We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.

Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.

During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.

Scientists often use mice for research because they have a similar genetic（基因） structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.

Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.

1.The study conducted by researchers aimed at learning about________

A. the advantages and disadvantages of sugar

B. the negative effects of sugar on people’s health

C. the genetic structure of mice

D. American’s diet

2.According to the study, which of the following statements is wrong?

A. Sugar can even shorten lives.

B. Sugar’s negative effects are not noticeable.

C. Mice are more likely to diet when fed a diet containing 25% more sugar.

D. Eating much more sugar can make mice put on weight and get high blood pressure.

3.From the passage we can infer_______

A. sugar plays a very important role in Americans’ diet

B. kids consume more sugar than adults in America

C. the study on human beings lasted 58 weeks

D. the genetic structure of mice is totally different from that of people

4.What’s the best title of the passage?

A. Living a sweet life

B. Kids consume much more sugar

C. Genetic structure of humans

D. Danger of sugar

Many people spend more than four hours per day on WeChat, and it is redefining the word “friend.” Does friending someone on social media make him or her your friend in real life?

Robin Dunbar, a professor at Oxford University, found that only 15, of the 150 Facebook friends the average user has, could be counted as actual friends and only five as close friends. WeChat may show a similar pattern.

Those, with whom you attended a course together, applied for the same part-time job, went to a party and intended to cooperate but failed, take up most of your WeChat friends. In chat records, the only message may be a system notice, “You have accepted somebody’s friend request”. Sometimes when seeing some photos shared on “Moments”, you even need several minutes to think about when you became friends. Also, you may be disturbed by mass messages sent from your unfamiliar “friends”, including requests for voting for their children or friends, links from Pinduoduo.com (a Chinese e-commerce platform that allows users to buy items at lower prices if they purchase in groups) and cookie-cutter blessings in holidays.

You would have thought about deleting this type of “friends” and sort out your connections. But actually you did not do that as you were taught that social networking is valuable to one’s success. Besides, it would be really awkward if they found that you have unfriended them already. Then, you keep increasing your “friends” in social media and click “like” on some pictures that you are not really interested. But the fact is that deep emotional connections do not come with the increasing number of your friends in social media.

If the number of your friends reaches 150, maintaining these relationships can be tough to you, and sometimes even will make you anxious. According to Robin Dunbar, 150 is the limit of the number of people with whom one can maintain stable social relationships.

1.What can we learn from Robin Dunbar’s finding in Paragraph 2?

A.A Facebook user has 250 friends on average.

B.Most of the social media friends can be actual friends.

C.Among our social media friends, only a few people matter.

D.Only 15 people of a person’s Facebook friends can be close friends.

2.What does the third paragraph tell us about most of your WeChat friends?

A.You have deep communication with them.

B.You benefit a lot from their mass messages.

C.You just have a nodding acquaintance with them.

D.You become friends with them in important occasions.

3.What can we infer from the last paragraph?

A.We will be anxious if we make friends online.

B.We should avoid making any friends in social media.

C.We should make as many friends as possible in social media.

D.We have difficulty managing relationships with over 150 people.

There is a lot of talk these days about how kids should be interested in science. Here’s an area of science for everyone, and these cool new books might inspire you to discover your inner scientist.

Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12

Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur’s coloring was, but now artists have to use their imagination to determine how these huge creatures looked.

Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13

This book takes readers back to the beginnings of space exploration—thousands of years ago, when people began star observation—and forward to today’s search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein’s universe using a T-shirt. The activities are perfect for cold winter days.

Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich, 272 pages, ages 7 and older
