A

Obesity (肥胖症) is becoming a problem in our busy society, and almost one in three American adults is now

considered to be obese. Children obesity is alsoat an all-time high.

Obesity means being very overweight. If you are obese, you have too much bodyfat. If you eat more food

than your body can use, this will make you put on weight. Food that your body does not need will be stored as fat

by your body.

The following are the major factors that increase the risk of obesity.

What you eat plays a major role in weight gain. Eating a lot of fast food such as hamburgers, sweet drinks, ice

creams and other sweet food can increase the risk of becoming obese.

If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy

for physical activities.

The chances of you being obese are greater if your parents are obese.

There are many psychological factors that cause people to eat too much. People who are worried, unhappy or

bored will often eat to make themselves feel better. This is known as comfort eating.

Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need

to eat less, and if you do not eat less, you will put on weight. Obesity can cause many health problems such as

heart problems, high blood pressure and many other serious medical conditions.

It’s a big change from homeless teen to Yale (耶鲁)medical school student, butperseverancepaid off for

Chelesa Fearce of Clayton County, Georgia.

Fearce was a fourth grader when her mom was diagnosed (诊断) with Lymphoma (淋巴瘤).That began a hard

time for the family. They had to move in and out of shelters,hotels and even the family car.

“I know I have been made stronger. I was homeless. My family slept on the floor and we were lucky if we got

more than one full meal a day. Getting a shower, food and clean clothes was an everyday struggle,” Fearce said in

a speech she gave at her high school graduation ceremony. Fearce overcame her day-to-day struggles by focusing

on a better day. “I just told myself to keep working, because the future will not be like this anymore. And that

helped me get through,” she told WSBTV.

Fearce was determined to be a good role model for her younger sister. She found inspiration in her late

grandmother, struggling with deadly diseases, who gave Fearce emotional support. In her junior and senior year,

Fearce took both high school and college courses, missing out on the free meals she depended on so she could get

to her college classes. Despite having to use her cellphone to study after the shelter lights were turned off at night,

she not only graduated as valedictorian (毕业生代表) of her 2013 class with a 4.5 grade average, but was also

given a ride scholarship—including a meal plan to Spelman College in Atlanta.

After graduation, she worked full time for two years at the National Institutes for Health

inBethesda,Maryland,doing research on drugs. Last fall, she entered Yale and set a course to earn both a PhD and

medical degree.

4. What does the underlined word “perseverance” in paragraph 1 refer to?

A. instant passion. B. continuous efforts.

C. great patience. D. selfless ambitions.

5. How did Fearce feel facing the sufferings?

A. Sad and disappointed. B. Stressed and defeated.

C. Determined and confident. D. Joyous and contented.

6. What can we know about Fearce’s learning experience?

A. Her grandma encouraged her to study medicine.

B. Her high school offered her free meals and courses.

C. She failed to study late due to frequent power cut.

D. She gained remarkable high school achievement.

7. What can be a suitable title for the text?

A. From Homeless to Yale

B. Meet American’s Top Girl

C. Disabled but not Defeated

D. Chelesa Fearce: A Girl of Many Talents

C

California's August Complex Fire tore through more than 1,600 square miles of forest last summer,burning

nearly every tree in its path. It was the largest wildfire in the state's recorded history, breaking the record

previously set in 2018. After the fire, land managers must determine where to most efficiently plant new trees.

A predictive mapping model called the Postfire Spatial Conifer Restoration Planning Tool recently described in

Ecological Applications could inform these decisions, saving time and expense. The tool can “show where young

trees are needed most, where the forest isn't going to come back on its own, where we need to intervene（干预）

if we want to maintain forests," says lead author Joseph Stewart, an ecologist at the University of California,

Davis.

To develop the model, Stewart and his colleagues classified data collected from more than 1,200 study plots

in 19 areas that burned between 2004 and 2012. They combined these data with information on rainfall,

geography, climate, forest composition and bum so included how many seeds sample conifer trees

（针叶树）produced in 216locations over 18 years, assessing whether the trees release different numbers of

seeds after a fire.

The tool's potential benefits are significant, says Kimberley Davis, a conservation scientist at

theUniversityofMontana, who was not involved in the study. Those managers will still have to make hard decisions,

such as which species to plant in areas that may experience warmer and drier conditions resulting from climate

change, but the model provides some research-based guidance to help the forests recover.

8. What challenge do land managers face after the wildfire?

A. Lack of wood supplies. B. Where to plant new trees best.

C. How to save the burned trees. D. Loss of trees and wild animals.

9. What's the main idea of paragraph 2?

A. The function of the tool.

B. The disadvantages of the tool.

C. The improvement of the tool.

D. The development of the tool.

10. What does the underlined word "They" refer to?

A. The study plots. B. The data.

C. Stewart and his colleagues. D. The seeds.

11. What isDavis' attitude towards the tool?

A. Skeptical. B. Ambiguous.

C. Tolerant. D. Optimistic.

D

Happiness is not a warm phone, according to anew study exploring the link between young life satisfaction

and screen time. The study was led by professor of psychology Jean M. Twenge at San Diego State University

(SDSU).

To research this link, Twenge, along with colleagues Gabrielle Martin at SDSU and W. Keith Campbell at the

University of Georgia, dealt with data from the Monitoring the Future (MtF) study, a nationally representative

survey of more than a million U. S. 8th-, 10th-, and 12th-graders. The survey asked students questions about how

often they spent time on their Phones, tablets and computers, as well as questions about their face-to-face social

interactions and their overall happiness.

On average found that teens who spent more time in front of screen devices — playing computer games,

using social media, texting and video chatting — were less happy than those who invested more time in

non-screen activities like sports, reading newspapers and magazines, and face-to-face social interactions.

"The key to digital media use and happiness is limited use," Twenge said. "Aim to spend no more than two

hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and

exercising — two activities reliably linked to greater happiness."

Looking at historical trends from the same age groups since the 1990s, it's easy to find that the increase of

screen devices over time happened at the same time as a general drop-off in reported happiness inU. .

Specifically, young peopled life satisfaction and happiness declined sharply after 2012. That's the year when the

percentage of Americans who owned a smartphone rose above 50 percent. By far the largest change in teens' lives

between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following

decline in in-person social activities and sleep.

12. Which method did Twenge's team use for the study?

A. Calculating students' happiness.

B. Asking students certain questions.

C. Analyzing data from a survey.

D. Doing experiments on screen time.

13. How does the author develop the finding of the study in paragraph 3?

A. By making a comparison.

B. By giving an example.

C. By making an argument.

D. By introducing a concept.

14. What is the purpose of the last paragraph?

A. To draw a conclusion from the study.

B. To offer some advice to the readers.

C. To prove social activities' importance.

D. To support the researchers' finding.

15. Which of the following can be the best title for the text?

A. Quitting Phones Equals Happiness

B. Screen Time Should Be Banned

C. Teens' Lives Have Changed Sharply

D. Screen-addicted Teens Are Unhappier
