Not long ago, no one understood that infectious diseases were caused by tiny organisms that moved from person to person. Even now, although we know that tiny living microbes cause disease, how they do so is not always obvious. 1. They can also be transmitted through our skin through insect or animal bites. The best way to prevent infections is to block pathogens （病菌）from entering the body.
The first line of defense is to keep germs at bay by following good personal health habits. Wash your hands well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks. 2. Wet your hands thoroughly. Lather（泡沫）up with soap or cleanser, and rub it into the palms and backs of your hands and your wrists. Be sure to clean your fingertips, under your nails and between your fingers. Wash under running water. 3.
Whether you are young or young at heart, getting vaccinated（接种疫苗）is an essential part of staying healthy. 4. such as a temporarily sore arm or low fever, they are generally safe and effective. Vaccinations are essential if you are to avoid getting sick. In general, children should receive the recommended childhood vaccinations. Adults should make sure their vaccinations are up to date. When traveling abroad, check with your health care provider about additional immunizations（免疫）.
5. Stay clear of wild animals. Many wild animals, including bats, foxes and coyotes, can spread the virus to humans by biting. Keep your pets away from wild animals, too. Dogs, cats or any other type of warm-blooded animal can pick up the virus and pass the virus along to people.
A.Dry your hands and wrists thoroughly.
B.Use animal control to prevent infections.
C.While vaccines may cause some common side effects,
D.Although vaccines can not prevent some rare diseases,
E.Other wild animals can not transmit the virus and other infections.
F.We do know that most microbes enter through openings in the body.
G.You should also wash up after blowing your nose, coughing, or sneezing.

I was in the Sants Cruz Mountains not long ago, speaking and singing at a women’s conference. We were focusing on the theme of loving others in practical ways through our gifts, and something in particular happened during one of the sessions（会议）will remain imprinted in memory.
A young Syrian woman (Lilith) was invited to the conference at the last minute, and everyone seemed surprised and delighted that she’d actually come. Just a few days earlier, Lilith had fled her country and found refuge with one of the women attending the conference. As an Orthodox Christian in Syria, she and her loved ones had become attacked targets of violent terrorist groups in the country’s ongoing civil war.
Lilith had witnessed horrors no one of her young age should ever see. Despite the further danger it presented, she’d decided to leave her home and her family to find safety here in America. Knowing some of her story, and seeing her sitting through the sessions at the retreat（畏缩不前）---head, covered in a scarf, bowed toward the floor---broke my heart.
Lilith’s story touched all of us, including Pam, who was quilt maker. Pam had just finished a beautiful quilt, and had brought it with her. She, along with a few of the leaders, decided to give it to Lilith as a symbol of their comfort and love.
During our last session, Lilith was called forward and prayed over, hugged, and wrapped up in that beautiful quilt. I thought of the many hours Pam undoubtedly spent working on it, and the terrible events that led Lilith to this moment---surrounded by the beauty and love quilt embodied. I wept. When they told her it was for her, she wept.
1.What is the purpose of the women’s conference?
A. To help others in a practical way. B. To win equal rights for women.
C. To get together to dance and sing. D. To exchange gifts with each other.
2.Why did Lilith go to America?
A. To attend the women’s conference. B. To find safety.
C. To find her family. D. To find a better job.
3.From this passage, we know that the writer is____________.
A. enthusiastic B. sympathetic
C. intelligent D. talented
4.What is the meaning of the underlined word?
A. a place of interest B. a place of danger
C. a place of conference D. a place of shelter

One day not too long ago the employees of a large company in St .Louis, Missouri returned from their lunch break and were greeted with a sign on the front door. The sign said: “Yesterday the person who has been hindering(阻碍) your growth in this company passed away. We invite you to attend the funeral in the room that has been prepared in the gym.”
At first everyone was sorry to hear that one of their colleagues had died, but after a while they started getting curious about who this person might be. The excitement grew as the employees arrived at the gym to pay their last respects. Everyone wondered: “Who is this person that was hindering my progress?

Not long ago, few little girls imagined they could grow up to be astronauts. In 1983, that changed. Sally Ride made history by becoming the first American woman to travel into space.
Ride died at the age of 61. “Sally was a national hero and a powerful role model,” President Barack Obama said in a statement.
Ride became interested in space when she was a kid. “If you asked me when I was 12 whether I wanted to be an astronaut, I’m sure I would have said yes,” she told TFK in a 2010 interview. “But I didn’t even think about that as a possible career.”
After studying physics in college and graduate school, Ride got her chance. She was accepted into NASA’s astronaut training program in 1978, and then chosen to be the first American female in space. In 1983, she blasted into space aboard the Challenger shuttle. “There is no amusement park ride on Earth that even comes close. It can’t be more wonderful,” she said.
Ride returned to space on the Challenger a second time in 1984. In the two missions, she spent a total of 343 hours in orbit. After that, she remained involved with the space program and also worked to share her passion for space with kids. She wrote five science books about space for children, and started her own science education company.
Ride knew that she held a unique place in history. “I realized how important it was for a woman to break that barrier and open the door for other women to be able to do the same exciting things that men had been doing,” she said.
Since Ride’s historic trip, more than 40 other American women have traveled to space. They all had Ride to thank for opening the door to the final frontier.
1.Which of the following is true?
A. Sally was the first person to travel to space in America.
B. Sally wanted to be an astronaut even when she was a pupil.
C. Sally was interested in space, so she chose astronautics as her major.
D. Sally graduated from college and first traveled to space in 1983.
2.From the fifth paragraph, we know that Sally .
A. was good at doing business
B. wanted to be rich by doing business
C. became a famous writer at last
D. had a lasting interest in space
3.What can we infer from the text?
A. Sally inspired many American women to travel to space.
B. Sally made great contributions to American economic development.
C. Women astronauts used to be looked down upon in American history.
D. The government did not allow women to become astronauts in the past.
4.Which of the following could be the best title for the text?
A. Sally Ride’s first space trip
B. A national hero flying in space
C. Sally Ride, a successful businesswoman
D. Sally Ride, a real educator for kids

Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old. But doctors in the United States now say babies begin learning on their first day of life.
A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people.
The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers.
Experts say the first three years of a child’s life are the most intensive period of language and speech development. This is the time when the brain is developing. Language and communication skills are believed to develop best in an environment that is rich with sounds and sights. Experts say babies should repeatedly hear the speech and language of other people.
America’s National Institutes of Health says evidence suggests there are important periods of speech and language development in children. The ability to learn a language will be more difficult if these periods pass without early contact with a language.
The first signs of communication happen during the first few days of life, when a baby learns that crying will bring food and attention. Research shows that most children recognize the general sounds of their native language by six months of age. By that time, a baby usually begins to make sounds. These sounds become a kind of nonsense speech over time.
1.When does the author think babies begin to learn? (no more than 9 words, 2 marks)
________
2.Why do babies smile to please her mother or other caregiver? (no more than 9 words, 2 marks)
________
3.According to experts, how can babies’ language and communication skills develop? (no more than 8 words, 3 marks)
________
4.What does the author mainly tell us? (no more than 8 words, 3 marks)
________
