If you plan to take your pet on a trip，prepare ahead of time. At least two weeks before you leave，take your pet to a vet. See if he or she is tit for travel and ask if he or she should have any medicine before leaving. The vet may suggest certain pills for sickness or for calming the pet.
Some states or foreign countries have health laws that say animals must have certain injections(注射)before they can be allowed to enter. Your vet may have this information. You can also get help on the United States and Canadian laws from a book published by the Department of Agriculture which some libraries have. For information on foreign countries， check with their consulates (领事馆).You can also ask the airlines on which you are travelling.
Find out if the places where you plan to stay allow pets because many do not.
If you are going by plane or train，ask if pets are allowed. If they are，ask where they will be kept and who will care for them. The big bus lines in this country do not allow pets.
Choose your pet’s box carefully. Plastic boxes are better than cardboard or wooden ones because they can' be chewed(嚼碎).
If going by plane or train during warm weather，try to go in the cooler early morning or evening hours. Also try to avoid (避免)very cold winter weather because pets often suffer from cold. Even in your own car， be careful. Do not leave the animal inside with the windows closed because the car may become too hot or too cold.The main idea of this passage is to_________

"I am so busy with my study． I don't even have enough time to have breakfast．"said Zhangli， a middle school student． Do you have the same problem __A__ Zhangli？ However， missing breakfast could raise your risk of heart problem by 87 percent， according to a new study． Researchers at the University of Iowa analyzed 18 years of data on 6，550 people over 40 years old who had no history of heart problems．They were given regular surveys __B__ included the question， "how often do you eat breakfast？ Most （59 percent）ate breakfast every day，but 5.1 percent never did，10.9 percent rarely did， and 25 percent would miss for a few days． The team found that①早餐习惯与心脏病风险之间存在明显关联．Those who didn't eat in the morning were up to 87 percent more likely to develop heart problems．
" It's believed that ②an， important， day， breakfast， the， is， meal， of， but there has been an
increasing prevalence （普遍）of missing breakfast over the past 50 years in the United States， with as many as 23.8 percent of young people missing break fast every day，" the researchers said．"However， studies on the health effects of missing breakfast are rare．"
The team pointed out a few factors which could underlie this connection． ③ Firstly ， those who don't eat breakfast may be more likely to snack unhealthily ．Secondly， breakfast may help to balance blood sugar levels and control blood pressure． The findings were published on the American College of Cardiology． Some days later a similar study showed people who missed breakfast and ate a late dinner were less likely to survive a heart attack． And Borja Ibanez， a doctor of medicine， also pointed out those who didn't eat breakfast were more likely to smoke， be lack of exercise， and drink alcohol．

Many environmental groups are warning that oceans of the world are in great danger． In the past 50 years，the number of water with zero oxygen（氧气） in the open ocean has increased more than four times． In the near coast water bodies， including the river mouth and seas， low﹣oxygen areas have increased more than 10 times since 1950．Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms． To stop the drop，the world needs to control in both climate change and nutrient（养分） pollution．
Oxygen is a must to life in the oceans． The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment．
This is the first time for the scientists to take such a deep look at the causes， results and solutions to low oxygen worldwide， in both the open ocean and the near coast waters．About half of the oxygen on Earth comes from the ocean． However， mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters， where oxygen is too low to support most sea life．
In the areas traditionally called"dead zones"． like those in Chesapeake Bay and the Gulf of Mexico， oxygen drops to levels so low that many animals have trouble in breathing and die．As fishes run away from these zones， their living areas become smaller and smaller． But the problem goes far beyond "dead zones"． Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death． Low oxygen also can cause the release of dangerous chemicals．Although a few animals can grow well in dead zones， overall biodiversity（多样性）falls．

Thanks to the hybrid rice that was discovered by Yuan Longping， the hunger problem of thousands of Chinese people was mostly fixed in the 1980s．
On Sept 8 th，Yuan， together with two other scientists，won China's 2018 Future Science Prize， for his continuous research on rice． Even on his 88th birthday on Sept 7 th，he took part in the International Development Forum of Rice Production in Hunan province． Although he was recovering from an illness at the time， he was happy to talk to reporters about his latest work on seawater rice．
Yuan has been researching on rice since he was at college． In 1964． he discovered a natural hybrid rice plant in Hainan． Since then， he has focused on developing high﹣yield， hybrid rice varieties
（多样性）．In 1973． he became the first to successfully cultivate（培育） a type of hybrid rice species in
the world．With the hard work of Yuan's group for about ten years， the production of the rice was increased．（From 150 kg per mu （亩） to 500 kg per mu and more． ）These varieties now take up about two thirds of China's rice crop， according to China News． So， it's no wonder that he's known as the "Father of Hybrid Rice"．
And because of China's Belt and Road （一带一路）initiative． Yuan's hybrid rice is helping to solve food problems around the world． Indeed， according to Xinhua News Agency， hybrid rice plants in Kenya produce four to five times more rice than the country's usual nice plants．
With a rising fame all over the world， Yuan gave a speech in English at the 9th Shandong High﹣Level Talents Forum in Qingdao last year． His speech made him an internet sensation．Beginning with"I speak broken English"， his 20﹣minute speech turned out to be a huge success，with barely any pauses or mistakes． The humble Yuan was simply being modest during his speech．According to an article in 1999 by CNN， the scientist speaks both English and Russian fluently． "I never need an interpreter when I go overseas，" he told the US news network．
But in spite of his great knowledge， Yuan understands that even the wisest people should still be open to learn new things． "The farmers of our country possess rich experience in planting rice，"he told Xinhua．" We should learn from them．"

Global warming is a big problem that we have to stop． One of the best things we do is to plant more trees． Trees can take in CO2 in the air and stop global warming．（1）
A team of scientists at Boston University has been working with NASA to study Earths green vegetation（植被）． They used a special NASA camera and found that global leaf area had increased by 5 percent since the early 2000s． （2） That's about one﹣quarter of the size of the entire Amazon rainforest．
The growth mainly came from China's forest protection programs， NASA said． For example， since 1962． China has been planting trees in Saihanba． Hebei Province． It was once a desert，（3）
（4） Ant Forest， a feature in Alipay app， gives users points for doing eco﹣friendly things such as walking and going paperless in the office． Users can then use these points to water and grow their own virtual（虚拟的）trees． When the virtual trees are big enough， Ant Forest will plant real trees somewhere in the world．（5）
A． More than 55 million trees have been planted in this way．
B． The Chinese public has also joined in these activities recently．
C． And China was responsible for 25% of that gain． according to the study．
D． However， people there can produce vegetables without any difficulty now．
