19.Understanding the basic tips on growing grass will help you create a healthy and green lawn.If you plan the right variety at the right time and in the right place,you'll achieve success.
Autumn is the ideal growing season for the majority of grass varieties.Prepare the soil in this season as you do for any other plant.Based on the type of grass that you have chosen,the nutrient requirements may differ.For poor soil that is lack of essential plant nutrients,you can supply it with some organic fertilizer.
To grow grass successfully,make sure you select the correct variety that will adapt to the soil conditions of your area and to the growing location.You can choose the American shade grass variety or native grass varieties.
The sowing of grass can be done on bare soil or on an existing lawn.After sowing the grass seeds,cover them with a layer of top soil to quicken the germination (萌芽) process.In the first few weeks,you should irrigate the area every other day.Reduce the watering frequency after the grass has germinated.The addition of proper fertilizers at the right time is necessary for the healthy growth of grass.In the case of grass growing in shady environments,limit the use of fertilizers.
Weed control is another important tip for growing grass.The presence of weeds in grass growing areas leads to competition for water and nutrients,thus resulting in the poor growth of the planted grass.Hence,in order to avoid this condition,ensure that you remove the weeds regularly.
Lastly,one should also watch out for the presence of diseases and pests around the grass growing site in order to preserve the beauty of the lawn.

5.The public were shocked in March when the news that improperly stored vaccines (疫苗) worth millions of dollars were sold to patients all over the country.
China is trying to rebuild public confidence in vaccines after the news struck fear into the hearts of parents.
Chief government officials should be dismissed if serious vaccine violations (違規(guī)) took place in their jurisdictions (管轄區(qū)),according to a revised regulation (規(guī)定) approved by the State Council.The regulation was passed on Saturday and took effect immediately,the report said.It strengthens management rules for vaccines,including their transportation and storage,and increases punishments for violators.
The regulation requires B-class (non-compulsory) vaccines to be given out like A-class.It also requires disease control departments,hospitals and clinics to keep records of purchases and received inventory (存貨清單).China will establish a system to track vaccines,according to the regulation.Companies and user agencies must record use,so all vaccines can be tracked across their life cycle.
China will also raise the amount of compensation paid to those suffering abnormalities (反常) after receiving vaccines.Measures under consideration include the introduction of commercial insurance to improve fairness and efficiency in compensation.Commercial insurance is expected to play an important role in compensating people for any health problems connected with vaccines.In the past,responsibility for compensation belonged to vaccine producers or to the government.
Meanwhile,local authorities are trying to reduce public worries.At Zhcheng hospital,health workers were spreading vaccine information to parents on Monday.In Northeast China's Jilin province,authorities are pioneering a digital system that makes vaccines storage transparent to the public.In Hefei,capital of Eastern Anhui province,authorities have developed a smart phone application that shares vaccine information.
Immunization (免疫) is the most economic,effective and safest way of preventing,controlling and getting rid of communicable diseases,said Mao Qun'an,spokesperson for the National Health and Family Planning Commission.Although vaccines can provide immunization against certain diseases,they can also cause side effects and result in serious physical harm in some individuals because of a person's health condition,although the chances of developing problems are extremely low,according to experts.
Vaccines stand for the primary means in most countries to prevent and control infectious diseases,and parents should get their children vaccinated as required by the government,said Yu Wenzhou,an expert at the Chinese Center for Disease Control and Prevention.
China is trying to restore public confidence in vaccines

10.A century ago,there were a hundred thousand tigers in the wild.Today,there are barely 3.5thousand.But the picture may not be so hopeless,(61)as.it seems.

7.Four Ways to Be a Great Roommate
Having a roommate can be one of the best experiences in college or,easily,one of the worst.(16)EFollow these tips to avoid the common mistakes that turn good roommate relationships sour.
◇Talk things out.
Communication is key.If something happens,sit down with your roommate and have a face-to-face conversation.I've seen roommate relationships fall apart because something happens and,instead of talking to each other,the two start complaining about their roommates behind their backs.(17)B
◇Don't expect to be best friends.
Some roommates become the best of friends,and some don't.Don't put pressure on yourself or your roommate,especially when you first meet.(18)G   And if your roommate doesn't end up being your best friend,don't worry.
◇(19)D
This applies to food,clothes and anything else.If you want to keep a relationship going,show your roommate that you have respect for what is his or hers by asking first.Even if you both agree to share everything,you should still ask.
◇Clean up after yourself.
This should do without saying.Don't be lazy.Or,at least,don't bury your roommate in your clothes and garbage.Most people I've come across in college are messy.(20)CBut being considerate with where you put your stuff will help you avoid conflict.

A.Think twice before you help your roommates out.
B.This creates nothing but awkward situations and unhappiness.
C.You don't have all the time to clean your room and keep it organized.
D.Ask before you take.
E.It all starts with you to have a good relationship with your roommate.
F.Sometimes you get stuck with someone who has tons of negative energy.
G.Remember,you're trying to make a new friend,not to scare your roommate away.

Officials at Boston College have made what may be a critical decision they've stopped giving out new email accounts to incoming students.The officials realized that the students had already established digital (41)C by the time they entered college,so the new email addresses were just not being used,but,(42)F,the college will offer forwarding (轉(zhuǎn)發(fā)) services.
Starting next year,freshman (43)J  at Boston College won't be given an actual email account complete with login and inbox,just an email address.This address,in the format of johnsmith@bc.edu will simply forward mail to the student's already (44)G inbox,be it Gmail,Windows Live Mail,Yahoo Mail,AOL,or whatever else they may be using.
The college reached a smart decision after first looking into outsourcing(外包) their email to the cloud.While the Boston College decision may have been made for (45)D reasons more than anything,we can easily imagine this as being the start of a new trend.
Can you even imagine a U.S.college student who didn't have an email address of their own by the time they were a freshman?It's (46)H  unheard of.Today's students are digital(47)B  immersed (浸潤) in technology from the day they were born.It simply doesn't make sense to give them yet another account to manage when they enter college.
By going this  (48)I,there are still some challenges to overcome,though.For example,a student who changes their email carrier will probably forget to  (49)E the institution to the change and could then miss out on (50)K  messages from the university with regard to their courses,scholarship,safety information,etc.
In the end,we think the decision Boston College made could easily be the start of a new trend.We're sure the students like it,too.
