作者： gu QI

LI Zhijun, a platoon leader, was injuredand became blind when he led hismen to remove an unfired gun in1981. Wang Ping was his then fiancee. LiZhijun was in a dilemma-if he told her hehad lost his sight, he was afraid that it woulddevastate her; if not, how long could heconceal the truth? After several days of mentaltorture, he decided to tell her the truth and toask her to leave him.

Currently, there are a variety of researches on corrective feedback, especially on recasts. Most of researches are experiment-based and depend on the certain context. This paper addresses the question of ＂Is recast the most effective form of corrective feedback？＂ by two of Second Language Acquisition （SLA） approaches： cognitive approach and sociolinguistic approach. Empirical research will be used as complement. Theoretically speaking, SLA hypotheses in cognitive approach exist disagreements. Interaction hypothesis favors recast while both input hypothesis and output hypothesis doubt the effectiveness of it. Sociolinguistic approach underscores the significance of appropriate and timely corrective feedback and does not give more credit to certain strategy. Both approaches provide the pedagogical implications and elements to take into account for adopting recasts.

SINCE the Belt and Road Initiative (BRI) was first proposed nearly six years ago, it has been well received globally. So far, 126 countries and 29 international organizations have signed agreements with China for joint construction. Meanwhile, the critics against the BRI among certain media outlets, think tanks, and nongovernmental organizations in some countries have also increased, voicing pessimism and misgivings about it. With debt trap and geopolitical strategy accusations, they exploit sensitive issues among the public in BRI countries concerning sovereignty, energy, and resources to smear the program.

By taking compound 1 as a lead, a series of 5-cyclopropyl substituted cyclic acylguanidine compounds were designed and synthesized as BACE1 inhibitors, compound 4d exhibited 84-fold improved inhibition efficiency than lead compound 1. The diphenyl fragment at the P3 position and the substituents at the second phenyl ring were essential for the compounds to achieve improved inhibition efficiency. This SAR studies provides new insights into the design and synthesis of more promising BACE1 inhibitors for the potential treatment of AD.

Owing to its low electronic noise and flexible target materials, the Spherical Proportional Counter(SPC)with a single electron detection threshold can be utilized to search for sub-GeV dark matter(DM). In this study, we investigate the prospects for light DM direct detection via the DM-nucleus Migdal effect in the DARKSPHERE detector. We consider different DM velocity distributions and momentum-transfer effects. For Xenon and Neon targets, we find that the DM mass mDM can be probed down to as low as m_(DM)~ O(10) MeV, and the derived bounds on the DM-nucleus scattering cross section σ_(n) are sensitive to the high-velocity tails of the DM velocity distribution,which can be altered by orders of magnitude for the different DM velocity distributions in the region mDM< 10MeV.
