, a person’s abilities may not be decided by sex. As one scient ist says, “Nothing is impossible for a person to be or do.”A recent study by Jerome Kagan, a scientist at Harvard University is studying the watching ability of children 10 months old. Baby boys and baby girls are watching a “show” while seated on their m others’ laps. In Act One of the show, an orange-colored ball is lifted from a blue box and moved slowly. Then it is returned to the box. This is repeated six times. Act Six is almost the same, except that the orange ball is smaller.Baby boys do not seem to notice the difference in the size of the ball, but girls immediately become excited and begin to make noises that sound like language.It’s also known that baby girls usually talk at an earlier age than baby boys do. Scientists believe that the left side of the brain develops faster in girls than in boys. As a result, by the time they start to school, little girls have an advantage that boys don’t have, but what have the boys been doing in the year before starting school? They have been developing something called aggression. An aggressive person feels strong and independent. He is often the first one to start a fight. It is said that aggression is caused by hormones (荷尔蒙). Scientists believe that hormones are not the only cause. They say aggression in boys is also caused by mothers. 31．According to the article in Current Science, what are girls better at?A．Finding facts B．Using language C．Learning science D．Building things 32．Which is right about Jerome Kagan’s study?A．Girls don’t like the show.B．Boys are strong enough to lift a blue box.C．Boys and girls have the same watching abilities.D．Girls quickly notice the difference in the size of the ball.33．Why do girls have an advantage when they start to school?.A．Girls become independent earlier. B．Mothers teach girls more patiently.C．Girls’ hormones develop more completely.D．The left side of the brain develops faster in girls.34．What does the underlined word “aggression” in Paragraph 5 mean?A．An angry feeling. B．A good habit. C．A friendly action. D．A strong person. 35．What is the passage mainly about?A．The research on girls’ advantages.B．The result of school education. C．The differences between boys and girls. D．The children’s abilities to memorize.四、多任务混合问题阅读短文,并按要求完成文后各题。

The brain is divided into two hemispheres（半球）. The left hemisphere is the center of language and logical thinking. This is where they do their math problems and memorize words. However, the 3 hemisphere controls how they understand ideas and 4 they respond（作出反应）to the five senses—sight, hearing, 5 , taste, and touch. The left hemisphere controls the right side of the body, 6 the right hemisphere controls the left side. Both sides of the body receive the 7 information from the brain because they are connected(联系). In right-handed people, the left hemisphere is stronger. In left-handed people, the right hemisphere is 8 .Lefties prefer not only the left hand but also the left 9 . They would rather use the left foot to kick a ball because their whole body is “left-handed”.From Newtown 10 Albert Einstein, Wen Jiabao to Obama, Choplin to Zhao Benshan, many____people areleft-handed.

More than seventy 10．(act) have played the role in over two hundred films!Ⅳ. 阅读理解A13、For years, the word “popular'，has been demonized（妖魔化）and made thesame as mini-skirt-wearing,hair-coloring cheerleader types like Regina Georgein Mean Girls. Today, teachers and parents inform children that being popularis irrelevant（不相干的），unnecessary and a sure shortcut to upset, misery, anddeath. And some people describe popular students as the ones most likely tobum out and end up as nobody, while their less well-liked counterparts enjoy alife of wealth and fame.However, the Oxford English Dictionary defines（定义）popularity as:“TheState or condition of being liked, admired, or supported by many people’ Thissounds like a lovely thing, and is not related to such behaviors as “burn books” or “three-way phonecalls" in Mean Girls．In fact, it is a truth widely acknowledged that young people who feel liked or supported are morelikely to obtain impressive achievements than those who feel lonely, unvalued, and irrelevant socially.So why, then, is popularity given such a bad name? Why is this state of well-likedness so demonized?Basically, the hatred (恨) shown toward what appears to be a very pleasant thing is caused by lackof understanding. When we, as viewers, see characters such as Regina Georges on TV and in films, werecognize them to be popular. These characters, if not exactly liked,，greatly admired by their peers（同伴）．Our mistake comes when we try to understand their cruel and unkind actions using the deduction（推论）method.Humans are imperfect, and even the most intelligent mind is open to dishonesty through a very smallslip in logic. Unfortunately, this occurs here with branding results We first learn that a character is popular. Since this is important to the plot, it is constantlyemphasized, leading itto be the most common thing in our minds when we consider the ter, we see that character do something unkind. The character's most noticeable characteristic (inour minds) is his/her popularity. And now the character is mean and unkind. This character is popular.Therefore, we jump to a quick conclusion (结论) that popular people aremean and unkind.Things such as improper behaviors and rumor-spreading are terrible and should always be seenin a very serious light. However, it is important to recognize that these are not the behaviors of popularpeople, but bullies.So, in summary, do not be afraid to be popular and have many friends. If you are kind to everyoneand treat others with respect, there will be few who can criticize you, for being widely liked is not acurse but a blessing. Just remember that being popular does give you a degree of power, and with greatpower comes a large electricity bill!1．The writer mentions the definition of popularity in paragraph 2 to＿＿．A．bring up his opinion B．give an exampleC．come to a conclusion D．offer his suggestion2．What can we learn from the passage?A．Being popular might offer a shortcut to a life of wealth.B．Students who feel supported have a better chance to achieve more.C．Popular students are usually famous but mean and unkind.D．The less well-liked people consider being popular as something bad.3．Paragraph 4 and 5 are. mainly about＿＿A．the importance of being admired by peersB．the ways to clear up some misunderstandingC．the advantages and disadvantages of being popularD．the reasons why people show hatred to being popular4．The writer probably agrees that＿＿·A．cheerleader types will surely end up as nobodyB．being popular is unnecessary for most studentsC．treating others with kindness is beneficial to popular peopleD．famous people are likely to make mistakes and be criticizedB14、Nowadays，more and more apps have come into the world.

There, husbands and children are not allowed. Why would a woman want to take a vacation without her family? Some women say they need time to be alone.At Mother’s Camp a woman has room for herself. She can sleep, read or watch TV, and no one will bother her. No children will ask, ＂Mom, what’s for dinner?＂No husband will say, ＂Oh, dear, I can’t find any clean socks.＂In fact almost 50% of women in the United States work outside the home. Many of them work full-time and then come home for a second job — taking care of their homes and families. These working women say one of their biggest problems is housework.In the United States, working wives do about 75% of the housework. Many of their husbands say they want to help. But then they burn the rice or they can’t find the pans. They ask so many questions that their wives decide it is easier to do the job themselves.Some women go to Mother’s Camp just to get a break from housework. For two days they don’t cook, they don’t clean and they don’t look after their children and husbands. What do they do? They enjoy warm, sunny weather, walking, swimming or boating in a clear blue lake and sing songs around the campfire. They relax away from home. They have a really wonderful vacation at Mother’s Camp.1．From this passage we can see _________ in the United States.A．women want to work outside the homeB．working wives do most of the houseworkC．husbands do as much housework as their wivesD．women do not like to stay at home with their families2．At Mother’s Camp, women can’t _________.A．watch TV B．read newspapersC．swim in the lake D．bring their husbands and children3．Why would some mothers like to be alone?
