2 . Food has always been one of the greatest wants of humankind. The search for food is the_______human behavior. Thus，_______food were easier to get and prepare，it would be really helpful for humankind. It would reduce a great burden (负担). The development of processed foods (加工食品) has made food easier to get and prepare. _______every coin has two sides. Apart from its advantages，the_______of cooking also has its disadvantages.

Though processed foods seem like a great way to save_______，they offer much less nutritional (营养的) value than traditional foods. People today are so busy that they are not able to spend enough time preparing their food. As a result，many people_______to eat processed foods，ready­to­cook meals and various fast foods. But what will_______if one eats such food all year round? It will damage your health. The nutritional value of the food is not so high. Worse still，research shows that preservatives (防腐剂) used in these foods are_______to children. That's why health experts warn people not to eat too much of such_______food.

Besides，since people spend little time preparing food，the culture of cooking is slowly ________. Cooking is not done just to satisfy hunger；it is also a(n)________form of art. Across the world，there are thousands of ________cooking styles. If young people are used to processed foods，few of them will develop great cooking________. And when they become parents，it will be hard for their children to enjoy a(n)________home­cooked meal. What's more，cooking is a great time for families to connect. There is a lot of________when family members are preparing food together.

In a word，I believe though processed food has made the preparation of food much easier，it has not been a good step for humankind.

Kitchen technology has reached new heights. So far, astronauts on the International Space Station     1    (make)the universe’s first space-baked cookies. They are     2     very first kind of food to be baked in space from raw ingredients. The astronauts said     3    (eat) freshly baked food will make them happy while on the space station. It will be a comforting     4    (remind) of home. This will be important for astronauts going to the moon or on the long journey to Mars.

Baking the space cookies once     5    (think) extremely difficult. On Earth, cookies take about 20 minutes     6    (bake) in an oven heated to 150 degrees Celsius(302 degrees Fahrenheit). That was not long enough in space. The first cookie came out     7    (total) undercooked.

The space bakers turned     8    the oven’s temperature and baked the dough for     9    (long)until they were successful. The fifth cookie they made took 130 minutes to bake. The space-baked cookies are now in a laboratory in Houston, Texas. Scientists will test them to see     10     they are safe to eat.

4 . Craziest Food Festivals sounds like a joke topic, but once you start looking into it, you’ll realize they’re everywhere — the crazier, the better.

1. Bibimbap Festival

In the South Korean town of Jeonjuloves, their “mixed rice” dish is a hearty serve of rice topped with raw beef, a rainbow of vegetables, a raw egg and gochujang sauce so much. They take four days out of October to celebrate it.

Like any festival there’s music, entertainment and magic, but making it that little bit different is the bibimbap that’s whipped (搅拌) up in a big bowl by dozens of chefs and served to over 400 people.

2. Waikiki Spam Jam

Who knew this canned meat had so much love? Well, it turns out that a can of Spam is the go-to item in Hawaii, along with a grass skirt and garland (花环). The people of Hawaii love Spam so much that they even spend a day in May giving out the best Spam, a type of cheap canned meat made mainly from pork.

3. Bessieres Easter Egg Festival

At Easter time, for those in the French town of Bessieres it’s all about an egg far less sweet.

Here they celebrate the holiday by getting dozens of chefs to make one large omelette (煎蛋卷) — 15,000 eggs strong — for the townsfolk (市民).

4. Potato Days Festival

This festival actually takes place in Barnesville, Minnesota, the US. Over the last Friday and Saturday in August the town celebrates its potato-growing skills by hosting potato picking and peeling contests, as well as a Miss Tater Tot pageant (盛典) for five- and six-year-old girls.

5 . Cooking programs and classes for children seem to positively influence children's food preferences and behaviors，according to a recent review. And，although the review didn't look at long-term effects of such programs，the findings suggest that such programs might help children develop long-lasting healthy habits.

This research comes at a time when childhood obesity( 肥 胖 ) rates have been rising rapidly. More than one-third of adolescents in the United States were obese in 2012 ， according to the U．S.Centers for Disease Control and Prevention (CDC)．This trend has been caused，at least in part，by a significant decrease in the amount of meals that people consume at home since the 1980s， according to background information in the study.

Cooking education programs，such as Food Explorers，teach children about new healthy foods and how to prepare them. They also stress the importance of eating five fruits and vegetables every day. A volunteer parent explains a new food to the group，and the kids make something based on the lesson，such as fruit or vegetable salad. Depending on the program，kids may be sent home with information about healthy foods to bring to their parents，the review explained.

The study team reviewed eight other studies that tested different types of cooking education programs. Children in these classes were between 5 and 12 years old，according to the review. The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime. The study found that it is particularly important to expose kids to healthy foods on a number of occasions. This makes them feel comfortable with the new foods，which helps them build healthy habits.

The study stressed the importance of getting parents involved in(参与) their children's eating habits. Parents who are unable to enroll their kids in a cooking class can achieve similar benefits   by having their kids help them while they prepare meals at home. Children are more comfortable at home，which makes them more receptive to new foods because they will make the connection to a positive experience.
