B．do chatting
C．had chatted
D．did chatting
解析 此句补充完整为：He spent at least as much time reading as you spent chatting online yesterday.因为前面已出现了一次you spent...，为了避免重复，所以用did代替；spend的用法是：spend time(in)doing sth，所以选用D项。

Ⅱ.阅读理解
Rather than using cellphones to just snap photos of friends or the occasional celebrity sighting, phone users in California may get the chance to track levels of harmful black soot near their workplaces and homes.
Tech companies created a simple circular filter that darkens over time as it absorbs black soot. Anyone with a basic cell phone camera can take a picture of the filter next to a calibration chart (校准图表) that reflects different black soot pollution levels－ no smart phones required.
“We don't need a fancy app for this,_because we just need to be able to email it or SMS it to our system，” said Martin Lukac, a cofounder of the nonprofit Nexleaf Analytics.
Sending the photo via email to an online database allows the cellphone user to get back into about black soot concentration.
The power of that information is that it reflects the individual's exposure to air pollution.
If Nexleaf can get the funding, a select starting group of Californians could track local black soot levels wherever they go during a normal day—local bus stops, community centers, schools or playgrounds.
The nonprofit could also create apps for iPhone or
Android users. But Nexleaf intentionally began with the
lowtech solution for the sake of cellphone users in developing countries.
Regular cooking stoves and other burners of biomass create much of the black soot in developing countries such as India. By contrast, diesel engines in vehicles such as trucks and buses represent the main black
soot culprits in California and the United States—even
if California clean air law has reduced black soot in the
state in the past two decades.
Nexleaf’s filters have already been sent to India. There they helped an effort supported by U. N. called
Project Surya monitor the black soot levels from cleanerburning cooking stoves that were distributed to 500
households.
The darkening Nexleaf filters also gave a clear
warning sign to Indian women about the health danger
of their regular cooking stoves. When they saw the junk
they were breathing in, they were all asking for our
cleanerburning cooking stoves.
【语篇解读】 加利福尼亚州的人们现在可以用他们的手机来测量自己所处的位置的空气的污染程度了。
1．The underlined word“this”in Paragraph 3 refers to________.
A．sending emails to an online database
B．tracking levels of harmful black soot
C．taking a picture of air in workplaces
D．absorbing black soot in the air
解析 代词指代题。根据第一段中的“track levels of harmful black soot”可知，第一段讲的是利用手机来获取空气的污染程度，第二段讲到一个带有照相机的普通手机就可以为空气的污染程度拍照，接着第三段讲到，我们不需要昂贵的装置来获取有关空气的污染程度的信息，下文讲到了原因以及其体的操作流程。
答案 B
2．Why were cellphone users asked to collect information on black soot?
A．To collect data for scientists to make research.
B．To pay attention to its role in changing climate.
C．To realize how seriously they suffer air pollution.
D．To find way of dealing with air pullution.
解析 细节判断题。结合第四段中的“The power of that information is that it reflects the individual's exposure to air pollution”可知答案为C。
答案 C
3．Nexleaf Analytics helps India by giving Indians________.
A．burners of biomass
B．iPhones
C．cellphones
D．cleanerburning cooking stoves
解析 细节判断题。结合倒数第二段中的“cleanerburning cooking stoves that were distributed to 500 households”以及最后一段中的“they were all asking for our cleanerburning cooking stoves”可知这个机构给印度的一些家庭分发了清洁燃烧炉子。
答案 D
4．Indian women asked for cleanerburning cooking stoves because they________.
A．knew the health danger of their regular cooking stoves
B．had to obey the clean air law in India
C．needn't pay for the cleanerburning cooking stoves
D．found it convenient to use the new stoves
解析 细节理解题。从最后一段中的“When they saw the junk they were breathing in...”可知答案为A。
答案 A

Dear_Li_Hong，
Your_letter_reached_me_this_morning.Now_I'd_like_to_share_my_opinion_with_you.
Yes，some high school poor English learners really got good English scores in the junior，but most are those who were too bad at English at that time.So don't
be afraid of falling behind in future.Here are some tips for you.
First of all，be confident that you can learn English well in the senior.Also，review the knowledge learned in the junior before the new school life begins.Besides，make necessary mental preparations for the hard learning in the senior.With more difficult English textbooks，you should preview the text and review in time what has been learned，especially the new words.
Sincerely_hoping_you_can_benefit_from_the_above_and_will_be_a_successful_high_school_English_learner.
Best_wishes!
Yours，
Bruce
