Here are two letters to George and his replies.

Dear George, I’m fourteen and I’m much shorter for my age. What’s worse, I’m very fat. I want to be 55 kg and to be taller and then I can go to the school basketball team and enjoy myself. Can you help me? Bob

Dear George, I’m learning French but I don’t get good marks. I don’t know why. Sometimes I want to give up, but I know I shouldn’t because languages are going to be very important. What should I do? Alice

Dear Bob, Don’t worry if you’re shorter than your friends. Teenagers grow at different times. It doesn’t matter how heavy you are. You are still the same person. Plan your meals with your mum, and she can help you lose weight. Also, try taking more exercise. George

Dear Alice, You’re right. You should never give up, and I’m sure that you’ve made more progress than you think. You can talk to your teacher and ask her what you should do to get a better grade. Talk to your friends who are good at French. Find something that helps you. George

The panda is one of the animals most in danger. There are about 1,000 pandas living in nature reserves today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live and more baby pandas are born in the zoos.
Pandas live in the forests and mountains of Southwest China. They mainly live on bamboo, and each panda needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don’t have many babies, and baby pandas often die. The situation is becoming very serious.
Our government is working hard to save pandas. There are more than 30 nature reserves to protect pandas but these are not enough. The government has made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food to eat and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.
Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol for the World Wide Fund for Nature. The WWF works to protect all animals in danger, so the panda has become the symbol of all animals in danger. There is still a long way to go to save the panda. Think of other animals in danger such as tigers ,whales, turtles and elephant—we need to save the panda, and we need to save them, too.
【小題1】Paragraph 2 is mainly about________.

A．why pandas are in danger

B．why baby pandas often die

C．how to protect all animals

D．how to plant more bamboo

【小題2】The government is trying ________to help the pandas.

A．to build more zoos

B．to send more scientists

C．to make bigger nature reserves

【小題3】________is the symbol for the World Wide Fund for Nature.

When you see the girl for the first time, you may think she is a boy. She is very outgoing（外向）. Who is she? Wang Meng, the Chinese top skater.
On the evening of February 26th, 2010, Wang Meng first got to the finishing line in 1 minute and 29.213 seconds in the women’s 1000 meters short track speed skating final（短道速滑決賽）at the Vancouer Olympic Winter Games（溫哥華冬奧會(huì)）. After she succeeded in the 500-meter and 3000-meter races, she won her third gold medal this time. With this one China won four gold medals in the women’s short track speed skating. That helped China first win the team gold medal in Winter Olympics history.
Just before the final race Wang Meng caught a bad cold and coughed terribly. With the words of “You can, you can do!” she won at last. She said, “I really feel these three gold medals belong to my team, to China. It was with the help of my team that I won the prize.”
Though Wang Meng is only twenty-four, she has been the most successful Chinese skater. Chinese are proud of her and her team. We hope she will be faster in Sochi Olympics in 2014.

Sixteen years ago a boy gave me an important gift. 【小題1】_________
It was the early autumn of my first year at a middle school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

假定你是李華，最近你們班就“低碳”生活方式進(jìn)行了討論，你的美國(guó)朋友Jack來(lái)信向你詢問(wèn)討論情況，請(qǐng)你用英語(yǔ)寫封回信，簡(jiǎn)單參照作文地帶介紹的以下討論結(jié)果：
1.節(jié)水節(jié)電；2.垃圾分類；3.少用紙巾，重拾手帕；4.步行，騎自行車或乘坐公交車。
參考詞匯：低碳low carbon 紙巾tissue 手帕handkerchief
注意：詞數(shù)80-120(不含開(kāi)頭和結(jié)尾所給出的字?jǐn)?shù))；可適當(dāng)增加細(xì)節(jié)了，以使行文連貫；開(kāi)頭已為你寫好，不計(jì)入總詞數(shù)。

（6分）據(jù)圖回答下列問(wèn)題：

（1）據(jù)圖1，若某植物幼苗已表現(xiàn)出向光性，且測(cè)得其向光面的生長(zhǎng)素濃度為m，則背光面生長(zhǎng)素濃度范圍是             。
（2）據(jù)圖1可知，除草劑滅草的原理是使雜草的生長(zhǎng)素濃度大于       （填圖1中字母）。
（3）在探究生長(zhǎng)素促進(jìn)插條生根的最適濃度時(shí)，一名技術(shù)人員用幾種不同濃度生長(zhǎng)素溶液處理插條基部，然后在沙床中培養(yǎng)，觀察生根情況。圖2為生長(zhǎng)素促進(jìn)枝條生根的情況。請(qǐng)結(jié)合圖1判斷，在下列各項(xiàng)濃度值中，最好選用（   ）

A．3mg·mL-1

B．6 mg·mL-1

C．9 mg·mL-1

D．4.5 mg·mL-1

（4）生長(zhǎng)素的主要作用是促進(jìn)細(xì)胞縱向伸長(zhǎng)，其作用機(jī)理如圖3所示，請(qǐng)回答下列問(wèn)題：

①生長(zhǎng)素作用的第一步是與細(xì)胞膜上的受體結(jié)合，形成“激素—受體復(fù)合物”，這一過(guò)程體現(xiàn)了細(xì)胞膜的              功能。
②實(shí)驗(yàn)發(fā)現(xiàn)，細(xì)胞在持續(xù)生長(zhǎng)過(guò)程中，細(xì)胞壁將發(fā)生一定變化，出現(xiàn)這種現(xiàn)象的原因是由于              （填細(xì)胞器）為細(xì)胞壁添加了新的成分。
③此外，Ca²⁺ 還能激活細(xì)胞中的轉(zhuǎn)錄因子，它進(jìn)入細(xì)胞核后，能引起         酶催化mRNA的合成。

（10分）某生物興趣小組為研究某植物生長(zhǎng)發(fā)育過(guò)程中植物激素間的共同作用，進(jìn)行了相關(guān)實(shí)驗(yàn)。
（1）下圖為去掉其頂芽前后，側(cè)芽部位生長(zhǎng)素和細(xì)胞分裂素的濃度變化及側(cè)芽長(zhǎng)度變化坐標(biāo)曲線圖，據(jù)圖分析：

①激素甲代表的是              。
②高濃度的生長(zhǎng)素和細(xì)胞分裂素對(duì)側(cè)芽萌動(dòng)分別起的作用是         。
（2）為研究根的向地生長(zhǎng)與生長(zhǎng)素和乙烯的關(guān)系，該興趣小組又做了這樣的實(shí)驗(yàn)：將該植物的根尖放在含不同濃度的生長(zhǎng)素的培養(yǎng)液中，并加入少量蔗糖做能源。發(fā)現(xiàn)在這些培養(yǎng)液中出現(xiàn)了乙烯，且生長(zhǎng)素濃度越高，乙烯的濃度也越高，根尖生長(zhǎng)所受的抑制也越強(qiáng)。
①該實(shí)驗(yàn)的因變量是          。
②為使實(shí)驗(yàn)嚴(yán)謹(jǐn)，還需要另設(shè)對(duì)照組，對(duì)照組的處理是          。
③據(jù)此實(shí)驗(yàn)結(jié)果可推知水平放置的植物根向重力生長(zhǎng)的原因是：高濃度的生長(zhǎng)素誘導(dǎo)產(chǎn)生了乙烯，從而          。
