C
【解析】:“當(dāng)聽(tīng)到那熟悉聲音的時(shí)候,他正在吃飯”。 考查連詞區(qū)別,尤其是when和while區(qū)別1. When 可以做關(guān)系復(fù)句中的引導(dǎo)詞,指代前面的成分,如“It was in 1997 , when Hong Kong was returned.” “I like the day when there are not many student in campus.” *2. While 可以表示“然而”的意思,做轉(zhuǎn)折連詞3. When 和while 都可以表示“當(dāng)……時(shí)候”,但while 更側(cè)重于表示在……期間內(nèi),在……過(guò)程中,可以對(duì)比一下兩個(gè)句子: “when I saw him ,I called him back.” 和“while my mother is cooking ,I am reading in yard"
【高考考點(diǎn)】:狀語(yǔ)從句連詞辨析
【易錯(cuò)點(diǎn)】:誤選while
【備考提示】:while和when不同用法是每年高考熱點(diǎn)之一。

When we donate blood, a small amount is usually taken in advance for at least ABO and Ph systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.
The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物質(zhì)) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The rarest is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world…
84 donors are Rh+ | 16 donors are Rh- |
38 are O+ | 7 are O- |
34 are A+ | 6 are A- |
9 are B+ | 2 are B- |
3 are AB+ | 1 is AB- |
