Speaking
What do you know about the animals in the photos ?
blue whale
panda
African elephants
blue whale: I know that they're being hunted and their number is getting dramatically smaller, so they're in danger of extinction. Blue whales need large and clear water habitats, so it's difficult for them to adapt to the changes.
panda: I know that panda is the treasure of China. Now the number is about 2,000 and China has built some national natural preserves such as the Wo Long National Natural Preserve in Si Chuan to provide enough bamboo for them.
Arican elephants: Because of their ivory, African elephants are being hunting illegally. So the number of them is dramatically decreasing. Luckily, many countries have passed laws to ban on trading the ivory and protect elephants.

Pronunciation---stressed syllables
音节是英语当中最小的单位。每个音节含有一个音节核，通常由元音音素构成，辅音是音节的分界线。所以，音节就分成单音节、双音节和多音节。


A.单音节词
1.两辅音之间不管有多少个元音，一般都是一个音节。如：bed，seat， beau'ty。
2.两元音字母之间有一个辅音字母时，辅音字母归后一音节，如：stu'dent，la'bour。
3.有两个辅音字母时，一个辅音字母归前一音节，一个归后一音节，如：let'ter，win'ter

4.不能拆分的字母组合按字母组合划分音节。如：fa'ther，tea'cher。
Pronunciation---stressed syllables
B. 双音节词
1.有 a-, be-, de-, re-, res-, in-, im-, en-, em-, es-, ex-, con-, com-, dis-, mis-, pre-, per-, pro-, trans- 等前缀的词，第二个音节是重音。如： be'lieve, de'cide
2.有 de-, in-, re-, con-, pre- 等前缀的重音与词义和词类有关, 一般名词的重音在第一个音节上，其它的词性在第二个音节上。如：'present pre'sent

一般在第一个音节重读。如：sorry, movie, cover
