Doctors try to give blood to a person according to the person’s blood type. Blood type O can be given to a person with any other blood type, but doctors also need to make sure that the “RH factor (因子)” in patients’ blood matches the blood they are given. If people have one kind of protein (蛋白质)in their blood, they are RH positive (Rh+). If people do not have the protein, they are Rh negative (Rh-). Most people are Rh+.
If a mother has an Rh- blood type, she may have trouble when she has a baby. If her baby is Rh+, the baby’s blood may mix with the mother’s blood before the baby is born. The mother’s blood will change. If the mother has another Rh+ baby, the mother’s blood will attack the baby’s blood. The baby may die or become sick. Doctors have to watch the mother and baby carefully in these cases.
小题1:Who named the blood type?
A.Albert Einstein. | B.Thomas Edison. |
C.Albert Schweitzer. | D.Karl Landsteiner. |
A. Blood type A. B. Blood type B.
C. Blood type AB. D. Blood type O .
小题3:What must be in a person’s blood if the person is Rh+?
A.Special water. | B.A special protein. | C.Baby’s blood. | D.Electricity. |
A.Mother (Rh+) / baby (Rh+). | B.Mother (Rh+) / baby (Rh-). |

Peter watches a lot of films and reads a lot of books about animals. Each bird knows which way is south. Bats (蝙蝠) can fly at night and find their way with their ears. He feels embarrassed (困窘的) because all these animals have a good sense of direction. He tries to find his way with the help of stars in the sky. There is a star called the North Star, and he knows how to find it.

Here is some advice for you:
Film night: choose an English film with Chinese subtitles字幕. You can stop the film at any time and help your family learn new words and expressions according to subtitles on the screen.
Sports night: you can invite your family members to go skating or swimming. You can teach a few words when you play sports together. For example, “you fell down” or “your skates look cool”.
Novel night: choose a classical English story that your family members may know. You can read it to your family members and tell them about the novel in English
Make an English family tree together: you can teach your family members what each person is called in English, such as “father” and “cousin”. It is a good way to make your family members interested in English.

I teach a course called History Matters in college. My goals for the class include a deep discussion of historical subjects and ideas. Because I want students to fully study the material and discuss with each other in the classroom, I have a rule – no computers, iPads, phones, etc. When students were told my rule, some of them were not happy.
Most students think my reasons for this rule include negative experiences in the past when students made wrong use of technology. There’s a bit of truth to that. I’ve seldom had students make wrong use of technology in my classes; however, I have been e-mailed by students while they were in other teachers’ classrooms.
Some students think that I am anti-technology. There’s no truth in that at all. As I noted above, I love technology and try to keep up with it.
The real reason why I ask students to leave technology at the door is I think there are very few places in which we can have deep conversations. Interruptions (中断) by technology often break students’ thoughts and make them depend too much on outside information for ideas. I want students to dig deep in themselves for ideas. I want them to push each other to think differently and to make connections between the course material and the class discussion.
I have been teaching my history class in this way for many years and the evaluations (评价) show student satisfaction with the environment that I create. Students realize with deep conversation and difficult tasks, they learn at a deeper level – a level that helps them keep the course material beyond the classroom.
I am not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I will continue my plan. A few hours of technology-free dialogue is just too sweet to give up.
小题1:The writer’s rule for his History Matters class is ____.
A.discussing historical ideas deeply |
B.studying and discussing the materials |
C.leaving technology out of the classroom |
D.making right use of technology in class |
A.similar | B.unforgettable | C.special | D.unpleasant |
A.Students make right use of technology in other teachers’ classes. |
B.The classroom is one of the good places to have deep conversations. |
C.The writer encourages students to agree with others after discussion. |
D.Students are unhappy with the writer’s way of teaching history. |
A.technology has different influences in different classes in college |
B.technology makes it difficult to have true communication in class |
C.history classes can help students to develop their deep thinking |
D.it is time for him to give up his teaching method in history class |

Solar energy can be used to heat homes, buildings, water, a 小题6:__ make electricity. Today, more than 200,000 houses in the United States make use of the s 小题7:energy.
Cars are an important part of life for most people. But cars also cause pollution and give out a lot of greenhouse gases into the air. L 小题8:, there are some cars that are better for the environment. These cars can travel longer on a smaller amount of gasoline. They don"t p小题9: much, either. Using these kinds of cars can help reduce the amount of greenhouse gases in the air.
Many things, l 小题10: computers, TVs, stereos, and VCRs, have special labels on them. The label says "Energy" and has a picture of a star. Products with the ENERGY STAR® label are made to save energy. Buying products with ENERGY STAR® labels will help protect the environment.
There is another way to help your friends or other people to find you. Give them a signal(信号)outing or whistling (吹口哨) three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.
Keep on shouting or whistling, always three times together. When people hear you, they will give two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a small room with branches.(树枝)
What should you do if you get hungry or need drinking water? You would have to leave your little branch room to look for something to eat and drink. Don’t just walk far away. Pick up small branches and drop them as you walk so that you can find your way back.
The most important thing you need to do when you are lost ---stay in one place.
小题1:When you hear two shouts or whistles, what does that mean?

B.Someone is calling for help. |
C.People will come to help you |
D.Someone is lost. |
